What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 19 of its 19 active ingredients.
  • “Huperzine A” is listed as a grouped ingredient — the label gives one combined amount (50 mcg) without saying how much of each component you get.
  • “Branched-Chain Amino Acids” is listed as a grouped ingredient — the label gives one combined amount (6 Gram(s)) without saying how much of each component you get.
  • “Build: Full Spectrum EAA-BCAA Matrix” is a proprietary blend — the label gives one combined amount (8.20 Gram(s)) without saying how much of each component you get.

Alpha EAA Grape Berry Crush is a powder supplement containing 19 ingredients, of which the active components include essential amino acids (L-leucine, L-isoleucine, L-lysine hydrochloride, L-valine, L-threonine, L-tryptophan, L-histidine, DL-phenylalanine, and DL-methionine), minerals (sodium and calcium phosphate), and several herbal and nutrient compounds: taurine, ashwagandha (KSM-66), alpha-GPC (L-alpha glycerylphosphorylcholine), choline, and coconut water (CocoPure). The product also includes inactive ingredients such as flavoring and fruit and vegetable juice.

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
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: amino acids energy and exercise performance.
  • We looked for evidence on: Athletic performance, Cognitive function, Muscle recovery, Endurance, Mental clarity, Fatigue.
  • The closest evidence on file: Choline is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Lysine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.
  • Also on file: L-tryptophan is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.

The evidence for this product's ingredients is mixed and depends on the specific claimed use. For amino acids, L-lysine is possibly effective for cold sores, while L-threonine was found possibly ineffective for ALS.

L-tryptophan is possibly ineffective for depression. Calcium phosphate is effective for kidney failure and dyspepsia, and likely effective for osteoporosis.

Taurine is possibly effective for congestive heart failure and hepatitis. Ashwagandha shows possibly effective evidence for insomnia, anxiety, stress, and generalized anxiety disorder.

Alpha-GPC is possibly effective for Alzheimer disease. For many other uses — athletic performance, cognitive function, growth — the evidence we hold is insufficient to rate.

This is a multi-ingredient product with no single labeled health claim, so effectiveness depends entirely on your intended use.

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 11 of the 12 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 12 of 12.
  • General safety write-ups exist for 12 of 12.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these ingredients are generally well tolerated at typical doses. Sodium in normal dietary amounts is fine, but too much is linked to high blood pressure and heart strain — avoid sodium supplements or very high intake without medical advice.

Calcium is generally safe at recommended amounts; common side effects include constipation and stomach upset. L-lysine is generally well tolerated but may cause abdominal pain or diarrhea at high doses.

Ashwagandha is generally well tolerated short-term in healthy adults, though it carries rare reports of liver damage. L-tryptophan has a history — in the late 1980s, contaminated batches caused a serious neurological condition (eosinophilia-myalgia syndrome), though modern products are not linked to this risk.

L-tryptophan commonly causes drowsiness, headache, and nausea. Regarding pregnancy and breastfeeding: calcium is likely safe in pregnancy at recommended doses; L-lysine safety is not well studied in pregnancy, so check with your doctor first; ashwagandha is traditionally thought to risk miscarriage and should be avoided; L-tryptophan has mixed data — pregnancy ratings vary by source, so discuss with your provider; choline is likely safe in pregnancy if used as directed by your doctor.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 11 of the 12 matched ingredients can interact with medications — Toothed Clubmoss, Lysine, L-tryptophan, Choline, Calcium, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 1,525 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 with your pharmacist or doctor before taking this if you use any of the following: HIV integrase inhibitors (dolutegravir, elvitegravir), blood pressure medications, thyroid medication (levothyroxine), lithium, diabetes drugs, sedatives or sleep aids, antidepressants or other mood medications, heart rhythm drugs, or immunosuppressants. Calcium in this product can reduce absorption of some antibiotics and other drugs, so timing matters.

The bottom line

Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This is a branched-chain amino acid and electrolyte supplement aimed at muscle recovery and hydration. If you take blood pressure medications, lithium, thyroid drugs, diabetes medications, sleep aids, antidepressants, or HIV drugs, talk to your pharmacist or doctor before adding this — several ingredients need careful timing or dose adjustment with those medications.

Pregnant or breastfeeding individuals should check with their provider first, especially because of ashwagandha and L-tryptophan.

KSM-66 Ashwagandha root extract10 drug types · 1,372 drugs

Antidiabetes Drugs

Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.

Likelihood Possible Evidence D
Benzodiazepines

Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.

Likelihood Possible Evidence D
Thyroid Hormone

Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.

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

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.

Likelihood Possible Evidence D
Serotonergic Drugs

Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin. [References: - Effects of Withania somnifera (Ashwaga ndha) on Stress and the Stress-Related Neuropsychiatric Disorders Anxiety, Depression, and Insomnia. Curr Neuropharmacol. 2021 Sep 14; 19: 1468–1495. - A Prospective, Randomized Double-Blind, Placebo-Controlled Study of Safety and Efficacy of a High-Concentration Full-Spectrum Extract of Ashwagandha Root in Reducing Stress and Anxiety in Adults. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3573577/]

Likelihood Possible Evidence C

L-Tryptophan2 drug types · 394 drugs

Cns Depressants

Theoretically, concomitant use of L-tryptophan with CNS depressants might cause additive sedative effects.
Clinical research shows that L-tryptophan can cause fatigue and drowsiness.

Likelihood Probable Evidence B
Serotonergic Drugs

Theoretically, combining L-tryptophan with serotonergic drugs might cause additive serotonergic effects.
L-tryptophan is a precursor to serotonin. Theoretically, combining serotonergic drugs with L-tryptophan might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders.

Likelihood Possible Evidence D

CocoPure3 drug types · 279 drugs

Antihypertensive Drugs

Theoretically, taking coconut water with antihypertensive drugs might increase the risk of hypotension.
Preliminary clinical research shows that drinking coconut water might lower systolic and diastolic blood pressure in patients with hypertension.

Likelihood Possible Evidence D
Quinolone Antibiotics

Many quinolone antibiotics, such as ciprofloxacin and levofloxacin, may have reduced absorption when taken with calcium-containing products due to chelation. It is generally recommended to take quinolones at least 2 hours before or 6 hours after consuming oral products that contain calcium. The calcium content of coconut water varies by product but is generally between 100mg-300mg per 1,000mL. Consumption of a small amount of coconut water may be safe but it would be prudent to avoid drinking large amounts at the same time as a quinolone antibiotic. Reference: https://www.accessdata.fda.gov/drugsatfda_docs/label/2016/019537s086lbl.pdf

Likelihood Probable Evidence A
Antidiabetes Drugs

Theoretically, taking coconut water with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that coconut water might increase insulin levels and/or decrease blood glucose levels.

Likelihood Unlikely Evidence D

Huperzine A2 drug types · 219 drugs

Anticholinergic Drugs

Theoretically, huperzine A might decrease the effects of anticholinergic drugs.
Huperzine A has acetylcholinesterase (AChE) inhibiting effects. In animal models, huperzine A reversed cognitive deficits induced by scopolamine, an anticholinergic drug.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, concurrent use of huperzine A with cholinergic drugs might increase the effects and side effects of these medications.
Huperzine A can inhibit acetylcholinesterase (AChE) and might cause cumulative effects if used with cholinergic drugs.

Likelihood Possible Evidence B

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

Taurine2 drug types · 173 drugs

Antihypertensive Drugs

Theoretically, taurine might increase the risk of hypotension when taken with antihypertensive drugs.
Some clinical evidence suggests that taurine can reduce both systolic and diastolic blood pressure.

Likelihood Probable Evidence D
Lithium

Theoretically, taurine might reduce excretion and increase plasma levels of lithium.
Taurine is thought to have diuretic properties, which might reduce the excretion of lithium.

Likelihood Probable Evidence D

Alpha GPC powder1 drug type · 16 drugs

Scopolamine (Transderm Scop)

Theoretically, alpha-GPC might decrease the effects of scopolamine.
A small clinical study shows that alpha-GPC can partially counteract the attention and memory impairment effects caused by scopolamine given intramuscularly. Whether alpha-GPC can decrease the beneficial anti-motion sickness effects of the scopolamine patch (Transderm Scop) is unclear.

Likelihood Possible Evidence B

VitaCholine1 drug type · 16 drugs

Atropine

Theoretically, choline might decrease the effects of atropine in the brain.
Animal research shows that administering choline one hour before administering atropine can attenuate atropine-induced decreases in brain levels of acetylcholine. Theoretically, concomitant use of choline and atropine may decrease the effects of atropine.

Likelihood Possible Evidence D

L-Threonine1 drug type · 3 drugs

Nmda Antagonists

Theoretically, threonine might decrease the effects of NMDA antagonists.
Threonine increases central nervous system (CNS) glycine levels. Glycine seems to bind a site on NMDA receptors and enhance the activity of the receptors.

Likelihood Likely Evidence B

L-Lysine Hydrochloride1 drug type · 1 drug

5-Ht4 Agonists

Theoretically, lysine may reduce the effects of 5-HT4 agonists.
Animal research suggests that L-lysine is a partial serotonin receptor 4 (5-HT4) antagonist and inhibits diarrhea induced by the 5-HT4 agonist, 5-hydroxytryptophane.

Alpha EAA Grape Berry Crush by NutraBio: Common Questions

Does Alpha EAA Grape Berry Crush by NutraBio interact with any medications?
Yes. Based on its ingredients, Alpha EAA Grape Berry Crush has a known interaction with 1,524 medications, including 258 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Alpha EAA Grape Berry Crush contains 16 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.
Does this product have any fillers or additives I should know about?
The product contains inactive ingredients: flavoring and fruit and vegetable juice. These are not fillers in the harmful sense — they're used for taste and color. If you're sensitive to any of those, check the full label or contact the manufacturer for more detail.
Can I take this if I'm pregnant or breastfeeding?
Pregnancy and breastfeeding safety varies by ingredient in this product. Calcium and choline are likely safe at recommended doses during pregnancy if advised by your doctor. Ashwagandha should be avoided in pregnancy. L-tryptophan has mixed safety data. L-lysine safety is not well studied. Talk with your doctor or pharmacist before starting — it's an individual medical decision.
What are the amino acids in this product for?
Essential amino acids support muscle protein synthesis, recovery after exercise, and overall tissue repair. Branched-chain amino acids (leucine, isoleucine, valine) in particular are thought to aid muscle recovery. However, evidence for athletic performance boost is limited for most of these.
Is ashwagandha in this product safe for long-term use?
Ashwagandha is generally well tolerated short-term in healthy adults, but long-term safety data are limited. There are rare case reports of liver damage, so if you have liver disease or take drugs that affect the liver, mention this product to your doctor. Common side effects at normal doses are uncommon, but diarrhea, nausea, and drowsiness can occur.
Why is there sodium in a sports supplement?
Sodium helps with electrolyte balance and hydration during and after exercise — it's a normal part of sports drinks and electrolyte formulas. However, if you take blood pressure medication or lithium, high sodium intake can be a problem, so check with your pharmacist about the sodium amount in this product and whether it fits your diet.
Can this supplement cause drowsiness?
Yes, potentially. L-tryptophan commonly causes drowsiness and fatigue, and ashwagandha can have sedative effects. If you're sensitive to either, or if you take sedating medications or sleep aids, start with a small amount and see how you react, or talk to your pharmacist first.
