Dr. Fuhrman’s Osteo-Sun

Dr. Fuhrman’s Osteo-Sun gives you extra vitamin D plus conservative doses of calcium, magnesium and vitamin K2 for healthy bones.*

Features:
  • 100% vegan: two capsules contain 1000 IU vegan vitamin D3
  • Contains bone supporting minerals magnesium and calcium
  • New: lower dose of calcium
  • New: Vitamin K2
  • New: Prune powder

A healthful diet rich in green vegetables, beans and seeds plus strength-building exercise forms the foundation for healthy bones. Osteo-Sun was designed to complement these healthy behaviors with essential bone-supportive micronutrients and polyphenol-rich prune powder. Each capsule supplies 500 IU vegan vitamin D3, so 1-4 capsules can be used depending on each person’s individual vitamin D requirement. Osteo-Sun was designed to be higher in vitamin D and lower in calcium compared to most other bone health supplements, and provides a small dose of calcium per capsule as insurance for adequacy.*

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.1 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, and low doses are included in Osteo-Sun as insurance for adequate intake, especially in women with smaller appetite for greens.

Vitamin K2
Vitamin K is involved in chemical reactions that control bone formation, and the dose of K2 in Osteo-Sun complements other Vitamin K containing foods and supplements to assure optimal K2 intake without providing excess.

Prune powder
Prunes are rich in several polyphenols that may promote balanced bone turnover, and preliminary studies suggest that eating whole prunes daily may be an effective strategy for preserving bone health in postmenopausal women.2-6 I have included prune powder in Osteo-Sun to supplement a healthful diet with these polyphenols.

Vitamin D insufficiency is common
It is estimated that over 70 percent of Americans have an insufficient vitamin D levels (blood 25(OH)D  below 30 ng/ml).7 My multivitamins were each designed to provide 2000 IU vitamin D each day, enough to meet the needs of most people who work indoors and have limited sun exposure. However, some individuals require more vitamin D to maintain favorable levels (30-45 ng/ml). Osteo-Sun is intended to meet the needs of those who require extra vitamin D.*

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. this means that 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. Since vitamin D receptors are present in almost every type of cell in the human body, vitamin D is likely important for overall health and well-being, and we will learn more about the benefits of vitamin D as new research emerges.8,9*

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.10,11*

Why a low dose of calcium?
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 and Gentle Prenatal each contain 100 mg). However, as will 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 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.12 Furthermore, calcium intake is only associated with bone density when vitamin D levels are insufficient.13 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.14-18 In one notable study, high calcium intake from supplements was associated with a much greater risk of death than high calcium intake from foods.14

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.*

In my most recent formulation of Osteo-Sun, I have reduced the amount of calcium in Osteo-Sun to 100 mg/day to replicate the gentle flow of food-derived calcium. Women’s Daily Formula +D3 and Osteo-Sun together provide 300 mg calcium daily, well below the range associated with harm, and by splitting the dose it assures adequate calcium without spiking blood calcium levels. The calcium and some of the magnesium in Osteo-Sun is provided in the form of certified organic whole powdered seaweed, harvested off the West coast of Ireland and Northwest coast of Iceland.

Suggested Use: 2 capsules daily.
