About Us

SEFA exists because of a gap that is easy to miss. Most people who feel flat, foggy and tired are not short of vitamin B12 on paper. Their blood test comes back inside the normal range and the conversation stops there. What the test does not show is how much of it is actually reaching them.

Two things get in the way. Almost all cheap B12 is cyanocobalamin, a synthetic form the body has to convert before it can use it, and that conversion gets less efficient with age and with some long-term medications. On top of that, absorption in the gut depends on stomach acid, and the body makes less of it as the years go on. So the tablet dissolves and much of it simply passes through.

We built SEFA around both problems. It uses methylcobalamin, the form that is already active when it arrives, and it goes under the tongue rather than through the stomach. Five B vitamins, one dropper, ten seconds in the morning.

What we will not do

We will not tell you this cures anything. It is a food supplement, not a medicine, and any seller who tells you otherwise is one to walk away from. The claims we make about these vitamins are the ones authorised under EU law, and we are happy to be held to exactly those and nothing more.

We will not invent reviews. If you see reviews on this site, a real person wrote them, and where they are reviews of this product sold by somebody else, we say so plainly.

We will not pretend the delivery is faster than it is. We ship direct from our production partner, which takes 12 to 25 days. That is the trade that keeps the price where it is.

The guarantee

Ninety days. B vitamins rebuild a level over weeks rather than working on the day, so anything shorter would not be a fair test. Take it daily, and if you are not glad you bought it, email us and we refund you. Nothing to post back.
