Have you been taking your multivitamin recently? No? Well, it’s high time that you cracked open that bottle again, people, especially if that little capsule contains B vitamins. 

Keeping on top of your vitamin B intake is one of the most bolstering habits you can develop for your metabolism, as a study published in Current Medical Science shows. Researchers found that supplementing the diet with B vitamins resulted in a boost to the metabolism in rats, which could have some seriously beneficial implications for humans, too.

And if you don’t have a bottle of vitamins close to hand, never fear — there are plenty of food sources where you can top up your vitamin B levels effectively. Fish and meat sources, like salmon, beef, and organ meats, are all abundant in the vitamins, according to Healthline. If you’re following a plant-based diet, though, never fear, as you can also get a good amount of B vitamins from sources like leafy greens, various beans and pulses, and nutritional yeast.
