What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 7 of its 9 active ingredients.
  • “Muscle & Nutrient Maximizer” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “Joint & Recovery Complex” is a proprietary blend — the label doesn't break down how much of each component you get.
  • “Fast-Acting Proprietary Blend (Herb/Botanical)” is a proprietary blend — the label gives one combined amount (250 mg) without saying how much of each component you get.

This powder contains 8 ingredients, of which the labeled actives are sodium, vitamin D3, potassium, hyaluronic acid, leucine, Chinese Skullcap Root Extract, Cutch Tree Bark Extract, and glutamine. Three of these are labeled as proprietary blends (Muscle & Nutrient Maximizer, Joint & Recovery Complex, and Fast-Acting Proprietary Blend), so their exact component ingredients and amounts are not fully disclosed.

The remaining inactive ingredients are excipients like protein blend, natural and artificial flavors, gum blend, waxy maize starch, lecithin, sucralose, and acesulfame potassium.

Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: post-workout muscle recovery and performance.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Exercise-induced muscle soreness, Muscle protein synthesis, Anabolic response.
  • The closest evidence on file: Glutamine is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Catechu is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness.
  • Also on file: Glutamine is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle damage.

The evidence for this product's ingredients is mixed. Vitamin D3 is rated Effective for rickets, osteomalacia, renal osteodystrophy, hypoparathyroidism, and familial hypophosphatemia — well-established uses.

Glutamine is rated Effective for sickle cell disease and Possibly Effective for HIV/AIDS-related wasting and recovery from surgery or critical illness. Hyaluronic Acid is rated Possibly Effective for dry eye and venous leg ulcers.

For the other ingredients and proprietary blends in this product, effectiveness ratings are either not established in the data we hold or rated as Insufficient Reliable Evidence. This product's claim as a muscle recovery aid is not covered by the evidence summaries available to us.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 8 of the 8 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 8.
  • General safety write-ups exist for 8 of 8.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Sodium is generally well tolerated at normal dietary levels, but high intake is linked to high blood pressure and heart strain — excess sodium can worsen cardiovascular and kidney disease in rare cases. Vitamin D3 is generally safe at recommended doses; very high doses over time can cause toxicity with symptoms of high calcium levels (hypercalcemia).

Potassium from food is fine, but supplements can cause dangerously high blood levels (hyperkalemia), especially in people with kidney disease, and may cause abdominal pain, nausea, diarrhea, or vomiting. Hyaluronic Acid appears well tolerated orally, though long-term supplement safety is not fully studied.

Chinese Skullcap Root Extract and Cutch Tree Bark Extract are generally well tolerated orally, but human safety data are limited; the specific combination product Limbrel (containing both) has been linked to rare reports of serious liver and lung injury. Glutamine is generally well tolerated in healthy adults but may cause bloating, gas, nausea, diarrhea, or headache, and should be used only under medical supervision in people with kidney or liver disease.

Each ingredient & the kinds of drugs it affects

For each ingredient in Amplified Total Muscle Recovery Vanilla with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Dietary Fiber7 drug types · 2,025 drugs

Carbamazepine (Tegretol)

Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Lithium

Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Metformin (Glucophage)

Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.

Likelihood Possible Evidence D
Olanzapine (Zyprexa)

Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.

Likelihood Unlikely Evidence B
Ethinyl Estradiol

Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

Likelihood Possible Evidence B
Dietary Fiber full monograph & interactions

Joint & Recovery Complex18 drug types · 1,136 drugs

Warfarin (Coumadin)

Concomitant use with cannabis seems to increase the levels and clinical effects of warfarin.
In vitro research shows that the cannabis constituents delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol inhibit the cytochrome P450 2C9 (CYP2C9)-mediated 7-hydroxylation of S-warfarin in a concentration-dependent manner.
Additionally, there are multiple case reports of patients chronically taking warfarin that developed a spike in international normalized ratio (INR) after using cannabis in various forms, including smoking cannabis, taking medical cannabis orally, or drinking water infused with cannabis flower. One patient smoked 2-2.5 grams in one week and another patient had doubled the amount of THC consumed from 7.5 mg to 14.7 mg daily for one week.

Likelihood Probable Evidence D
Alcohol (Ethanol)

Theoretically, cannabis might have additive effects when used with alcohol.
Cannabis can have CNS depressant effects, similar to synthetic delta-9-tetrahydrocannabinol (THC). Theoretically, concomitant use of alcohol with cannabis can have additive effects including psychomotor impairment, sedation, and changes in mood and behavior.

Likelihood Possible Evidence D
Anesthesia

Cannabis use might alter the safety and clinical effects of various forms of anesthesia.
A small clinical study shows that higher doses of propofol may be needed to achieve relaxation and loss of consciousness in chronic cannabis users compared with nonusers. Another small clinical study shows that use of cannabis within 72 hours prior to undergoing surgery requiring atropine anesthesia may increase the risk of sustained postoperative tachycardia. The exact mechanisms of these interactions are unclear. Obtain a patient's history of cannabis use preoperatively and advise patients to discontinue cannabis use for at least 2 weeks prior to undergoing surgery.

Likelihood Possible Evidence B
Anticoagulant/Antiplatelet Drugs

Theoretically, cannabis might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In vitro research shows that the cannabis constituents delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) inhibit platelet aggregation.

Likelihood Possible Evidence D
Barbiturates

Theoretically, cannabis might increase the levels and adverse effects of barbiturates.
Some research shows that synthetic delta-9-tetrahydrocannabinol (THC) increases the elimination half-life of pentobarbital by 4 hours when dosed concomitantly.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, cannabis might have additive effects if used with other CNS depressants.
Cannabis can have CNS depressant effects. Combining cannabis with other CNS depressants might result in additive or synergistic effects. A small clinical trial in healthy adults shows that inhaling a high-grade cannabis (Bedrocan International B.V., Veendam, The Netherlands) 100 mg, containing delta-9-tetrahydrocannabinol 21.8% and cannabinol 0.1%, modestly increases subjective feelings of sedation when compared with cannabis alone.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Cannabis may increase levels of drugs metabolized by CYP2C19.
Research shows that cannabidiol (CBD), a constituent of cannabis, inhibits CYP2C19. In clinical studies and case reports, cannabidiol use resulted in significant increases in the serum levels of topiramate, methadone, citalopram, omeprazole, and N-desmethylclobazam, the primary active metabolite of clobazam. These chemicals are metabolized by CYP2C19. Concomitant use of cannabis with CYP2C19 substrates may increase the risk for adverse effects from these substrates.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Inducers

Theoretically, drugs that are CYP2C9 inducers might decrease the effects of cannabis.
Delta-9-tetrahydrocannabinol (THC), an active constituent of cannabis, is a substrate of CYP2C9 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Inhibitors

Theoretically, drugs that are CYP2C9 inhibitors might increase the adverse effects of cannabis.
Delta-9-tetrahydrocannabinol (THC), an active constituent of cannabis, is a substrate of CYP2C9 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, cannabis might increase the levels and adverse effects of CYP2C9 substrates.
In vitro research shows that the cannabis constituents delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol moderately inhibit the CYP2C9-mediated 7-hydroxylation of S-warfarin in a concentration-dependent manner. In vitro research also shows that cannabis extracts modestly inhibit the CYP2C9 metabolism of tolbutamide; extracts providing the specific cannabinoids CBD and cannabigerol (CBG) had stronger inhibitory effects than extracts containing THC and CBD.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, cannabis might decrease the levels and clinical effects of CYP2E1 substrates.
In vitro research shows that cannabis can induce the activity of CYP2E1, which might increase the metabolism of CYP2E1 substrates.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Inducers

Theoretically, CYP3A4 inducers might reduce the levels and clinical effects of cannabis.
Delta-9-tetrahydrocannabinol (THC), an active constituent of cannabis, is a substrate of CYP3A4 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Inhibitors

Theoretically, CYP3A4 inhibitors might increase the levels and adverse effects of cannabis.
Delta-9-tetrahydrocannabinol (THC), an active constituent of cannabis, is a substrate of CYP3A4 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, cannabis may increase the levels and adverse effects of CYP3A4 substrates.
In vitro research shows that cannabis can inhibit the activity of CYP3A4 enzymes, which might decrease the metabolism of CYP3A4 substrates. In vitro research also shows that cannabis extracts modestly inhibit the CYP3A4 metabolism of testosterone; extracts providing the specific cannabinoids CBD and cannabigerol (CBG) had stronger inhibitory effects than extracts containing THC and CBD.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, cannabis might alter levels of drugs that are substrates of P-glycoprotein (P-gp).
Most in vitro research suggests that constituents of cannabis, including cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC), can inhibit P-gp and increase the accumulation of probe compounds by reducing P-gp mediated drug efflux. In vitro studies in kidney cell lines show that a 1-hour exposure to CBD and THC inhibits P-gp. Cannabis may also alter the expression of P-gp, although this effect appears to vary based on duration of exposure. Some in vitro research in lymphoblastoid leukemia cell lines indicates that a 1-hour exposure to cannabinoids does not affect P-gp expression, while a prolonged 72-hour exposure decreases P-gp expression. Other in vitro research in these cell lines shows that a 4-hour exposure to THC and CBD induces P-gp gene expression, while exposure for longer than 4 hours and up to 48 hours does not induce P-gp gene expression.

Likelihood Possible Evidence D
Theophylline

Smoking cannabis while taking theophylline might reduce the levels and clinical effects of theophylline.
Similar to smoking tobacco, smoking cannabis seems to increase the metabolism of theophylline.

Likelihood Possible Evidence D
Thrombolytic Drugs

Cannabis might augment the effects of thrombolytic drugs and increase the risk of severe bleeding.
A case of cerebral hemorrhage has been reported for a 51-year-old female and chronic cannabis user who had consumed a large amount of cannabis prior to receiving recombinant tissue plasminogen activator (rtPA) for ischemic stroke. Hemorrhage had been ruled out prior to providing the rtPA. The exact mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Antipsychotic Drugs

Cannabis does not seem to affect blood levels or effects of some antipsychotic drugs.
Human research shows that cannabis use does not affect blood levels or clinical effects of amisulpride, aripiprazole, or olanzapine in patients with schizophrenia and related disorders.

Likelihood Unlikely Evidence B
Joint & Recovery Complex full monograph & interactions

Vitamin D38 drug types · 715 drugs

Aluminum

Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.

Likelihood Probable Evidence B
Atorvastatin (Lipitor)

Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.

Likelihood Probable Evidence B
Calcipotriene (Dovonex)

Taking calcipotriene with vitamin D increases the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.

Likelihood Probable Evidence D
Digoxin (Lanoxin)

Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.

Likelihood Possible Evidence D
Diltiazem (Cardizem, Others)

Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.

Likelihood Probable Evidence B
Thiazide Diuretics

Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.

Likelihood Probable Evidence D
Verapamil (Calan, Others)

Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.

Sodium7 drug types · 205 drugs

Antihypertensive Drugs

Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.

Likelihood Probable Evidence A
Corticosteroids

Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.

Likelihood Possible Evidence D
Didanosine (Videx)

Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.

Likelihood Probable Evidence C
Lithium

Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.

Likelihood Probable Evidence B
Sodium Phosphates

Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Sodium-Containing Drugs

Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Tolvaptan (Samsca)

Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.

Potassium3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

Amplified Total Muscle Recovery Vanilla by GNC Pro Performance AMP: Common Questions

Does Amplified Total Muscle Recovery Vanilla by GNC Pro Performance AMP interact with any medications?
Yes. Based on its ingredients, Amplified Total Muscle Recovery Vanilla has a known interaction with 2,251 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Amplified Total Muscle Recovery Vanilla contains 8 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What does hyaluronic acid do in this product?
Hyaluronic acid is included as a joint and recovery component. It has been studied for dry eye and wound healing, though the evidence for other uses is insufficient. In supplement form, its long-term safety hasn't been fully studied.
Is this product safe to use while pregnant?
Not without talking to your doctor first. Sodium is possibly unsafe in pregnancy, and we don't have enough safety data on Chinese Skullcap Root Extract and Hyaluronic Acid to recommend them during pregnancy. Vitamin D3 and potassium are considered likely safe at recommended doses, but your doctor should review the entire product for your specific situation.
What are the side effects I might expect?
The most common side effects from these ingredients are gastrointestinal — bloating, gas, nausea, diarrhea, or abdominal pain. High sodium intake can raise blood pressure. At normal doses, vitamin D3, potassium, and glutamine are generally well tolerated, but excessive amounts can cause more serious problems like high calcium or potassium levels.
Can I use this if I'm on a diuretic for my heart?
Not without checking with your doctor or pharmacist first. This product contains potassium, which can dangerously raise blood levels if you're on a potassium-sparing diuretic. Sodium also interacts with several heart and blood pressure medications. Use the medication checker on this page with your exact drugs.
Why is sodium in a muscle recovery supplement?
Sodium is included because it plays a role in muscle contraction and fluid balance during exercise. At normal dietary amounts it's fine, but this product adds to your total sodium intake for the day — something to keep in mind if you're watching your salt intake or taking blood pressure medication.
What's glutamine supposed to do?
Glutamine is an amino acid that may support recovery after intense exercise or illness. It's rated effective for sickle cell disease and possibly effective for HIV-related wasting and post-surgery recovery. For general muscle recovery in healthy people, the evidence isn't established in the data we hold.
