Jarrow FORMULAS® Vitamin D3 (cholecalciferol) is derived from cod liver oil and sheep’s wool and is free of vitamin A. Vitamin D3 is converted by the kidneys into the hormone calcitriol, the active form of vitamin D3, which affects a variety of target tissues, including bone, intestine, muscle, brain, skin and immune cells.* Calcitriol enhances calcium and phosphorous absorption and stimulates the synthesis of osteocalcin, an important structural protein in bone.* Also, calcitriol is involved in proper cell differentiation (changing of cell function), including in prostate cells.*

Vitamin D May Extend LifespanVitamin D May Extend LifespanThe case for higher vitamin D levels is strongest for preventing heart disease, cancer, respiratory infections, tuberculosis, falls and fractures, and multiple sclerosisHaving enough vitamin D on board is essential for preventing disease and maintaining health, but the optimal blood level of vitamin D to ensure these benefits remains controversial. Preliminary research published in the European Journal of Clinical Nutrition estimates that by doubling current recommended vitamin D levels across the globe, more people would avoid disease and an early death, and people might extend their lifespans.
Higher levels, lower risk of death
Certain experts have questioned whether the current recommended blood levels and daily amounts of vitamin D are enough to best prevent disease and support health. This study looked at vitamin D levels across many countries and reviewed studies on the topic to explore whether higher blood levels of vitamin D, specifically 25-hydroxyvitamin D, were associated with a decreased incidence of death from common diseases such as heart disease, cancer, and respiratory infections.
Specifically, in this study, researchers reviewed the current scientific data on vitamin D to estimate whether higher blood levels of 25-hydroxyvitamin D (doubled from 54 nmol/L to 110 nmol/L) would reduce the death rate in the six global regions where vitamin D-sensitive diseases are prevalent.
- If recommended 25-hydroxyvitamin D levels were raised from 54 nmol/L to 110 nmol/L, the study authors estimate that death rates from any cause would be reduced, ranging from 7.6% for African women to 17.3% for European women, and they estimate reductions for men would be 0.6% lower than for women. The study authors speculate that such an increase in blood levels might increase life expectancy by as much as two years.
- The researchers conclude that the case for higher vitamin D levels is strongest for the prevention of heart disease, cancer, respiratory infections, tuberculosis, falls and fractures, and multiple sclerosis. The evidence is moderate for prevention of type 2 diabetes, sepsis (severe infections), and pre-eclampsia (when a woman develops high blood pressure during her pregnancy).
The study authors comment, "Increasing . . . D levels is the most cost-effective way to reduce global mortality rates, as the cost of vitamin D is very low and there are few adverse effects from oral intake and/or frequent moderate UVB (ultraviolet-B) irradiance with sufficient body surface area exposed." As the conclusions from this study are based primarily on preliminary research (that is, observational studies rather than randomized controlled trials), further research is needed to support these findings.
Tips and facts about vitamin D
- Talk with a doctor. Talk with a knowledgeable doctor about the benefits of checking your vitamin D levels; the daily amount that is recommended for you; and the risks and benefits of taking a vitamin D supplement.
- Consider sources for vitamin D. Vitamin D is obtained through: food and beverages such as fortified cereal and milk and fatty fish, such as salmon; sun exposure; or dietary supplements.
- Strive for a healthy life. It's important to realize that there isn't one magic pill or supplement that will ensure good health or a long life and that getting enough daily D is just one aspect of living a healthy life. A healthy life depends on a variety of consistent activities such as eating a balanced diet, getting enough of many types of vitamins and minerals, exercising daily, reducing exposure to environmental toxins, and reducing stress.
