Adequate calcium and vitamin D throughout life, along with physical activity, may reduce the risk of osteoporosis in later life.
A healthful diet rich in green vegetables, beans and seeds plus strength-building exercise forms the foundation for healthy bones. Osteo-Biotect was designed to complement these healthy behaviors with essential bone-supportive micronutrients. Each capsule supplies 250 IU vegan vitamin D3 and 200 mg calcium, so 1-3 capsules can be used, depending on each person’s individual requirements. Adequate calcium and vitamin D throughout life, along with physical activity, may reduce the risk of osteoporosis in later life.
Calcium and magnesium are structural components of bone
The minerals calcium and magnesium are important for providing structure to bone tissue. Most (over 99 percent) of the body’s calcium and more than half of the body’s magnesium is stored in the bones and teeth. Calcium and phosphorus are part of the major structural molecule (hydroxyapatite) that makes up bone, and magnesium is present on the surface of that molecule. Calcium and magnesium are found in abundance in whole plant foods, however a small amount of supplementation may be appropriate, especially for some women, since calcium absorption decreases after menopause and some women may have a smaller appetite for greens.
Both Vitamin K1 and Vitamin K2 are involved in chemical reactions that control bone formation. Vitamin K in general promotes bone health via interactions with calcium, but it has been noted that K2 is particularly effective, not only for protection against bone loss , but also to protect the cardiovascular system from calcification. Clinical trials have shown benefits for bone density and bone strength in women taking K2 supplements. Vitamin K1 is plentiful in leafy greens, but vitamin K2 is difficult to get on a vegan or near-vegan diet.The dose of K2 in Osteo-Biotect complements the Vitamin K1 containing foods you eat to assure optimal K2 intake without providing excess.
Vitamin D, calcium and bone health
Vitamin D is a fat-soluble vitamin that is made in the skin after exposure to ultraviolet (UV) rays from the sun. Vitamin D functions as a hormone because it sends a message to the intestines to increase the absorption of calcium and phosphorus. By promoting calcium absorption, vitamin D helps to form and maintain strong bones; when we get sufficient vitamin D, the body is able to absorb calcium efficiently.
Vitamin D also works in concert with a number of other vitamins, minerals, and hormones to promote bone mineralization. Research also suggests that vitamin D is important to maintain healthy immune and cardiovascular systems and regulate cell growth.
As people age, maintaining adequate vitamin D and bone mass becomes a significant concern, since the skin cannot synthesize vitamin D as efficiently and the reduction in estrogen after menopause causes an acceleration of bone breakdown and calcium loss in women.
My Women’s Daily Formula + D3 multivitamin contains 2000 IU vitamin D3; in the newest formulation of Osteo-Biotect, I have reduced the vitamin D so that those women taking Women’s Daily Formula +D3 (who also have adequate blood vitamin D) will be able to receive the bone-building nutrients in Osteo-Biotect plus enough – but not too much – vitamin D. Recent research has suggested that 25(OH)D levels above the optimal range of 30-50 ng/ml do not provide additional benefit and could even be detrimental to health.
How much calcium should I take?
Calcium-rich greens, beans and seeds are staples of my dietary recommendations. Since menopause is accompanied by increased calcium loss, my Women’s Daily Formula + D3 multivitamin supplies 200 mg calcium as insurance for adequate intake (Men’s Daily Formula does not contain calcium, and Gentle Care Formula and Gentle Prenatal each contain 100 mg). However, as with most micronutrients, the vast majority of the calcium in one’s diet should be provided by plant foods, not supplements.
Many women are advised to take high-dose (1000 mg or more) calcium supplements to maintain bone health. For many years, I have recommended a lower-than-typical dose of supplemental calcium (below 500-600 mg/day), because calcium is plentiful in natural foods and because high-dose calcium supplements are not superior to lower doses for bone health and have been linked to increased risk of heart attack.
There is evidence that a lower level of calcium supplementation (when combined with vitamin D) is more beneficial for bone health than high doses. Furthermore, calcium intake is only associated with bone density when vitamin D levels are insufficient. This information suggests that when we get enough vitamin D, a high dose of calcium is not necessary.
Strong evidence has suggested that high-dose (1000 mg or more) calcium supplements increase the risk of heart attack and death from all causes. In one notable study, high calcium intake from supplements was associated with a much greater risk of death than high calcium intake from foods.
In light of this research, scientists now think the body handles supplemental calcium and food calcium differently, mostly because of the large calcium load available at one time from the supplement. Supplements cause a rapid elevation in blood calcium whereas food calcium does not; this could cause increased vascular calcification and also cause the blood to clot more easily. This may lead to the cardiovascular dangers associated with high calcium intake.
My most recent formulation of Osteo-Biotect contains a smaller dose of calcium than conventional supplements, 200 mg per capsule, to add just enough to food-derived calcium. Women can take 1-3 capsules each day depending on their calcium needs, and by splitting the dose throughout the day, it assures adequate calcium without spiking blood calcium levels. The calcium and some of the magnesium in Osteo-Biotect is provided in the form of certified organic whole powdered seaweed, harvested off the west coast of Ireland and northwest coast of Iceland.
