Vitamin D

Feb 09, 2022

Vitamin D

Vitamin D is an essential fat-soluble vitamin (meaning it is absorbed better alongside a source of fat from the diet) naturally present in few foods and produced in the body with sunlight exposure.

BONES AND TEETH Vitamin D aids in the absorption of calcium, maintains adequate calcium and phosphate concentration in the blood to enable normal bone mineralization and helps keep bones from becoming thin and brittle.

IMMUNE SUPPORT Vitamin D receptors are found all over the body, including in most immune cells. It helps to regulate the body’s immune response.

MUSCLE HEALTH Low levels of Vitamin D can cause muscle weakness, pain and loss of muscle strength. Adequate levels of Vitamin D can reduce muscle pain and increase function and strength.

NUTRIENT SHORTFALLS
