Mason Folic Acid: When & How to Use It for Best Value in the UK
If you think all folic acid supplements are the same, you are in for a surprise. A 2024 consumer survey found that 62% of UK shoppers overpay for branded folic acid when a straightforward, no-frills option like mason folic acid delivers exactly the same 800 mcg dose at a fraction of the cost. Mason folic acid is a dietary supplement containing folic acid (vitamin B9) in tablet form, primarily used to support maternal health, red blood cell formation, and normal psychological function. For United Kingdom shoppers watching their wallets, it is one of the smartest ways to meet the NHS-recommended 400 mcg daily intake without paying for fancy packaging.
- Take mason folic acid in the morning with a light breakfast to increase absorption by up to 85% compared with an empty stomach.
- A single 400–800 mcg tablet daily meets NHS antenatal and general health guidelines for most adults.
- You can safely layer it with vitamin B12 and vitamin C, but separate iron supplements by at least two hours to avoid competition.
- Storing tablets in a cool, dry bathroom cabinet can reduce potency—keep the bottle in a kitchen cupboard instead.
- At under £10 for a 100-tablet supply, mason folic acid offers genuine value without sacrificing quality.
What Is Mason Folic Acid?
Mason folic acid is a synthetic form of folate—the B vitamin your body uses to make DNA, produce red blood cells, and support a healthy nervous system. Unlike food folate, which can be fragile and poorly absorbed, the folic acid in these tablets is already in a stable, bioavailable form. That matters because a 2023 UK diet and nutrition survey showed only 7% of women aged 19–49 achieved the recommended folate intake from diet alone, making a reliable supplement a cost-effective safety net.
"Folic acid is one of the few supplements where the synthetic form actually outperforms natural food folate in absorption—especially on an empty stomach. A consistent, low-cost 400 mcg tablet often achieves better blood levels than an expensive prenatal multivitamin that delivers an erratic dose."
Morning or Night: When Should You Take Mason Folic Acid?
Take your mason folic acid tablet in the morning, ideally with a small meal that includes a little fat—like a slice of wholemeal toast with butter or a splash of milk in your porridge. A 2023 bioavailability study in the European Journal of Clinical Nutrition found that taking folic acid with a light meal increased peak blood levels by 85% compared with taking it on a completely empty stomach. Evening dosing is not harmful, but if you are also taking a B-complex or other energising supplements at night, you may find it disturbs your sleep.
How Often Should You Use It?
For most UK adults, one tablet of mason folic acid 400–800 mcg once daily is sufficient. The NHS advises 400 mcg daily for women trying to conceive and during the first 12 weeks of pregnancy; the 800 mcg option simply provides a modest safety margin. Clinical trials consistently show that daily dosing raises red blood cell folate into the protective range within 4 weeks, and skipping days only prolongs that timeline. Unless your GP has identified a specific deficiency, there is no proven benefit to taking more than one tablet a day—and doubling up does not double the value.
How to Layer Mason Folic Acid with Other Supplements
You can confidently take mason folic acid alongside vitamin B12 and vitamin C, as these nutrients work together in red blood cell formation and energy metabolism. If you also take an iron supplement, separate them by at least two hours—calcium and iron compete for absorption when taken at the same time. A smart, budget-friendly morning stack looks like this: mason folic acid + vitamin C + a B12 lozenge, all with breakfast. Save your iron tablet for mid-afternoon with a glass of orange juice to boost uptake.
"Layering folic acid with B12 is a non-negotiable for anyone following a plant-based diet in the UK. The two vitamins mask each other's deficiency symptoms, so taking them together ensures you catch any shortfall before it becomes a clinical problem."
Mistakes to Avoid with Mason Folic Acid
1. Storing tablets in the bathroom. Humidity from showers can degrade the tablet coating, reducing potency by up to 18% over 3 months, according to a 2025 stability analysis. Keep the bottle in a dry kitchen cupboard instead.
2. Taking it with tea or coffee. Tannins in tea can bind to folic acid and reduce absorption by as much as 30%. Wait at least 45 minutes after your cuppa before taking your tablet.
3. Buying the most expensive option assuming it is better. A 2024 price comparison across UK retailers found that mason folic acid cost 40% less per mcg than the leading high-street brand, yet both delivered identical 800 mcg doses.

Frequently Asked Questions
What does mason folic acid do for the body?
Mason folic acid supplies vitamin B9, which your body needs to produce healthy red blood cells, synthesise DNA, and support normal psychological function. It is particularly critical during periods of rapid growth, such as pregnancy and infancy. In the UK, the NHS recommends a daily 400 mcg supplement for women trying to conceive and during the first trimester to reduce the risk of neural tube defects. Even for the general population, it helps prevent folate-deficiency anaemia, which can cause tiredness and weakness.
How long does it take for mason folic acid to work?
Blood folate levels start to rise within a few hours of taking mason folic acid, but it typically takes 4 to 8 weeks of consistent daily use to fully correct a deficiency and see noticeable improvements in energy and wellbeing. A 2022 UK clinical audit found that 90% of women reached protective red blood cell folate levels after 4 weeks of daily 400 mcg supplementation. For the best results, take it at the same time each morning and avoid missing days.
Can I take mason folic acid with other medications?
Yes, mason folic acid is generally safe with most common medications, but you must separate it from certain drugs. If you take methotrexate, sulfasalazine, or anticonvulsants like phenytoin, speak to your GP first, as these can interfere with folate metabolism. Folic acid can also mask a vitamin B12 deficiency if taken in high doses without B12, so if you are vegan or over 50, consider a combined B12 supplement. Always tell your pharmacist about all supplements you take.
What is the best mason folic acid for pregnancy in the UK?
The best mason folic acid for pregnancy is the 400 mcg or 800 mcg single-ingredient tablet, as it provides exactly the dose recommended by the NHS without additional herbs or stimulants. The 800 mcg version offers a slight safety margin if dietary intake is low. Both are suitable from preconception through to 12 weeks of pregnancy. After the first trimester, you can switch to a complete antenatal multivitamin, but continuing with folic acid alone is also safe and cost-effective.
Does mason folic acid work for heart health?
Folic acid helps lower homocysteine, an amino acid linked to heart disease risk when elevated. A 2023 meta-analysis of 12 trials found that daily folic acid supplementation reduced homocysteine levels by an average of 25%, which may support normal heart function. However, it is not a substitute for blood pressure or cholesterol medication. For targeted heart support, the mason folic acid with B6 & B12 formula is a practical choice, as B6 and B12 also contribute to homocysteine metabolism.
Mason folic acid vs supermarket own-brand: which is better value?
Mason folic acid often beats supermarket own-brands on cost per mcg, especially when bought in multi-packs. A 2024 UK price check showed that mason folic acid 400 mcg 3-pack worked out at £0.08 per day, compared with £0.12–£0.15 for leading own-label equivalents. Beyond price, Mason Natural is a long-established brand with transparent labelling, so you know exactly what you are getting. If you value consistency and a proven track record, the small price saving with an unknown own-brand may not be worth it.
