What's the Perfect Vitamin D Dose?

Supplementing with 1,000-2,000IU of Vitamin D is in line with the guidelines from the Endocrine Society. Supplementing with higher doses however is not justified from the current human randomized controlled trials 💊MicroVitamin (multivitamin & mineral that I take): drstanfield.com/products/microvitamin 📜Roadmap - how to look young & feel strong: drstanfield.com/pages/roadmap

Define mega dosing vitamin D please. It's the only contra indicator, and you don't define it. Is 5,000 IUs mega? 10,000? Give us a ballpark

That is misleading. The purpose of taking high doses of vitamin D is to achieve an optimal vitamin D supply in a short period of time. Once you have reached this level, you should of course not continue taking high doses, but take a maintenance dose. And off course, this all presupposes that you have your levels tested.

You are wrong on this matter. Vitamin d3 toxicity happened only to those individuals who took 60k iu per day for several days due to ignorance, and you conveniently mentioned those news without fact checking what really happened. Other factors you missed are : 1. Skin colour 2. Geo location 3. Sun exposure - some people like me prefer to stay out of sun. I take around 10k iu per day, and my blood test gave me a level of 77, so I decided to cut it down to 5k iu per day, then it dropped to 55. So I am back on 10k iu again. How much d3 supplementation a person needs is a very individual specific goal, either they should get their blood tested done every month to check their levels or take right dose under medical supervision:

My vitamin D level test revealed that my supplement dose was not enough to elevate my levels correctly, so it helped me get that corrected.

If I stop taking vit D and K2, I get shin splints from sports and my joints start hurting and popping. I'm never stopping it.

My strictly anecedotal experience with megadosing D3/K2 + Mg: ten years ago I was diagnosed with inverse psoriasis of the inguinal area at age 54. For years I tried to manage it using various topical ointments, both Rx and OTC. It was not until I started taking 20,000 IU of D3 each day (along with commensurate amounts of K2) that I experienced lasting relief. I kept up this regimen for about two years, after which I decreased to 10,000 IU, which is my current dose. I've never had any of the symptoms of D3 toxicity, but I'm mulling over whether to get a blood test, just to get an idea of where my longtime regimen has left me. Update: soon after posting this comment, testing revealed that my D level is 106 ng/ml--slightly elevated but nowhere near the danger zone (which I've seen defined as either 150 or 200). So take my experience with years of high-dosing D3 into account as you weigh your own regimen!

I love my D3 and K2. Just got tested and my D levels are 100 and I’m Black.

Britain's version of NIH did a large study after COVID-19 and found there was a direct correlation to vitamin D levels and illness severity. The lower the levels the more severe the patient.

The nutrition studies will always be way off the mark, because they test everything in isolation. The problem is that whole-body biochemistry isn't something that can be accurately isolated. So the institutional stance on most nutrition topics is just a massive fail. Especially regarding optimization.

Better not to measure than to measure? Seriously?

I have been mega dosing for almost 2 years now, taking 300,000IU every 3-4 months or so, also get sun light everyday, i dont even take vitamin k2 i try to get it from real food, every time i take the mega dose i feel amazing its the best thing ever i havent had a single down side and have given it to family members too they have also benefited a lot from it however being deficient in vit-k2 is not good if u want to mega dose vitamin d3 because you will have some temporary side effects, also when mega dosing like that u have to drink more water to be safe from any kidney problems too, its amazing i will forever mega dose it really if my levels go down, first time i took the mega dose my depressions, energy, testosterone, honestly it was just so amazing they all got a lot better! my testosterone alone went up by 110 even tho i didnt even change diet or training, i recommend everyone to take at least 10,000iu daily if ur deficient and 5,000 daily if u want to maintain ur levels

I've recently heard from multiple sources that though sun exposure is linked to fairly harmless basal and squamous cell carcinomas, a lack of sunlight is linked to increased incidence of very deadly melanomas.

It takes 10,000 iu’s to get my levels to 90. Everyone’s different.

The main problem with this video is that there are no randomized clinical trials with "megadoses" of vitamin D3, K2, and magnesium. What he call "megadoses" is something like 0.125 mg, or 0,250 mg (which is 10'000 IU). Harping about almost no effect in clinical trials designed for failure is pretty inane! By the way, I see the effect of low vitamin D daily, in form of too many over 65 who can't walk without pain, and often has to use a walker. And even younger who have operated knee or hip joints. I guess this doctor beleive that's natural ageing!

The New Zealand system recommends insulin for type 2 diabetics so yeah, i wouldn't put NZ at the forefront of metabolic health advice...

I'm not sure I agree with Dr. Standfield regarding the observational studies vs. the controlled trials. The reason is those trails are only looking at a relatively short window of time relative a lifetime of low vitamin D. For example, in a six month study there might not be any significant differences in cancer rates since the chance of anyone getting cancer in the time frame is low, etc.

142 nmo/L here, 66yo. Been taking Vitamin D for years, in the past year, between 2500 and 3500IUs a day. My wife, a GP, has been taking Vitamin D for about ten years, and it has done a great job preventing the cold sores she used to get regularly. Think its help me prevent complications of viruses like the flu.

All well and good but you neglect to mention that many older people struggle to make enough and/or absorb vitamin D. Even with plenty of sun I still need 5000 iu per day just to keep my levels around 50. One size does not fit all. You should clarify this point about older people.

The 89 year old who died from vitamin D toxicity. That article at the 15 second mark says: “Excess D wasn’t the only cause of death listed — the coroner also blamed congestive heart failure, chronic kidney failure, hypercalcemia, and Ischaemic Heart Disease — when blood no longer flows efficiently to the organ.” He was 89.
