Hydroxocobalamin is a form of vitamin B12. It is the form the body converts and stores, rather than one that is used straight away.
Vitamin B12 helps the body release energy from food, make red blood cells and keep the nervous system healthy. 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 provides hydroxocobalamin in purified water, with no other ingredients. Because the body releases it slowly, it is the usual choice for keeping levels up between B12 injections and for those who have found methylcobalamin unsuitable.

Both are forms of vitamin B12. Hydroxocobalamin is retained longer and the body converts it into the active forms as needed; methylcobalamin is already an active form. People who find methylcobalamin overstimulating often prefer hydroxocobalamin.
Hydroxocobalamin is retained in the body longer than cyanocobalamin, which is why many people prefer it for daily use.
Each drop provides 98mcg of hydroxocobalamin (3920% NRV). Take one drop daily in water, on the tongue, or held under the tongue for 30 seconds, with food.
Hydroxocobalamin injections are prescription-only in the UK and are given for diagnosed B12 deficiency. These drops are a food supplement taken by mouth or held under the tongue, providing 98mcg of hydroxocobalamin per drop. If you have been prescribed injections, keep to your prescription and speak to your GP before changing anything.
People who find methylcobalamin overstimulating, people who have had hydroxocobalamin injections and want the same form by mouth with their GP's agreement, vegetarians and vegans, and anyone building B12 stores steadily rather than quickly.
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.
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.
