Amino acids are organic compounds, which are required in virtually all biological processes. They are key structural components of all the tissues in the body. For example amino acids provide cellular structure and perform essential functions in our bodies. They are also involved in the storage and transport for nutrients, vital for assisting with healing and repairing of tissue, and critically support our metabolism as a whole.
Although the body can produce many amino acids, it cannot synthesise these eight amino acids and they must be sourced from diet. They include: Phenylalanine, the three Branched Chain Amino Acids Valine, Leucine and Isoleucine, Lysine, Threonine, Tryptophan, and finally Methionine.
Therefore it is no surprise that many supplements are sold on the market to support up your hair, skin, blood, muscles and organs. In this article we take a look at what are the most popular amino acids that people are intersted in based on search analytics.
From the overall graph above the article the first observation it that the interest is constant, the relative popularity of each supplement versus another changes little over a 10 year period despite a lot of research and release of new information in that period. An indication that perceptions and beliefs are hard to change or possibly the situation is that research simply has not discovered ground breaking findings.
In the zoomed in graph below you find the most searched for supplements. As you can see those are Taurine, Arginine, Glutamine, Lysine, Glycine and 5-HTP:
Surprisingly it includes only one of the essential amino acids, Lysine, and 5 non amino acids. Are we seeing here collective wisdom at play or is this the strength of perception and commercial media. At least the author of this article has become curious enough to investigate what health benefits are expected from these amino acids and will post the views that in next articles starting with Taurine that shows are dramatic rise in interest in the last months.
