Most amino acids exist in two mirror-image forms: an L-form, from laevo or left, and a D-form, from dextro or right. Human proteins contain almost exclusively the L-form. This product contains precisely the D-form of serine.

What enantiomers are

Two enantiomers have the same atoms in the same order, but are each other's mirror image, like a left and a right hand. They cannot be superimposed on each other. Because enzymes and receptors themselves also have a three-dimensional shape, the two forms behave differently in the body.

D-amino acids in humans

For a long time it was assumed that D-amino acids did not occur in humans and were only found in bacteria and insects. That picture has changed. D-serine was, after D-aspartate, the second D-amino acid to be described in humans, and it occurs naturally in the body.

More than 99 percent pure

Of the roughly five hundred known amino acids, twenty-two occur in human proteins. D-serine is not one of them as a building block, but is made in the body itself. This substance comes in capsules and is more than 99 percent pure, with only the cellulose capsule around it.

D Serine by Ergomax

Ergomax D-serine contains more than 99% pure dextro serine. D-serine is a naturally occurring dextro amino acid. D-serine is produced within the human body, and common in the brain. It is a unique nootropic. Athletes, students, professionals and people doing high-skilled tasks often opt for a D-serine supplement. D-serine is produced in the body.

Benefits

  • Natural dextro amino acid
  • Suitable for professionals, athletes, students and people doing high-skilled day tasks or hobbies
  • Unique nootropic
  • Functions as a neurotransmitter and as a glio transmitter
  • Does not contain gluten or soy; GMO-free
  • Suitable for vegans and vegetarians

Proteinogenic amino acid

D-Serine is the second amino acid to have been discovered (after D-aspartate). D-Serine is the D-form of serine, a proteinogenic amino acid. Most amino acids come in two enantiomers (mirror-image molecules), in an L- (laevo = left) and in a D-structure (dextro = right). Usually the two structural variants have different effects in the body. D-serine offers the specific features of the D-form.

Biological functions of D-amino acids

It was long thought that D-amino acids did not occur in humans, but only in some bacteria and insects. It was also believed that the D amino acids had no specific biological function. It is now known that D-amino acids play important biological roles throughout the body. Proper D-amino acid concentrations are therefore essential.

Parallels with the effects of glycine

D-serine is comparable in function to glycine. A glycinergic substance is a substance that modulates the body’s glycine system. D-serine is a so-called ligand, a molecule that can bind another molecule. D-serine can bind to the glycine binding site at NMDA receptors and is a so-called glio-transmitter. The effect of D-serine appears to be more biologically relevant, and generally more potent, than that of glycine.

The building blocks of the body

Amino acids are the building blocks of proteins and are therefore crucial for our body. Our body consists of about 20% proteins. Amino acids play a key role in almost all of the body’s biochemical processes, including cell metabolism, as energy metabolites, as essential nutrients and as messengers in cell communication. Of the five hundred identified amino acids, twenty-two occur in human proteins, the so-called fundamental amino acids. The body can synthesize a number of amino acids: the non-essential amino acids. The essential amino acids can only be obtained from either food or supplementation. In specific situations non-essential amino acids may become essential.

04 / What we may claim

EFSA claims for D-serine.

Framework
EU 1924/2006
EFSA register
Subject
D-serine
(dextro)

In Europe, health claims for food supplements are assessed by the EFSA. Authorised claims are listed in the official EU register.

For D-serine, that register contains nothing. This is a substance that has only existed as a supplement for a short time, so unlike older ingredients this is not a rejected application, but a substance that has not yet entered the procedure.

No authorised claims
EU register
Regulation 1924/2006

There are no EFSA-authorised claims for D-serine in the EU register.

What you read here: how much each capsule contains, how pure it is, what the difference is between the L-form and the D-form of an amino acid and how to dose it. If you want to explore the literature, search for D-serine or D-amino acids.

Framework: Regulation (EC) No 1924/2006 and Regulation (EU) No 432/2012. No health claim for D-serine is included in the EU register and there is no claim on hold for this substance either.

They are enantiomers: the same atoms in the same order, but each other's mirror image, like a left and a right hand. They cannot be superimposed on each other.

Yes, although for a long time it was thought otherwise. The assumption was that D-amino acids only occurred in bacteria and insects. D-serine was, after D-aspartate, the second D-amino acid to be described in humans and it is made in the body itself.

Three capsules twice a day with a meal, 3000 mg per day in total. Do not exceed that dosage. A jar of 60 capsules is therefore good for ten days.

No allergens are present, it contains no gluten or soy and the product is GMO-free. The only excipient is the cellulose capsule, so it is suitable for vegans and vegetarians.
