Helps Reduce Signs Of Aging
Vitamin C also plays an essential role in the formation of collagen, which is a fibrous protein that helps form connective tissue in the skin.
As the skin ages, collagen production decreases. This is what causes the skin to lose elasticity, and sag. While skin aging is inevitable, daily use of vitamin C can help boost collagen production and slow down the aging process. This boost in collagen helps firm up the skin and reduce the appearance of fine lines and wrinkles.
To reduce signs of aging, it is particularly important to use a topical serum so that the vitamin C can reach the skin cells directly.

Can Vitamin C Help With A Cold
Ascorbate is also a potent virucide that can destroy many viruses including the cold virus. This is only possible at relatively high doses, and not at vitamin levels.
Back in 1970, the book Vitamin C the Common Cold and the Flu was published. The author was Linus Pauling, who is the only individual awarded two un-shared Nobel prizes in the world and probably the most important biochemist of the 20th century.
it is especially important that everyone know that he can protect himself to a considerable extent against the disease and its consequences by the use of this important nutrient, vitamin C – Linus Pauling, Nobel Prize
Paulings book became a national bestseller, and many people credit Paulings book for the decline in mortality rate of heart disease after it was published. .
Heres something interesting, why do animals never get a cold?
Animals dont suffer from colds because they make their own ascorbate in the body continuously. They have this advantage over us. We cant produce our own so we must relay on external sources.
Our challenge is that we must provide our bodies with a continuous supply of vitamin C if we want the same health benefits that animals naturally get, since most of them produce their own vitamin C in the liver.

Cysteine And Gsh Concentrations
For analysis of total cysteine and GSH , 100200 mg of frozen tissue was pulverized with a mortar and pestle sitting on dry ice. The powdered tissue was weighed and added to 1 mL of 1 mol/L perchloric acid containing 1 mmol/L bathophenanthroline disulfonate and 1 mmol/L bathocuproine disulfonate. The sample mixture was sonicated with two 20-s bursts separated by a cooling period, and the sonicated mixture was frozen at 70°C. For further analysis, samples were thawed and centrifuged at 15,000 × g for 10 min to obtain the acid extract. As an internal standard, -glutamylglutatmate was added to the acid supernatant to yield a final concentration of 0.5 mmol/L. The sample/internal standard mixture was then derivatized as described by Fariss and Reed . The 2,4-dinitrophenyl derivatives of acidic amino acids, including those of the derivatized thiols , were separated by reversed-phase ion-exchange HPLC and quantified as described previously .

Biotin belongs to the group of B-Vitamins. The vitamin is an organic compound that can be found in all cells of the human body. Biotin works together with the other vitamins in the B-group.
Biotin plays an important role in energy metabolism. It breaks down fat, protein and carbohydrates to create glucose. Thereby it enables the uptake of glucose by body cells, which will be transported for energy all around the body.
It is also needed to absorb vitamin C from our intestines and helps to maintain nervous cells, which are needed to signal from our brain to our body.
Biotin also helps skin cells to renew and repair.
The same counts for hair and nails, biotin makes sure our hair and nails stay strong.
Main functions of Biotin in the body
- Energy metabolism: Break down of macro nutrients .
- Assistance in renewal/reparation of skin, hair and nail cells.
- Maintenance of nervous system
