Good flavor profile, not very sweet

A Staple in My Routine!
I absolutely love this amino complex powder—and honestly, everything from this brand has been amazing so far. The lemon flavor is my go-to; it tastes great, mixes easily with water, and never leaves any gritty texture behind. It’s super refreshing, especially during or after workouts.For the quality of the ingredients and the results I get, the price is more than fair. I haven’t tried the mixed berry flavor yet, but if it’s anything like the lemon, I’m sure it’ll be just as good.Highly recommend if you’re looking for a reliable amino supplement that actually tastes good!

Misleading Ingredients, contains Stevia
It lists Rubaudioside A instead of Stevia extract, which I dislike. Its sweetness is too strong, and it leaves an unpleasant aftertaste. I regret not checking each ingredient before making the purchase.

Good stuff
Good but my son despises the fruit flavor, he prefers the lemon flavor over it.

Nice Amino Acid Complex
A great way to add branch chain amino acids to your diet especially if you avoid animal protein.

Bad aftertaste
I’m pretty sure this product is good but the taste is unbearable. Bad aftertaste and I tried mixing it with some electrolytes but you still taste it. Wouldn’t recommend.

Aluminari –
Good product and we all know BCAAs taste like … but this lemon one is particularly vile. Would buy the brand again, but not the flavour.
Gilbert Esper –
I’ve tried many amino acid supplements over the years, but this Thorne Amino Complex stands out in every way. From the first sip, you can feel the purity and quality – no artificial aftertaste, no weird residue, just clean, refreshing lemon flavor. It mixes perfectly in water and tastes so good.Beyond the taste, the effectiveness is real. My muscle recovery feels faster, my energy during workouts stays strong, and it gives me confidence knowing it’s NSF Certified – meaning tested for purity and banned substances. It’s rare to find a product that tastes this good and works this well.Highly recommended for serious athletes or anyone who cares about what they put into their body. Worth every penny!
