Break free from exhaustion – no injections or prescriptions needed
Are you feeling constantly drained, a bit sluggish mentally, or perhaps experiencing tingling in your hands or feet? It could well be a hidden B12 deficiency – something that affects around 1 in 10 Europeans and a rather significant 31% of those over 50, even if you eat meat but have reduced absorption.
Regular B12 tablets often don't quite hit the mark. They frequently contain the wrong form (cyanocobalamin), and your body only tends to absorb a tiny 1–2% of it.
Nusava™, on the other hand, uses 5,000 µg of methylcobalamin along with four synergistic B vitamins – delivered under the tongue for an absorption rate of up to 98%.
Many people find they notice a real difference within just a few days: more energy, clearer thinking, less tingling, and a more stable mood.

Why 74 Million Europeans Are Living with a B12 Deficiency
The rather uncomfortable truth: B12 deficiency is often underestimated.
Many people with B12 levels around 200–300 pmol/L don't receive support, despite experiencing clear symptoms.
Research has linked brain fog to levels around 250, tiredness to 300, and tingling sensations to about 350 pmol/L.
Deficiency is quite common among vegans and vegetarians, those over 50, people using Metformin or antacids, and those with gut issues. In Europe, the prevalence is estimated at 10–31%.
Nusava™ is taken sublingually and tends to raise B12 levels rather quickly. Over 50,000 Europeans have already noticed a difference.

“I’ve tried countless vitamins before with no real luck, but this felt genuinely different.
After just a week, I started to feel my energy coming back.
I was falling asleep more easily, waking up feeling refreshed, and even had the get-up-and-go to do things in the evenings again.
Finally, I don't feel like a phone constantly stuck on 10% battery.”

“My work is very structured, and I need to stay sharp all day.
For the past few months, my mind felt sluggish, as if my thoughts were wading through treacle.
After a few days with Nusava, I noticed a difference straight away – my thoughts were flowing smoothly again, my memory felt better, and I could concentrate for hours without drifting off.
It’s genuinely made a huge difference to my workday.”

“I started taking Nusava because of tingling and numbness in my hands.
I hadn't realised this could be linked to a B12 deficiency.
About two weeks later, I noticed a clear improvement.
The feeling has almost completely returned, and I feel much more balanced, both physically and mentally.”
“This is the first time a supplement has really made a difference.”

Simply place 1.5ml under your tongue each morning. Hold it there for about 30 seconds, then swallow. It's absorbed directly into your bloodstream through the lining of your mouth.
Most folks tend to feel a boost in energy within 7–10 days. Mental clarity often improves even sooner, sometimes after just 3–4 days. For a more complete nervous system recovery, it usually takes around 4–6 weeks.
You'll find 5,000 µg of methylcobalamin (B12), 3,400 µg of B6, 2,400 µg of B1, 16 mg of B3, and 400 µg of folic acid (B9). All in their bioactive forms, with a natural raspberry flavour and no added sugar.
It's remarkably safe. B12 is water-soluble, so your body uses what it needs and simply flushes out the rest. There's no known toxic limit. You might experience a slight warming sensation from the niacin, but nothing serious to worry about.
Yes, quite possibly. Many other products contain lower doses of cyanocobalamin that you swallow, meaning very little is actually absorbed. Nusava™ uses methylcobalamin (5,000 µg) which is taken sublingually, allowing for up to 98% absorption. It's a rather different approach altogether.
Injections bypass digestion, but they do involve doctor visits, needles, and can often lead to fluctuating levels.
Nusava™ aims for a similar absorption, but with a steady daily dose and the added benefit of a full B-complex to support you.
Yes, it's completely vegan-friendly. Given that 40–62% of vegans and vegetarians may experience a B12 deficiency, supplementing can be quite important.
Yes, it might. Peripheral neuropathy is a common symptom of B12 deficiency. Nusava™ contains a blend of B vitamins (B12, B1, B6) that are often used in clinical settings to support nerve recovery. Many people find their symptoms ease within 1–2 weeks.
Around 94% of people experience an improvement. But if you don't, our 90-day, no-fuss guarantee has you covered.
If you have absorption challenges (perhaps due to age, medication, stomach issues, or a plant-based diet), ongoing use is often recommended to help maintain optimal levels. Many people choose to continue taking it indefinitely.
If you have absorption issues (perhaps due to age, medication, stomach complaints, or a plant-based diet), long-term intake is often recommended to help maintain good B12 levels. Many users choose to continue as long as it feels right for them. Don't let a B12 deficiency hold you back any longer. Why not give Nusava™ a try now – and you could be feeling more like yourself before long.
