I'm wondering what exactly the difference is between beans, lentils, grains, nuts, and seeds. For example, what's the botanical difference between black beans, green lentils, rice, almonds, and sunflower seeds?
1 Always take your vitamin D supplements with or right after you have eaten a meal. The food in your system will help your body to process this nutrient.  It doesnât seem to matter what meal you take your supplement with. The time of day does not appear to affect your bodyâs ability to absorb vitamin D.
How much vitamin D should adults take? According to the National Institutes of Health (NIH), the daily Adequate Intake (AI) for adults is 5 mcg (200 IU) daily for males, female, and pregnant/lactating women under the age of 50. People 50 to 70 years old should get 10 mcg daily (400 IU) daily, and those over 70 should get 15 mcg daily (600 IU). Based on recent research, Dr. Weil recommends 2,000 IU of vitamin D per day. Look for supplements that provide D3 (cholecalciferol) rather than D2 (ergocalciferol).
