Great tip. Thank you. I have been taking 5000 iu of D with K2 but am 20 lbs overweight. Last year my D levels between 50-60. Should I take more? Need to share this with my pharmacologist friend.

Assuming your body weight is 175 lb, this is 80 kilograms. Prof. Wimalawansa's recommendation for people who are underweight, normal weight or overweight is an average daily vitamin D3 supplemental intake of 70 to 90 IU per kg body weight. This is 5600 to 7200 IU a day. For those suffering from obesity I or II, he recommends 100 to 130 IU / day / kg body weight. This implies that those who are overweight should take on the high side of the 70 to 90 recommendation, or use 100 if they think they might be suffering from borderline obesity.
The aim of his recommendation is most or all people who follow them will, after several months, attain at least the 50 ng/mL circulating 25-hydroxyvitamin D level their immune system needs to function properly. Many people will attain more than this - but few would attain more than twice this, since the body has self-limiting mechanisms which make it progressively harder to raise 25-hydroxyvitamin D levels.
You have attained 50 to 60 ng/mL with 5000 IU vitamin D3 a day. (Doctors in the UK, Australia, New Zealand and perhaps Canada use nmol/L for 25-hydroxyvitamin D levels, which are 2.5 the figure in nanograms per millilitre. So the target is at least 125 nmol/L.)
I am an electronic technician and computer programmer - not a doctor. Please refer to Prof. Wimalawansa's recommendations. My impression is that you are doing fine.
Vitamin K2, of the MK-7 form, such as 0.2 milligrams (200 micrograms) a day for average weight adults is widely regarded as helping maintain calcium in the bone and reducing the tendency of high (well beyond your level) 25-hydroxyvitamin D levels to take calcium out of the bone and raise calcium levels in the blood. (Beyond narrow limits, this is hypercalcemia, which causes serious long-term health problems.) I have not surveyed the research fully, but this is a good article to start with: https://www.hindawi.com/journals/jnme/2017/6254836/ and https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4566462/ .
When I was working as a nurse practitioner, if I knew the person’s vitamin D level, I would advise the person to take 1000 IUs for every 10 ng/ml I wanted to raise his vitamin D level. For example, if he had a level of 40ng/ml, I would advise him to take 2000 IU/day to get him up to a level of about 60ng/ml. This was a simple formula that worked pretty well.
Great essay Robin and further comments. Well researched. There was a study in, I believe Indonesia, in early 2020 that found that 99% of those hospitalized had low levels of vitamin d and recommended that everyone get their levels up. This study was ridiculed but subsequent studies have, as you indicated, confirmed it was right. Dr. Campbell had several videos on the effectiveness of vitamin d. The medical authorities ignored all these recommendations. Even Dr. Fauci acknowledged that he took 5000 units of vitamin d but he never promoted it. This is a video with Dr. Campbell and Dr. David Grimes on the benefits of vitamin d. https://www.youtube.com/watch?v=2hO7fniCbmw Dr. Grimes is a pioneering researcher on vitamin d. Confirms what you have written. Everyone should get their vitamin d levels checked and work to get them up.
My weight fluctuates between 140-145 for a 5 ft 2” 70 year old, otherwise generally healthy female who hasn’t been successful in achieving a desired 130 weight. I used to be 120 before I got my uterine cancer which required radiation. I also have have been dealing with chronic leg lymphedema and chronic leg cellulitis for over 20 years (due to a damaged lymphatic system from my pelvic radiation) and survived 5 sepsis infections in the last 10 years. Been on repetitive pill form and iv antibiotics for my frequent recurring leg cellulitis. The importance of vitamin D was revealed to me only within the last 4 years during the worlds COVID scare. I refused to submit to the the MRNA injections and was reading up on folks like Dr. McCullough. None of my Ivy League doctors educated me on maintaining a healthy level of D. A few times my endocrinologist put me on a short regimen D / 50,000 units daily. I need to find a functional medicine doctor in the Lancaster PA area. Two of my well respected NYC oncologists who I recently left due to my relocation just announced in the last 2 weeks that they’re closing their NYC upper east side private practices. Isn’t that weird?
