L-Alanine

Alanine (like glutamine) is one of the most important amino acids needed for circulating energy throughout the body. It is a non-essential amino acid that is largely concentrated in muscle and only slightly concentrated in the blood, kidney, liver and brain. Alanine is made in the body from the conversion of pyruvate (compound of carbohydrate metabolism) or the breakdown of anserine and carnosine.

Function- Alanine is the primary amino acid that transports nitrogen from the muscle to the liver and therefore guards against the accumulation of toxic substances It has displayed positive effects on blood sugar (diabetes and hypoglycemia), ketone metabolism, liver function, immune enhancement and prostate health.. Alanine may also build muscle and can be converted by the liver into useable glucose and like GABA, taurine, and glycine acts as an inhibitory neurotransmitter.

Blood sugar- Alanine aids in the metabolism of glucose (blood sugar) and can be used as an energy source when needed by brain, muscle, and the central nervous system. Low levels of alanine relates linearly to the disturbances associated with low blood sugar also known as hypoglycemia. Methionine, phenylalanine, and tyrosine also show this reproducible pattern with low blood sugar. Alanine stimulates an increase in blood sugar, which triggers the release of glucagon and therefore releases glucose. Alanine deficiency should be considered if an individual has symptoms of anxiety, tremors and rapid heart rate. Research has found that for people with diabetes, taking an oral dose of L-alanine can be more effective than a conventional bedtime snack in preventing hypoglycemia at night.

Ketone metabolism- Ketones occur in the incomplete breakdown (catabolism) of fatty acids. Alanine has aniti-ketogenic properties and may help prevent ketosis and reduce triglycerides which are significant metabolism conditions in diabetics. Alanine decreases ketogenesis and inhibits the breakdown of proteins in humans by direct effect on the liver. Combined with a low refined carbohydrate diet and balanced nutritional program alanine plays a significant factor to regain control for those suffering from blood sugar disorders.

Immune system- Alanine has proved to be very important in the body’s reproduction of lymphocytes and thymus growth which are largely responsible for promoting a strong immune system.

Prostate- Alanine is present in prostate fluid, and it may play a role in supporting prostate health. There have been numerous cases shown to have benefited from support of alanine to the prostate.

Deficiency- Common conditions associated with alanine deficiency are hypoglycemia, muscle breakdown and wasting, seizures, low growth hormone levels, fatigue, elevated insulin and/or low glucagon levels.

Sources- Foods that are a source of alanine are turkey, pork, yogurt, ricotta cheese, eggs, chicken, cheese, avocado, duck, granola and wheat germ.

Precautions- In lab test very high doses of alanine was given which increased urinary excretion by a thousand fold and no side effects were recorded. Individuals with Epstein Barr virus and chronic fatigue have been shown to have excessive alanine levels and low levels of tyrosine and phenylalanine which are probably related to improper metabolism.

Requirements- There is no Recommended Dietary Allowances (RDA) listed. Individual needs may differ due to clinical conditions, biochemical individuality and absorption. All sources of nutrients should be consumed in their most natural state, in the form of a variety of foods or supplements when necessary. Free form amino acid supplements are immediately absorbed by the body and should be consumed with natural occurring cofactors for best results. Consulting with a physician that is properly trained in the natural healing sciences and amino acid therapy may be needed for optimum results.
