“A lot of people aren’t getting enough vitamin B12. It’s affecting 6% of people under 60. And 20% of people over 60.

In the late stages, a vitamin B12 deficiency can cause problems like anaemia and nerve problems.

Our tablets contain methylcobalamin — the active form of B12 — which is a safe and effective way to boost your levels.”
