HelloPharmacist Scorecard of Collagen Protein Shake Vanilla flavor by youtheory mens

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 2 of its 9 active ingredients.
  • “Protein Blend” is a proprietary blend — the label gives one combined amount (29.40 Gram(s)) without saying how much of each component you get.
  • “Adaptogen Support Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This shake has 8 active ingredients. The main players are two forms of whey protein — isolate and concentrate — which provide the bulk of the protein.

Hydrolyzed collagen (also called collagen peptides) adds additional protein and is meant to support skin and joint health. Sodium rounds out the mineral content.

The product also includes Maca powder, Ashwagandha powder, and two blended groups: an Adaptogen Support Blend and suma powder (which is part of that blend). There are also two inactive ingredients — natural vanilla flavor and silicon dioxide — used for taste and texture.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: muscle recovery, joint health, skin vitality, and energy.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Exercise-induced muscle soreness, Aging skin, Aging, bone health — and 2 related terms.
  • The strongest evidence on file: Whey Protein is rated "Possibly Effective" for Athletic performance (Natural Medicines).
  • Also on file: Collagen Peptides is rated "Possibly Effective" for Aging skin.
  • Also on file: Maca is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.

Evidence for the main ingredients here is mixed. Whey protein is possibly effective for athletic performance but appears possibly ineffective for bone health.

Hydrolyzed collagen is possibly effective for aging skin and dry skin, though possibly ineffective for muscle strength. Ashwagandha shows possibly effective evidence for insomnia, anxiety, stress, and generalized anxiety disorder.

Maca and astragalus carry insufficient evidence for the conditions they're marketed for in the data we hold — meaning studies haven't established what they do. Suma has no effectiveness ratings on file.

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.

Whey protein is generally well tolerated by most healthy adults, though side effects like bloating, cramps, diarrhea, headache, nausea, and reflux can occur and tend to be dose-related. A small number of users have reported acne or worsening acne.

Ashwagandha is generally well tolerated short-term in healthy adults, but long-term safety data are limited. Common mild side effects include diarrhea, nausea, and vomiting at higher doses.

Rare cases of liver problems have been reported. Sodium is fine in normal dietary amounts, but too much is linked to high blood pressure and heart strain — avoid sodium supplements without medical advice.

Hydrolyzed collagen may rarely cause nausea, heartburn, diarrhea, or gas. Maca, suma, and astragalus are generally well tolerated, though safety data in supplement amounts are limited.

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?
  • 5 of the 8 matched ingredients can interact with medications — Black Psyllium, Whey Protein, Ashwagandha, Astragalus, Sodium.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium; Parkinson's medications.
  • For scale: 2,239 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 your medications if you take levodopa (Major severity); blood pressure drugs, lithium, diabetes medications, thyroid hormone, sedatives, benzodiazepines, immunosuppressants, or liver-toxic drugs (all Moderate); quinolone or tetracycline antibiotics, or bisphosphonates for bone health (Moderate); or corticosteroids (Moderate).

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This shake is a protein-focused product that also includes adaptogens like ashwagandha. If you take levodopa for Parkinson disease, blood pressure medication, lithium, diabetes drugs, thyroid hormone, or immunosuppressants, check with your pharmacist before starting.

Even if you don't take those, it's smart to run your full medication list through the checker on this page because of the high total interaction count.

Each ingredient & the kinds of drugs it affects

For each ingredient in Collagen Protein Shake Vanilla 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

Adaptogen Support Blend3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, jiaogulan might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research suggests that jiaogulan has antiplatelet effects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, jiaogulan might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research shows that jiaogulan can lower blood glucose levels.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, jiaogulan might decrease the effectiveness of immunosuppressive therapy.
Clinical and animal studies suggest that jiaogulan can stimulate the immune system.

Likelihood Possible Evidence D
Adaptogen Support Blend 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

Whey Protein isolate4 drug types · 53 drugs

Levodopa

Theoretically, whey protein might decrease levodopa absorption.
Small clinical studies show that concomitant ingestion of protein or high doses of leucine or isoleucine (100 mg/kg) and levodopa can exacerbate tremor, rigidity, and the "on-off" syndrome in patients with Parkinson disease.

Likelihood Probable Evidence D
Bisphosphonates

Theoretically, whey protein might reduce the absorption of bisphosphonates.
Whey protein contains minerals such as calcium that bind bisphosphonates in the gut. Advise patients to take bisphosphonates at least 30 minutes before whey protein, but preferably at a different time of day.

Likelihood Probable Evidence D
Quinolone Antibiotics

Theoretically, whey protein might decrease quinolone absorption.
Whey protein contains minerals, such as calcium, that can bind to quinolones in the gut. To avoid this interaction, advise patients to take oral quinolones at least 2 hours before or 4-6 hours after whey protein.

Likelihood Probable Evidence D
Tetracycline Antibiotics

Theoretically, whey protein might decrease tetracycline absorption.
Whey protein contains minerals, such as calcium, that bind to tetracyclines in the gut. To avoid this interaction, advise patients to take oral tetracyclines at least 2 hours before or 4-6 hours after whey protein.

Collagen Protein Shake Vanilla flavor by youtheory mens: Common Questions

Does Collagen Protein Shake Vanilla flavor by youtheory mens interact with any medications?
Yes. Based on its ingredients, Collagen Protein Shake Vanilla flavor has a known interaction with 2,254 medications, including 5 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Collagen Protein Shake Vanilla flavor 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.
Is this safe to take if I'm pregnant?
The data show that ashwagandha is likely unsafe in pregnancy, so we'd advise against it. Maca and astragalus don't have enough safety information in pregnancy — talk with your doctor or pharmacist before using. Whey protein, hydrolyzed collagen, and suma have no pregnancy data on file, so ask your provider for personalized advice.
Can I take this while breastfeeding?
Ashwagandha isn't recommended while breastfeeding — safety data are lacking. Maca, suma, and astragalus also don't have enough safety information during lactation. Whey protein, hydrolyzed collagen, and sodium have no breastfeeding data on file. Check with your doctor or pharmacist before starting.
What's ashwagandha doing in a protein shake?
Ashwagandha is an adaptogen — a plant used traditionally to help the body manage stress and support sleep and mood. It's included here as a wellness ingredient alongside the protein for recovery.
Will this shake cause acne?
Whey protein has been linked to acne or worsening acne in some people — case reports show it mostly in teenagers and young adults, and stopping whey usually cleared the acne. Most users don't experience this, though bloating, cramps, and digestive upset are more common dose-related side effects.
Is there a lot of sodium in this shake?
The product facts don't specify how much sodium is in each serving, so check the nutrition label on the package. If you take blood pressure medication, lithium, or diabetes drugs, high sodium intake can interfere with how they work — talk with your pharmacist about your daily sodium total.
What's the collagen supposed to do?
Hydrolyzed collagen in this product is possibly effective for aging skin and dry skin. Evidence for muscle strength is possibly ineffective based on the data we hold.
