Criteria Used for Evaluation

Value

The value of the best essential amino acid supplement is determined by the affordability of the product per serving. If a product is low cost but yields significant serving amounts, it means you get more bang for your buck. If a product is high cost and yields small servings, it means the cost per serving is higher. So value scoring directly reflects the products cost effectiveness, helping you choose a product that will be the best for any budget.

Side Effects

When rating a products score in side effects, we took into consideration ingredients, known side effects, and common undesirable symptoms caused by consumption of the supplement. Generally, products with cleaner ingredients produce fewer if any side effects, and products with chemicals or unnatural ingredients will result in issues.

Product Purity

Product purity is essential when choosing supplements. We rated these amino acid products based on the purity of the products ingredients, additives, flavoring, and sugar content. The best essential amino acid supplements with few added or synthetic ingredients are considered to be purer, while supplements that contain a bunch of other ingredients are considered to be less pure. The closer a product is to being made up just the main ingredient, the higher the score.

Potency

The potency of a supplement is determined by the number of amino acid in each serving and the ease of use for getting one serving. If a product has a high dosage of amino acids in a single serving size, such as one scoop or one capsule, it is considered to be a more potent product. Controversially, if a product has a low potency, it might not have a high dosage of amino acids or its serving size is not easy to take to get the dosage. If a product requires users to take several capsules, or consume a large quantity of powder, for example, it is considered to have a lower potency.

Effectiveness

The effectiveness of a supplement is crucial to consider when buying products. That's why we took careful consideration when scoring products in this category. We looked at the dosage potency of a supplement and combined that with the bio-availability of the amino acids and other beneficial vitamins in that dosage, and the efficiency of the bio-availability. A product is considered to be more effective if the product is easily and quickly absorbed by the body, giving you access to fast results.
