Vitamin D is an essential nutrient that helps the body absorb calcium, maintain strong bones and teeth, and support a healthy immune system. While our bodies can produce vitamin D with exposure to sunlight, many people do not get enough of this nutrient from natural sources. Vitamin D supplements are a convenient and effective way to ensure you are getting enough of this important vitamin. There are a variety of vitamin D supplements available on the market, including tablets, capsules, and drops, making it easy to find one that suits your needs.

Frequently Asked Questions (FAQs)

1. Is vitamin D supplement good for everyone?

Should everyone be taking vitamin D? Vitamin D is said to help stave off fatigue, depression and even cancer. But some experts argue that for people with healthy levels, supplements are not helpful.

2. What is the best form of vitamin D to take?

In supplements, two forms of vitamin D are available: D2, which is called ergocalciferol, and D3, which is called cholecalciferol. Both are effective, but D3 seems to be more effective at higher dosages.

3. Can I take vitamin D supplements everyday?

The current recommendations suggest consuming 400–800 IU (10–20 mcg) of vitamin D per day. However, people who need more vitamin D can safely consume 1,000–4,000 IU (25–100 mcg) daily. Consuming more than this is not advised, as it is not linked to any extra health benefits.

4. Should vitamin D tablets be taken all year round?

Any one at risk of not getting enough vitamin D should take a vitamin D supplement – especially during the winter months but ideally all year round.
