According to the NHS, taking high doses of vitamin A can cause some risks to a person’s health. For example, with age, they may be more likely to experience bone fractures if taking more than 1.5 milligrams (mg) of vitamin A each day.

Some foods naturally contain higher amounts of vitamin A, including liver. Eating liver more than once a week may also increase an individual’s vitamin A levels, so they should avoid taking supplements if they eat liver every week.

Further to that, pregnant people should consider limiting their vitamin A intake, as higher amounts can harm an unborn baby.

Side effects

Side effects that can develop when taking too much vitamin A include:

  • rough skin
  • dry hair
  • enlarged liver
  • nausea and vomiting
  • headaches

There are some factors that people may consider when looking for a vitamin A supplement product.

  • Instructions: Individuals should choose a product that includes a recommended dosage.
  • Form: Vitamin A supplements are available in different forms, such as capsules, softgels, and drops. A person can choose a product based on their preference. For example, those who have difficulty swallowing pills may prefer liquid options.
  • Ingredients: A person can choose supplements that are compatible with their diet, such as gluten-free or vegan.
  • Certifications: Individuals can find a company’s certifications on the product’s label or online page.

People who wish to know more about their vitamin A intake should seek professional help. A doctor can ask about the individual’s diet and how they can increase their vitamin intake if needed.

Those with deficiency symptoms should also see a physician for further evaluation.

In addition, anyone interested in buying vitamin A supplements should check with their doctor if these contain the right doses for them.

Below we answer some common questions relating to vitamin A supplements.

What is the best form of vitamin A?

The easiest way for a person to ensure they receive sufficient vitamin A is from foods. The ODS states that liver, fish, fortified cereals, and dairy products are the most common, vitamin A-rich foods. Foods containing provitamin A include carrots, broccoli, and squash.

However, some individuals may benefit from supplements if they have an increased risk of deficiency. These may include:

  • premature infants
  • those with cystic fibrosis
  • those with gastrointestinal conditions

How much vitamin A should you take each day?

The NHS states that males aged between 19 and 64 can take 700 mcg of vitamin A per day, and females in the same age range can take 600 mcg.

Individuals may find it helpful to take note of the foods they eat that may also contain vitamin A. This is because high doses may cause unwanted health complications.

What should a person consider when buying supplements?

A person should contact a doctor or healthcare professional before taking supplements as they can offer specific advice for the individual and ensure they are receiving safe vitamin levels.

However, as a general rule, a person can check the company’s certifications, manufacturing process, and product ingredients.

Is it OK to take vitamin A every day?

Vitamin A is important for a person’s body and a daily intake is usual, simply from diet alone. However, they should not exceed the current recommended daily intake, and consider the amounts obtained from food when also considering supplements.

Vitamin A supplements come in liquid, drops, or softgel form. They may suit those with a high chance of experiencing vitamin A deficiency.

Some supplements are gluten-free and may benefit those who follow a keto, vegan, or vegetarian diet.

However, a person should consider seeking advice from a doctor before committing to a purchase. This ensures that the supplement is safe and they receive the correct dose.
