The burning at night was unbearable. Waking up at 2am every single night for over a year. Week four I slept through. Haven't looked back.

Couldn't sit through a meal without having to stand up. Couldn't drive more than fifteen minutes. Six weeks in both have changed. My husband noticed before I did."

I used to walk everywhere. Sciatica turned me into someone who watched from the window. Eight weeks in I'm back out. Not perfect but back out."

FAQs

Got questions? We’ve got answers...

Can a cream actually reach deep enough to affect the sciatic nerve?

Most creams can't — and that's exactly the problem. Menthol-based creams like Deep Heat work on cold receptors in the skin, which is why the relief only lasts twenty minutes.

Magnesium chloride and niacinamide are smaller molecules that absorb transdermally — through the skin barrier into the tissue beneath.

The sciatic nerve pathway runs through muscular tissue that is reachable this way. It's a fundamentally different mechanism to surface cooling.

How long before I notice something?

Most customers notice the first small changes within one to two weeks — typically sleep improving slightly or morning stiffness settling faster.

The bigger shifts tend to happen between weeks six and ten with consistent twice-daily use. This is normal — nerve tissue responds gradually, not instantly.

That's why the 180-day guarantee exists. It gives you the full time the mechanism actually needs.

What if it doesn't work for me?

Contact us within 180 days and we'll refund every penny. No forms, no phone calls, no questions asked.

We offer this because we're confident in the formula — but also because we know you've probably spent money on things that didn't work before.

The guarantee removes that risk entirely.

Is it safe to use alongside my current medications?

Calmnerva is a topical cream — it's applied to the skin, not swallowed. This means it doesn't interact with medications the way oral supplements can.

That said, if you're on prescription medication or have an existing health condition, we'd always recommend checking with your pharmacist or GP before use. They'll be able to advise based on your specific situation.

Is this just another magnesium cream?

Most magnesium creams are formulated for general muscle relaxation.

Calmnerva is specifically formulated for sciatic nerve health — combining magnesium chloride with niacinamide, which is a direct precursor to NAD+, the energy molecule nerve cells need to function and repair.

That combination, applied directly to the nerve pathway, is what makes it different from a generic magnesium body cream.

Is there a money-back guarantee?

GPs prescribe from the NHS formulary — medications that have gone through full clinical trial processes.

Natural topical formulations sit outside that scope. It doesn't mean they don't work. It means they're not part of the system your GP operates within.

Many of our customers come to Calmnerva after exhausting what the NHS could offer them.
