Clinically Proven Benefits
Five active B-vitamins at doses used in published research. Vitamin B12 contributes to the normal functioning of the nervous system and to the reduction of tiredness and fatigue. B12, B6, B1 and niacin contribute to normal energy-yielding metabolism. B6 and folate contribute to normal psychological function.
Why a liquid instead of a tablet?
It is held under the tongue for about a minute, which lets it absorb directly. Tablets have to survive the stomach first, and that route gets less reliable with age and with some long-term medications.
What does it taste like?
Sweet rather than bitter, which is not what people expect from a B vitamin. It is sweetened with maltitol rather than sugar. Hold it under the tongue for the minute, then follow it with juice or coffee if you prefer.
When will I notice anything?
B vitamins work by rebuilding a level rather than by hitting you on the day, so give it a few weeks of daily use. That is exactly why the guarantee runs ninety days and not fourteen.
Can I take it with my other medication?
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.

Real Benefits. Backed by Research.
Five B vitamins in one dropper, in the forms your body can use straight away.
Nerve Comfort
Steady, comfortable days.
Nerves need B12 to stay in good working order. SEFA uses methylcobalamin, the form your body can use straight away, at 5,000 mcg. B12 and niacin contribute to the normal function of the nervous system.
Calm Evenings
Wind down without the wired feeling.
B6 helps your body make the chemicals that settle you down at night. Get enough of it and evenings feel less wired. Vitamin B6 and folate contribute to normal psychological function.
Energy Without the Crash
Steady fuel, all day.
Your cells turn food into energy, and they need B vitamins to do it. That is why this feels like steady fuel rather than a coffee hit. B12, B6, thiamine and niacin contribute to normal energy-yielding metabolism.
Mental Clarity
Focused, not foggy.
Low B12 is a common reason people feel foggy after 50. Topping it back up is often what lifts the fog. Vitamin B6 and folate contribute to normal psychological function.
Five Vitamins, One Dropper
Five B vitamins in their active forms, held under the tongue for a minute so they absorb straight into the bloodstream.
The One That Works With It
B9Folate and B12 work as a pair. Folate contributes to the reduction of tiredness and fatigue.
Signal And Mood
B6Pyridoxine helps build the neurotransmitters that carry signals between nerve cells. B6 contributes to normal psychological function.
Turning Food Into Fuel
B1Thiamine converts what you eat into usable cellular energy. B1 contributes to normal energy-yielding metabolism.
Nerves And Energy
B3Niacin contributes to normal energy-yielding metabolism and to the normal function of the nervous system.

5 Reasons Why SEFA Is Different From Everything You've Tried
Reason 1
Real Doses, Backed by Research
5,000 mcg of methylcobalamin and a complete B-complex in every dropper. Not a pinch for the label, the amounts studies actually use when they measure nerve support.
Reason 2
It Actually Gets In
Here is what nobody told you: after 50 your stomach makes far less acid, and some long-term medications block B12 uptake on top of that. The pills dissolved, they just never reached you. SEFA absorbs under the tongue, straight in, gut problem skipped.
Reason 3
The Form The Research Used
Cheap B12 is cyanocobalamin, a synthetic form built in a lab and priced to match, usually at 1,000 mcg. We start with methylcobalamin. It is a licensed medicine in Japan, it is the form most of the published B12 research was actually run on, and we use it at 5,000 mcg.
Reason 4
The Full Formula
5,000 mcg of B12 as methylcobalamin, the form the research uses. B6 and thiamine at 200% of your daily reference, niacin and folate at 100%. We name the actual form of each vitamin, not just the letter, because the form is what decides whether it works. No alcohol, no gelatin, sweetened with maltitol rather than sugar.
Reason 5
Built to Compound
Nerves and nutrient levels rebuild over weeks and months, which is exactly why a daily habit beats a burst. SEFA is a few drops with your morning coffee, quietly compounding while you stop thinking about it. The guarantee runs ninety days because that is long enough for it to show.

Paul N.
I experience numbness in all four limbs … I love these B12 drops. They absorb rapidly when applied under the tongue as directed. I have difficulty swallowing even medium size pills, so it is a relief to get a full dose without having to get yet another dry pill down my throat. Within days of starting to take them once a day, I experienced a definite upswing in energy. Fatigue began to fade away.

I love this B12. It is so easy to take, the glass dropper has the levels on it, so no under or over fill. I believe this product is safe and has been carefully and safely crafted.

I've tried lots of B12 supplements over the years … It's got a nice sour berry taste and it is insanely effective. Within 30 minutes of taking this I feel like I've already had a cup of coffee. I am much more awake during the day and able to sleep better at night. I had been experiencing lots of joint and muscle pains, they are almost completely gone now.

Absolutely love this B12 liquid drops! It's super convenient, absorbs fast, and I can really feel the energy boost. No more swallowing pills, and the taste is surprisingly pleasant.

I've been taking this particular B12 supplement for several years after being diagnosed with a B12 deficiency caused anemia … I was experiencing fatigue, shortness of breath, and dizzy spells on the regular. I was tested again within a month after starting this product and everything was back to normal and I started feeling much better.

Increased energy noticed upon 1st day of use. So easy to take and tastes great! My husband and I both take it and my 75 year old mother and stepdad are both taking it now too. We all love it!

I bought this for my wife because her last blood test showed extremely low levels, almost nothing. Her most recent test after a month of use has her levels returning. Her doctor loves the product she is using.

Take it every morning and I put it under my tongue, and it just slides right down. It doesn't taste bad. It tastes really good. I've noticed an increase in energy. So far it seems like it's helping. I recommend it.

Based on customer experienceFREQUENTLY ASKED QUESTIONS
Questions, answered properly
How long does delivery take?
8 to 10 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.
Will I be charged customs or VAT?
Orders arriving in Ireland may attract Irish VAT and a customs handling fee, set by the Irish authorities rather than by us. We declare every parcel honestly at its real value, which is the only way that ends well for you.
How can I pay?
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.
Is this a subscription?
No. You pay once, for the bottles you choose, and nothing else is ever charged to your card. There is no plan to cancel and no repeat order to forget about.
How many bottles should I order?
One bottle is forty days. B vitamins work by rebuilding a level rather than by hitting you on the day, so most people want a longer run than that. Two bottles is eighty days, three is a hundred and twenty, and the price per bottle drops each time you add one. The ninety day guarantee covers whichever you pick.
What if it does not work for me?
Take it daily for ninety days. If you are not glad you bought it, take advantage of our ninety day money back guarantee and we refund you in full. No posting back a half-used bottle, no explaining yourself. That covers the taste as much as anything else.
