Magnesium Cream Pregnancy: How They Work and When to Use Them

  • January 22, 2025

Pregnancy is a magical time, but let’s be honest, it can also be a little uncomfortable. Muscle cramps, insomnia, and backaches often sneak their way in, especially as your bump grows. That’s where magnesium cream in pregnancy can be a game-changer.

Used by midwives, doulas, and expecting mums across Australia, magnesium cream offers a gentle, natural way to support sleep, reduce muscle tension, and promote calm during all stages of pregnancy. In this article, we’ll explore how magnesium creams work, when to use them, what to look out for when choosing one, and what to pack for comfort throughout your pregnancy journey.

What Is Magnesium Cream and Why Is It Useful in Pregnancy?

Magnesium is an essential mineral that supports over 300 bodily functions, including muscle function, nerve regulation, and sleep quality. During pregnancy, your body’s demand for magnesium increases to support your growing baby, regulate hormones, and reduce common pregnancy complaints like:

  • Leg cramps and restless legs

  • Difficulty sleeping or staying asleep

  • Anxiety or heightened stress

  • Tight, sore shoulders or back pain

A magnesium cream delivers this mineral topically, meaning it's absorbed through the skin rather than the digestive system. This can be a gentler alternative to supplements, especially for mums who are already taking prenatal vitamins or have sensitive stomachs.

According to Body Bio, magnesium may help relieve muscle cramps and improve overall comfort during pregnancy.

How Magnesium Cream Works

Magnesium creams are typically made using magnesium chloride, known for its high absorption rate. When you massage the cream into your skin, it begins to absorb into the bloodstream, bypassing your digestive tract and delivering targeted relief.

Think of it like a relaxing mineral massage, but with real benefits.

Key Benefits of Using Magnesium Cream During Pregnancy:

  • Relieves muscle aches (especially in the calves, shoulders, and lower back)

  • Reduces night-time leg cramps and tingling

  • Supports deeper, more restful sleep

  • Promotes relaxation by calming the nervous system

  • Soothes the skin when combined with nourishing ingredients like shea butter or almond oil

Unlike oral supplements, magnesium cream doesn’t usually cause side effects like upset stomach or diarrhoea making it a gentle option for sensitive tummies.

When to Use Magnesium Cream in Pregnancy

There’s no one-size-fits-all answer, but many mums find magnesium cream most helpful during:

Bedtime

Apply magnesium cream to your calves, feet, shoulders, or lower back before bed to promote muscle relaxation and deeper sleep.

After Showers

Warm skin absorbs magnesium more effectively. After a warm shower, massage the cream in for extra absorption and a calming ritual.

After Long Days

Been on your feet all day? Use magnesium cream to ease swollen legs, achy hips or back tension—especially in the third trimester.

During Restless Periods

If you’re struggling with restless legs syndrome (RLS), a common pregnancy complaint, magnesium cream can help calm the twitchiness and bring relief.

What to Look For in a Pregnancy-Safe Magnesium Cream

Not all creams are created equal, especially when you're expecting. Here's what to check before you buy:

  1. Pregnancy-safe ingredients: Avoid artificial fragrances, parabens, or harsh chemicals. Look for plant-based, nourishing additions like shea butter, sweet almond oil, and vitamin E.

  2. High-quality magnesium chloride: This is the most easily absorbed form and is gentle enough for daily use.

  3. Non-greasy texture: You want something that melts into the skin, not something sticky that lingers on your sheets.

  4. Locally made & tested: Aussie-made products like the Sleepybelly Magnesium Body Cream are crafted with pregnancy in mind, so you know you're in safe hands.

What to Pack in Your Pregnancy Comfort Kit (Including Magnesium Cream!)

Whether you’re in your second trimester or packing your hospital bag, here’s what to include for those ahh-level comfort moments:

  • Magnesium Body Cream – A bedside staple for sleep support and muscle relief

  • Pregnancy Pillow – Like the Sleepybelly Pillow, designed to reduce hip and back pain

  • Compression socks – To improve circulation on long days or flights

  • Soothing lip balm & hand cream – Hormonal shifts can make skin feel dry

  • Hydration support – A good quality water bottle or coconut water for electrolyte balance

  • Essential oil roller – A natural way to manage nausea or stress (check they’re safe for pregnancy)

  • Breathable loungewear or pyjamas – Like our Three-Piece Maternity Pyjamas for stretch, softness and support.

Can You Use Magnesium Cream While Breastfeeding?

Absolutely, provided it’s a pregnancy and breastfeeding-safe formula (always check the label). In fact, many mums find magnesium cream continues to be helpful post-birth to support:

  • Shoulder and neck tension from breastfeeding

  • Sleep deprivation

  • Anxiety or restlessness

  • General muscle recovery

It’s a beautiful way to wind down during the chaos of new motherhood—without adding another pill to your routine.

Final Thoughts

Pregnancy is full of surprises, but comfort doesn’t have to be elusive. A simple product like magnesium cream can make a real difference, offering natural, soothing support for sore muscles, sleepless nights, and daily tension.

So whether you're 12 weeks in or counting down the final days, having a tube of magnesium cream in your bag (and by your bed) is one of those little things that makes a big impact.

Explore our Sleepybelly Magnesium Body Cream and give your body the gentle support it deserves.

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.
