Skin issues 7. Low back pain or muscle pain Vitamin D is one of the most important vitamins for overall health. It’s essential to make sure you’re getting enough. Unless you’re taking vitamin D or are getting plenty of sunshine every 24 hours—you’re likely vitamin D deficient. We also have to consider the factors that hinder vitamin D levels, such as: • Obesity • Insulin resistance • Diabetes • Lack of sun exposure • Lack of vitamin D in the diet • Aging Consider taking 10,000 IU of vitamin D3 daily. If you’re worried about vitamin D toxicity, keep in mind that if you go out in the sun for only 30 to 45 minutes, you’re getting about 20,000 IU of vitamin D, so 10,000 IU is not much for your body to handle. You should also get plenty of magnesium, zinc, vitamin K2, and boron when you take vitamin D.
