HelloPharmacist Scorecard of XFit Power by MHP Maximum Human Performance

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

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 5 of its 5 active ingredients.
  • “POWER 24 Hour Muscle Building & Repair System” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

XFit Power contains 5 active ingredients. Two are B vitamins: Vitamin B6 and Vitamin B12, both play roles in energy, nerve function, and metabolism.

The product also includes D-aspartic acid, folate, and a proprietary blend labeled POWER 24 Hour Muscle Building & Repair System. The inactive ingredients are standard tablet components — microcrystalline cellulose, calcium carbonate, stearic acid, and several processing aids — that help form and stabilize the tablet.

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: xtreme fitness intensity training performance.
  • We looked for evidence on: Physical performance, Fatigue, Athletic endurance, Muscle performance.
  • The closest evidence on file: Vitamin B12 is rated "Possibly Ineffective" for Physical performance (Natural Medicines).
  • Also on file: Vitamin B12 is rated "Insufficient Reliable Evidence To Rate" for Fatigue.

The evidence we hold covers only the B vitamins in this product. Vitamin B6 is effective for sideroblastic anemia and B6 deficiency itself, likely effective for high homocysteine (hyperhomocysteinemia), and possibly effective for pregnancy-related nausea and vomiting.

Vitamin B12 is effective for B12 deficiency and Imerslund-Grasbeck disease, likely effective for cyanide poisoning, and possibly effective for canker sores and nerve pain after shingles (postherpetic neuralgia). We hold no effectiveness data for the other ingredients in this product.

The evidence, ingredient by ingredient Vitamin B6 Vitamin B12

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B6 is well tolerated at doses under 100 mg daily, but high doses over time can damage nerves (a condition called sensory neuropathy). Doses above 1,000 mg daily or lifetime totals of 1,000 grams or more carry the highest risk, though nerve damage can occur at lower amounts too.

Common side effects at any dose include headache, nausea, abdominal pain, and loss of appetite. Vitamin B12 is very safe overall — your body excretes excess B12 in urine, so there's no established upper limit.

The most common side effect is injection site soreness if given by needle. Allergic reactions (rash, itching) are rare.

No pregnancy or breastfeeding safety data is on file for either B vitamin in this product; talk with your doctor or pharmacist for guidance if you're pregnant or nursing.

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 2 matched ingredients can interact with medications — Vitamin B12, Vitamin B6.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: Parkinson's medications.
  • For scale: 230 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.

Double-check this product if you take seizure medications (phenobarbital or phenytoin), blood pressure pills, the heart drug amiodarone (Cordarone), levodopa for Parkinson's disease without carbidopa, or metformin for diabetes. The first two seizure drugs and blood pressure medications carry Moderate-severity concerns; the others are Minor.

No interactions are documented for the other ingredients we could not check.

The bottom line

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

XFit Power may work for you if you're looking to support energy and muscle recovery with B vitamins, but it comes with real drug interactions you need to check first — especially if you take seizure medications, blood pressure drugs, or heart medications. If you take metformin for diabetes, be aware that this product's B12 won't offset metformin's effect on B12 levels.

Run your medications through the checker on this page, and talk with your pharmacist before starting.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in XFit Power 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.

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

Likelihood Unlikely Evidence D

Vitamin B121 drug type · 20 drugs

Metformin (Glucophage)

Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.

Does XFit Power by MHP Maximum Human Performance interact with any medications?
Yes. Based on its ingredients, XFit Power has a known interaction with 230 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
XFit Power 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 Vitamin B6 safe at the doses in this product?
Vitamin B6 is well tolerated below 100 mg daily. We don't have the exact dose in XFit Power from the label provided, so check your tablet's strength. High doses over time can harm nerves; the biggest risk is above 1,000 mg daily or lifetime totals over 1,000 grams.
Can I take this if I'm pregnant or breastfeeding?
We don't have pregnancy or breastfeeding safety data on file for the B vitamins in this product. Talk with your doctor or pharmacist — they can give you personalized advice based on your situation.
What's D-aspartic acid in here for?
D-aspartic acid is listed as an active ingredient in XFit Power, likely included to support muscle building and repair, but we hold no published effectiveness data for it. The product label or manufacturer info may explain its role more fully.
What are the most common side effects?
Vitamin B6 can cause headache, nausea, abdominal pain, and loss of appetite. Vitamin B12 is generally very well tolerated; injection site soreness is the main side effect if given by needle rather than taken by mouth.
Is this product gluten-free or free of common allergens?
We hold ingredient and interaction data only — not allergen or dietary restriction info. Check the product label or contact the manufacturer (MHP) for allergen details.
Can I take this with metformin?
Metformin can lower your B12 levels over time and interfere with your body's ability to absorb it. You can take XFit Power with metformin, but your doctor should monitor your B12 levels if you use both long-term.
