Vitamin D supplements are a popular dietary addition for those looking to boost their overall health and wellbeing. Vitamin D is essential for maintaining strong bones, teeth, and muscles, and it also helps to regulate the immune system. While the body can produce vitamin D naturally when exposed to sunlight, many people do not get enough from this source alone. Vitamin D supplements are available in a range of forms, including tablets, capsules, and drops, and they are often recommended by healthcare professionals to help prevent deficiencies.

Frequently Asked Questions (FAQs)

1. What is vitamin D good for?

Vitamin D is involved in calcium absorption, immune function, and protecting bone, muscle, and heart health. It occurs naturally in food and your body can also produce it when your skin is exposed to sunlight. Yet, aside from fatty fish, there are few foods rich in vitamin D.

2. What happens when your vitamin D is low?

Vitamin D deficiency can lead to a loss of bone density, which can contribute to osteoporosis and fractures (broken bones). Severe vitamin D deficiency can also lead to other diseases. In children, it can cause rickets. Rickets is a rare disease that causes the bones to become soft and bend.

3. Which fruit is rich in vitamin D?

Orange. There are limited Vitamin D fruits. Around 75% of the people worldwide are either allergic to dairy products or are lactose intolerant, and some of them are vegan. So, orange or orange juice is the best option with vitamin D and other nutrients such as calcium.

4. How do you get vitamin D?

Vitamin D isn't naturally found in many foods, but you can get it from fortified milk, fortified cereal, and fatty fish such as salmon, mackerel and sardines. Your body also makes vitamin D when direct sunlight converts a chemical in your skin into an active form of the vitamin (calciferol).
