When to take a supplement depends largely on what kind you’re taking. But make sure you really need to take one in the first place.

If you’ve ever wondered when you should be taking your vitamins — Breakfast? Lunch? Whenever you remember to? — depends on the type of vitamins.

That’s because vitamins are a synthetic substance and are best absorbed in your body when they are taken with food and its naturally occurring vitamins. Taking them in the morning allows for the best chance that they’ll be absorbed into your system with the food that you eat all throughout the day....
