"I used to wake up exhausted every day and suffered from constant brain fog due to Metformin. After a few days with VitalNerve™, I felt more energetic, had clearer focus, and noticed less prickling. I only wish I had found this sooner."

-Andrew L., Manchester

Do you feel completely exhausted every morning, even after 8 hours of sleep? This is almost never "just down to blood sugar". It is caused by your metformin, which blocks B12 receptors in the gut.

In 2022, the UK Medicines and Healthcare products Regulatory Agency (MHRA) updated the patient leaflet to note that 1 in 10 metformin users develops a vitamin B12 deficiency.

VitalNerve™ dissolves under the tongue and bypasses the blocked gut entirely. Many people experience increased energy and mental clarity after the very first tablet.

You are tired because your metformin sabotages the ileum receptors in your gut (Bauman, Diabetes Care, 2000). That is precisely why conventional solutions fail to deliver:

B12 tablets from the chemist → end up in the same blocked gut; 80% is never absorbed.

B12 injections from the GP → provide a short-term effect, but in the UK you only receive them after a formal diagnosis, and GP guidelines do not prescribe routine testing.

VitalNerve™ bypasses the blocked gut completely and enters the bloodstream directly via the fine blood vessels under the tongue.

VitalNerve™ contains a single, clinically dosed, biologically active form of vitamin B12 — no fillers, no synthetic cyanocobalamin.

Methylcobalamin 1000 µg → the bioavailable form that your liver does not need to convert. A 2024 meta-analysis of 13 studies involving 4,275 patients (Abdelwahab, Irish J Med Sci) showed that sublingual methylcobalamin is just as effective as an injection.

Fast-dissolving melt tablet (600 to 900 seconds) → passes directly into the bloodstream via the fine blood vessels beneath the tongue, bypassing the blocked ileum completely.

You will notice the effect as soon as you let VitalNerve™ melt under your tongue:

First tablet (within 1 hour): a clear head; the dull haze behind the eyes lifts.

Day 3: no more afternoon slump; energy lasts through to the evening.

Day 7: sleeping better; hands prickle far less at night.

With regular use: more consistent energy, reduced prickling, and a clearer feeling throughout the day.

I have been taking Metformin for 7 years and genuinely thought I was developing dementia. I placed the first VitalNerve tablet under my tongue and, an hour later, my head felt noticeably clearer. The parcel arrived within 3 days — remarkably fast.

It worked from the very first dose. Initially, I thought: right, just another online pill. But the 60-day guarantee persuaded me. I felt a distinct difference in my energy levels on day one. I am thoroughly, pleasantly surprised.

The prickling in my hands settled down after a few weeks. I felt more energetic from day one. After three weeks, the nighttime prickling in my hands had almost entirely disappeared. I would certainly recommend it to anyone taking Metformin.

Test VitalNerve™ for a full 60 days and experience your energy returning, the brain fog lifting, and the prickling in your hands finally settling down.

If, for any reason, it does not work for you, you will not pay a single penny.

Simply send a short email, and you will receive a prompt, hassle-free refund.

Zero risk. Simply results. Order now and feel the difference from the very first tablet.
