What is a low vitamin D level?

A vitamin D level under 75 nmol/l (30 ng/ml) is considered too low. Below 50 nmol/l (20 ng/ml), there is a severe deficiency, and between 50–75 nmol/l, a mild deficiency is present. An optimal level is between 100 and 150 nmol/l (40–60 ng/ml).

Is there a link between vitamin B 12 deficiency and weight gain?

Vitamin B12 deficiency can have various effects on the body, but there is no scientific evidence of a direct link between B12 deficiency and weight gain.

What vitamin is missing in the event of hair loss?

A lack of biotin, zinc, iron or vitamin D can cause or increase hair loss. An under-supply of sulphur-containing amino acids can also impair hair production.

Which form of vitamin C is ideal for skin and beauty?

If you want to provide your skin and beauty with vitamin C in a targeted manner, Ester-C® is a good choice. This form is not only well absorbed, but also remains available in the tissue for longer – and contributes to normal collagen formation. The accompanying plant substances can also round off the antioxidant cell protection effect. Tip: BIOGENA AESTHETICS MiraSkin+ Superior is even more targeted: here, vitamin C is part of a modern and complex formulation that has been specifically developed for skin care.

Which form of vitamin B12 is most effective?

High-dose capsules typically contain especially pure vitamin B12. The most effective forms of vitamin B12 are methylcobalamin and adenosylcobalamin – the body can absorb and utilize these natural substances most efficiently.

What are the symptoms of vitamin B12 deficiency?

The most common symptoms of vitamin B12 deficiency include fatigue, weakness, difficulty concentrating, dizziness and headaches. If vitamin B12 deficiency is left untreated for a long time, it can damage the nerves and cause symptoms such as numbness, tingling or muscle weakness.

What helps quickly with vitamin B 12 deficiency?

In cases of acute vitamin B12 deficiency, injections or high-dose vitamin B12 capsules can help to quickly compensate for the deficiency. Eating foods rich in vitamin B12, such as meat, fish, eggs and dairy products, also supports vitamin B12 supply.

Vitamin D for babies

Should you also give babies vitamin D in summer?

How much Vitamin A should I take per day?

The recommended daily dose of vitamin A is 850 μg retinol equivalent (RE) for adult men and 700 μg RE for women. Pregnant and breastfeeding women have an increased need, while children and adolescents require between 300 and 950 μg RE, depending on age and gender. These amounts can be covered by a balanced diet and, if necessary, by additional dietary supplements. Ideally consult your doctor about a vitamin A dose that is right for you.

What is the best dosage form of vitamin B12?
