Amino Max Ingredients

The ingredient profile of Amino Max is very similar to many other BCAA/Amino supplements out there…


Leucine is the most potent amino acid when it comes to stimulating protein synthesis.  It works by activating mTOR, a signaling molecule that directly controls muscle protein synthesis rates.  Leucine is actually the only one of the three branched chain amino acids that has any sort of meaningful impact on muscle growth, so it’s important that it be dosed appropriately.

Clinically, Leucine has been shown to increase muscle protein synthesis and/or reduce muscle breakdown in the range of 3-5g/day, but Six Star Amino Max unfortunately contains just 2g per serving.  Users will need 2 servings to yield a clinically proven 4g dose of Leucine.


Isoleucine has no direct muscle-building properties, but it does appear to be able to induce glucose uptake into muscle cells and reduce blood glucose levels.  This would certainly be considered a benefit, but studies in humans are scarce and there isn’t really a known dosing range.

Amino Max contains 1g of Isoleucine, a standard dose as far as most BCAA supplements go.


Valine is probably the most useless of the three BCAAs, but preliminary research indicates that it may be useful for delaying fatigue.  Of course, this is purely theoretical, with no studies directly demonstrating anything.  Still, it’s not a complete BCAA supplement without Valine so, in the context of Amino Max, it fits.


Glutamine has long been combined with BCAA supplements and has a long list of claims attached to it, most of which have turned out to be false.  Glutamine does not improve exercise performance or meaningfully increase muscle growth.

There is some borderline theoretical research which indicates that Glutamine may be helpful for people who exercise for more than a few hours at a time (like marathon runners), but it’s not going to be of much use if you’re just hitting the gym for an hour a day.

Taurine, though way overused and often exaggerated, is actually quite effective as a recovery aid.  It has been shown to reduce exercise induced oxidative damage in multiple human studies.  Often times, supplements companies claim that Taurine enhances exercise performance, but this effect isn’t entirely reliable.

What is reliable is Taurine’s recovery-enhancing properties which ultimately make it a worthy addition to any BCAA/Amino/Intra-Workout supplement such as Amino Max.

Amino Max contains 1g, a standard dose compared to other BCAA supplements.

Amino Max Ingredient Takeaway

Amino Max is under-dosed on a per serving basis so you’ll need 2 servings if you want to get a clinical dose of Leucine.  Other than that, there’s really nothing special about it.  It’s very similar to just about every other BCAA supplement out there, but if you don’t mind taking two servings at a time, it’s not bad.

Is Amino Max Safe?

Yes, Amino Max is entirely safe, even at two servings.  This is because there are no stimulants in the formula and all the ingredients are quite well tolerated because they’re just free form amino acids (you eat amino acids all the time in the form of solid protein).

The Bottom Line

Amino Max is more of a two serving BCAA supplement, and at two servings it’s not bad, but if you’re looking for more than just an ordinary BCAA supplement, keep it moving.  This is what you would call a “cookie cutter” formula.  Nothing special, but nothing terrible either.  If you’re looking for a more advanced BCAA supplement, check out our Best BCAA/Amino Supplements List exists to educate the supplement community and seperate the science from the hype.
