HelloPharmacist Scorecard of Plant Complete Chocolate Natural Flavor by ZHOU

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.

From our pharmacy team — supplement deep dive

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 1 of its 3 active ingredients.
  • “Blend” is a proprietary blend — the label gives one combined amount (29 Gram(s)) without saying how much of each component you get.

This powder contains 2 active ingredients: Pea Protein, Fermented and Rice Protein, Fermented — both plant-based protein sources meant to support muscle and general nutrition. The product also includes inactive ingredients like cocoa, vanilla and cream flavorings, Himalayan salt, guar gum, acacia gum, xanthan gum, and stevia leaf extract for taste and texture.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: supports lean muscle mass and post-workout recovery.
  • We looked for evidence on: Exercise-induced muscle damage, Exercise-induced muscle soreness, Muscle strength, Postoperative recovery, Athletic performance, Protein synthesis.
  • The closest evidence on file: Pea Protein is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness (Natural Medicines).
  • Also on file: Pea Protein is rated "Insufficient Reliable Evidence To Rate" for Muscle strength, Postoperative recovery, Exercise-induced muscle damage.
  • Also on file: Rice Protein is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness, Muscle strength.

The evidence supporting these proteins is limited. Rice protein is rated Possibly Effective for food allergies, but for everything else in this product — including exercise-related muscle soreness, muscle strength, blood pressure, cholesterol, and irritable bowel syndrome — the data shows Insufficient Reliable Evidence.

In plain terms, we don't have solid proof these ingredients work for those purposes.

The evidence, ingredient by ingredient Black Psyllium Pea Protein Rice Protein

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.

Pea protein and rice protein are both food-derived and generally well tolerated by most healthy adults. That said, allergic reactions are possible — a small number of children have had severe reactions (including anaphylaxis) to pea protein, especially those with histories of allergies to other legumes or tree nuts.

Rice protein has rarely been reported to cause enterocolitis (bowel inflammation) in infants and young children, and allergies to rice protein itself, though uncommon, have been documented. For pregnancy and breastfeeding, concentrated protein supplements like these haven't been well studied.

The safety data advises checking with your doctor or pharmacist before use, since whole foods are fine but the concentrated forms are uncharted territory.

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?
  • 2 of the 3 matched ingredients can interact with medications — Black Psyllium, Rice Protein.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium.
  • For scale: 2,026 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.

ACE inhibitors (blood pressure medications like lisinopril or enalapril) are the main concern — the rice protein in this formula may increase their blood-pressure-lowering effect. If you take any ACE inhibitor, check with your doctor or pharmacist before starting.

The bottom line

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

If you're looking for a plant-based protein powder and have no allergies to peas or rice, this product is generally well tolerated. If you take an ACE inhibitor for blood pressure, discuss this with your doctor or pharmacist first — the rice protein may amplify its effect.

Anyone with a history of food allergies, especially to legumes or tree nuts, should be cautious and talk it over with their healthcare provider.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in Plant Complete Chocolate Natural 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

Rice Protein, Fermented1 drug type · 23 drugs

Ace Inhibitors (Aceis)

In laboratory research, hydrolyzed rice protein inhibits angiotensin-converting enzyme (ACE). In animal research, the inhibition of ACE is correlated with a reduction in systolic blood pressure. So far, this effect has not been shown in humans. Theoretically, concomitant use of rice protein and ACE inhibitors may increase the risk of blood pressure becoming too low. Use with caution. ACE inhibitors include benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), and trandolapril (Mavik).

Plant Complete Chocolate Natural Flavor by ZHOU: Common Questions

Does Plant Complete Chocolate Natural Flavor by ZHOU interact with any medications?
Yes. Based on its ingredients, Plant Complete Chocolate Natural Flavor has a known interaction with 2,025 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Plant Complete Chocolate Natural Flavor contains 4 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 actually help with muscle soreness or muscle strength?
The evidence isn't established in our data. Both pea and rice protein are rated as having Insufficient Reliable Evidence for exercise-related muscle soreness and muscle strength, so we don't have solid proof they work for those purposes yet.
Can I take this if I'm allergic to peanuts or tree nuts?
Pea and rice proteins are different plants, but people with legume or tree nut allergies have had severe reactions to pea protein in the past. Because of the overlap, it's worth talking to your doctor or pharmacist first — they know your allergy history best.
Is this safe to use while pregnant or breastfeeding?
There isn't enough data to know either way. Whole peas and rice are foods, but concentrated protein supplements like these haven't been well studied in pregnancy or while breastfeeding. Talk with your doctor or pharmacist for personalized advice.
What's the chocolate flavor made from?
The product includes cocoa and natural chocolate, vanilla, and cream flavorings. We don't have detailed sourcing information for those in our data.
Does this have any fillers or artificial ingredients?
The inactive ingredients include gums (guar, acacia, and xanthan) for texture, stevia leaf extract for sweetness, Himalayan salt, and natural flavorings — no artificial sweeteners or major fillers listed.
Is rice protein hypoallergenic?
Rice protein is often called hypoallergenic, but allergies to rice protein have been reported when eaten or applied to skin. It's rare, but it does happen — especially in young children — so if you have a history of food allergies, mention it to your doctor or pharmacist.
