Vitamin D: What’s the right level? – Harvard Health
To sum up, they estimated that a vitamin D level of 20 ng/mL or higher was adequate for good bone health, and subsequently a level below 20 was considered a vitamin D deficiency. In my practice, and in most, it is not uncommon to see a vitamin D level less than 20. When that happens, we tell the patient that they are deficient and recommend fairly aggressive replenishment, as well as ongoing supplementation. The majority of folks have a level between 20 and 40, in my experience …

Truly Optimal Vitamin D Levels Are Higher Than You Might Think
So if 30 ng/ml really doesn’t cut it for optimally supporting your health and well-being, what vitamin D levels should you strive to achieve and maintain? As an endocrinologist, I know that achieving optimal serum 25(OH)D levels in the 50+ ng/ml range is imperative for immune health, bone health, and more, Henderson says. This is the average or median level at which most association studies show various benefits, including immune health, balanced mood, and more.

If we measure vitamin D levels in those living traditional lives in the cradle of humanity, a normal vitamin D level would be over 100 nmol/L (40 ng/ml). So, maybe that should be the starting point until proven otherwise—a concept, regrettably, many guideline committees seem to have ignored.

Vitamin D: Optimal Levels and How to Get There
According to the Endocrine Society, vitamin D deficient adults should be treated with 50,000 IU (1250 ug) of vitamin D weekly [equal to 7143 IU (179 ug) daily] for eight weeks to achieve a blood level greater than 30 ng/mL (75 nmol/L). Maintenance therapy thereafter should be at least 1500-2000 IU (38-50 ug) per day.

RACGP – What is the optimal level of vitamin D?
Vitamin D assays are inconsistent and inaccurate and there is weak evidence around the level of 25-hydroxyvitamin D (25(OH)D) that is optimal. Evidence of links between vitamin D deficiency and disease come from observational studies and there is little support from randomised controlled trials of vitamin D supplementation. Where there is evidence of a link, increased risk is largely confined to very low 25(OH)D levels, with minimal health gains for 25(OH)D levels greater than 50 nmol/L. New …

Vitamin D status plays a major role in overall health, wellness and longevity. Optimal blood levels of Vitamin D are 60 to 90 ng/ml and anything less may increase your risk of developing chronic health conditions. Replenishing vitamin D levels is not difficult. If you are low, allow 3 to 6 months of a higher dose of 5,000 to 10,000 UI per day of vitamin D3.

Here are some tables to help you make sense of all these numbers.
