Are there any side effects to taking isolated amino acids? Are amino acids considered to be drugs?
Isolated proteinogenic amino acids are generally well tolerated. Side effects are generally not to be expected, even at excessively high dosages. Most of them are “Generally Recommended as Safe” (GRAS) and therefore they are usually nutritional supplements and NOT drugs. But exceptions apply (see L-Thyroxin, used as a drug for thyroid gland malfunctions).

Which amino acid products can be recommended?
There is no single product or brand that is best for all uses.
What is important is the right combination, as well as appropriate dosage of amino acids and vitamins for your specific goal. Therefore, we have compared product ingredients with the optimal, generally recommended blends and dosages. Of course, production should meet highest standards and the shopping experience should be safe and easy.
From the more than 400 products available in Europe, we have selected the five best and most well-known for each benefit area.
Selection criteria included not only composition, dosage, and quality of raw materials, but also manufacturers’ reliability in supply, transparency, and customer service. A positive customer service experience was a requisite to be on our list.
