Vitamin D3 is an essential nutrient that performs many important functions in the body.† Vitamin D3 helps support a healthy immune system, bone health & may promote a sense of overall well-being.†
Sunlight serves as the main source of vitamin D but - because many of us spend the majority of our days indoors - vitamin D deficiency has become more common. There are several foods that naturally contain this essential vitamin, including fish liver oil, eggs and fatty fish such as sardines and salmon.
For an easy, everyday way to support your vitamin D levels, consider supplementing with vitamin D3; other MegaFood options include Vitamin D3 1000 IU and Vitamin D3 1000 IU Gummies.
Consider speaking with a healthcare professional that can run blood tests and other labs. They will be able to guide you in the right direction based on your unique needs.
You can take Vitamin D3 2000 IU any time of day, even on an empty stomach.
