So, if you scrub your skin with soap in the shower, your body will not convert most of your skin’s sun exposure to vitamin D. I’m not suggesting that you avoid showering after sun exposure rather that you primarily soap the areas that don’t usually see the light of day and wash the newly tanned ones exclusively with water. Avoid excessive sun exposure since there are no health benefits of sunburn.
Some vitamin D deficiency symptoms include: bow legs or “knock knees,” burning in mouth or throat, constipation, dental cavities or cracked teeth, insomnia, joint pains or bone pains, muscle cramps, nearsightedness (myopia-can’t see distances), nervousness, osteomalacia, osteoporosis, frequent colds or flu, and poor bone development.
Vitamin D is also found in fish and fish oils, sweet potatoes, sunflower seeds, mushrooms, and many types of sprouts. People with low thyroid function (hypothyroidism) tend to have difficulty with vitamin D absorption and as a result, may have higher needs for this nutrient.
Most nutrition experts agree that the current RDA of 200 IU is insufficient and that the minimum needs to be raised to 1000 IU, while many health experts recommend supplementation of 2000 to 4000 IU daily. However, you should always consult a qualified health professional before supplementing with vitamin D since excessive amounts can build up in the body creating a potential risk for toxicity and is contraindicated for some health conditions.
