Glutamine is the most abundant naturally occurring, non-essential amino acid in the human body. Also known as L-glutamine, this amino acid is used by our human bodies to create proteins, so-called sugars, and to enable the production of the super antioxidant glutathione.
Glutathione is a tripeptide and made up of three amino acids:
2. Glutamic Acid
Vitamin C and Glutathione have a unique relationship. Both Glutathione and Vitamin E are boosted by Vitamin C. Vitamin C reduces glutathione back to the active form. In its active form, glutathione will regenerate Vitamin C from its oxidized state.
Glutathione helps determine the balance of pigments pheomelanin and eumelanin in our skin.
Of recent important discoveries made by scientist, is the link between Vitamin C and glutathione levels and how pheomelanin and eumelanin depend on glutathione, L-cysteine and the TYRP1 enzyme for balance.
L-Glutamine and Benefits to the skin.
- L- Glutamine has been scientifically proven to play an important role in the growth of fibroblast cells.
- Increases collagen production
- Antioxidant – helps neutralise harmful toxins and free radicals
- Helps to firm the skin through its ability to regulate the balance of acid base levels.
- Helps your immune system function properly
- Keeps proteins active and through this ensures the correct execution of metabolic processes.
Glutamine has been shown to have positive effects on Human Growth Hormone maintenance, immune system function, cell volume, and protein substrate recycling for increased protein synthesis.
L-glutamine prevents muscle catabolism and improves your body’s ability to recover during sleep. It also provides energy for the digestive cells and aids these cells in regeneration and renewal therefore influencing the absorption ability of the intestine. It is found in the nervous system as L-glutamine is very chemically similar to the neurotransmitter glutamic acid.
Autoimmune disease of the digestive system are frequently accompanied by reduced permeability of the intestinal wall, leading to poor utilisation of vitamins from food intake.
L-glutamine supplements can drastically increase intestinal permeability, which may improve the ability for vital substances entering the body.
It has also been proven that L-glutamine improves the metabolism and entire clinical state of cancer patients without increasing tumour growth.
Low levels of Glutamine are caused by stress, compromised immune system, medical conditions such as surgery, infection, injury and inflammation.
Natural sources of Glutamine can be found in almost all raw fruits and vegetables, nuts, and other protein rich sources of food including whey protein, lean meats, eggs, whole grains.
Glutathione Pills and Skin Lightening
The effectiveness of glutathione pills to lighten skin is still in its infancy stages. Some brands on the market containing glutathione are sold as skin whitening product. The benefit of use stated, is that they possess potent antioxidant ability and also inhibit tyrosinase activity.
The side effects
Although skin whitening pills are not as dangerous as they seem, there has been some cases where skin whitening pills have caused side effects.
Disruption to normal skin function – interference with normal production, potential modification to the bodies hormone levels.
Some ingredients influence the stimulation for an allergic reaction resulting in skin inflammation showing signs of swelling and skin rash.
Some ingredients may stimulate symptoms such as insomnia, nausea, vomiting, indigestion, headaches and many others.
Also known as GSSG or L-Glutathione has been studied for its effects as a topical agent for skin whitening use. In a randomized double-blinded, placebo controlled, matched pair study using two percent GSSG lotion and placebo lotion over 10 consecutive weeks with a group of 80 healthy female candidates concluded that GSSG appears to be superior to hydroquinone. Further it improved moisture levels and indicated it is a potent agent that can effectively and safely promote skin whitening and improved skin condition.
Natural food sources such as Avocado are rich in nutrients including monounsaturated fats, glutathione and vitamin E. While consuming avocados will also benefit the skin, their use topically is also highly beneficial. There are many possible ways to use avocado on the skin, either the complete fruit or the oil.
