HelloPharmacist Scorecard of Power Carb Unflavored Flavor by Labrada Nutrition

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.

Power Carb Unflavored Flavor contains two active ingredients: sodium and potassium. These are electrolytes — minerals your body needs to keep your heart beating, muscles contracting, and fluids balanced.

The product contains one inactive ingredient, Power Carb (Karbo-Lyn).

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: athletic performance and muscle glycogen loading.
  • We looked for evidence on: Exercise performance, Athletic endurance, Muscle energy metabolism.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We don't hold effectiveness data for potassium in this product. For sodium, the evidence shows it's likely effective for cystic fibrosis and possibly effective for reducing kidney damage from amphotericin B (an antifungal drug).

The evidence isn't established for bipolar disorder or heart failure in our data.

The evidence, ingredient by ingredient Black Psyllium Sodium Potassium

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Sodium is well tolerated in the amounts you'd normally eat, but too much — especially from supplements — is linked to high blood pressure, heart strain, and kidney problems. Potassium from food is safe, but potassium supplements can cause dangerously high blood levels in some people, especially those with kidney disease.

The facts show sodium has conflicting pregnancy and lactation safety data — one entry rates it likely safe, another possibly unsafe — so talk with your doctor or pharmacist before using this during pregnancy or breastfeeding. Potassium is rated likely safe in pregnancy and lactation.

Side effects, ingredient by ingredient Black Psyllium Sodium Potassium

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Black Psyllium, Potassium, Sodium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium.
  • For scale: 2,036 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check before using this if you take blood pressure medications (especially ACE inhibitors, ARBs, or potassium-sparing diuretics), lithium, corticosteroids, water pills, any HIV medications like didanosine, or any other sodium-containing drugs — all are Moderate severity interactions. Your doctor or pharmacist can tell you whether it's okay to use it alongside your specific medications.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is a source of two electrolytes that need careful handling if you take medications for blood pressure, heart rhythm, kidney disease, or bipolar disorder. If you're on any prescription medication, check with your doctor or pharmacist before adding this supplement — sodium and potassium can change how several drugs work and can cause serious imbalances in your blood.

If you have kidney disease, talk it over first.

POWER CARB(TM) Rapid Muscle Glycogen SuperLoader(TM)

What is Power Carb(TM)? Power Carb(TM) is Labrada Nutrition's Designer Carb(TM), a functional carbohydrate "superfood" engineered to rapidly replenish muscle glycogen, increase nutrient uptake, and enhance muscular function. Power Carb(TM) is a nutritional breakthrough that will forever change the way you fuel your muscles. You'll never suffer through a bad workout or flat athletic performance again! What Can Power Carb(TM) Do For Me? Power Carb(TM) can massively increase glycogen stores inside your muscles up to 1200% faster than pasta, rice, or bread. It literally forces glycogen storage, resulting in a huge increase in energy and the ability to exercise harder and longer. And because every gram of glycogen pushed into muscles pulls in 4 grams of water, you can expect your muscles to fully hydrate, with your skin pulled tightly around them, resulting in a more muscular appearance, starting WITH THE FIRST DOSE! How Does Power Carb(TM) Work? Power Carb(TM) is a homopolysaccharide (homogenous, relatively-complex carbohydrate) made up of thousands of monosaccharides (sugar molecules) joined together by glycosidic bonds to form branched macromolecules (large molecules.) The molecular mass (molecule size and weight) of Power Carb(TM) has been engineered to enhance gastric transit through the stomach at a rate much greater than common carbohydrates such as waxy maize, maltodextrins, breads. pasta or rice. Power Carb(TM) is produced from natural complex carbohydrate sources using a newly-developed, patent pending "Enzymatic Milling Process."

Karbo-Lyn(R) is a registered trademark of All American Pharmaceutical.

How Does Power Carb(TM) Increase My Supplement Uptake? Power Carb(TM) increases the effectiveness of any other supplement you take with it. Because Power Carb(TM) passes through the stomach very quickly, it acts like a pump, pulling water and nutrients along with it, which are then shuttled into muscle cells. Nutrient uptake is increased so you get more out of your supplements. Take Power Carb (TM) along with your creatine, BCAA's beta-alanine or other supplements to "express shuttle" them into to your muscles. Is Power Carb(TM) Right for Me? Power Carb(TM) is a powerful performance tool for all athletes including fitness enthusiasts, runners, bicyclists, ball players, tri-athletes, and body builders.

Each ingredient & the kinds of drugs it affects

For each ingredient in Power Carb Unflavored Flavor 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

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.

Likelihood Probable Evidence C
Sodium full monograph & interactions

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.

Power Carb Unflavored Flavor by Labrada Nutrition: Common Questions

Does Power Carb Unflavored Flavor by Labrada Nutrition interact with any medications?
Yes. Based on its ingredients, Power Carb Unflavored Flavor has a known interaction with 2,035 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Power Carb Unflavored Flavor contains 5 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.
Is this product safe during pregnancy?
The data shows conflicting safety ratings for sodium — one says likely safe, another says possibly unsafe — and we don't have enough information to give you a clear answer. Potassium rates as likely safe. Talk with your doctor or pharmacist before using this while pregnant; they can weigh the ingredients against your individual needs.
What are the side effects of potassium from this product?
Potassium is generally well tolerated when you eat it from food, but supplements can cause abdominal pain, belching, diarrhea, nausea, and vomiting. In rare cases, high potassium levels can cause irregular heartbeat, low blood pressure, and mental confusion — which is why it matters to check with your doctor first if you're on certain medications.
Can I take this if I have kidney disease?
No — talk with your doctor or pharmacist first. Sodium and potassium supplements can be risky if your kidneys don't filter electrolytes normally. This is something you need personalized advice on from your own healthcare provider.
Will this raise my blood pressure?
If you take a lot of sodium and you're sensitive to it, yes — high sodium intake is linked to higher blood pressure. If you're already on blood pressure medication, extra sodium can make that medication work less well. Your doctor can advise whether this product fits your situation.
Is it safe to take this with my water pill (diuretic)?
It depends on the type of water pill. Some water pills interact with potassium at Moderate severity and raise the risk of dangerously high potassium levels. Check with your doctor or pharmacist about your specific medication before adding this product.
What is this product meant to do?
Power Carb is a carbohydrate powder — the sodium and potassium in it serve as electrolytes to help with hydration and fluid balance during or after exercise. The effectiveness data we hold shows sodium is likely effective for cystic fibrosis and possibly effective for certain kidney damage, but those aren't the uses this product markets.
