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.
Bottom line: Vitamin D intake is recommended at 400â800 IU/day, or 10â20 micrograms. However, some studies suggest that a higher daily intake of 1000â4000 IU (25â100 micrograms) is needed to maintain optimal blood levels.
