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.
The upper limit for vitamin D is 1,000 to 1,500 IU/day for infants, 2,500 to 3,000 IU/day for children 1-8 years, and 4,000 IU/day for children 9 years and older, adults, and pregnant and lactating teens and women. Vitamin D toxicity almost always occurs from overuse of supplements.
