Folate is vitamin B9 and contributes to normal homocysteine metabolism. Folic acid and methylfolate are different forms within this vitamin family. This guide explains the names, the 500 µg folate portion in B-Complex and the practical points to consider when choosing a supplement.
Folate, folic acid and 5-MTHF: the names
Folate is the umbrella term. It includes the forms naturally present in foods and those used in supplements. Folic acid is an oxidised form widely used in supplements and fortified foods. 5-MTHF, also called methylfolate, is another supplemental form and a main circulating form in the body.
MTHFR and the processing of folic acid
CDC states that people with common MTHFR variants can process folic acid. Enzyme activity may vary, and advice about folate form and amount should take your overall circumstances into account. A clinician can interpret a genetic result together with your diet, medical history and reason for supplementation.
What distinguishes methylfolate?
5-MTHF, or methylfolate, is a main circulating form of folate in the body and is also used in supplements. B-Complex provides it as Extrafolate-S®, with a declared amount of 500 µg per capsule. The named form and source help you compare the composition alongside the rest of the formula and your intended use.
What about folate in food?
Leafy green vegetables, beans, lentils and other foods contribute folate. Fortified foods vary by country and product, so check the label rather than assuming every flour or breakfast cereal contains it. The EU reference used on a supplement label is not an individual dietary prescription; do not mix it up with US dietary folate equivalent figures.
Planning a pregnancy is a separate decision
Seek timely, specific folic-acid advice from a clinician or your national health service when planning a pregnancy. CDC guidance on folic acid still applies to people with common MTHFR variants; it should not be rewritten as a recommendation to replace folic acid with any methylfolate product. BMPHARMA B-Complex is not a prenatal formula: its label excludes pregnancy and breastfeeding.
When to seek advice before adding folate
Persistent symptoms need assessment rather than a guess that folate is low. Folate and B12 problems can overlap, and folic acid can improve the blood picture of B12 deficiency without resolving its neurological effects. If you take methotrexate, anti-seizure medicines or other regular treatment, ask the prescriber about folate; do not change prescribed medicine or a prescribed folate schedule yourself.
What one B-Complex capsule contains
| Nutrient | Amount and source |
|---|---|
| Folate | 500 µg — 250% NRV; 5-MTHF as Extrafolate-S® |
| Vitamin B12 | 100 µg — 4000% NRV; methylcobalamin |
B-Complex combines all eight B vitamins with choline, inositol and PABA as additional ingredients. The vegan pack contains 60 HPMC capsules; one capsule daily provides 60 daily portions. The folate and B12 amounts in the table are expressed in micrograms (µg).
One authorised nutrient statement relevant to this formula is:
Folate contributes to normal homocysteine metabolism.
B-Complex brings eight B vitamins together in one daily capsule. Compare this combined approach with a targeted nutrient supplement according to your needs. Review overlapping supplements and their total amounts, including B6; seek an individual plan if a deficiency has been diagnosed.

Do not exceed one capsule daily. Not suitable for children, pregnant or breastfeeding women, or anyone allergic to an ingredient. Discuss regular medicines and medical conditions with a doctor or pharmacist. Tell the laboratory that the product contains biotin before blood tests. Keep out of reach of young children. A food supplement does not replace a varied, balanced diet and a healthy lifestyle.
Frequently asked questions
Is folate the same as vitamin B9?
Yes. Folate is the name for the vitamin B9 family, which includes folic acid and 5-MTHF as different forms.
Does a high homocysteine result prove folate deficiency?
No. It can be influenced by B12 status and other factors. Have the result interpreted in context rather than using it to choose a high-dose folate product.
Can this B-Complex replace a prenatal supplement?
No. Its label excludes pregnancy and breastfeeding. Seek a specific plan suited to that stage.
