Recently, I've been trying out different flavors and ingredients of EAA supplements, and the top-ranked products really do have noticeable differences. Myprotein's version focuses on ingredients, with a high essential amino acid content of 79.6%, but it has a bitter aftertaste, so you'd need to be prepared if you drink it every day. On the other hand, the fresh kiwi-flavored EAA can be chugged like juice, but the essential amino acid content drops to 65.7%. If you're cost-conscious, the large-volume version of Different costs about 55 yen per serving and seems to have decent ingredients. Ultimately, whether you choose based on ingredients or taste affects the rankings. There are also options with β-alanine included, and all-in-one types with creatine, making EAA selection more complicated than I expected. The best approach is probably to choose based on your workout frequency and preferred flavor, but if you don't carefully check the ingredient list, you'll end up regretting it.
