Not long ago, vitamin D was thought to have a singular function, to help maintain serum calcium levels by facilitating intestinal calcium absorption and helping to regulate renal excretion and bone remodeling. Modest amounts of vitamin D were known to be adequate to help prevent low calcium levels and bone loss. Today, not only are adequate levels of vitamin D intake for optimum bone health being revised sharply upward, but newly identified roles for vitamin D have been discovered, indicating far wider health effects from this essential nutrient.*
Tissues possessing vitamin D receptors and/or expressing the enzyme for local activation of vitamin D include the immune system, skin, pancreas, prostate, colon, adrenal glands, brain, and others. Vitamin D appears to influence cellular differentiation and proliferation, immune system activity, insulin function, blood pressure levels already in the normal range, and other body processes in ways never before imagined.* Recent research is exploring the clinical implications of these new discoveries. The safety of high vitamin D intake has also been re-examined, with upper levels now set at a minimum of 2000 IU per day, and perhaps much higher. Karuna's D-1000 supplies highly-bioavailable vitamin D3 in a convenient amount for generous supplementation.
