Study-Backed to Support Diabetic Nerve Health

This formula uses clinically studied B-vitamins that target the specific nutrient drains diabetes creates—supporting nerve structure, addressing nutrient depletion, and promoting long-term nerve health.

🔴 Methylcobalamin (B12) 5,000 mcg — Active form essential for myelin sheath repair and nerve regeneration. Diabetes + metformin both deplete this. Studies show 64% of neuropathy patients on metformin are deficient.

🟠 Thiamine (B1) 2,400 mcg — Critical for redirecting sugar away from nerve-damaging pathways. Diabetics flush B1 at 16-24x normal rate. When B1 drops 75%, sugar strips nerve insulation—that's the burning at 3am.

🟡 Pyridoxine HCl (B6) 3,400 mcg — Helps regulate nerve signal transmission and neurotransmitter balance. Kept at safe therapeutic levels—most B-complexes hide dangerous amounts that worsen neuropathy long-term.

🔵 Niacin (B3) 16,000 mcg — Supports healthy circulation and blood flow to nerve endings. Essential for delivering nutrients and oxygen to damaged nerves.

💛 Folate (B9) 400 mcg — Works with B12 for methylation and DNA repair. B12 works synergistically with folate to support myelin—they're cofactors, not solo workers.

🖤 Sublingual Liquid Delivery — Bypasses the gut entirely. Critical for metformin users whose B12 absorption is blocked. Goes directly into bloodstream through tissue under tongue.


Each serving delivers targeted support to address nerve nutrient depletion and support nerve structure—targeting nutritional factors, not just symptoms.

How Does It Help?

This formula supports your nerves by addressing what diabetes and metformin deplete—in forms your body can actually use, delivered in a way that works even with gut absorption issues.

Calms burning, tingling, and numbness naturally by restoring the B1 "detour switch" that redirects sugar away from nerves

Supports nerve insulation with the full repair team — B12 + folate + B6 working together, not B12 alone

Bypasses metformin's B12 blockage with sublingual delivery that goes straight to bloodstream

Absorbs fast with liquid delivery — no pills sitting in your gut hoping to get absorbed

Works nightly to support nerve function, not just cover symptoms — targets the 3am nerve misfiring window when your brain does neuroplastic repair

Whether you're trying to avoid gabapentin or already on it and looking for additional support, this addresses the nutritional deficiency that's driving the damage—not just numbing the pain.

When will I see results?

24 HOURS

Many users report feeling more energized and mentally clearer after the first dose as B-vitamins begin supporting cellular energy production.

WEEKS 1-2

You're loading depleted nutrients and reactivating the B1 detour pathway. Most people don't feel dramatic changes in nerve symptoms yet—nerves repair slowly. This is the foundation phase.

WEEKS 3-4

This is when first shifts typically appear. Less intense burning. Sleeping longer stretches before waking. Able to sit through meals without needing to pace. Small but real changes.

WEEKS 5-8

Myelin support phase. Many report waking up and realizing their feet didn't wake them at 3am.Better balance. More confident driving. The fan stays off more nights.

WEEKS 9-12

System consolidation. Less damage + ongoing repair + better sleep = calmer baseline. First "easy" nights in years. This is when people call it "worth it."

2+ MONTHS

Sustained use maintains gains and protects long-term nerve health. Many transition to maintenance dose (1mL vs 2mL) after week 12.

Not feeling anything at week 4? That's normal for 20% of people. Nerves regenerate at different rates. Keep going through week 8. The 180-day guarantee gives you time to see your personal timeline.

The Depletion Behind Diabetic Nerve Pain

Three AM. Feet on fire. You're up again. Fan pointed at the bed. Every cold spot on the kitchen floor memorized.

Blood sugar is managed. A1C is better. But the burning stays.


Here's what often goes untested:

Diabetes dumps B1 at 24x normal rate. B1 keeps sugar from shredding nerve insulation. When it drops 75%, sugar strips your myelin coating. That's the burning.

Metformin blocks B12 in your gut. B12 supports myelin structure. So more damage, less support.

Standard panels rarely test both together.

This is common and often overlooked ...

Five Nutrients. One Liquid. Two Milliliters At Night

Your body is depleting:

  • B1 (redirects sugar away from nerves)
  • B12 (repairs nerve insulation)
  • B3 (restores circulation to damaged nerves)
  • B6 (balances nerve signals)
  • B9 (B12's partner - repair doesn't work without it)

This formula replaces all five. In the right forms. At the right doses. In a sublingual liquid that goes straight into your bloodstream—bypasses the metformin blockage entirely.

Two milliliters under your tongue before bed. That's it.

Metformin Blocks Your Gut. Sublingual Bypasses It.

Metformin blocks B12 absorption in your stomach. Oral capsules just pass through and end up in the toilet.

Sublingual doesn't touch your gut. Hold it under your tongue for 30 seconds. Absorbs directly into your bloodstream. Metformin can't block what never goes through digestion.

"I tried sublingual B12 before. Didn't work."

Because B12 alone can't rebuild nerves. You need B12 + B1 + B3 + B6 + B9 working together.

This is the whole crew.

    Methylcobalamin Works Better:
    In nerve regeneration studies, methylcobalamin outperforms cyanocobalamin significantly.
    Neuroscience Research

    B6 Can Hurt You:
    Daily doses over 50mg are linked to worsening sensory neuropathy long-term.
    Therapeutic Goods Administration

    We didn't make this up. We're just the first people to build a formula around what the research actually says instead of what's cheapest to manufacture.

    Excellent 4.7/5

    "Finally something that actually works"

    "I've been diabetic for 9 years and tried every B12 supplement at CVS. Nothing helped. I'm on metformin so when I read about the sublingual delivery bypassing gut absorption, it made sense. Week 5 the burning started easing up. Week 8 I slept through the night without waking up to pace. Shipping was fast and customer service answered my questions before I ordered."

    "Wish I'd found this sooner"

    “Gabapentin made me too foggy to function. I was desperate for an alternative. This took longer than I wanted (about 6 weeks) but my balance improved enough that I feel safe driving again. My endocrinologist was surprised at my progress. The liquid tastes fine and it's easy to take before bed. Worth every penny.”

    Linda K. | 62 | Manchester, UK 🇬🇧

    Verified customer

    "14 years of suffering, finally relief"

    “I've had diabetic neuropathy since 2011. Tried everything - prescriptions, topical creams, compression socks, every supplement on Amazon. Was skeptical ordering this but the guarantee made me try it. Week 10 I realized I'd slept through three full nights that week. First time in over a decade. Still take it daily and the results have held.”

    "The metformin connection is real"

    "Been on metformin for 8 years. Tried oral B12 for two years with zero results. Reading about how metformin blocks absorption made sense. The sublingual delivery bypasses that problem. Week 5 the burning intensity dropped enough that I could sit through family dinners without needing to stand and walk. Ordering my third bottle now."

    Sarah M. | 51 | Auckland, New Zealand 🇳🇿

    Verified customer

    "Took longer than expected but worked"

    "I'm giving 4 stars because it took a full 8 weeks before I noticed real changes. The product page said some people take longer so I kept going. Around week 9 my balance improved enough that I stopped being scared to walk my dog. Wish it worked faster but I'm glad I didn't quit early. The 180-day guarantee helped me stick with it."

    Robert D. | 67 | Phoenix, Arizona 🇺🇸

    Verified customer

    "Small changes that add up"

    “Week 4 I could wear socks again without crying. Week 6 I put on regular shoes. Week 9 I walked around the mall with my daughter. None of these sound huge but when you've had burning feet for 12 years, being able to wear shoes is everything. The liquid is easy to take and raspberry flavor is actually pleasant. Highly recommend.”

    "Balance improved, confidence returned"

    “My balance got so bad I stopped driving for 6 months. Too scared of causing an accident. Week 9 on this protocol my balance steadied enough that I got back behind the wheel. That feeling of independence returning is priceless. The product works if you give it the full 12 weeks like they say. Don't quit at week 3 like I almost did.”
