Vitamin A in the diet can come in different forms: retinol, beta-carotene, alpha-carotene, and beta-cryptoxanthin. If you suffer from a disease that makes it absolutely necessary for your vitamin D level to be in the optimal range, or if you want to know your exact level, then you should have your vitamin D level measured. The blood test to measure your vitamin D levels is called the 25(OH)D blood test. You should not exceed the recommended dose of 1 supplement per day. This level of intake is designed to meet the needs of your body. It’s not a good idea to take more at the moment. Is 12.5 ug vitamin D enough? Between late March/early April to the end of September, most people can make all the vitamin D they need through sunlight on their skin and from a balanced diet.

You can buy vitamin D supplements or vitamin drops containing vitamin D (for under 5s) at most pharmacies and supermarkets. Reviewed all substances and their conversion factors. Added links on reliable sources for each substance. Do not take more than 100 micrograms (4,000 IU) of vitamin D a day as it could be harmful. This applies to adults, including pregnant and breastfeeding women and the elderly, and children aged 11 to 17 years. This can cause low blood vitamin D levels, especially during winter months when there is even less sunlight. Since everyone absorbs vitamin D differently, the 25(OH)D value may develop differently. This means that not ever person will achieve exactly the same 25(OH)D level in their blood even if they take the same dose of vitamin D.Added translations and language selection for French (100%), Turkish (19%), Chinese (18%).

From 10000 to 25000 IU of vitamin D can be produced endogenously when exposed to one erythemal dose of UV radiation (leaves a slight pinkness in the skin 24 hours following exposure). Endogenous vitamin D remains in the blood longer than ingested vitamin D.[xvi] Vitamin D is one of the body’s most important vitamins, helping it with a variety of tasks: Vitamin D contributes to the normal function of the immune system and is very important for the body’s structural system, maintaining normal bone and muscle function. Vitamin D3 also contributes to the normal absorption and utilisation of calcium and phosphorus.

As vitamin A has many functions in the human body, itsdeficiency is associated with serious health problems. One of the earliest and the most specific manifestations of vitamin A deficiency is impaired vision, particularly in dim light, also known as night blindness. If the deficiency persists, further eye damage may occur, which can eventually result in total blindness. Other consequences of vitamin A deficiency include impaired immunityand various skin problems. Moreover, the right amounts of vitamin A are extremely important for pregnant and breastfeeding women to support normal child development.The Vitamin D Council considers these levels to be 'normal to high'. These vitamin D levels can be achieved by exposing the skin to adequate sunlight. As a result, it is assumed that these are natural, healthy levels. Your value is between 80 - 100 ng/ml
