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.
What Customers Are Saying About This Product
4.5 out of 5 · 7,000+ five-star reviews
“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'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.”
“I've suffered from brain fog for over a year … I don't know why I was so surprised to find it has helped. Immensely. And within a week. I can now think clearly despite an incredibly busy and highly pressured day-to-day lifestyle without thinking of taking a siesta mid-day. Truly remarkable difference for me. Taste is cherry, actually quite yummy.”
“As I approach the age of 61, I consistently find myself feeling lethargic with that mental fog glooming over me … I immediately took a daily dose, which tastes like berries, and lay down for my daily afternoon nap. To my surprise, not only did I not fall asleep, I arose within 2 hours wanting to go ride my bicycle. This is a first for me!”
“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.”
“I had really bad neuropathy. I started taking this vitamin B product and my neuropathy stopped very quickly almost right away. It's easy to use it. Taste great and it's far above my expectations … my numbers are great when I get blood work. The value is wonderful for the money and my body easily absorbs it.”
“I have been on a GLP1 for over a year, my physician recommended taking B12. I had been taking a cheap gummy variety and noticed zero effects … I am stunned! I feel good, I have steady, calm, focused energy. I feel motivated and not constantly fatigued, which is a huge change for me.”
“I take medication that makes me drowsy. This really helps me stay alert. I had my 90 year old mother try it because she was complaining of being so sleepy during the day. She said it helped so much that I ordered her some. We both have more energy and are more alert.”
“At 72 yrs old...these B12 liquid Drops are great...burst of energy immediately...but the fabulous part is it took care of the neuropathy in my legs … my legs circulation improved, especially at night when you are trying to relax. Highly recommend”
“I love the way I've been feeling after taking this! I have less fatigue and noticed my energy levels are so much higher. It also really helps my mood, I don't have irritability through the day. I take it in the morning and feel way more alert.”
“This stuff is great. I knew the benefits of B12 but didn't want to take shots or pills. This is so easy to take and my husband and I have already seen benefits. Legs are stronger, no more leg cramps at night, just really noticeable benefits.”
“The taste reminds me of cherry cough syrup. Easy to take, not hard on my sensitive stomach. Love the fact that I don't have to gag on huge pills and have my body try to break down nasty capsules with unnecessary ingredients anymore.”
“I have been using this product for the past 2 years … I had been suffering with severe anemia, nothing seemed to work until I started using this product … I am seventy two years old and I feel better than I've ever felt in my life.”
“I didn't realize I was deficient in b12 until I started taking this and felt the difference … I was blown away at how much better I felt once I started taking it regularly. Clearer mind and more energy. Highly highly recommend.”
“Best natural vitamins, you can really feel it. Gives you energy when needed. Can make you feel relaxed and collected, thinking and doing things better. Better sleep. Overall it's exactly what you'd expect from vitamins.”
“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.”
“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.”
