Although current data support the viewpoint that the biomarker plasma 25(OH)D concentration must rise above 750 nmol/L to produce vitamin D toxicity, the more prudent upper limit of 250 nmol/L might be retained to ensure a wide safety margin.

What is the danger zone of vitamin D?

Some people are potentially at risk of inadequacy at 30 to 50 nmol/L (12–20 ng/mL). Levels of 50 nmol/L (20 ng/mL) or more are sufficient for most people. The FNB also noted that serum concentrations greater than 125 nmol/L (50 ng/mL) can be associated with adverse effects [1] (Table 1).

Which vitamin D level is too high?

Is it better to take vitamin D or D3?

While both Vitamin D2 (plant-based) and D3 (animal-based/sun-produced) raise vitamin D levels, D3 is generally considered better and more effective because it's the form your body makes, is absorbed more efficiently, and stays in your bloodstream longer to maintain healthier levels, making it superior for boosting and sustaining vitamin D status. Both can treat deficiency, but D3 is more potent and better at raising the crucial blood marker, 25(OH)D.
