The intestines have a limited ability to absorb vitamin C. Studies have shown that absorption of vitamin C decreases to less than 50% when taking amounts greater than 1000 mg. In generally healthy adults, megadoses of vitamin C are not toxic because once the body’s tissues become saturated with vitamin C, absorption decreases and any excess Too much vitamin C may cause digestive symptoms. The most common side effect of high vitamin C intake is digestive distress. In general, these side effects do not occur as a result of eating foods The dietary reference value (DRV) for healthy adults (over the age of 18) is between 95-110 mg of vitamin C per day. During pregnancy and lactation, needs can go up to 105 mg and 155 mg of vitamin C per day, respectively. We can get enough vitamin C from our diets by eating a variety of foods.

Other winning combos include iron and vitamin C, as Vitamin C helps the body release a higher percentage of iron. “In a study we did, taking iron with vitamin C Some research suggests that vitamin D may be harmful without vitamin K to offset its effects, but more research is needed in this area. Getting adequate amounts of vitamin D and vitamin K is Say you take a 5,000 IU dose of vitamin D and soon after develop diarrhea, intestinal cramping, or some other digestive problem. Your doctor will tell you that you are experiencing vitamin D toxicity symptoms. That might make you stop taking vitamin D, which would be a real shame, as the vast majority of us are vitamin D deficient. In the summer in Miami -- with 25 percent of the body exposed to the sun -- a person would need only 3 minutes of sun exposure to make a sufficient amount of vitamin D. That same person -- when placed in Boston in the winter -- would need 23 minutes at noon to produce enough vitamin D. Then again, Boston in the winter is really cold, so you Folate (vitamin B-9) is important in red blood cell formation and for healthy cell growth and function. The nutrient is crucial during early pregnancy to reduce the risk of birth defects of the brain and spine. Folate is found mainly in dark green leafy vegetables, beans, peas and nuts. Fruits rich in folate include oranges, lemons, bananas Vitamin D is necessary for strong bones and muscles. Without Vitamin D, our bodies cannot effectively absorb calcium, which is essential to good bone health. Children who lack Vitamin D develop a condition called rickets, which causes bone weakness, bowed legs, and other skeletal deformities, such as stooped posture. Nf9ItGf.
