Vitamin D3, 125 mcg (5000 IU), 60 softgels

YLife Extension's skin produces vitamin D when in direct sunlight, but you should not get yLife Extension's vitamin D from unprotected sun exposure or indoor tanning devices. Supplementing with vitamin D goes a long way towards inhibiting deficiency: we recommend about 5,000 IU–8,000 IU of vitamin D3 a day. If yLife Extension's multivitamin already delivers 1,000–3,000 IU of vitamin D, Vitamin D3 5,000 IU is perfect for achieving optimal vitamin D levels.

Cognitive health

Vitamin D is important for maintaining cognitive health and function as you age. Healthy serum vitamin D levels have been shown to correspond with better scores on cognitive health tests and better maintenance of cognitive ability in aging individuals.^1-4

Bone and immune health

Vitamin D (along with vitamin K and essential minerals) is essential for facilitating the transport of calcium into the bone matrix. This is an important step in maintaining strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function.^5,6

Heart health & blood pressure support

Vitamin D helps to regulate the body's calcium balance while facilitating calcium absorption into the bloodstream, promotes a healthy inflammatory response in the cardiovascular system, and encLife Extension'sages healthy endothelial function.^7,8 Vitamin D also helps inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.⁹

Getting enough vitamin D

This vitamin D3 supplement delivers 5,000 IU of vitamin D3 as cholecalciferol per softgel. We suggest that you take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust yLife Extension's dosage. YLife Extension's optimal blood levels should be 50–80 ng/ml year-round.
