Free yourself from exhaustion — without injections or prescriptions
Tired of feeling constantly drained, thinking slowly, or dealing with tingling in your hands or feet? It could be a hidden B12 deficiency — something that affects 1 in 10 people and a full 31% of people over 50, including meat eaters with poor absorption.
Regular B12 tablets rarely help. They often contain the wrong form (cyanocobalamin), and the body absorbs only 1–2%.
Nusava™ uses 5,000 mcg methylcobalamin plus four synergistic B vitamins — delivered under the tongue for up to 98% absorption.
Many people notice a difference in just a few days: more energy, clearer thinking, reduced tingling, and a steadier mood.

Why 74 million Europeans suffer from B12 deficiency
The uncomfortable truth: B12 deficiency is widely misdiagnosed.
Many people with levels of 200–300 pmol/L receive no treatment despite clear symptoms. Research links brain fog to around 250, fatigue to 300, and tingling sensations at 350 pmol/L.
Deficiency is common among vegans/vegetarians, people over 50, those taking Metformin or PPIs, and anyone with digestive issues. Across Europe, rates are estimated at 10–31%.
Nusava™ is taken sublingually and raises levels quickly. More than 50,000 Europeans have already noticed a difference.

“I’ve tried countless vitamins before with no results, but this was different. After just the first week, I noticed my energy coming back. I fell asleep faster, woke up more refreshed, and actually had the energy to do things in the evenings again. I finally stopped feeling like a phone constantly stuck at 10% battery.”

“I work in a job that requires lots of structure and sharp focus all day. For months I’d felt mentally slow, like my brain was moving through syrup. After taking Nusava for just a few days, I felt a clear difference — my thoughts flowed, my memory improved, and I could concentrate for hours without losing focus. This has literally saved my workday.”

“I started taking Nusava because of numbness and tingling in my hands. I had no idea it could be linked to 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 emotionally. This is the first supplement that has actually made a difference.”

Place 1.5 ml under your tongue each morning. Hold for about 30 seconds, then swallow. It absorbs directly into the bloodstream through the mucous membrane.
Most people feel increased energy within 7–10 days. Mental clarity often improves after just 3–4 days. Full nerve recovery typically takes 4–6 weeks.
5,000 mcg Methylcobalamin (B12), 3,400 mcg B6, 2,400 mcg B1, 16 mg B3, 400 mcg Folate (B9).All in bioactive forms, with natural raspberry flavor and no sugar.
Extremely safe. B12 is water-soluble — your body uses what it needs and flushes out the rest. No toxic limit. A mild warm sensation from niacin may occur, but no serious effects.
Yes. Most other products use low-dose cyanocobalamin that you swallow — resulting in almost no absorption.
Nusava™ uses 5,000 mcg methylcobalamin taken sublingually, delivering up to 98% absorption. Completely different.
Injections bypass digestion but require doctor visits, needles, and often create uneven levels.
Nusava™ provides the same absorption, but with steady daily dosing and extra support from the full B-complex.
Yes, 100% vegan. Since 40–62% of vegans and vegetarians have B12 deficiency, supplementation is essential.
Yes. Peripheral neuropathy is a classic sign of B12 deficiency. Nusava™ contains exactly the B-vitamin combination (B12, B1, B6) used clinically for nerve repair. Symptoms typically improve within 1–2 weeks.
94% experience improvements — but if you don’t, our 90-day guarantee applies in full.
If you have absorption issues (due to age, medication, digestive problems, or a plant-based diet), long-term use is recommended to maintain optimal levels. Many choose to continue indefinitely.
