Vitamin D - All you need to know
What is vitamin D?
Vitamin D belongs to the fat-soluble vitamins and can be formed by the human body itself, but it can also be absorbed through food. However, diet only has a small influence (about 10-20%) on vitamin D levels in the body.
Why is vitamin D actually important for the body?
Vitamin D contributes, among other things, to the normal function of the immune system, plays a crucial role in cell division and is important for muscle function, bones and teeth. Above all, vitamin D regulates the absorption of calcium in the intestine, which is ultimately important for bone mineralisation.
What are the benefits of taking vitamin D?
As already mentioned, vitamin D can be synthesised by humans themselves. This synthesis takes place in the skin and depends on the UV radiation of the sun. Both the dose of UV radiation and the synthesis depend on many factors, such as geographical latitude, weather, season, skin type, clothing, and cosmetic treatment of the skin.
What foods contain vitamin D?
Everyone can absorb vitamin D through their diet. It is one of the fat-soluble vitamins and is mainly found in foods of animal origin (e.g. salmon, tuna, herring). But vitamin D3 is also found in low concentrations in food products such as milk, dairy, or egg yolk. Vitamin D can also be found in plant foods such as mushrooms. However, this is vitamin D2.
Our Hey Sunshine Sun Vitamins and One Bear A Day Vitamins also contain vitamin D.

"Vitamin D is not only important for the immune system but plays an important role for our bones and muscles. That's why a good supply of vitamin D is essential for our bodies."
ALL QUESTIONS ABOUT VITAMIN D
ALL QUESTIONS ABOUT VITAMIN D
How often one should take vitamin D depends on each person. If you take in plenty of it through your diet or also get enough sun during the year and can thus cover your daily needs, an additional intake is not necessary. However, about 1 in 6 adults in the UK have low levels of vitamin D in their blood. 20% of the population suffers from a vitamin D deficiency. Additional supplementation is recommended. It's best to ask your doctor and have regular blood work done.
This depends mainly on gender and age, as well as various other factors, such as whether you are pregnant, breastfeeding, whether you have any diseases, or even how you eat. However, the NHS (National Health Services) recommends a daily amount of about 20 µg. However, it must be mentioned that the information from the NHS are recommendations and not maximum amounts.
Too much vitamin D can also lead to health consequences. However, there is no need to worry about overdosing on vitamin D due to sun exposure or diet. However, when supplementing vitamin D additionally, one should talk to the doctor beforehand to avoid possible health consequences. These would be, for example, vomiting, nausea, feeling weak, headaches, nervousness or, in the worst case, an overdose can even lead to kidney stones and damage.
