Terrible taste, great brand
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
Thorne is a phenomenal company and the only supplements I trust. The reason I rated this so low is the absolutely disgusting flavor. Do yourself a favor and try another option

Flavor is a problem
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
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 .

Great for recovery
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
Really helps with post work out recovery. I feel noticeably less sore when I take this after a workout. Definitely prefer the lemon flavor over the berry.

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.
