Customers find this amino acid supplement to be of high quality and effective for muscle recovery, noting improved muscle recovery and increased strength. The product provides plenty of energy and helps reduce muscle soreness, with one customer specifically mentioning it prevents protein catabolism during prolonged exercise. However, the taste receives mixed feedback, with some finding the flavor good while others say it's too sweet, and the amino acid content is also mixed, with some finding it too strong. Moreover, several customers report stomach issues, including nausea and diarrhea, and find the product not worth the price.

Decent Product, Poor Quality

- Reviewed in the United States on June 13, 2021Flavor Name: BerrySize: 30 Servings (Pack of 1)Verified PurchaseI’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.

- Reviewed in the United States on February 28, 2025Flavor Name: BerrySize: 30 Servings (Pack of 1)Verified PurchaseThese taste so good! I love Thorne they have the cleanest ingredients and are third party tested. Mixes well with water or sugar free lemonade. I wish it came with more servings but over all effective source of energy and great for recovery!
- Reviewed in the United States on April 5, 2025Flavor Name: LemonSize: 30 Servings (Pack of 1)Verified PurchaseI should have truly believed the people who said this stuff tastes horrible. It does. It is so bad that I have to hold my breath to take it and I don't even know if it's doing any good to my body. I stupidly combined it with Creatine and I shouldn't have done that because either this or the Creatine caused me to have HORRIBLE MUSCLE PAIN. I tend to believe that it was the Creatine though. That said, I was just told that this is an "unreturnable" item, so I am out a lot of money. Live and learn!
- Reviewed in the United States on October 25, 2022Flavor Name: BerrySize: 30 Servings (Pack of 1)Verified PurchaseInitially when I read the reviews I had my doubts about it because of the taste. Let me tell you, the taste is just fine. I have not problems with that. It is like taking the vitamin c you put in water. In the beginning I felt it was too sweet for my taste buds ( I don't consume sugar or sugary drinks). But then my husband laughs of me because he is like you enjoy drinking it because you sip it out very slowly. I don't even realized when I drink it.
You need to know that everyone taste buds are different...so everything depends the Rx pills you take in a day, the food you eat, ect...all that changes your biochemistry, as a result, some people don't have a good experience...key is to drink it with a full glass of ice water!!
- Reviewed in the United States on April 17, 2025Flavor Name: BerrySize: 30 Servings (Pack of 1)Verified PurchasePackage Arrived early - product is a great addition to my enormous line up of supplements and tastes good enough to eat directly without mixing it in drinks
- Reviewed in the United States on January 25, 2025Flavor Name: BerrySize: 30 Servings (Pack of 1)Verified PurchaseThe product has a very strong flavor with my morning fruit smoothie. Thorn is thought to be a good product that is tested but the packaging is less than desirable plastic that is probably not recycled. Glass would be a better option. I will look for other options.

5.0 out of 5 stars Pure Quality You Can Feel – Amazing Lemon Taste!
Flavor Name: LemonSize: 30 Servings (Pack of 1)Verified PurchaseI’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!
