Jarrow Formulas

  • Good for bone and calcium metabolism.
  • Promotes healthy cell replication.
  • Provides protection for breast, colon, and prostate function.

Jarrow Formulas® Vitamin D3 (cholecalciferol) is taken from sheep’s wool and cod liver oil, and is produced without Vitamin A. Vitamin D3 is fat-soluble. Kidneys convert vitamin D3 into calcitriol, which is the form of Vitamin D3, which is used by the body. This activated form greatly affects numerous tissues, e.g., bone, muscle, skin, intestine, and the cells involved in the immune system. The absorption of phosphorus and counts is enhanced by calcitriol. Calcitriol also triggers the synthesis of osteocalcin, which is a necessary structural protein in bones. Calcitriol is involved in the changing of the function of cells (proper cell differentiation), including prostate cells.

Suggested Use: As a dietary supplement, adults take one (1) softgel daily, or as directed by a health care professional. Store in a cool, dry place and away from direct light.

Vitamin D (as cholecalciferol) 1000 iu   250%

Notes: 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.*

Other Ingredients: Gelatin, glycerin, water (capsule), rice bran oil. The role of Vitamin D in helping to maintain bone density and strength is clear. It is required for the process of moving calcium through the intestinal wall into the bloodstream.† Even though the human body can manufacture Vitamin D under ideal circumstances, there is strong evidence that much of the American population suffers from a deficiency of the nutrient. This means that supplementation may be important. Two forms of Vitamin D are commonly found in supplements; D-3 (cholecalciferol) and D-2 (ergocalciferol). Vitamin D-3 is more bioactive.

Contains No Added: sugar, salt, dairy, gluten, yeast, wheat, corn, soy, preservatives, artificial colors or flavors.

Caution: DO NOT take more than 1 softgel per day without medical supervision. Consult your physician if undergoing dialysis or if you have any kidney disfunction, including stones. Keep out of the reach of children.
