Editor's Take
Amazon reviewers say THORNE Amino Complex is generally valued for quality, amino acid content, and workout recovery, with many noting better muscle recovery and reduced soreness. Reviews are mixed on taste, sweetness, smell, stomach comfort, and value for money, with some customers saying it tastes great and blends well while others find it too sweet or upsetting to the stomach.
Walmart reviewers give a similarly mixed picture: many praise the taste, recovery support, and day-to-day energy, but some complain the flavor is overly sweet or unpleasant and the product is expensive. Review summaries on iHerb also point to positive feedback on ingredient quality, mixability, and workout performance, alongside complaints about sweetness and pricing.
On Reddit and forums, this product appears to come up mostly in broader supplement discussions, where THORNE is often described as a trusted brand with premium quality but a high price. YouTube search results show a few real videos specifically about Thorne Amino Complex, including review and product videos, which suggests the product has some independent video coverage as well.
