Every autumn, before the onset of winter, the sun sets further and further into the south. The days get shorter and the sun’s rays diminish in duration and intensity. This is when D3—” the sunshine vitamin”—blood levels drop.

​

That unnoticeable signal results in profound behavioural changes that are easily observed in foxes, bears, and many other land roaming creatures: their activity slows while their foraging increases. They are fattening up their calorie stores for the long winter’s hibernation.

​

With the advent of spring, the bright summer sun’s UVB rays once again are in play. This is where abundant D3 is synthesised from the photo-transformation of cholesterol. This hormone-like vitamin slowly absorbs into the blood stream where it is delivered to the liver, then to the kidneys, where it is finally converted into the activated form of vitamin D.

Rising levels of activated D signals renewed growth, heightened metabolic activity, better immunity, sharpened reproductive instincts, and accelerated tissue repair/regeneration. Rising vitamin D levels are synonymous with health, healing and vitality.

Re-calibrating Vitamin D Standards

In contrast, my training taught me only that vitamin D prevents rickets. Very small doses were all that was required to keep young kids from having weak, rubbery bones. vitamin D2 fortified milk was considered to be the solution. These small doses did stop the spread of endemic rickets.

​

Because vitamin D is a fat-soluble vitamin, the medical standard, until recently, was limited to only 400 IU (International Units) per day. The fear was that an excessive intake of vitamin D would build up in the fatty tissues of the body, possibly leading to excessive calcium absorption and toxicity. “Hyper-calcinosis” might then result in the formation of kidney stones, calcified arteries, and other manifestations of excessive calcium in the urine, blood, and body tissues.

​

Is vitamin D more a drug than a nutrient? It really depends on the dosage. It will probably come as a very big shock for our readers to learn that vitamin D3—cholecalciferol—is also used as a rodenticide! That’s right, vitamin D3, if given in a high enough dose over a short enough period of time, effectively kills rodents through massive hyper-calcinosis of their organs.

That fact sheds a whole new light on why many “old school” vitamin D researchers are very wary of patients “getting carried away” with their ultra-high doses of vitamin D3 as a modern cure all. Is vitamin D3 really the superhero nutrient ready to “save the day” …or could it be the malicious compound disguised as a “good guy”?!

​

Putting Safe D3 Dosing in Perspective

Up until recently, the highest dose of vitamin D3 we typically recommended at the Whole Is Well Clinic was 50,000 IU as a convenient once a week dose. Our maximum daily dose was 5,000 IU. This is a very safe dose as is documented on the website of the Vitamin D Council.  Children can safely take about 1000 IU for every 10 kg. of body weight.

​

There are other toxicity and sensitivity issues that can arise in the human consumption of vitamin D3. Generally, these can be avoided by having your 25(OH)D level measured once a year and keeping it around 60 ng/dl for optimal health.

Why Bother Taking Supplemental D3?​

Would Even Higher Doses of D3 Make Sense?

Given the over 56,000 published studies on the benefits of vitamin D3 when dosed optimally in humans, it only makes sense to wonder if higher doses might be of greater benefit in chronically ill patients.

​

The real question here is “What is an optimal dose?” Orthomolecular medicine is defined as “using the correct dose, of the right molecule, for the right condition, in the appropriately chosen patient.”

​

At the Whole Is Well Clinic, we are using this orthomolecular approach in our application of vitamin D3 in the care of patients suffering from sustained illnesses. However, we don’t just dole out vitamin D3 in a reckless manner. We use several principles of care and safety:

1. Patients as co-learners. Our patients are encouraged to read and be responsible and self-educated about their illness and the orthomolecular treatments they are using. We provide extensive info on vitamin D3.

2. Identify and treat actual causes. Rather than temporarily mitigating symptoms, this approach actively searches for and corrects underlying and sustained causes, such as vitamin D deficiency.

3. Characterize biochemical individuality. Measuring baseline vitamin D levels accomplishes two goals: diagnosis, plus the ability to verify correction of a deficiency later on when progress is being assessed.

4. Care for the whole person. Taking even the best vitamins at the optimal doses is never enough to maintain the “whole person perspective” in true health care.

5. Let food be thy medicine. Modern medicine may not even know about small amounts of phytonutrients that only whole foods can provide.

6. Cultivate healthy reserves. During challenging times of stress and illness, key nutrient reserves may get depleted. Plus, nutrients always work as a team.

7. The healing power of nature. The doctor treats, but nature heals.

D3:K2—The Birth of a Winning Combo

Speaking of team work, vitamin D3’s natural partner is vitamin K2. The genius of this combo begins with proper respect for D3’s function of powerfully enhancing calcium absorption. Recent research has shown that excessive calcium intake alone can be harmful to the body. The additional calcium must be correctly utilised or it can show up in the wrong places and cause disease.  By conscientiously using vitamin K2 in conjunction with D3, this issue of “metastatic calcium” is thoroughly avoided.

​

Vitamin K2 activates several important proteins in the body functioning including eight proteins which are involved in blood clotting.

A major medical misunderstanding surrounds vitamin K. Most doctors believe that vitamin K “causes” coagulation. It is true that babies born deficient in K need injections of it to restore coagulation. It is also well known that Coumadin, another rodenticide, poisons vitamin K coagulation function which does cause thinning of the blood. At really high doses this can kill a rat. At properly controlled doses, it can dissolve a threatening blood clot in a human patient.

​

The correct understanding is that vitamin K, through a chemical step called carboxylation, REGULATES and balances the coagulation system as a whole. Keep in mind that the coagulation system stands ready to CLOT if you are haemorrhaging to death, but it must also PREVENT THE CLOT if there are no lacerations or bleeding points. The eight proteins counter-regulate one another in this balancing act. Vitamin K is needed for this amazing deed.

​

Carboxylation of osteocalcin is another regulation feat of vitamin K which keeps bones properly mineralised with a strong protein matrix. Activated osteocalcin also stimulates adiponectin, a potent fat metabolism stimulator which helps people maintain normal weight. It is believed that all the antibiotics used in animal feed lots these days are finding their way into consumer’s guts where the beneficial bacteria that convert vitamin K into its active form are being badly disrupted. (Hence, low vitamin K in the body may be a contributing factor in the modern obesity epidemic!)

​

Activation of the vascular GMP protein is crucial in preventing calcification of coronary and carotid arteries. This explains the 50+% reduction in heart disease in regular vitamin K users. This same protein may also prevent bone spurs. Vitamin K is thus helping us age better with “hard bones and soft arteries” …not the other way around.

​

Finally, like vitamin D3, strong evidence demonstrates vitamin K’s amazing ability to reduce cancer risk. For example, men taking vitamin K2 mk7 (a naturally occurring long acting form of K2) at 45 mcg a day can statistically reduce their risk of prostate cancer by 60%! That is just one of many cancer risks that are reduced significantly by regular K2 ingestion.

As we explore the healing power of higher doses of vitamin D3 at the Whole Is Well Clinic, we have found it prudent to partner the safety and effectiveness of this dynamic duo. For every 5,000–10,000 units of D3 being recommended and tested for, we are recommending 100 mcg of K2 mk7 to be sure and prevent the inappropriate calcification that higher doses of D3 alone could cause.
