I am highly skeptical of “miracles”. I am even more skeptical of supplements. Our body is a delicately balanced machine and if you try to tweak it by dramatically increasing just one micro-nutrient you risk throwing the whole machine out of kilter.
We were designed to run best on fatty meat as our primary food and it has been demonstrated by numerous aboriginal cultures to provide complete, health-giving nutrition. I eat a lot of aged cheese which is made from milk designed to rapidly grow infant bones and probably gives my old bones what they need. Meat is also a rich source of Magnesium. Vitamin A in my opinion is best acquired from sunlight exposure. Stock up in the summer as this is one of the 4 fat soluble Vitamins (A, D, E, &K) that are fat soluble and your body can store up for a wintry day. PS – Sunlight exposure is most likely not the cause of most skin cancers (the evidence actually points to the introduction of the widespread use of polyunsaturated vegetable oils and carcinogenic sunscreens like PABA containing products as the probable cause.
Here is what I’ve written about bones and supplements before.
“It’s been commonly accepted fact in the medical community for a while, that Calcium supplementation doesn’t work and increases the risk of coronary artery disease. I did however find 3 studies that I feel my fellow “top chain” carnivores will find exciting. First, a study on how bones got weaker when we switched to an agricultural diet! “Human Bones Have Gotten Weaker Since Paleolithic Times” and 2nd, Calcium uptake in the gut increases on a high protein diet and on a low protein diet, “Low Protein Intake: The Impact of Calcium and Bone Homeostasis in Humans” also, In a trial of Calcium and vitamin D replacement, high protein diets were associated with better bone mineral density scores. Exciting stuff, Eh?!”
Studies of Calcium plus Vitamin D do show some minor benefit but it’s probably all about the Vitamin D. Here’s the article on Calcium and increased myocardial infarction and cardiovascular events risk. I wonder how many doctors are aware? If I didn’t get much sun exposure I would definitely consider it, though the fossil evidence suggest that our hunter-gatherer ancestors in Europe did not suffer from Rickets (a Vitamin D deficiency caused bone disease) whereas when humans transitioned to an agricultural based diet rickets became rampant. The article is a very recent editorial on the status of vitamin D supplementation. I think it’s a fair and balanced presentation of the scientific data we currently have.
To summarize I would say that low vitamin D levels are associated with many medical conditions like heart disease depression etc. However, randomized studies have not shown a benefit for vitamin D high-dose supplementation so far. There are a lot of studies under way on this. My opinion is that if I lived somewhere where where it was impossible to get regular sun exposure, like the North Pole, I would either add liver or cod liver oil to my diet or I would take a low dose of vitamin D in the range of 800 international units a day. I don’t think most people in the US need to since in northern latitudes excess vitamin D from the summer is easily stored in the liver for use during the winter months. I think the widespread incidence of low Vitamin D blood levels in the US is probably related to poor diet (low fat, as fat is required for Vitamin D absorption, inflamed guts which makes Vitamin D uptake difficult, caused by high fiber diets and the widespread sun phobia and sunscreen use caused by the Melanoma phobia, when the real cause of the Melanoma rise is probably the sunscreen creams, increased citrus consumption and the rise in vegetable oil use which harms the immune system.
