Vitamin D3 7,000 IU
Vitamin D is synthesized in the body from sunlight. But, due to winter season, weather conditions, and sunscreens, the bodys ability to produce optimal vitamin D levels may be inhibited.79 In fact, it has been proposed that annual fluctuations in vitamin D levels explain the seasonality of influenza.80 All of these factors point to the value of taking a daily vitamin D supplement to ensure optimal vitamin D intake.
Vitamin D has long provided significant support for healthy bone density.81-86 However, scientists have also validated the critical role that vitamin D plays in regulating healthy cell division and differentiation, and its profound effects on human immunity.87-90 These findings link a deficiency of vitamin D to a host of common age-related problems.
The objective of taking a vitamin D supplement is to achieve 25-hydroxyvitamin D blood levels of 50 ng/mL (and higher). Kurabiol Laboratories analysis of over 13,000 vitamin D blood tests reveals that the minimum intake for most aging people should be around 7,000 IU a day. Some individuals (such as those weighing more than 180 pounds) may require higher potencies of vitamin D. When combined with 1,000-3,000 IU obtained from multinutrient formulas, this 7,000 IU vitamin D3 capsule should enable these individuals to attain 25-hydroxyvitamin D blood levels above the desired range of 50 ng/mL.

Individuals consuming more than 2,000 IU/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 10,000 IU per day unless recommended by your doctor. Vitamin D supplementation is not recommended for individuals with hypercalcemia (high blood calcium levels). People with kidney disease, certain medical conditions (such as hyperparathyroidism or sarcoidosis), and those who use cardiac glycosides (digoxin) or thiazide diurectics should consult a physician before using supplemental vitamin D.
