Safe Upper Limits and Monitoring
The safe upper limit for vitamin D supplementation is 4,000 IU per day for adults. But, everyone’s needs are different. It’s best to talk to a doctor to find the right dose and check vitamin D levels often.
Getting regular blood tests for calcium levels can spot hypercalcemia from vitamin D overdose early. If calcium levels are too high, stop taking vitamin D right away. Then, see a doctor to handle the risks of vitamin D overdose and hypercalcemia.

If you’re always tired and cold, vitamin D might be the answer. Eating foods rich in vitamin D or taking a supplement could change everything. It could help you feel more energetic and break the cycle of fatigue.
