Frequently Asked Questions
Why choose Barefoot Nutrition B12 Complete?
+

What is Barefoot Nutrition B12 Complete?
+
A high-strength methylated B12 supplement in the UK, providing 1000mcg methylcobalamin per capsule, combined with methylfolate and D-biotin.
Designed to support how the body absorbs and uses B12, not just intake.
What are the benefits of Barefoot Nutrition B12 Complete?
+
Supports:
- Energy levels and reduction of fatigue
- Normal nervous system function
- Mental clarity and focus
- Red blood cell formation
- Normal homocysteine metabolism
Why use methylated B12 and methylfolate?
+
We use active forms the body can use immediately:
- Methylcobalamin (B12) – no conversion required
- Methylfolate (L-5-MTHF) – bypasses folic acid conversion issues
Around 20% of people have an MTHFR variation, meaning standard folic acid may not be effectively used.
Why combine B12, folate and biotin?
+
They work together in the same pathways:
- Folate helps activate and recycle B12
- B12 and folate support methylation and red blood cell production
- Biotin supports energy metabolism and enzyme function
Without these cofactors, B12 alone may not be used as effectively.
Do I have low B12? (Common symptoms)
+
You may consider B12 support if you experience:
- Low energy or fatigue
- Brain fog or poor concentration
- Pins and needles
- Low mood
Higher risk groups include those on vegan or plant-based diets.

Excellent RDA of all the vitamins and minerals and the right types e.g B12 is in cobalamin form and capsule has no nasty bulking e.g calcium carbonate which hardens the arteries. Best swallow with a teaspoon of fat/cube of cheese to help the capsule do down. Thank you for using a glass jar and for leaving out all the toot that other companies sell. This is very good value and you do feel better. I am on my second order!
