Vitamin D; should we supplement?

Vitamin D; should we supplement?

Vitamin D has been touted as somewhat of a cure all but is this the case? Instead it’s important to look at the bigger picture and ALL of the nutrients involved in the production of vitamin D.

With widespread advice to supplement vitamin D3, it’s important to really understand what vitamin D supplements actually do in the body.



Vitamin D is a hormone-like vitamin that comes from plants as D2, or from animal sources as D3. The most potent form is vitamin D3.

Vitamin D from the sun is a totally different form of D3 (it’s attached to a sulfate) to D3 in supplements. It’s treated & stored differently, so try to expose your skin to the sun daily where possible (15-30 mins, or half the time if your skin turns red). Sunscreens block production of vitamin D.

Obtaining vitamin D from animal sources is also advised: egg yolk, meat & fish (e.g. salmon, mackerel & trout).


What Vitamin D supplements do in the body:

High doses of vitamin D supplements can cause:

  • Potassium to decrease, which can cause so many symptoms such as constipation, irregular heartbeat or sleep issues.
  • Magnesium to be depleted, which causes a whole cascade of symptoms from anxiety, blood sugar imbalances to headaches & muscle aches.
  • Calcium to increase. We don’t want high calcium levels, because it starts entering tissue including the arteries. Calcium belongs in the bone, not in the tissues. Increased calcium in tissues can cause a general slowing down over time, premature ageing & many of the chronic degenerative diseases.
  • A knock on effect of these mineral imbalances can affect the thyroid (e.g. fatigue, weight gain, depression, muscle aches & dry skin).
  • If adrenals are fatigued, Vitamin D will bring on even more exhaustion & fatigue.
  • If you are low in vitamin A, too much vitamin D supplementation is thought to be toxic.
  • Vitamin D supplements can be hard on the liver or kidneys if they are weak.


The real reason for low vitamin D:

Only in very few cases, do I recommend a vitamin D supplement. Instead, vitamin D3 needs other nutrients for its production including magnesium, potassium, boron  & vitamin C. Once these minerals are restored vitamin D3 levels naturally return to normal.

That’s why we use hair mineral tests to track these minerals.

We also need to support the liver, kidneys, gut and thyroid to really make the Vitamin D available.
