Are you getting enough Vitamin D?
Research suggests that Vitamin D is involved in follicle egg maturation and development. Many researchers believe the current amount for Vitamin D is set too low at 400 International Units (IU) daily and should be increased. The tolerable upper limit (UL) for Vitamin D is 2,000 IU per day, however, no adverse affects have been found up to 10,000 IU per day.
Few foods contain Vitamin D other than milk fortified with Vitamin D, eggs, liver, cereals with vitamin D added, and fatty fish. However, skin exposure to the sun provides as much as 80 to 90% of the body’s vitamin D – so the best advice is the outside.
Some studies show that there are certain people, those with darker skin, may be at risk for a Vitamin D deficiency as melanin blocks the conversion of active Vitamin D in the skin. Also overweight individuals have a greater chance of being deficient in Vitamin D because it is a fat-soluble vitamin and may not be as available in high amounts of fat tissue.
