How a lot beta-carotene must you get? 

Because beta-carotene helps your physique create vitamin A, it’s an essential a part of a nutritious diet.

Let’s clarify. 

The higher restrict of vitamin A beneficial for adults over the age of 19 is 3,000 mcg per day. 

That’s as a result of vitamin A might be harmful in extreme quantities.  

Why? Vitamin A is a fat-soluble vitamin, which implies that your physique shops it in your liver and fatty tissue for use later. So, vitamin A stays round in your physique longer than water-soluble nutritional vitamins like vitamin C and B nutritional vitamins. Those move rapidly by means of your physique and get despatched out in your pee. 

Because vitamin A sticks round for use later, there’s a danger to getting an excessive amount of of it. That’s why vitamin A dietary supplements are usually not beneficial except they’re getting used beneath the supervision of a healthcare skilled — an excessive amount of of a very good factor is simply an excessive amount of.

And for others, dietary supplements nonetheless shouldn’t be your first path to upping your consumption of beta-carotene.

What’s extra is that it takes your physique a couple of further steps to interrupt down vitamins after they are available in complement type, versus pure sources.  

“It already takes your body some work to convert beta-carotene to vitamin A,” Sedlacek provides. “So, when you ask your body to first convert the nutrients from a pill into beta-carotene and then on to vitamin A, you can lose out on a lot of the benefits of the nutrients.”
