What's the Optimal Level of Vitamin D?
AI Summary of Video
- (00:00) The conversation opens by contrasting vitamin D from sunlight versus supplementation. They highlight that sunlight provides other benefits (e.g., nitric oxide production, physical activity) and can be a confounder when comparing it to supplements.
- (01:06) At the molecular level, once vitamin D is converted to its active form (1,25-dihydroxyvitamin D), it acts the same way whether it was produced from sunlight or obtained through supplements.
- (01:35) The body naturally regulates vitamin D production from sun exposure, preventing toxicity by stopping production once a certain threshold is reached—unlike with high-dose supplements.
- (02:06) Discussion about naturally high vitamin D levels: some people working outdoors (e.g., in tropical regions) can achieve high levels, but factors like skin pigmentation also influence how much vitamin D is produced.
- (02:37) Many studies suggest that levels up to 80 ng/mL may still be beneficial, lowering risks such as all-cause mortality. However, extremely high doses taken over long periods might lead to calcium-phosphorus issues.
- (03:36) They critique large vitamin D trials for using uniform dosages rather than individualizing to achieve specific blood levels. This design flaw may mask potential benefits of higher vitamin D targets (e.g., 60–80 ng/mL).
- (04:39) A major limitation in vitamin D research is that many trials only measure serum vitamin D levels in a small percentage of participants, making it difficult to draw strong conclusions.
- (05:06) Genetic differences (SNPs) affect how individuals respond to vitamin D supplementation; some people need higher doses to reach the same blood levels. Many large trials don’t account for these genetic factors.
- (05:34–06:33) The conversation touches on personal optimization (e.g., aiming for 50–60 vs. 80 ng/mL), potential interactions with hormones like estrogen, and the need for longer-term data on how vitamin D (and hormone therapy) affect health outcomes over time.

Introduction to Is 50 ng of vitamin D too high, just right, or not enough
- A few governments say 10 ng is OK
- Some governments say 20 ng is OK
- Some governments say 30 ng is OK
- Most experts say 40 ng is good
- Some experts say 50 ng is much better for disease prevention
- A few people think that > 80 ng is needed to deal with possible vitamin D restrictions due to genes
- One doctor found that >80 ng was the right level for 2,000 patients in his clinic
- Health problems that run in families are often associated with low vitamin D
- Some experts say 50 ng is too much
- Some concern that >40 ng may be too much if taking some fixed chemotherapy or not adjust cofactors
- Some experts feel 50 ng is not enough to TREAT some diseases
- Consensus: 0 ng is bad and 30 ng is good/ok
Notional Graph of Expert Opinions of levels with Vitamin D MONOTHERAPY
Note: Monotherapy just increases vitamin D levels, and rarely adjusts the cofactor intake (Ca, Mg, Vitamin K2, Omega-3, etc)
40-150 ng of Vitamin D needed to treat some health problems

Some categories of people are at High Risk of vitamin D deficiency
Those at high-risk of being Vitamin D deficient will require about 1.5X more vitamin D to restore their levels
Those who are at risk due to being obese need about 2X more vitamin D to restore their levels
