D-1000 by Karuna is a highly-bioavailable vitamin D3 (Cholecalciferol) in a convenient amount for generous supplementation.

Cholecalciferol (vitamin D3) is the form of vitamin D that appears to be more bioavailable, more easily converted and better able to bind than ergocalciferol (vitamin D2).

Further study into this essential nutrient is showing its potential for more than just bone health and calcium absorption. The adrenal glands, brain, colon, immune system, pancreas, prostate and skin are a few of the examples of tissues that possess vitamin D receptors or that express the enzyme for its activation.

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.
