If you’ve ever been jolted awake at 3 am by a sharp leg cramp while pregnant—you’re not alone. Muscle cramps, restless legs, and body aches are among the most common (and frustrating) side effects of pregnancy, especially as your body adapts to its growing role. The good news? A gentle, natural remedy is gaining well-deserved attention: magnesium balm in pregnancy.
In this guide, we’ll explore what magnesium is, how it works, why it’s pregnancy-safe, and how incorporating a simple magnesium balm into your routine can bring sweet relief—day and night.
What Causes Muscle Cramps During Pregnancy?
Muscle cramps in pregnancy, particularly in the legs and calves, are often caused by a combination of:
-
Increased pressure on nerves and blood vessels from your growing uterus
-
Hormonal changes that affect how your body handles minerals like calcium and magnesium
-
Poor circulation or fatigue—especially in the later trimesters
-
Dehydration or nutrient imbalances, which are more common than you might think
Cramps often worsen at night, making sleep even more elusive for expectant mums.
What Is Magnesium Balm?
Magnesium balm is a topical cream enriched with magnesium chloride, a form of magnesium that can be absorbed through the skin. Unlike oral supplements, which can sometimes upset sensitive tummies during pregnancy, magnesium balm is gentle, targeted, and doesn’t require digestion.
Our Sleepybelly Magnesium Body Cream is specially formulated with mums in mind. It blends naturally derived ingredients like:
-
Magnesium chloride – to help relax muscles and calm the nervous system
-
Shea butter – to nourish dry or stretched skin
-
Sweet almond oil – to hydrate and promote elasticity
-
Lavender – for a calming, sleep-supportive scent
Why Use Magnesium Balm in Pregnancy?
Magnesium plays a vital role in over 300 biochemical reactions in the body—including muscle relaxation, nerve function, and sleep regulation. During pregnancy, your body demands more magnesium than usual, but many women struggle to get enough from diet alone.
Benefits of Using Magnesium Balm in Pregnancy:
-
Relieves leg and foot cramps
-
Soothes back and hip tension
-
Supports more restful sleep
-
Calms the nervous system, helping reduce anxiety
-
Hydrates itchy or stretching skin

How to Use Magnesium Balm Safely During Pregnancy
Using magnesium balm is easy—and safe when used correctly. Here’s what to keep in mind:
-
Apply a small amount to affected areas such as calves, feet, lower back, or shoulders
-
Use before bed to wind down or after a long day on your feet
-
Massage gently into the skin—don’t apply to broken or irritated skin
-
Start with a patch test if you have sensitive skin
-
Store in a cool, dry place to preserve texture and scent
Tip: Pair with gentle stretching or light prenatal yoga to boost results.
What to Look Out For When Choosing a Magnesium Balm
Not all balms are created equal. When shopping, keep an eye out for:
-
Pregnancy-safe formulations – No artificial fragrances, parabens, or harmful preservatives
-
Natural, nourishing ingredients – Shea butter, almond oil, or aloe vera for added skin benefits
-
Transparent sourcing – Look for brands that share where their magnesium is derived
-
Calming scent (or no scent) – Avoid overpowering perfumes, especially if you're sensitive to smells during pregnancy
Our Sleepybelly Magnesium Balm ticks every box—it’s gentle, clean, effective, and designed specifically for pregnancy and postpartum use.
What to Pack for Magnesium-Powered Comfort
If you’re prepping your hospital bag or just building a nightly self-care routine, here’s what to include for full-body relief:
-
Magnesium Balm – Your bedtime go-to for cramps and calm
-
Stretchy, soft sleepwear – Like our Three-Piece Maternity Pyjamas
-
Water bottle – Staying hydrated helps reduce cramping too
-
Essential oil roller or pillow mist – For extra sensory relaxation
-
Journal or affirmation cards – To unwind emotionally before sleep
When to Speak to a Healthcare Professional
While magnesium balm is safe for most women during pregnancy, always check in with your GP, midwife, or obstetrician if:
-
You’re considering combining topical and oral magnesium
-
You have a kidney condition or magnesium-related health concerns
-
Cramps are persistent, severe, or worsening
You can also check guidelines from organisations like Jean Hailes for Women’s Health for more support around pregnancy-safe supplements and remedies.
Final Thoughts
When you're pregnant, every day brings something new—from fluttery kicks to not-so-glamorous leg cramps. Having magnesium balm in pregnancy as part of your routine can make a world of difference. It’s a small, soothing ritual that speaks volumes: I see you, I’ve got you, let’s rest.
Whether you're gifting it to yourself or another mum-to-be, think of magnesium balm not just as a cream—but as a soft exhale in the middle of an intense, beautiful journey.
