Vitamin D3 by Life Extension – 60 Softgels

Life Extension Vitamin D3 5000 IU – Essential for Bone Growth, Density & Immune Health

Vitamin D3 (cholecalciferol) is one of the most critical nutrients for overall health — yet deficiency is widespread across all age groups. Life Extension's Vitamin D3 at 5000 IU (125 mcg) delivers a therapeutic-level dose in an easy-to-absorb softgel, supporting bone density, immune function, cardiovascular health, and mood. As the form your body naturally produces from sunlight, D3 is far superior to D2 for raising and maintaining optimal vitamin D blood levels.

Frequently Asked Questions

Is 5000 IU of Vitamin D3 safe?
For most adults, 5000 IU is a commonly recommended therapeutic dose, particularly for those who are deficient. The Tolerable Upper Intake Level (UL) set by health authorities is 4000 IU/day for general use, but many physicians recommend higher doses under supervision. Blood testing is the best way to determine your optimal dose.

Should I take Vitamin D3 with K2?
Yes — vitamin K2 (MK-7) works synergistically with D3 to direct calcium to bones rather than arteries. Consider pairing this with Life Extension’s Vitamin K2 for comprehensive bone and cardiovascular support.
