Dear goop, Is there a certain time of day that’s best to take vitamins and supplements? And should they be taken with or without food? —Cat M.

Hi, Cat. When it comes to taking supplements, those two questions often pop up. If you’re asking these questions, you’re probably already taking supplements, which is a great way to avoid nutritional gaps just in case your diet falls short.

If you’re still deciding which supplements are best for you with your doctor, consider your unique diet, lifestyle, and health. And you can discuss some of the research below with them too.

WITH OR WITHOUT FOOD
When it comes to individual supplements, the research gets more nuanced. Studies show that people tend to absorb vitamin D 50 percent better with the largest meal of the day. Taking algae and fish oils with food can improve absorption, but it depends on the type of oil and how it’s encapsulated. Either way, taking them with food helps minimize fishy burps. Combining turmeric with piperine, a compound in black pepper, may help its absorption. And pairing probiotics with meals may help more nutrients get into the body.

But some nutrients, like B vitamins, may be better absorbed on an empty stomach. A study showed an absorption increase of 33 percent for B12 and up to 117 percent for folate (B9) when fasting (compared to taking the supplements with meals). Iron is also better absorbed on an empty stomach but often causes an upset stomach when taken that way. And calcium can be taken with or without food,

MORNING, NOON, OR NIGHT
When to take your supplements depends on when you’re eating and sleeping, of course. Typically, consuming stimulating nutrients—B vitamins, green coffee bean extract, CoQ10, etc.—during the morning or early afternoon is best.

To keep us balanced and healthy, our bodies absorb only so much at a time. So spreading supplements throughout the morning and afternoon can help your body take in more of what it needs. In addition to taking your multis in the morning, taking vitamin D in the afternoon may provide better absorption, if that’s the time of your biggest meal of the day. And naturally, taking melatonin for occasional sleep support should be done at bedtime.
