Product Information

Directions for Use

Suggested Use: 1 capsule per day for 150 lb (68 kg) person. Smaller persons should space doses further apart (for example, every other day).

Warnings & Precautions

Do not use D3ZO concurrently with high-dose calcium supplements, as this could raise blood calcium excessively.

Additional Information

Vitamin D3 enhances dietary calcium absorption and raises blood calcium levels. Clinical studies have shown that higher consumption of vitamin D3 and higher blood calcium levels are correlated with lower incidence of cancer, bone fractures, and osteoporosis. D3ZO is a very high potency D3 supplement with added zinc to suppress the aging effects of higher calcium levels. See our website for details: www.lifelinknet.com/siteResources/Products/D3ZO.asp
