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.

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.

Clean & quality but taste, meh
I’ve ordered this product twice now. I do a wide array of workouts from weights to running to multi-functional. I’ve taken aminos from different companies for a long time but started to finally really research & felt much safer taking Thorne. The flavor isn’t the best if you add too much water. I’ve always added around 20oz to my intra-workout aminos with no problem but this one will get watered down. I adjusted and it’s been good. I’m also used to awful tasting soups and just powering through worse and this flavor is better than stuff I took up till the last few years. Newer people to using supplements might not like the flavor at all but trust me all workout supplements used to be awful. My recovery & muscle growth/lift gains have remained the same to the other products I’ve used with more mystery ingredients so there was no drop off there. I’m okay with taking a step back on taste and variety rather than putting mystery crap in my body from lesser regulated big companies. Product quality wins this for me & I’ve heard from multiple non-Thorne associated experts that vouched for Thrones testing.

Label Confirms it Can Expose Me to Chemicals, Including Lead - Won't Buy Again
I am sorry to be critical, I wanted to like this, but I would not recommend this product. The Amazon sales page description is deceiving. It does not mention that there is a warning on the label that this product can expose me to chemicals, including lead, which are known in the state of California to cause birth defects or other reproductive harm. I only found out about this after I had received the product. From now on, I will buy other Amino products that do not have these chemicals. If I have a choice, and I do, I will not expose myself to nutritional products that have this warning label.

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 .

Clean, Effective Amino Blend For Recovery and Energy
I’ve been incorporating THORNE Amino Complex – Lemon Flavor into my fitness routine, and it’s proven to be a valuable addition. This supplement offers a comprehensive blend of Essential Amino Acids (EAAs) and Branched-Chain Amino Acids (BCAAs), which are crucial for muscle repair and energy production. Pros: • Clinically-Validated Formula: The amino acid profile is backed by over 25 years of scientific research, ensuring efficacy in promoting lean muscle mass and enhancing energy levels. • NSF Certified for Sport: This certification guarantees that the product is free from over 200 substances banned by major athletic organizations, making it a trustworthy choice for athletes. • Clean Ingredients: The formula is free from gluten, dairy, soy, and artificial additives, aligning with clean eating principles. • Taste and Mixability: The natural lemon flavor is refreshing without being overly sweet, and the powder dissolves easily in water, making it convenient for pre or post-workout consumption. Cons: • Price Point: At around $49 for 30 servings, it may be on the higher end compared to other amino acid supplements. However, the quality and NSF certification may justify the cost for those seeking a premium product. Bottom Line: THORNE Amino Complex – Lemon Flavor stands out for its clean formulation and scientifically-backed amino acid profile. It’s an excellent choice for individuals looking to support muscle recovery, enhance energy production, and maintain lean muscle mass, especially for those adhering to strict dietary standards or competitive athletes requiring NSF-certified products. #ThorneAminoComplex #EAAs #BCAAs #NSFCertified #MuscleRecovery #CleanSupplements #WorkoutNutrition #GlutenFree #DairyFree #SoyFree #LemonFlavor

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.

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