Apollo's Hegemony+ Vitamin D3 is a dietary supplement containing vitamin D3 at 4000IU dose per serving. 

Vitamin D3 (cholecalciferol) is a form of vitamin D derived from animal sources and naturally formed in the body through dermal synthesis during exposition to sunlight. 

Vitamin D has a wide spectrum of activity. This is due to the presence of specific receptors for vitamin D compounds in many types of cells in the body - including bone cells, intestinal epithelium, heart, brain, and some cells of the immune system. 

The most important function of vitamin D is participation in calcium-phosphate metabolism and maintenance of healthy bones and teeth. In addition, vitamin D participates in normal muscle function, supports optimal immune system response, and is involved in cell division processes.

In conclusion, Apollo's Hegemony+ Vitamin D3 is a dietary supplement recommended to complement the diet with an additional dose of vitamin D3.
