Special Issue Information
Dear Colleagues,
We present a Special Issue of Nutrients on the “Relevance and Safe Utilization of Amino Acids in Dietary Supplements”.
Amino acid supplementation may be recommended in healthy individuals who present with a deficiency of one or more amino acids in the dietary proteins that humans consume. Clinical and experimental studies also focus on specific physiological and pathophysiological situations where the requirement for specific amino acids increases, such as attaining optimal metabolic and physiological functions.
However, there is a major concern regarding supplements with amino acid contents above the tolerable upper intake level (UL), defined as the highest level of daily amino acid intake that is likely to pose no adverse effects on consumer health.
Based on this context, we invite contributions to this Nutrients SI which will gather original reports from clinical trials aimed at documenting the efficiency of supplementation with specific amino acids in different situations, as well as the doses of specific amino acids which must not be exceeded in supplements for user safety. Original reports from experimental studies deciphering the mechanisms involved and the effects of amino acid supplements are also welcome. Contributors are encouraged to submit review papers dedicated to these topics.
I look forward to receiving your contribution.
Dr. François Blachier
Guest Editor
