Choline and non-essential (vit) amines
Published: April 06, 2018
The word "vitamin" has its origins in "vital amines" the term used to describe the molecules that are vital or essential for the functioning of your body.
These essential nutrients while necessary for optimum body function, are not synthesised by your body, and must be obtained from the food you eat.
In general, amines are organic, nitrogen containing compounds closely related to amino acids, the building blocks of proteins, and ammonia.
There are many different amines in nature and several have been found to be associated with various body functions.
In addition to vitamins, there are several amines associated with your body functions that can be synthesised in your body either from scratch or from other compounds such as amino acids and glucose and are not considered essential.
However, because the synthesis of some amines depends on the availability of other essential compounds these amines may be considered conditionally essential or conditionally indispensable amines.
These amines appear to have important biological and physiological roles in your body, and while research continues to determine the essentiality of certain amines, currently the amines considered in this article: choline, inositol, glutathione, carnitine, creatine, carnosine, and glucosamine are not considered essential nutrients.
Despite the non-essentiality of these amines, they can be obtained in supplement form and may be added to multi-vitamin products.
However, research is limited and in general does not support the claims made for the majority of non-essential amine supplements...click here to follow the link to the full article.
