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, 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

Terrible Flavor
I am sure the product is good but I could not drink it because of the flavor! It took everything in me to get this drink down. Will not buy again. Flavor is terrible!

Good taste/dissolves well
Our family loves this product, it dissolves easily, tastes great and the plus is the kids like it. It’s a great alternative to sports drinks with the trash in them.

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.

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!

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.
