HelloPharmacist Scorecard of FitWhey Chocolate by CBD Fit

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

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 3 of its 4 active ingredients.
  • “Full Spectrum Hemp Blend” is a proprietary blend — the label gives one combined amount (16 mg) without saying how much of each component you get.
  • “Hemp Oil extract” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

FitWhey Chocolate contains 3 active ingredients: L-Glutamine (an amino acid that plays a role in muscle and immune function), Hemp Oil (from hemp seeds, which contain protein and other plant compounds), and Cannabidiol — commonly called CBD. The product also contains whey protein isolate as an inactive ingredient, alongside cocoa, sweeteners (coconut palm sugar, cane sugar, stevia), and standard binders and flavorings.

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: post-workout recovery and muscle repair.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Postoperative recovery, Wound healing, Critical illness (trauma), muscle protein synthesis — and 1 related terms.
  • The strongest evidence on file: Glutamine is rated "Possibly Effective" for Critical illness (trauma) (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Effective" for Postoperative recovery.
  • Also on file: Glutamine is rated "Possibly Ineffective" for Athletic performance.

The data we hold shows L-Glutamine is effective for sickle cell disease and possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness recovery. For Hemp Oil, the evidence isn't established — we have insufficient reliable data to rate it for constipation, eczema, or cholesterol.

Cannabidiol's effectiveness isn't rated in our data for this product.

The evidence, ingredient by ingredient Glutamine Black Psyllium Hemp

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.

L-Glutamine is generally well tolerated in healthy adults, but the safety data advises that people with kidney or liver disease use it only under medical supervision. Avoid supplemental doses unless your doctor recommends them.

Common side effects from oral doses include belching, bloating, diarrhea, constipation, nausea, vomiting, headache, and gastrointestinal pain. Rare cases of dizziness have been reported, and two patients with bipolar disorder experienced mania or hypomania on doses up to 4 grams daily.

Hemp seed products in food amounts are generally well tolerated, but concentrated supplements like this are less studied. Serious adverse effects are rare but include anaphylaxis, hives, facial swelling, and shortness of breath in people with hemp seed allergy.

Isolated case reports exist of elevated liver enzymes and hepatitis in a young child given hemp extract. The safety data for pregnancy and lactation with L-Glutamine is rated Likely Safe, but there is no rating on file for Hemp Oil in pregnancy or lactation — talk with your doctor or pharmacist about the risk-benefit before using this product if you're pregnant or breastfeeding.

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, Glutamine, Hemp.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; seizure medications; heart-rhythm medications; lithium.
  • For scale: 2,104 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.

Before taking this product, double-check with your doctor or pharmacist if you're on anticonvulsant medications (seizure drugs) — L-Glutamine may theoretically reduce their effectiveness. Also confirm if you're taking antihypertensive drugs, ACE inhibitors, blood thinners, or antiplatelet drugs, since hemp oil may theoretically lower blood pressure further or increase bleeding risk.

And if you're on medications broken down by CYP1A2 or CYP3A4 enzymes — a broad group including cancer drugs, immunosuppressants, and statins — hemp oil may theoretically speed up how your liver clears them, making them less effective.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glancePartially disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This powder is designed as a protein supplement and may be worth considering if you're interested in amino acid support, though evidence is strongest for L-Glutamine in specific conditions like sickle cell disease. If you take any seizure medications, blood pressure drugs, blood thinners, or medications metabolized by your liver, you'll want to check with your doctor or pharmacist before starting — the interactions are mostly theoretical but worth confirming for your situation.

If you have kidney or liver disease, or a hemp seed allergy, talk it over with your healthcare provider first.

Each ingredient & the kinds of drugs it affects

For each ingredient in FitWhey Chocolate 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

Hemp Oil6 drug types · 938 drugs

Estrogens

Theoretically, hemp might interfere with hormone therapy due to its estrogenic effects.
In an ovariectomized animal model, a diet containing hemp seed 1%, 2%, or 10% resulted in normalized plasma levels of 17-beta-estradiol. The mechanism of action for this effect is unclear.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, consuming hemp seed protein isolate with ACE inhibitors might have additive effects and increase the risk of hypotension.
Hemp seed protein hydrolysate has shown ACE inhibitor-like effects in a hypertensive animal model. However, hempseed oil consumption does not seem to reduce blood pressure in humans. Until more is known, monitor blood pressure and potassium levels.

Likelihood Unlikely Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hemp seed might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In animal research, hemp seed at 5% of the diet inhibits platelet aggregation in vitro. However, in human research, taking hemp seed oil 2 grams daily for 12 weeks does not inhibit the aggregation of platelets in vitro.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, hemp seed protein may have additive effects with antihypertensive drugs.
In a hypertensive animal model, hemp seed protein hydrolysate reduced systolic blood pressure by a mechanism possibly involving the inhibition of renin and angiotensin converting enzyme (ACE) activities. However, there was no effect of hemp seed protein on blood pressure in normotensive animals. Furthermore, hempseed oil consumption does not seem to reduce blood pressure in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

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

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

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

Likelihood Possible Evidence D

L-Glutamine1 drug type · 50 drugs

Anticonvulsants

Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.

FitWhey Chocolate by CBD Fit: Common Questions

Does FitWhey Chocolate by CBD Fit interact with any medications?
Yes. Based on its ingredients, FitWhey Chocolate has a known interaction with 2,103 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
FitWhey Chocolate 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 L-Glutamine safe to take if I'm pregnant or breastfeeding?
The safety data rates L-Glutamine as Likely Safe in pregnancy. However, we advise avoiding supplemental doses while breastfeeding unless your doctor recommends them, because limited safety information exists in that situation. Talk with your doctor or pharmacist about whether this product is right for you.
What are the most common side effects I might experience?
L-Glutamine can cause belching, bloating, diarrhea, constipation, nausea, vomiting, headache, and gastrointestinal pain. Hemp seed products in supplement form are less studied, but serious side effects like anaphylaxis or allergy are rare. If you have a known hemp seed allergy, avoid this product.
Will this help with my sickle cell disease?
L-Glutamine in this product is rated effective for sickle cell disease based on available data. However, this is a supplement, not a replacement for your doctor's treatment plan — talk with your healthcare provider about whether adding it makes sense for your specific situation.
Can this product help with weight loss or muscle building?
The data we hold shows L-Glutamine effectiveness for sickle cell disease and possibly for postoperative and critical illness recovery. Hemp Oil effectiveness isn't established in our data for weight or muscle purposes. For fitness goals, check with your doctor or a registered dietitian about whether this supplement fits your plan.
Is there CBD in this product, and what does it do?
Yes, Cannabidiol (CBD) is listed as one of the 3 active ingredients. However, we hold no interaction data on CBD and no effectiveness ratings for it in our system, so we can't tell you what role it plays in this specific product. Check the label or contact the manufacturer for details on its intended purpose and amount.
Why does the product have so many inactive ingredients?
Whey protein isolate, cocoa, sweeteners, and binders like xanthan gum are added to make the powder taste better, mix smoothly, and provide texture. They don't contribute to the supplement's active effects but are standard in flavored protein powders.
