Nine years my GP told me the tiredness was just my diabetes. Nine years. Started this on a Tuesday. By the Saturday I'd slept a full night for the first time in I can't remember how long. My granddaughter asked me last month why I "seemed like me again". Cried in the kitchen. Ordered another two bottles.

Yes, I recommend this product.

Clear Brain Fog And Pins-And-Needles Without Daily Injections

Are you swallowing B12 pills that never seem to work? That's not your fault, metformin blocks the exact gut door regular tablets rely on.

Met12™ dissolves under your tongue instead, delivering 2,000mcg of active methylcobalamin straight into your bloodstream. Many people notice the afternoon slump simply doesn't arrive from day one.

You Are One Step Closer To Ending Metformin-related Fatigue, For Good.

British-made, Doctor-Referred Formula Built To Bypass The Metformin Block

How does one small cherry tablet do what a bottle of Boots B12 couldn't?

1

Methylcobalamin 2,000mcg — the pre-activated form, no liver conversion needed

2

Sublingual cherry tablet — absorbed under the tongue, bypasses the blocked ileum

3

UK-made, GMP-certified — third-party batch tested, no fillers, no cyanide traces

4

Pharmaceutical-grade Swiss B12 — the exact form used in the Sharabi 2003 trial

Together, they finally get you waking up with energy — solving metformin-driven fatigue for good.

Finally Wake Up Feeling Like You Again, And Feel The Fog Lift

Here is what you will experience when you try Met12™:

1

Hour 1: The cherry tablet dissolves under your tongue and methylcobalamin absorbs straight into your bloodstream — skipping the ileum metformin has jammed. Many notice a subtle mental clarity by lunchtime.

2

Day 3: Your nerves start receiving fuel they've been starved of for years. Pins and needles begin to fade. Afternoon energy holds steady where it used to collapse at 3pm.

3

Day 10: Word-finding sharpens, sleep deepens, and the wool socks start feeling excessive. Most people report feeling in their feet returning by this point.

4

Continued Use: Nerves rebuild their myelin sheath, energy normalises, and you simply stop thinking about the tiredness. You get you back — permanently, for as long as you keep the door open.

Been on metformin fourteen years, numbness in the feet was doing my head in. Two weeks on the tablets and I can feel the pedals in my car properly again. Wife noticed I was going up the stairs two at a time, hadn't done that in years.

Customer service was really good, had a question about taking it alongside my amlodipine and they got back same day. Arrived in five days, well packaged. Twelve days in and the tingling's gone from my hands. Ordering another two.

Wasn't sure it'd do much honestly, tried every B12 tablet in Boots over the years. Ten days in and the fog's just gone. Sleeping properly, walking the dog the full route again. Really happy with this.

Answers to All Your Questions:

How do I use it?

Place one cherry tablet under your tongue each morning and let it dissolve for 60 seconds.

How fast does it work?

Most people feel a lift in energy within 24 hours and reduced tingling within 10 days.

What's in it?

2,000mcg pharmaceutical-grade methylcobalamin in a natural cherry sublingual base — nothing else.

Why sublingual?

Because metformin blocks gut absorption, so a tablet under the tongue is the only reliable route.

Is it safe?

Yes — B12 has no upper intake limit and Met12™ is UK-made in a GMP-certified facility.

What if it doesn't work?

You get every penny back within 90 days, no forms, no questions.

Can I take it long-term?

Yes — daily use is recommended for as long as you're on metformin.

Do I need a prescription?

No, Met12™ is a food supplement and available without a prescription.

Is it vegan-friendly?

Yes, the methylcobalamin is plant-fermented and the tablet base is fully vegan.

Can I take this with metformin and other meds?

Yes — B12 has no known interactions with metformin, blood pressure meds, or statins.

How long does shipping take?

Orders typically arrive within 5–7 days and you'll get a tracking number by email once shipped.

 What if my B12 test came back "normal"?

"Normal range" was set decades ago and metformin drops B12 by ~20% yearly, so many patients are functionally deficient inside "normal."
