★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie
Cyanocobalamin is the form of vitamin B12 used in most studies and most standard supplements. It is stable in liquid and the body converts it to the active forms after absorption.
Vitamin B12 is needed for making red blood cells, for the nervous system and for releasing energy from food, and it contributes to the reduction of tiredness and fatigue. It is found almost only in animal foods, so those on a vegan diet and anyone whose levels have tested low often need a supplement.
This liquid contains two ingredients, purified water and cyanocobalamin. It is often chosen by people who have used this form before and want to continue with it in a dose they can adjust.

Frequently asked questions
What is cyanocobalamin and when is it the right choice?
Cyanocobalamin is the most stable and most researched form of B12. The body converts it to the active forms after absorption. It suits general daily supplementation at the lowest cost per serving.
How does it compare with methylcobalamin and hydroxocobalamin?
Methylcobalamin and adenosylcobalamin are active forms used directly; hydroxocobalamin is retained longest. Cyanocobalamin requires conversion but is exceptionally stable and well proven in research.
How much B12 is in each drop?
98mcg per drop (3920% NRV), one drop daily. Around 1351 drops per 100ml bottle.
Is cyanocobalamin suitable for vegans?
Yes. The only ingredients are purified water and cyanocobalamin, suitable for vegans and vegetarians.
Who is cyanocobalamin best for?
People who want the standard form of B12 at the lowest cost for everyday maintenance, people who have been told to take oral B12 and want the tablet form as drops, and vegetarians and vegans. People who convert poorly often choose an active form or TRI-B12 instead.
How long does cyanocobalamin take to work?
Blood levels rise within days of starting. Tiredness usually eases over two to six weeks. Nerve-related symptoms take months and need a GP. If you started because of a low result, retest after eight to twelve weeks.
Why drops rather than tablets?
Drops let the amount be adjusted one drop at a time, and they suit anyone who cannot swallow tablets. Tablets need binders and a coating to hold their shape; this liquid contains only the active ingredient and its carrier.
