Vitamin D
Vitamin D is a fat-soluble vitamin. Sunlight is the most important source of vitamin D. The body can produce vitamin D itself under the influence of sunlight in the skin, but you can also get it through food. How much vitamin D do you need, how do you get enough and what else do you need to know about it?

What does vitamin D do in your body?
Your body can produce vitamin D through sunlight, but it's also found in food. Vitamin D is a fat-soluble vitamin: this means you can also find it in the fat of some foods. Your body can store vitamin D and use it when needed.
How do you know if you have a vitamin D deficiency?
A vitamin D deficiency can eventually lead to bone loss or osteoporosis and/or muscle weakness.
These symptoms may be attributed to other deficiencies or problems, so always consult a doctor if you experience them persistently or are concerned.
Which foods contain vitamin D?
Vitamin D is best absorbed from the sun, but you can also get it from food. Vitamin D is found in oily fish, such as rainbow trout, herring, salmon, mackerel, and organ meats. Meat and eggs also provide vitamin D, but less so than oily fish. Vitamin D is also added to margarine, low-fat margarine, and baked goods.
How much vitamin D should I take?
Your body doesn't produce vitamin D. You get it from sunlight (which provides two-thirds of your daily needs) and food. The recommended daily allowance is between 10 and 20 mcg, with a maximum daily allowance of 100 mcg.
One capsule of Guud Flow contains 25 mcg of vitamin D.
How long can I take vitamin D?
How long and whether you can take vitamin D depends on your individual needs and personal situation. Make sure you get enough outdoor exercise, get enough vitamin D through your diet, and supplement your diet with a supplement if necessary. Consult a doctor if you suspect a vitamin D deficiency and want personalized advice.
