Good source for muscles and longevity
Second time buying this - first I tried berry flavor, now lemon- both taste great and the product dissolves well in water. As a menopausal, vegetarian woman I am always looking for more protein sources and am excited to find this as I'm not always in the mood for my protein shake every day. The flavors are however a bit strong so I use half a packet daily in about 12-14 oz water and am able to add my mushroom tincture and chlorophyll drops for a supercharged "tonic". Might be psychosomatic but I do feel like after taking it for 6 weeks it's helping my muscle mass - I work out about 4-5 times a week, only light weights, pilates, and cycling.

Good product!
I have taken this for several years as a pre workout. Works great and tastes good as well.

Gym girl juice approved
This amino complex understood the assignment. Tastes good, mixes fast, and suddenly I’m hydrated, energized, and feeling like I could add “one more set” without negotiating with myself. Definitely earned a permanent spot in my shaker.

Interfered with my sleep and tastes awful
For some reason, this really interfered with my sleep! I would sleep for two hours, wake up and then couldn’t go back to sleep the rest of the night. And, the Lemon flavor is AWFUL! This is my first time taking amino acids, so I have nothing to compare this against. But I stopped taking it and I returned to no issues with my sleep again!

Flavor is a problem
The flavor ……it’s tough. It’s like drinking a sweet TART. Emphasis on tart. No better way to describe . Can’t get past the flavor to make other comments .

Amino acid sticks
This is on subscribe. It’s so good. Mixes well in liquid. Taste is great. Strong smell of lemon from packaging, smells fresh and delish. I’ve been using for several weeks and I can tell a difference. easy for travel and on the go lifestyle. 10/10 rec

Meets Expectations
I bought this to supplement my diet before and after a total knee replacement. To me, the taste is very acceptable with a "citrusy" flavor and mixes fairly well with water or orange juice. Performance-wise, I've maintained strength and muscle volume post surgery which were my main goals.

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!

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.

Amazing Taste! I love it! love the quality of the product!

Very bad product. Obviously it wasn’t stored correctly and humidity got into it making the powder rock solid and unusable.
