The Importance of Sulfur
Close to half of the sulfur in your body can be found in your muscles, skin and bones, but it does much more than benefit just these three areas. It plays important roles in many bodily systems.
Sulfur bonds are required for proteins to maintain their shape, and these bonds determine the biological activity of the proteins. For example, as explained in the featured MSM newsletter, hair and nails consists of a tough protein called keratin, which is high in sulfur, whereas connective tissue and cartilage contain proteins with flexible sulfur bonds, giving the structure its flexibility. With age, the flexible tissues in your body tend to lose their elasticity, leading to sagging and wrinkling of skin, stiff muscles and painful joints.
A shortage of sulfur likely contributes to these age-related problems.
In addition to bonding proteins, sulfur is also required for the proper structure and biological activity of enzymes. If you don't have sufficient amounts of sulfur in your body the enzymes cannot function properly, which can cascade into a number of health problems as without biologically active enzymes, your metabolic processes cannot function properly.
Sulfur also plays an important role in:
The featured study looked at a broad scope of overlapping metabolic pathways in order to determine which ones may be affected by insufficient intake of dietary sulfur. They also evaluated the modes of action of a variety of sulfur-containing dietary supplements, including chondroitin and glucosamine, commonly used to improve joint health.
- Your body's electron transport system, as part of iron/sulfur proteins in mitochondria, the energy factories of your cells
- Vitamin-B thiamine (B1) and biotin conversion, which in turn are essential for converting carbohydrates into energy
- Synthesizing important metabolic intermediates, such as glutathione
- Proper insulin function. The insulin molecule consists of two amino acid chains connected to each other by sulfur bridges, without which the insulin cannot perform its biological activity
According to the authors:
"Sulfur amino acids contribute substantially to the maintenance and integrity of the cellular systems by influencing cellular redox state and the capacity to detoxify toxic compounds, free radicals and reactive oxygen species.
... Sulfur containing metabolites, of which glutathione is a key exponent, merge in their functioning with many other compounds that play a major role in mechanisms which are receiving tremendous interests as parts of conventional and complementary medical care. These include the n-3 and n-6 polyunsaturated fatty acids, minerals such as Selenium, Zinc, Copper and Magnesium, vitamins E and C, antioxidants such as the proanthocyanidins and lipoic acid, many of which are involved in the synthesis of prostaglandins and in the antioxidant cascade.
More and more evidence is accumulating and focusing on the cooperative role that glutathione and other sulfur metabolites play in the homeostatic control of these fundamental mechanisms."
