Vitamin D3

Nature's Sunshine Vitamin D3 provides 100 mcg of vitamin D3 (cholecalciferol) per serving—the more bioactive of the two forms of vitamin D. Often called the "sunshine" vitamin, it's designed to support your circulatory, immune, and structural health, especially during times when adequate sun exposure is hard to come by.

Vitamin D3 (cholecalciferol) helps regulate normal blood levels of calcium and phosphorus, which promotes strong bones and supports healthy bone mineralization. It also plays a role in supporting immune health and the cardiovascular system. Calcium is included as a key active ingredient, working alongside vitamin D3 to further encourage structural strength.

Take 2 tablets daily with a meal. Each bottle contains 180 tablets, providing a 90-day supply at the recommended serving size.

It's a great choice for adults looking to support bone density, immune health, and circulation—particularly those who get limited sun exposure due to climate, season, or lifestyle. Anyone who is pregnant, nursing, or on prescription medication should check with their healthcare provider before starting supplementation.

Vitamin D3 focuses specifically on delivering bioactive vitamin D3 for broad circulatory, immune, and structural support. If you're looking for a formula that pairs calcium with vitamin D, Calcium Plus Vitamin D or Sea Calcium may be worth exploring. For a broader mineral approach, Calcium-Magnesium (SynerPro) combines key minerals for structural support. Each product serves a slightly different need, so the best choice depends on your individual health goals.
