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.

Taste and Quality are Excellent!
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
Thorne has a reputation for high quality products so I thought I’d try this whey protein. It tastes really good! I find it easy to digest, and it dissolves easily. I plan to make this my go-to whey protein.

Definitely sweet but good mixed
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
The vanilla would be too sweet on it's own for me but with strawberries and spinach it's perfect.

Horribly ‘weird’ sweet flavor
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
Horrible taste - synthetic sweetness than destroys my shakes. I bought Thorne because of its high quality but this is one of their products that won’t work for me. I’m struggling through the jar because it’s too expensive to waste. Using cacao powder, cinnamon & cardamom to try to tone down the overwhelming ‘sweet.’
