Question about my health? what's a good minerals and vitamin for age 20-40y?

Multivitamin: There are many multivitamins out there but one within your budget and suits your lifestyle: active/sport or a regular one should suffice. B-complex, vit d, vit e, vit k, and vit c are great and when combined with a regular healthy diet, will help. Its often better to get as many nutrients through foods as your body absorbs them better and provide fiber.
