Bone health and seasonal immune support
Vitamin D has long provided significant support for healthy bone density. However, vitamin D also plays a role in regulating healthy cell division and differentiation, and has profound effects on human immunity.
These findings link a deficiency of vitamin D to a host of common age-related problems. Vitamin D3 7,000 IU from Life Extension is a high-potency formula specifically designed to support your body’s immune system response during the time of year when you’ll need it most.
The current recommended daily allowance (RDA) for vitamin D is only 600 IU, which has resulted in startling evidence of a widespread deficiency for this vitamin. Most experts in the field now recommend intakes between 1,000−10,000 IU for adults to achieve a serum 25(OH)D level above those indicative of vitamin D deficient levels, at approximately 80 nmol/L or 32 ng/mL.
This 7,000 IU potency vitamin D is exactly what you need to promote immune support during the winter months. Please note that if you are already taking a multivitamin which contains Vitamin D, you should consider taking our Vitamin D3 5,000 IU supplement instead.
Increased Blood Levels
Life Extension suggests that healthy adults supplement each day with 5000−8000 IU of vitamin D with the objective of achieving an optimal 25-hydroxy vitamin D blood level between 50−80 ng/mL. A vitamin D blood test can help you determine the additional amount of vitamin D you may need to achieve an optimal level.
