The Benefits of Magnesium Balm Relieving Muscle Cramps in Pregnancy

  • February 04, 2025

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 stretched skin

A 2017 review highlights transdermal magnesium as a promising alternative for improving sleep and reducing muscular tension during pregnancy, particularly for those sensitive to oral supplements.

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:

  1. Pregnancy-safe formulations – No artificial fragrances, parabens, or harmful preservatives

  2. Natural, nourishing ingredients – Shea butter, almond oil, or aloe vera for added skin benefits

  3. Transparent sourcing – Look for brands that share where their magnesium is derived

  4. 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.

How to Put On Pregnancy Compression Socks Without Straining Your Belly

How to Put On Pregnancy Compression Socks Without Straining Your Belly

The Physical struggle of pulling on tight compression socks over a growing bump can cause you to strain your lower back or compress your abdomen. By transitioning to the "Inside-Out Method" and adjusting your physical posture, you can slide your garments on seamlessly without putting any pressure on your belly.

Treating compression fabric like a standard sock by scrunching it into a ring creates immense structural resistance. Instead, convert the garment into an accessible foot pocket: slide your hand inside to pinch the heel, peel the long leg sleeve backward so it is completely inside-out down to the ankle, slide your foot into the waiting pocket, and smoothly unroll the fabric up your calf. To keep your abdominal area entirely clear while doing this, use the "Cross-Ankle Lounge" posture on a couch or place your foot on a low step stool so your knees can flare naturally to the sides.

Should You Wear Compression Socks to Bed While Pregnant?

Should You Wear Compression Socks to Bed While Pregnant?

For most expectant mothers, the general rule is to avoid wearing tight, firm compression socks to sleep overnight. Graduated compression garments are specifically engineered to assist your veins in working against gravity while you are upright—standing, sitting, or walking. When you lie flat, gravity stops pulling blood and extra fluids down into your lower limbs, allowing your circulation to naturally even out. Wearing high-pressure stockings horizontally is not only unnecessary, but it also carries a risk of constriction; if the fabric bunches or rolls as you toss and turn, it can create a tight band around your calf that actively restricts blood flow.

The ideal routine is to wear your maternity compression socks for about 30 minutes during your evening wind-down, then slide them off right before you turn out the light. This short pre-bed window provides a final circulation boost to move the day's residual fluid and ease that restless, twitchy end-of-day feeling.

An overnight exception exists only if you are dealing with severe Restless Legs Syndrome (RLS) or intense throbbing that keeps you awake. In those cases, wearing a gentle, low-pressure (15-20 mmHg), breathable garment made from a soft bamboo blend is acceptable, provided it does not dig into your skin. Otherwise, you can support your nighttime circulation bare-legged by utilizing a modular pregnancy pillow to maintain a strict side-sleeping position, which keeps your heavy uterus from compressing the inferior vena cava (the main pelvic vein returning blood to your heart).

Why Pregnancy Swelling Feels Worse at Night, and What Can Help

Why Pregnancy Swelling Feels Worse at Night, and What Can Help

Evening swelling, or gestational oedema, is a common pregnancy symptom caused by increased blood and fluid volume. This puffiness peaks at bedtime due to a combination of daytime gravity pulling fluids downward and your growing uterus compressing the inferior vena cava, which restricts lower-body circulation. When you finally lie flat, your body begins reabsorbing this pooled fluid to be filtered through your kidneys, resulting in a tight, throbbing sensation in your lower limbs just as you try to drift off.

To prevent this evening spike, implement a proactive routine earlier in the day. Front-load your hydration by drinking the majority of your water before 4 pm to help your kidneys flush excess fluid without keeping you awake with a full bladder. When relaxing, elevate your feet above heart level using pillows to let gravity assist your veins, and wear graduated maternity compression socks during the day to provide steady mechanical support that prevents fluid from pooling in the first place. Conclude your evening by massaging a non-greasy magnesium cream into your calves to relieve skin tightness, then settle into a supportive side-sleeping position with a modular pregnancy pillow to keep your pelvic veins completely clear of uterine pressure overnight.
