Vitamin D Supplements

Known as ‘the sunshine vitamin’, vitamin D is created when sunlight touches the skin. The positive effects of vitamin D3 on healthy bones have long been recognised. What’s now becoming apparent is the many other ways it supports good health. Modern lifestyles mean that, for many, levels of this vital nutrient within the body have dropped.

Public Health England now recommends everyone in the UK take vitamin D tablets or vitamin D supplements in the autumn and winter. This is because vitamin D3, which we offer in our vitamin D supplements and vitamin D tablets, is important for your body’s processes. Our vitamin D tablets and vitamin D3 drops use the D3 form of vitamin D - the body's preferred form. Explore our great range of vitamin D supplements to see how you reach your daily vitamin D3 goals.

In addition to this vitamin D tablets can also help with maintaining your immune system. It’s great to stay on top of consuming your vitamin D tablets when it gets to winter and the nights get longer and darker. This is because we normally get our vitamin D from soaking in sunshine, which is limited in winter. Explore Nutri Advanced's range of vitamin D supplements...

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. This is a reason people begin to take vitamin D3 supplements. 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.
