Vitamin D Supplements

Vitamin D has long been recognised by health professionals for its positive effects on the body. Vitamin D promotes healthy bones as it helps to regulate the calcium and phosphate in the body. We need these nutrients to keep our bones, teeth and muscles healthy. Vitamin D supplements also play a role in maintaining bone structure. This is why vitamin D3 supplements have been increasingly popular in recent years.

It is now becoming apparent that vitamin D supports good health in many different ways. For this reason, vitamin D3 supplements have become a staple in many people’s diets. As a result of modern lifestyles, levels of this vitamin have dropped significantly, so Public Health England now recommends that everyone in the UK take vitamin D supplements in the autumn and winter. There are a range of different forms of vitamin D that can be found in fish, eggs and fortified milk. We also produce this naturally when our skin is exposed to natural sunlight and it is then stored in our fat for when the sun goes.

A person with a vitamin D deficiency has low levels of the vitamin in their blood. A vitamin D3 deficiency in children can lead to rickets, a condition that results in bone deformities and in adults, a deficiency can cause osteomalacia which causes bone pain.

Low vitamin D3 levels can also lead to less severe symptoms such as poor muscle strength, a weakened immune system and feelings of fatigue.

In the UK, it is recommended that adults and children over the age of 4 should consider taking a vitamin D supplement in autumn and winter when the sun is not strong enough for your body to produce vitamin D in response to sunlight.

Taking the correct dose of vitamin D3 supplements is very safe. However, if your vitamin D3 levels are too high over a significant time period as a result of taking the wrong vitamin D3 supplement dosage, this may cause too much calcium to build up in the body which can result in weakened bones and damage to the kidneys and the heart. Therefore, it is important to regularly get your vitamin D3 levels tested when taking high strength vitamin D3 supplements.
