Amino Acids

This category carries individual amino acid powders alongside a multi-ingredient essential amino acid blend, so the first decision is whether to use a single compound or a combination. The individual options include L-Leucine, L-Glutamine, L-Theanine, L-Citrulline Malate 2:1, L-Carnitine, and Glycine, each targeting a different purpose. Shoppers who want to support workout recovery around training tend to reach for L-Leucine or the EAA blends, while those focused on gut health and digestive wellness typically choose L-Glutamine. L-Theanine sits apart from the rest, being used more for calm focus rather than physical performance, and Glycine is noted here for its water solubility, which affects how easily it mixes into liquids.

A few products appear in more than one listing because they are offered in different sizes, so check the weight before adding to cart. The EAA blend, for instance, comes in a 2.6 lb option alongside a smaller bag, which matters if cost per serving is a consideration. Within the carnitine options, there are two distinct forms, L-Carnitine Tartrate and a straight L-Carnitine powder, and a second brand appears for the latter, so comparing purity statements and serving size between those two makes sense. The L-Citrulline is specifically the 2:1 malate ratio, a detail worth noting if a particular ratio was recommended to you.

All products in this category are unflavored powders, which means they are generally straightforward to stack or mix with other supplements. Because the powders are sold without added flavors or fillers, looking at the ingredient list for any exceptions to that is a practical step before purchasing.
