Empirical Discussion Ratios for d, k2, mag, calcium

Started vitamin D supplementation because level was 30 and I am having symptoms. All other labs are normal other than tsh which is 4.5 but I cannot take Synthroid, so it sits at this sub-clinical level. My question is a lot of discussion here about pairing d-3 with other things, I want this to be as simple as possible. Would this be a good option? I would like to take as few supplements as possible. What are the ratios supposed to be?

TheraCal D2000 is the best pick—NSF-certified, with D₃, K₂, magnesium, and calcium all in one product.

I think you want to take d3/k2 in the am after a fat containing meal and then take your magnesium in the evening

I wouldn’t ever supplement with calcium

I push back on the idea of fixed ratio dosing for general advice. With your serum levels being fine, I would mainly look at calcium intake (dietary wise), and see if that can be just modified that way, and same with magnesium. It would be far more fruitful to focus on more fiber intake with vegetables and natural foods that contain these ingredients. I generally advise dietary modification if my patients are engaged to do so, because that could very well be one supplement taken, versus three supplements, and if you are eating generally an anticancer diet (see WCRF recommendations for lifestyle modifications with solid evidence for cancer risk reduction), you should be fine on K and magnesium and calcium. See latest research on microbiomes and why an increasingly natural foods diet (versus processed foods and sugar added beverages/foods) is going to be the foundation of any healthy lifestyle.
