The Vitamin D Paradox: Why Too Many Supplements Can Be Bad

Here is a health paradox that everyone needs to understand: while Vitamin D is essential for your health, taking too much of it in supplement form can be dangerous. A medical expert explains this paradox and how to navigate it safely.
The paradox exists because Vitamin D is a fat-soluble hormone, not a water-soluble vitamin. Unlike Vitamin C, which your body excretes if you take too much, excess Vitamin D is stored in your body’s fat tissue.
The danger, as the expert warns, is that these stored levels can build up over time and become toxic. The most serious side effect of this toxicity is hypercalcemia (too much calcium in the blood), which can lead to kidney damage and other health problems.
This is why self-prescribing very high-dose supplements is a risky strategy. The sweet spot for most adults is a modest 600 to 800 IU daily, and this should always be discussed with a doctor.
The way to resolve this paradox is to use the body’s own safe and natural production method. Sunlight exposure allows your body to make what it needs and then it automatically stops production. This built-in off-switch is why 10-30 minutes of sun is the safest and most effective strategy.
