Be-Tabs Folic Acid is folic acid, usually 5 mg, from a South African manufacturer. It is taken to prevent neural tube defects in pregnancy, to treat folate deficiency anaemia, and alongside methotrexate. The 5 mg strength is a therapeutic dose, not an everyday supplement.
What is Be Tabs Folic Acid?
Be-Tabs is the manufacturer; folic acid is the medicine. Folic acid is registered in South Africa under several names, and being given a different brand is ordinary substitution.
The strength that matters is 5 mg, which is what most searches are about. That is a high, therapeutic dose — many times the amount in a general multivitamin, where folic acid is typically 200 to 400 micrograms.
Folic acid is the manufactured form of folate (vitamin B9). The body converts it to the active form used to build and repair DNA, divide cells, and produce red blood cells. Requirements rise wherever cells are dividing rapidly — which is why pregnancy and blood production are where it matters most.
Natural folate is found in dark green leafy vegetables, legumes, liver and citrus. Folic acid in supplements and fortified food is absorbed better than natural folate from food, which is why supplementation works even in people eating reasonably well.
South Africa fortifies maize meal and bread flour with folic acid, which has measurably reduced neural tube defects since it began. That fortification is a background contribution, not a substitute for supplementation where it is specifically indicated.
What is Be Tabs Folic Acid commonly used for?
- Preventing neural tube defects in pregnancy — spina bifida and anencephaly. This is its most important use, and the timing is critical (see below).
- Folate deficiency anaemia, where red blood cells are large and immature.
- Alongside methotrexate, taken weekly on a different day, to reduce its side effects — mouth ulcers, nausea and liver effects — without reducing its effectiveness.
- Malabsorption conditions — coeliac disease, inflammatory bowel disease, after bariatric surgery.
- Chronic haemolytic anaemias, including sickle cell disease and thalassaemia, where red cell turnover is high.
- People on anti-epileptic medicines, which deplete folate.
- Alcohol dependence, where deficiency is common.
- Dialysis patients.
The pregnancy timing is the single most important point on this page. The neural tube closes in the first four weeks after conception — often before a pregnancy is recognised. Folic acid must therefore be started before conception, ideally at least a month beforehand, and continued through the first twelve weeks.
Standard dose is 400 mcg daily. The 5 mg dose is used where risk is higher, including:
- A previous pregnancy affected by a neural tube defect
- Diabetes
- Epilepsy medicines, particularly valproate or carbamazepine
- Obesity
- Coeliac disease or malabsorption
- Sickle cell disease or thalassaemia
- A family history of neural tube defects
If any of those apply, ask specifically about the higher dose — this is a common and consequential gap in antenatal care, and the difference is not trivial.
Who commonly looks for Be Tabs Folic Acid and why
- Women who are pregnant or planning pregnancy, by a wide margin.
- Women prescribed 5 mg rather than the standard 400 mcg, wondering why.
- People on methotrexate for rheumatoid arthritis or psoriasis.
- People told they have folate deficiency after a blood test.
- People with sickle cell disease or thalassaemia.
- People on epilepsy medicines.
- People with malabsorption conditions.
- Anyone feeling tired, hoping it is the answer — for whom a blood test is far more useful than a supplement.
What to check on the label before taking Be Tabs Folic Acid
- The strength — 5 mg is very different from 400 mcg (0.4 mg). Confirm you have what was intended.
- Whether other supplements already contain folic acid, including pregnancy multivitamins, so you are not doubling unintentionally.
- Whether your product contains vitamin B12, or whether that has been checked separately — this matters, and the reason is below.
- The manufacturer and expiry date.
- Whether it is a once-daily or once-weekly instruction — with methotrexate it is weekly, and taking it daily by mistake is a recognised error.
Safety, interactions and when to seek professional advice
Folic acid is safe and well tolerated. Side effects are uncommon — occasional nausea, bloating, loss of appetite or a mild rash.
The one genuinely important caution concerns vitamin B12.
Folic acid corrects the anaemia of vitamin B12 deficiency without correcting the deficiency itself. That is dangerous, because B12 deficiency also damages nerves — causing numbness, tingling, unsteadiness, memory problems and, if prolonged, permanent damage. Treating with folic acid alone can mask the blood abnormality while the nerve damage continues undetected.
Vitamin B12 should be checked before starting long-term high-dose folic acid, particularly in older people, vegans, people on metformin or long-term acid-suppressing medicines, and anyone with unexplained anaemia. If you are taking 5 mg long term and B12 has never been checked, ask.
Speak to a doctor or pharmacist before taking it if you:
- Have untreated or unconfirmed vitamin B12 deficiency, or pernicious anaemia.
- Have anaemia that has not been diagnosed. Anaemia needs a cause established, not just a supplement — in adults it can be the first sign of bleeding that needs investigating.
- Take methotrexate — the timing matters, and it is taken on a different day from the methotrexate.
- Take anti-epileptic medicines — folic acid can lower phenytoin levels, and the two need balancing.
- Take sulfasalazine, trimethoprim or cotrimoxazole, which interfere with folate.
- Have a history of cancer, where high-dose folic acid should be discussed with your specialist.
- Have a stent or heart disease, where high-dose combinations have been questioned.
Stop and seek advice for a rash, wheezing or facial swelling, and get emergency help for swelling of the face, lips or tongue or difficulty breathing.
See a doctor rather than self-treating for persistent tiredness, breathlessness on exertion, pallor, numbness or tingling in the hands or feet, or unsteadiness. And if you are planning a pregnancy, start folic acid before you conceive — that is the single most useful thing on this page.

Frequently asked questions
What is Be-Tabs Folic Acid 5 mg used for? Preventing neural tube defects in higher-risk pregnancies, treating folate deficiency anaemia, protecting against methotrexate side effects, and supporting conditions with high red cell turnover.
Why 5 mg instead of 400 mcg? 400 mcg is the standard pregnancy dose. 5 mg is used where risk is higher — previous affected pregnancy, diabetes, epilepsy medicines, obesity, malabsorption, sickle cell disease or thalassaemia.
When should I start it in pregnancy? Before conception, ideally at least a month beforehand, and continue through the first twelve weeks. The neural tube closes in the first four weeks, often before a pregnancy is recognised.
Is Be-Tabs the medicine? No. Be-Tabs is the manufacturer; folic acid is the active ingredient.
Why do I take it with methotrexate? It reduces methotrexate’s side effects without reducing its effectiveness. Take it on a different day from the methotrexate.
Can it hide a vitamin B12 problem? Yes, and this is the main caution. It corrects the anaemia of B12 deficiency while nerve damage continues. Have B12 checked before long-term high-dose use.
Will it help my tiredness? Only if you are deficient. Persistent tiredness needs a blood test rather than a supplement.
Is it safe long term? Generally yes, with B12 checked and a clear reason for continuing. Review it periodically.
