Vitamin C, otherwise known as ascorbic acid, is an essential nutrient that has a lot of benefits.

It is known to give your immune system a boost to help fight off diseases and cure various health conditions. Vitamin C also keeps your heart and brain strong and improves collagen production, keeping your skin soft and healthy. It also guards against UV rays to prevent cancer-causing oxidative damage and keeps your energy levels up.

Vitamin C is a very important nutrient, which makes it unfortunate that our bodies can’t produce it on their own.

Luckily, there are plenty of ways to get your RDA (recommended daily allowance) of Vitamin C, which include fruits, vegetables and morning sunlight. Any of these can give you a high dose of vitamin C benefits.

But, if these aren't available to you at the moment, there are plenty of vitamin C supplements that can provide your daily dose of vitamin C.

Depending on the supplement, these can give you either the recommended dosage of 75 to 90mg or a higher dose of up to 1,500mg per day. It's also important to avoid taking mega doses (more than 2,000) of vitamin C per day, as this can lead to unwanted side effects.

Here are the best vitamin C supplements for adults, which should help you stay healthy as COVID restrictions slowly relax.
