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.

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.

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

The taste is horrible
Taste is horrible. I tired to get past it. Saw other reviews and thought “they are being over critical”. No, that taste just was not for me. No refunds. Which I get. I rolled the dice and I lost on this one.

Clean, reliable support
Thorne’s Amino Complex is a high-quality supplement that delivers clean, reliable support for energy, muscle recovery, and overall performance. The blend mixes smoothly, tastes refreshingly light, and gives a steady boost without any heaviness or crash. It’s the kind of product you can feel good about using—pure, thoughtfully formulated, and consistent from day to day. My only wish is that it offered a higher amount of protein per serving. With just a bit more, it would be an even stronger partner for active days and post-workout recovery. Even so, Thorne continues to impress with its commitment to excellence. This is a dependable amino formula that does its job with integrity and ease.

Buy it
I've purchase three different EAAs in a month. This one includes all 9 EAAs, dissolves well, and tastes pretty decent. Highly recommend if you are looking for EAAs only.

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
