Vitamin A – Beneficial Or Toxic? The Answer Lies In Moderation.

When researchers were studying this particular vitamin, it was found that vitamin A was pretty useful. Vitamin A doesn't just keep our eyes healthy, but it also aids cell growth and boosts our immune system. What differentiates it from the other vitamins is that it isn't absorbed directly. Instead, your body creates it by converting beta carotene into Vitamin A.

Found in a large variety of foods, you're likely to consume sufficient amounts of Vitamin A if you've eggs, milk, liver and meat in your diet. What's more, beta carotene that the body can convert into Vitamin A is found in many fruits and vegetables.

Because it can be so easy to consume Vitamin A, it's important that you remember not to take too much pure vitamin A. An overdose of Vitamin A can actually be toxic and it's important that you do not exceed the recommended daily allowance. The actual recommended allowance of Vitamin A varies depending on a person's age, sex and other factors.

Vitamin A is produced from the high levels of beta carotene found in vegetables. Other foods which contain high levels of beta carotene include tomatoes and dark green leafy vegetables, such as spinach.

Beta carotene is not only used to form vitamin A, but it is also a powerful antioxidant. None of the beta carotene that is absorbed is wasted as any excess after conversion to Vitamin A is used to fight the harmful free radicals within the body. Vitamin A also helps fight infections and illnesses by helping tissues that line various parts of the body, including the eyes, mouth, nose, throat and lungs, to grow and also to repair them if they are damaged.

As an adult, it is important that you're consuming the right amount of Vitamin A. You can't take too much and you can't have too little either. To find out the recommended dosage of Vitamin A, consult your local doctor to know if supplements are needed to boost the amount of Vitamin A in your body.
