What is this page for?

Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy
Leucine+ is a dietary supplement by ALLMAX with 1 active ingredient.We don’t currently list a known drug interaction for its mapped ingredients — but that doesn’t guarantee none exist, so always confirm with your pharmacist.
HelloPharmacist Scorecard of Leucine+ by ALLMAX
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
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
None of the active ingredients could be matched to our evidence database, so intended use can't be graded.
Why this rating?
- None of the active ingredients could be matched to a HelloPharmacist monograph, so intended use can't be graded against our evidence data.
Every active ingredient lists its own amount on the label.
Why this rating?
- The label discloses an exact amount for 1 of its 1 active ingredient.
- No proprietary blends here — you can verify the dose of every single component.
None of the active ingredients could be matched to our interaction database.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was nothing to check interactions against.
None of the active ingredients could be matched to our safety data.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was no safety data to measure.

The ALLMAX advantage: ALLMAX brings you the purest and most powerful crystalline leucine powder with zero binders, excipients, additives or preservatives.
In the final state of leucine production, the result is a coarse crystalline structure. We've taken the raw crystal material and microparticulated it through a complex series of processes, resulting in a perfect, ultra-fine white powder that has optimal absorption levels.

Made in USA with domestic and imported ingredients
Formula
Leucine is likely the best single ingredient supplement on the market to build hard, lean, dense muscle, fast! Leucine is an Essential Branched Chain Amino Acid (BCAA) that is known throughout bodybuilding as the ultimate muscle-builder. It's considered essential because your body cannot product it, so it must be supplied by your diet. Leucine activates an anabolic pathway called mTOR which stimulates muscle protein synthesis. By increasing Leucine consumption the mTOR pathway is activated and protein synthesis is increased. Simply stated, Leucine is essential for achieving a positive nitrogen balance and building lean muscle mass.

Suggested/Recommended/Usage/Directions
Suggested use: One serving (1 scoop) 2 times per day. (Take one serving immediately after intense activity). Serving tip: Pure leucine by nature basically tastes neutral with a slightly tart or bitter taste and does not dissolve immediately in water. We recommend adding it to your ISOFLEX protein shake, a flavored mix or juice such as squeezed lemon with an artificial sweetener like stevia or sucralose. Mixing with an electric blender is recommended.
Precautions
Beware: If you get cheap leucine that dissolves instantly, you may need to be concerned about the source of your leucine. Without additional processing, real leucine does not dissolve easily or quickly.
Warnings: Not recommended for anyone under 18. Keep out of reach of children.
Do not use if pregnant or nursing. Consult a healthcare provider if you have been treated for or diagnosed with a medical condition, or if you are using any medication.
Use only as directed. Do not use if inner seal is broken.
