Hi all,
Dr D's supplements have an inactive ingredient in them called L leucine ......does any one know what this is?  NAP supplements used to have magnesium strerate in them but now this l leucine is being used instead.

Magnesium stearate was added for better flow and to prevent heat build up in packing.

leucine is an essential amino acid. Foods that are high in leucine include red meat, almonds, cashews, eggs, fish, chicken, soy, and lentils.

There are several ingredients that are added to the supplements to increase bulk and make it easier to pack the capsule and make sure that ingredients are evenly distributed.

The L-form is the isomer found in living organisms.

I know of no adverse effects from ingesting small quantities of L-leucine. Leucine is utilized in the liver, adipose tissue, and muscle tissue.

It is frequently intentionally added to muscle building formulas.

If you consume really large amounts it can lead to ammonia accumulation in tissue with adverse side effects.

There are people with allergies to leucine containing supplements.

THANK YOU C Sharp and Lola for your replies.
Lola I did call NAP customer service and asked what L Leucine is and they said it was a bacteria.
I questioned this answer and so asked the forum.

Quoted from Beth

I think they must have mean their leucine was derived from a bacterial source.

Since leucine is an amino acid you can use about any source or protein and extract leucine from it. Some proteins have a higher percentage of leucine than others, so might be better sources.

A lot of time with supplement manufactures get there leucine by using bacteria to ferment a carbohydrate. The bacteria synthesize leucine and other amino acids to make protein. Leucine is then extracted from this to put in supplements.




Basic chemsitry:

Proteins are formed by combining 20 amino acids in various sequences.

   Alanine
   Arginine
   Asparagine
   Aspartic acid
   Cysteine
   Glutamic acid
   Glutamine
   Glycine
   Histidine
   Isoleucine
   Leucine
   Lysine
   Methionine
   Phenylalanine
   Proline
   Serine
   Threonine
   Tryptophan
   Tyrosine
   Valine

10 of these amino acids humans can synthesize. 10 of these amino acids humans need to get from other sources (These are called essential).  Leucine is an essential amino acid.

Formula is:

HO2CCH(NH2)CH2CH(CH3)2

Dr D
To create a product that is safe and Right For All Types, leucine, an amino acid derived from vegetable sources, is used in manufacturing D’Adamo Personalized Nutrition products. Leucine is not produced by the human body, but is essential for important metabolic functions such as building protein. There are many companies who have transitioned from using stearates to leucine, however many forms of leucine are derived from human hair or duck feathers. A few companies, including D’Adamo Personalized Nutrition, are obtaining leucine from vegetable sources which involves farming microbial leucine. This process, conducted in Germany, is time consuming and expensive, however, we believe the microbially derived leucine is of superior quality and ultimately, better for the health of our discriminating consumer.  

As always, we strive to provide the very highest quality supplements made with the safest, most effective ingredients.
