How does CalfCalm work?
Night leg cramps usually aren't about a missing mineral. When you lie still for hours, your calf stays shortened and the nerve that controls it can start firing on its own. CalfCalm combines taurine, which helps support calm nerve and muscle signaling, with vitamin K2 (MK-7) and active B vitamins that support healthy nerves.* You take it at bedtime, so it's there when you need it.
I already take magnesium. Why would this be different?
Magnesium is what almost everyone tries first. But in clinical reviews, magnesium did no better than a placebo for nighttime leg cramps in older adults. CalfCalm takes a different approach: instead of adding another mineral, it supports the nerve-to-muscle signal itself.*
How do I take it?
Two capsules with a glass of water before bed, every night. That's the whole routine.
How quickly will I notice a difference?
CalfCalm isn't a quick fix for one night. Give it 3 to 6 weeks of nightly use. That's why every order comes with our 60-day money-back guarantee.
Who should not take CalfCalm?
Do not take CalfCalm if you take warfarin or another vitamin K antagonist blood thinner. If you're pregnant, nursing or on prescription medication, check with your healthcare provider first. Keep taking any medication your doctor prescribed.
Everything your calves need at night. Nothing they don't.

Night leg cramps don't start in your muscle. They start in your nerve.
Your calf isn't missing magnesium. It's getting signals it never asked for.

When you lie still for hours, your toes point down and your calf stays shortened. The nerve that controls that muscle can start firing on its own, and your calf answers by locking up as hard as it can. That's why more water, more bananas and more magnesium so often let people down: in clinical reviews, magnesium did no better than a placebo for nighttime leg cramps in older adults. CalfCalm supports the signal itself.*
1. Calm the signal
Taurine helps support calm, steady communication between your nerves and muscles.*
2. Support nerves and muscles
Vitamin K2 (MK-7) and active B vitamins support healthy muscle and nerve function through the night.*
No quinine. No magnesium overload. Nothing to drink at 3 a.m.
A short, studied formula
Three ingredients, chosen for what happens in your calves at night.

Vitamin K2 (MK-7)
A form of vitamin K that supports healthy muscle function.*
Vitamin K2 has been studied in older adults with nighttime calf discomfort. Research is ongoing.
Taurine
An amino acid that helps support calm nerve and muscle signaling.*
In a placebo-controlled study, taurine reduced how often muscles seized up in adults with a liver condition.
Active B vitamins
Support healthy nerve function, all the way down to your feet.*
Study results refer to individual ingredients, not to the CalfCalm formula.
Most remedies add a mineral. CalfCalm supports the nerve.
