Safe dosage for vitamin D?

The safe dosage for vitamin D varies depending on individual needs and circumstances, but general guidelines can be provided. Andrew Huberman suggests that for most people, supplementing with 1000 to 2000 International Units (IU) of vitamin D per day is likely safe and effective in maintaining adequate levels. However, he also notes that some individuals might need higher doses, such as 5000 to 10,000 IU per day, based on their specific health conditions and after verifying their levels through blood tests 1.

It's vital not to exceed safe upper limits without medical supervision because excessive vitamin D intake can lead to negative health effects. As discussed during the podcast, while hypercalcemia (high calcium levels in the blood) is a major concern with very high levels of vitamin D supplementation, it is generally hard to reach such levels with standard doses. Therefore, a typical safe range for most people could be from 1000 to 5000 IU per day 2. Always consult healthcare providers to tailor dosages to your individual needs, particularly if you chose to take amounts at the higher end of the spectrum.
