Overview of Vitamin D

Vitamin D is a fat soluble vitamin present in some foods, in supplements, and when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis.

Vitamin D promotes calcium absorption in the gut and enables normal mineralization of bone. It is also needed for bone growth and bone remodeling. Vitamin D sufficiency prevents rickets in children and osteomalacia in adults 

At the cellular level, Vitamin D increases immune function, reduces inflammation and fights depression. Foods that contain D are:  Egg Yolks, fatty fish, beef liver, fortified milk. 

When taking supplements, it is important to choose Vitamin D3 as it is the one normally found in humans. 

Researches show that between 2000 and 4000 IU of Vitamin D taken between foods and supplements it is a safe amount,  with clinical data suggesting that  symptoms of toxicity are unlikely at daily intakes below 10,000 IU/day

How Does Vitamin D Affect Weight Gain?

Vitamin D and a hormone called leptin work together to regulate body weight. Leptin is produced in the body’s fat cells and works by sending a signal to the brain to let an individual know they are full and to stop eating. Vitamin D helps to keep leptin and this signal working properly, but when a person is vitamin D deficient, that signal gets disrupted and the body no longer knows it is full. This causes many people to overeat.

Vitamin D and Muscle abnormality

One of vitamin D's crucial roles in our bodies is keeping our muscles functioning and strong by helping them absorb calcium. While there's a lot we don't know about the little muscle abnormalities we call cramps, spasms, and twitches, it seems like not getting enough vitamin D may be one cause of those annoyances.
