What are magnesium cream benefits? Magnesium cream can be a pleasant option for moisturizing skin and massaging a sore area, but the research on magnesium getting through skin is limited and mixed. A 2017 randomized pilot study gave 25 people either cream delivering 56 mg of magnesium per day or a placebo for two weeks; serum and urine magnesium rose more in the cream group, but the statistically significant result appeared only in a subgroup of non-athletes. That is a useful early signal, not a promise of pain relief for a finished cream.

What does the human research actually show?
The 2017 magnesium cream pilot study examined blood and 24-hour urine magnesium after two weeks of daily cream use. It used 56 mg per day. The full cream group had an 8.54% rise in serum magnesium and a 9.1% rise in urine magnesium, but those changes were not statistically significant for the whole group.
A 2015 feasibility study enrolled 40 women with fibromyalgia and asked them to use magnesium chloride spray on each limb twice daily for four weeks. Twenty-four completed it, and questionnaire scores improved. It was a small preliminary study of a spray, not proof that any magnesium cream will help a painful condition.
A 2017 review, Myth or Reality—Transdermal Magnesium?, concluded that claims for magnesium absorption through skin were not scientifically supported by the research available at that time. Taken together, these studies leave a straightforward answer: skin application may change magnesium measures in some settings, but there is not yet strong human research showing that a retail magnesium cream delivers a dependable body-wide magnesium dose or a dependable pain result.
That matters because magnesium itself has important jobs in muscle and nerve function, blood sugar control, and normal heart rhythm, as the NIH magnesium fact sheet explains. Those body functions do not tell you how much magnesium a particular cream delivers through your skin.
Where should you apply magnesium cream?
For a cream sold for topical use, apply it only to intact skin in the area you want to massage, following that product’s label. Keep it away from eyes, mouth, and broken or irritated skin. Do not assume that applying it over a painful spot sends magnesium to the nerve or joint underneath it; the skin-absorption question is still unsettled.
If your pain shoots from the low back into a leg, it can help to understand the pattern. MedlinePlus on sciatica describes pain, weakness, numbness, or tingling that can travel from the low back down a leg. See our guide to magnesium cream safety for a closer look at skin absorption and local reactions.
Can you use magnesium cream every day?
Use the directions on the specific jar. Daily use was part of the two-week cream study, but that does not set a daily dose for every product. A cream with no stated magnesium amount gives you no way to compare its use with the 56 mg-per-day study.
Stop using a topical product if it causes stinging, burning, itching, or a rash. Ask a clinician before trying it if you have kidney disease, are pregnant or breastfeeding, take medicines regularly, or have a heart-rhythm concern. The kidneys help control magnesium balance, and no cream should be used as a substitute for a medication plan.
What should you know about Magnesium Niacinamide Relief?
Magnesium Niacinamide Relief is a topical cream from Peak Health Research. The seller’s page, checked October 7, 2026, also uses the name MagnesiumFreeze. The seller says to apply the cream to the painful area and names magnesium niacinamide, arnica, and boswellia as its three components.
The seller materials do not show a full ingredient list or amounts for those components. They also do not show a Drug Facts label. That makes it different from an over-the-counter pain reliever, whose active ingredient and labeled uses appear in Drug Facts. Research on an ingredient is not a result for this finished cream.
For context, the NCCIH boswellia overview says topical boswellia has been studied, but there is not enough evidence to show it is effective for a health condition. Arnica and niacinamide amounts are also not listed here, so you cannot match this jar to an ingredient dose used in a study.

What are the real signs of low magnesium?
There is no reliable seven-sign checklist, and cravings do not diagnose low magnesium. Magnesium status is not simple to judge from symptoms or one number because most magnesium is inside cells or bone. The NIH notes that a clinical assessment and laboratory testing may both be needed.
Magnesium is present in many foods. If you are looking for a drink rather than a cream, the information here does not identify one drink as high in magnesium. A clinician or dietitian can help you compare your usual food and drink intake with the adult recommended intake range of 310 to 420 mg per day described by the NIH.
Does magnesium help AFib, and do cardiologists recommend it?
Magnesium plays a role in normal heart rhythm. That does not mean a topical cream is an answer for atrial fibrillation, often called AFib. Magnesium given in medical care can be very different from magnesium in food, pills, or a cream. If you have palpitations, a known rhythm issue, chest symptoms, fainting, or a question about magnesium and heart medicines, bring the product label to your cardiology visit before using it.
When is pain more urgent than a cream?
Get prompt medical care for sciatica or nerve pain with new weakness, numbness in the groin or saddle area, loss of bladder or bowel control, fever, or pain after an injury. The NIAMS back pain guide also flags weakness, trouble urinating, fever, and pain after a fall or injury as reasons to seek medical attention.
Before you order or bring this up at a visit

- Track where the pain starts, where it travels, numbness or weakness, and what movements change it.
- Ask the seller for the full ingredient panel, the amount of each named component, jar size, and return steps before ordering.
- Say: “I am considering a topical magnesium product. Does it fit with my kidney health, heart history, and medicines?”
- If you are considering this specific product, read our practical guide on Magnesium Niacinamide Relief timing.
