Everything about Folsaeure
All articles on Folsaeure — from dosage to timing, explained clearly.
Folic acid: too much of a good thing — the upper limit and unmetabolized folic acid
There is no upper limit for folate from food. For synthetic folic acid there is: 1,000 µg a day for adults. Why this limit exists has little to do with the vitamin itself.
MTHFR: what is established about the gene variant — and what is not
About one in ten Europeans carries the C677T variant in duplicate. What follows from it is well studied — and considerably less dramatic than the trade in genetic tests suggests.
Spotting a folate deficiency: serum folate, red blood cell folate and what sets them apart
One value swings with the last meal, the other reflects months. Measure the wrong one and you get a number that does not fit the question — and may miss the actual problem.
Folic acid in foods: where there is plenty — and what cooking takes away
Leafy greens and pulses head the tables. What matters, though, is how much survives storage, soaking and cooking — and how much of that the body absorbs.
Folic acid or folate: where the difference lies
Folate is the natural form, folic acid the synthetic one — and 400 µg from a tablet is not 400 µg from a salad. What folate equivalents mean.
Folic acid and vitamin B12: the overlooked gap
Folic acid does not cause a B12 deficiency — it makes its most conspicuous sign disappear. Who should settle the B12 question first, and which values still say something afterwards.
Folic acid daily requirement: 200, 300 or 400 µg?
The label says 200 µg, the DGE names 300, preparations carry 400 or 800. All three figures are correct — they simply answer different questions.
Folic acid in pregnancy: 400 µg, from when
400 µg folic acid a day — beginning four weeks before conception. Why starting at the positive test is too late, and what the authorised claim says word for word.
Buying folic acid: comparing µg, form and label
Two packs with the same µg figure are not the same thing. What has to be on the label, which folate sources are permitted and how to compare prices.
Taking folic acid: timing, duration, combination products
On an empty stomach or with food, morning or evening, for how long — and what counts towards the total in a combination product. The answers with the figures from the DGE, the BfR and the EFSA.
