Biocare FolGuard (Folic Acid & B12) – 30 Vegetable Capsules

What Is a Folic Acid and B12 Supplement?

Biocare FolGuard is a folic acid and B12 supplement combining two essential B vitamins in a single, easy-to-swallow vegetable capsule. Folic acid — the synthetic form of folate — and vitamin B12 (cyanocobalamin) are both water-soluble nutrients that your body cannot produce in sufficient quantities on its own. That means you rely entirely on diet or supplementation to meet your daily needs. For many people in the UK, that gap is wider than they realise. If you're looking to support your overall nutritional intake alongside other health products, you'll find Biocare FolGuard listed in our vitamins and supplements collection.

The NHS recommends folic acid supplementation for women who are pregnant or planning a pregnancy, and vitamin B12 is recognised as a nutrient of concern for vegans, vegetarians, and older adults. Together, these two vitamins play a central role in red blood cell formation, DNA synthesis, and normal neurological function. At just £9.86 for 30 capsules, Biocare FolGuard offers a straightforward, plant-friendly way to address both needs at once.

How Does Biocare FolGuard Work in the Body?

Folic acid and vitamin B12 are metabolically interdependent — they work as co-factors in the same biochemical pathways. Here's what happens when you take a capsule:

• Folic acid is converted to its active form (5-methyltetrahydrofolate) in the gut and liver, where it supports DNA replication and cell division.
• Vitamin B12 acts as a co-enzyme that allows folate to enter cells and carry out its functions — without adequate B12, folate becomes "trapped" and cannot be used effectively.
• Together, they facilitate the conversion of homocysteine to methionine, helping to maintain healthy homocysteine levels — elevated homocysteine is associated with cardiovascular risk.
• Both vitamins support the production of healthy red blood cells, reducing the risk of megaloblastic anaemia — a condition where red blood cells are abnormally large and unable to function properly.

This synergistic relationship is why combining both nutrients in one capsule makes clinical sense. Taking folic acid alone without adequate B12 can mask a B12 deficiency, which is why a combined supplement like FolGuard is often a more considered choice.

Who Should Consider Using Biocare FolGuard?

This supplement is suitable for a wide range of people, but it's particularly relevant if you fall into one of the following groups:

• Women planning pregnancy or in early pregnancy — the NHS advises 400 micrograms of folic acid daily from before conception until week 12 of pregnancy to reduce the risk of neural tube defects.
• Vegans and vegetarians — vitamin B12 is found almost exclusively in animal-derived foods, making supplementation important for those following plant-based diets.
• Older adults — B12 absorption declines with age due to reduced stomach acid production, increasing the risk of deficiency.
• People taking certain medicines — drugs such as metformin, proton pump inhibitors, and some antiepileptics can deplete B12 or folate levels over time.

If you're unsure whether this supplement is right for you, speak to your pharmacist or GP before starting. A simple blood test can confirm whether you have a deficiency.

How Does Biocare FolGuard Compare to Taking Separate Supplements?

Is Biocare FolGuard Suitable for Vegans and How Should It Be Stored?

Yes. Biocare FolGuard is encapsulated in a vegetable capsule shell, making it suitable for vegans and vegetarians. There are no animal-derived excipients in the formulation. This is an important consideration for anyone following a plant-based diet — a group for whom a folic acid and B12 supplement is particularly relevant given the near-absence of B12 in plant foods.

Store your capsules below 25°C in a cool, dry place away from direct sunlight and moisture. Keep the container tightly closed and out of reach of children. Do not use after the expiry date printed on the packaging. If you're exploring other plant-friendly health products, take a look at our vegan collection for more options.

This product is a food supplement. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Biocare FolGuard and What Is It Used For?

Biocare FolGuard is a food supplement containing folic acid and vitamin B12 in vegetable capsule form. It is used to help maintain adequate levels of both nutrients in the body — particularly in people whose diet may not provide sufficient amounts. Folic acid contributes to normal blood formation, normal amino acid synthesis, and the reduction of tiredness and fatigue. Vitamin B12 supports the same functions and additionally contributes to normal neurological function and the normal functioning of the immune system, according to established EU nutrition claims.

This supplement is not a licensed medicine and is not intended to diagnose, treat, cure, or prevent any disease. It is designed to complement a balanced diet, not replace it. If you suspect you have a clinical deficiency of either nutrient, please speak to your GP — a blood test will confirm this and your doctor may prescribe a therapeutic dose.

What Do You Need to Know Before Using Biocare FolGuard?

Before starting any new supplement, it's worth checking whether it's appropriate for your circumstances. Please read the following carefully.

Do not use this product if you:

• Are allergic to folic acid, vitamin B12, or any of the capsule excipients
• Have been diagnosed with Leber's disease (a hereditary optic nerve condition) — high-dose B12 may worsen this condition
• Have a known cobalt allergy

Speak to your doctor or pharmacist before use if you:

• Are pregnant or breastfeeding — folic acid is recommended in pregnancy but your doctor should advise on the correct dose for your situation
• Have pernicious anaemia — oral B12 supplements may not be adequately absorbed without intrinsic factor; injections may be required
• Have polycythaemia vera or any other blood disorder
• Have kidney disease

Known drug interactions — inform your pharmacist if you are taking:

• Methotrexate — folic acid can reduce its efficacy in some conditions; your doctor must advise
• Antiepileptic medicines (e.g. phenytoin, carbamazepine) — folic acid may affect seizure control
• Metformin — long-term use can reduce B12 absorption
• Proton pump inhibitors (e.g. omeprazole) — may reduce B12 absorption over time
• Chloramphenicol — may interfere with the haematological response to B12

How Should You Use Biocare FolGuard?

Always follow the label instructions or the advice of your pharmacist. The steps below reflect standard guidance for this type of supplement.

1. Take one vegetable capsule daily.
2. Swallow whole with a full glass of water.
3. Take with or after a meal to minimise any risk of stomach upset.
4. Try to take it at the same time each day to maintain consistency.
5. Do not exceed the recommended daily dose unless directed by a healthcare professional.

This supplement is not recommended for children under 18 unless specifically advised by a healthcare professional. Women who have previously had a pregnancy affected by a neural tube defect should speak to their GP, as a higher dose of folic acid (5 mg) may be recommended — this is only available on prescription.

What Are the Possible Side Effects of Biocare FolGuard?

At the doses found in food supplements, folic acid and vitamin B12 are generally very well tolerated. Serious side effects are rare. That said, it's important to be aware of what to look out for. If you're managing other health conditions alongside supplementation, our women's health collection includes additional products that may be relevant to your care.

Common side effects (may affect some users):

• Mild nausea, particularly if taken on an empty stomach
• Mild gastrointestinal discomfort or bloating
• Temporary changes in urine colour (B12 can cause bright yellow urine — this is harmless)

Less common side effects (rare at supplement doses):

• Skin reactions such as rash or itching — may indicate sensitivity to an excipient
• Headache
• Diarrhoea
• Allergic reaction — seek immediate medical attention if you experience swelling of the face, lips, or throat, or difficulty breathing

High-dose folic acid (above 1 mg/day) taken long-term may mask the symptoms of vitamin B12 deficiency, which is one reason why a combined supplement is preferable to folic acid alone in many cases.

How Should You Store Biocare FolGuard?

• Store below 25°C in a cool, dry place
• Keep away from direct sunlight and sources of heat or moisture
• Keep the lid tightly closed after each use
• Keep out of the sight and reach of children
• Do not use after the expiry date printed on the packaging
• Do not store in the bathroom or near a sink — humidity can degrade the capsules

If you have any unused capsules after the expiry date, do not dispose of them in household waste or down the sink. Take them to your local pharmacy for safe disposal. You can find further guidance on supplement storage and safe disposal through the NHS. For other health essentials you may need to store safely at home, browse our first aid collection.
