Calcium & Vitamin D for Healthy Strong Bones
By Prasad Adavikolanu
In all over world millions of people are having bone related problems and this bone related problems generally found on people aged over 50 years.
Calcium is Good
For most people, calcium salts are absorbed about the same, between 30% and 40% of the administered dose. People who have low stomach acid (hypochlorhydria) should not use calcium carbonate, because that form of calcium is absorbed poorly in the absence of stomach acid. Calcium phosphate may be preferable for many older people, because phosphorus is necessary for normal bone formation, the phosphorus intake of older people is often low, and calcium supplements inhibit the absorption of phosphorus. Also, calcium bound to phosphorus is the form in which calcium in the bone is stored, and it has a much greater bone activity than other forms.
Vitamin D for Strong Bones
Because vitamin D is produced when ultraviolet rays from the sun hit skin, people who stay out of the sun, wear sunscreen, or live in a northern latitude (such as Boston or Seattle) where less ultraviolet light reaches the skin, are at increased risk of vitamin D deficiency. In addition, aging decreases a person’s ability to synthesize vitamin D in the skin. Results from five research trials on vitamin D found that supplementation with 700-800 IU of vitamin D per day decreased the number of hip fractures by 26%, but 400 IU per day was ineffective. In addition to enhancing bone health, vitamin D improves nerve and muscle function in older people, thereby reducing their chances of falling down. supplementation of elderly women with 800 IU of vitamin D per day has been shown to decrease the number of falls by about 50%.
Vitamin D Safe
The Food and Nutrition Board of the Institute of Medicine established a “safe upper limit” of 2,000 IU per day in 1997. More recent research suggests that up to 4,000 IU of vitamin D per day is safe for the average person.11 However, you likely don’t need nearly this much to address most bone issues.
Nutrients Besides Calcium and Vitamin D
Bone is living tissue, constantly remodeling itself and engaging in numerous biological functions. Like other tissues in the body, bone has a wide range of nutritional needs. The typical refined and processed American diet has been depleted of many different vitamins and minerals, some of which play a key role in promoting bone health. Not getting enough of one or more of these micronutrients may be an important contributing factor to the modern epidemic of osteoporosis. In addition, supplementing with calcium may cause a loss of magnesium, zinc, silicon, manganese, and phosphorus, unless these nutrients are also provided.
