  • Clean & quality but taste, meh
Flavor Name: Berry Size: 30 Servings (8.0 Ounce) (Pack of 1)
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. ... show more

  • Great tasting and works
Flavor Name: Berry Size: 30 Servings (8.0 Ounce) (Pack of 1)
Thorne is our favorite blend of supplements. This amino acid complex is a tad expensive but you get what you pay for. Noticed a difference in energy levels immediately. Great value. No noticeable negative side effects

  • Seemed okay but tough taste
Flavor Name: Berry Size: 30 Servings (8.0 Ounce) (Pack of 1)
I didn’t use enough an consistently to see if it made a difference… but the taste isn’t very good… which I guess impacts all of these kinds of products.

  • Horrible!!!
Flavor Name: Berry Size: 8.15 Ounce (Pack of 1)
I should’ve listened to other reviewers. This is absolutely undrinkable. The taste is horrendous. I have tried mixing it with double the amount of water - undrinkable. I have tried making gelatin with it - inedible. Tried mixing small pieces of the gelatin I made into hot hibiscus tea to mask it - barely tolerable. Sweetness is off the charts. ... show more

  • pricey but worth it
Flavor Name: Berry Size: 30 Servings (8.0 Ounce) (Pack of 1)
Over 60 years old, working out with heavy (well heavy for me) weights, you need help with recovery, and I did my research, and this was highly recommended. It is prices but reducing recovery time and helping me keep up with my son is worth it.

  • Tastes like a supplement should
Flavor Name: Berry Size: 30 Servings (8.0 Ounce) (Pack of 1)
This is subtly sweet and mildly tart…it’s just right! Too many people require supplements to be ridiculously sweet! They need to go off sugar for 4 weeks and reset their tastebuds… not everything needs to taste like a candy bar. This aminos powder is a supplement and it tastes like one. It dissolves beautifully in water. ... show more

  • Great formula, but desperate for an unflavored option
Flavor Name: Berry Size: 30 Servings (8.0 Ounce) (Pack of 1)
I’ve been incorporating Thorne’s Amino Complex into my daily stack, and from a nutritional standpoint, it’s hard to beat. The clinical dosing of essential amino acids is exactly what I’m looking for to support my recovery and fitness goals. Thorne is usually my go-to for purity and quality, and this product is no exception when it comes to the actual ingredients. However, the flavor profile is a significant drawback. To be blunt: the flavors are just not good. They feel chemically and overly sweet, which makes it a chore to drink rather than a supplement I look forward to. I would much prefer an unflavored and unsweetened version. Having the option to just mix the raw powders into water or my own beverage without the unnecessary flavorings and sweeteners would be a game-changer. If you’re sensitive to artificial tastes or just prefer a "cleaner" experience, the current options might be a struggle. Pros: High-quality amino acid profile. Trusted brand with great sourcing. Cons: Flavors are unpleasant and too sweet. No "naked" or unflavored option available. ... show more
