A 60 ml amber glass dropper bottle of SEFA B-Complex Drops. Five B vitamins plus added vitamin C, in a glycerin base. One and a half millilitres a day, which makes a bottle forty days of use.

Methylcobalamin at 5,000 mcg, the form the research used, alongside folate, pyridoxine (B6), thiamine (B1), niacin and added vitamin C. It sits in a glycerin base, lightly sweetened with maltitol so it actually goes down easily. No gelatin. No alcohol.

Two reasons, and both are printed on the bottle. Cyanocobalamin is the synthetic form almost everything on the shelf uses, and it is usually 1,000 mcg. Methylcobalamin is a licensed medicine in Japan, and it is the form most of the published B12 research was actually run on, which is not a coincidence. We use it at 5,000 mcg.

No gelatin, which matters more than it sounds: a great deal of B12 is sold as a gelatin softgel. No alcohol either, which is unusual for a sublingual liquid. No gluten, no soy. The full list is on the product page and printed on the bottle.

One and a half droppers under your tongue, once a day. Hold it there for about sixty seconds, then swallow. That is the whole routine. Ten seconds of actual effort, with or without food.

Sweet, not bitter. That tends to surprise people, because most B vitamins are unpleasant enough that you brace for it. It is lightly sweetened with maltitol, it is gone in about a second, and plenty of customers say it is the first supplement they have not had to talk themselves into taking.

B vitamins work by rebuilding a level rather than by hitting you on the day, so this is a daily habit, not a one-off. Most people give it a few weeks before they take stock. That is exactly why the guarantee runs ninety days and not fourteen, so you get a proper run at it, at our risk rather than yours.

B vitamins are water soluble and among the most widely taken supplements there are. That said, if you are on prescription medication, pregnant or breastfeeding, have a quick word with your doctor or pharmacist first.

12 to 25 days, and your order is prepared within 1 to 2 business days of being placed. We ship direct from our production partner rather than paying for local warehousing, and that is exactly what keeps the price where it is. Tracking reaches you by email the moment it moves.

Take it daily for ninety days. If you are not glad you bought it, email us and we refund you. No posting back a half-used bottle, no explaining yourself. That covers the taste as much as anything else.

Orders arriving in Iceland may attract Icelandic VAT and a postal handling fee, set by the Icelandic authorities rather than by us. We declare every parcel honestly at its real value, which is the only way that ends well for you.

Credit and debit cards, plus Apple Pay and Google Pay. Apple Pay only appears in Safari and on iPhone, so if you cannot see it, that is why.
