Vitamin D

Our vitamin D is the same form that your skin produces naturally when exposed to the sun — cholecalciferol — or “D3.” It comes in a flexible dosage of 1000 IU in the most natural and absorbable form available, so it’s easy to optimize your levels of this “sunshine vitamin.” The latest research shows that a billion people worldwide are deficient in vitamin D, young and old alike, in both northern climates as well as some of the sunniest places on earth. Low levels of vitamin D are linked to osteoporosis and muscle weakness, and life-threatening diseases like cancer, diabetes, and heart disease. Vitamin D plays a key role in limiting bone breakdown and maintaining bone-critical muscle mass so important for women in or near menopause.

How can vitamin D help you?

• Increases healthy immune function, since immune cells have vitamin D receptors, along with tissues in the brain, prostate, breast, and colon.
• Helps ensure proper absorption and metabolism of calcium, phosphorus, and other nutrients that strengthen bone. Without enough vitamin D, only 10-15% of ingested calcium may be absorbed.
• Promotes proper cell growth because vitamin D controls more than 200 genes directly or indirectly.
• Builds better immunity against colds and seasonal flu.

Our Vitamin D is:

• Made from natural ingredients.
• Laboratory-assayed to ensure quality — the same rigorous standard that is used for pharmaceutical drugs.
• Manufactured in a facility validated by NSF International to meet or exceed all government requirements for good manufacturing practices (the FDA's GMP's).
