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.
Spend some time outdoors in the sun every day to bring your vitamin D3 levels up fast. Just 15 to 20 minutes of sun exposure daily can prevent vitamin D deficiency in most people. Those with darker skin tones might require more time in the sun.
