What is an Optimal Vitamin D Level?

This is a question that has not been answered in the scientific or the clinical community, so is difficult to come to an agreement on this topic. But we do think that there are some common trends between the different recommending groups, between the different organizations. Looking at the original research as well as the current recommendations, we at OmegaQuant came to set our optimal target at 30 nanograms per milliliter as a plasma level of total vitamin D. This 30 nanograms per milliliter has been shown in many epidemiological studies as a “Goldilocks” level — not to low, not too high, but just right. So, this is where the point where people who have 30 to about 50 nanograms per milliliter tend to have the lowest risk of dying from all-causes, lowest risk from dying from cancer, lowest risk from dying from cardiovascular disease. So, these long chronic diseases, people with these 30 nanograms per milliliter of vitamin D have lower risk compared to people who have lower levels. There's also evidence that in pregnancy, women with a level of 30 nanograms per milliliter are at the lowest risk of preterm birth. So, there's a lot of different lines of research that point at this number being the best bang for your buck. You can go higher, but 30 is really where your risk is lowest. And then after that, once you get higher and higher vitamin D levels, the risk doesn't continue to go down. It plateaus. In some cases, it starts to go back up again once you get into the very high vitamin D levels above 100 and 150 nanograms per milliliter. So, you may notice that I have not talked about bones in relation to these optimal blood levels. And most of the bone research is showing that lower levels, the current recommended lower levels were being at 20 nanograms per mil should be protective against fracture and rickets. When you are at 30 nanograms per milliliter, you're beating that target, you're not adding any extra risk. And so, we think 30 nanograms does cover the bone health piece of this. The other number that is important is 12.5 nanograms per mil. And that's where there’s a real true deficiency. So, if you're below that, those are people who need to be working with their health care provider to raise their levels up as quickly as possible. So, if you're between the 12 and the 20 or 12 and the 30 nanograms per milliliter, there's a lot of different terms like insufficiency and sufficiency. But if you get to 30 nanograms per milliliter, then you know you are well covered and you are probably in the best place you can be for long-term health.

Dr. William Davis considers OPTIMAL levels as 60-70ng/mL. With about 9 out of 10 Covid deaths in those Vitamin D deficient, aiming for optimal rather than "suggested" seems the smarter choice.

Ya’ll might be confusing ng/l with nmol/l. She’s suggesting 75-125nmol/l

Seems to low from the research I did it seems like the Goldilock area is around 50

I live in Minnesota and take 4-5000 IU in the summer and 6-7000 IU in the winter. My blood level was at 61. This was this past June. 😊

In the market, we are getting Vitamin D3 [5, 000IUs] and D3 [10, 000IUs] per capsule, so how much is your optimal level of Vitamin D [30 nanograms per milliliter] in terms of IUs?

[garethpowell]

Americans: optimal level is 100-150ng.
Brits: optimal level is 250-375 nMol.
You’re welcome.
