Vitamins D and K: the most under-rated Vitamins for our health.
• Vitamin D—a group of fat soluble compounds. Activation requires ultraviolet light. Vitamin D is necessary for calcium utilization in bone formation. It increases muscle strength in the elderly. It helps prevent insulin resistance, autoimmune diseases, obesity and certain cancers, such as cancer of the colon and lung cancer. It has been found to reduce incidence of multiple sclerosis, osteoporosis and depression as well. Fifty percent of Americans are deficient in Vitamin D, and in one study low Vitamin D levels are associated with earlier death than those with adequate vitamin D levels. Vitamin D is found in fatty fish, such as tuna and salmon, and in egg yolks. Exposure to sunlight increases our vitamin D, but most people try to avoid excess sun exposure to reduce the incidence of skin cancers. We are therefore between the proverbial rock and a hard place. We want the Vitamin D, but not the skin cancers. Again—moderation. Have your doctor check your blood levels of Vitamin D, and take supplements if they are low. 1000 to 2500 IU per day may be necessary to reach the ideal levels which are above 30ng/ml. Generally, supplements are necessary, because even moderate sun exposure will not get us the adequate levels required for our best health.
• Vitamin K—is called the anti-hemorrhagic vitamin and is essential for formation of blood clots. It is probably the most under-rated vitamin because it also mobilizes calcium
from arteries back into bone where it belongs, thus reducing arteriosclerosis, heart disease and osteoporoses, thus, Vitamin K strengthens bones. Vitamin K is another anti-cancer vitamin and helps prevent cancer of the breast, colon, liver and stomach and reduces inflammation. Vitamin K2 is longer acting than Vitamin K1, and is more effective in reducing atherosclerosis of the arteries.
