MagnesiumFreeze is a topical cream, and its maker, Peak Health Research, has no side-effects section for it. The ingredient list is your best guide: it includes menthol, camphor, peppermint oil, tea tree oil and arnica, all of which sit on your skin. If you have numb feet, take medicines, are pregnant or nursing, or have a medical condition, ask a pharmacist or doctor before you use it.

What side effects can MagnesiumFreeze cause?
The seller's product page describes benefits and does not describe side effects, so there is no seller-published list to quote. What you can do is read the ingredients and know what to watch for on your own skin.
For comparison, the NHS says another nerve-pain cream, capsaicin, can cause skin irritation and a burning or itching sensation where it is applied, and advises against using it on broken or inflamed skin. That is the NHS's advice about capsaicin, not about MagnesiumFreeze. Ask the seller or a pharmacist whether the same skin precautions apply to this cream.
If you use it and notice a rash, itching or burning, tell a pharmacist or clinician. Our guide to noting down a side-effect timeline shows what to write down so they can help you faster.
What is in MagnesiumFreeze?
The seller's product page lists these ingredients and the role it gives each. No amounts are printed, and vitamin B6 appears only in the FAQ list.
| Ingredient | Role the seller gives it |
|---|---|
| Magnesium chloride | Magnesium said to absorb through the skin for cellular energy and repair |
| Niacinamide (vitamin B3) | Healthy inflammatory response and tissue recovery |
| Vitamin B6 | Listed in the FAQ; no role given |
| Arnica montana | Traditional botanical for soreness, bruising and swelling |
| Boswellia (frankincense) | Joint comfort |
| Menthol and camphor | Cooling relief on contact |
| Peppermint oil and tea tree oil | Cooling and soothing |
| Coolact and Hotact | Cooling followed by gentle warming |
| Vitamin E | Antioxidant support for skin |
| Shea butter and aloe vera | Moisturizing base |
Because the page gives no amounts, ask support ([email protected] or (888) 811-1186) for the full label with the quantity of each ingredient. Do this before you order if you have allergies to plants, oils or fragrance-type ingredients.
Who should check with a doctor or pharmacist before using it?
The seller's own footer on its OsteoShield page says that if you are pregnant, nursing, taking medication or have a medical condition, you should consult your physician before using its products. Its terms also tell you to consult a healthcare professional before starting any supplement program or if you have or suspect a health problem. Beyond that, independent medical sources point to these groups:
| If this is you | Why to ask first |
|---|---|
| Numb or low-feeling feet, or diabetes | Cleveland Clinic lists burns from not feeling pain as a complication of neuropathy, and a clinic guide from CLS Health warns that heat on numb areas can burn without warning. The seller describes a warming effect, so ask whether it suits your feet. |
| Broken, inflamed or very sensitive skin | The NHS gives this precaution for capsaicin cream; ask whether it applies here. |
| Taking prescription medicines | The seller itself recommends checking with your doctor or pharmacist. |
| Pregnant or nursing | The seller advises consulting your physician. |
| Kidney disease, or taking oral supplements too | CLS Health says not to start high-dose supplements without medical guidance, especially if you take medications or have kidney disease. |
| Already taking vitamin B6 | The Foundation for Peripheral Neuropathy says both too little and too much B6 can cause peripheral neuropathy. That note is about B6 in general, and the product page gives no B6 amount, so ask support. |

Can I use it with my medicines?
The seller's FAQ says MagnesiumFreeze is topical and does not interfere with oral medications, and then adds that it always recommends consulting your doctor or pharmacist first. Take the second half seriously. Bring the jar or its ingredient list to your pharmacist, and mention any nerve-pain medicine you take. The NHS notes that common nerve-pain medicines such as amitriptyline, duloxetine, pregabalin and gabapentin can cause tiredness and dizziness, so tell your pharmacist if you are on any of them.
I cannot tell you to start, stop or change a medicine. That decision belongs with your prescriber.
Where do you put it, and how often? What about feet at night and sleep?
The seller's directions are to apply a quarter-sized amount to the sore area and rub in circular motions for 30 to 60 seconds until absorbed. The seller says to use it 2 to 3 times daily: morning, midday and before bed. It lists knees, lower back, feet, hands, neck, shoulders and hips as places to use it, and says one jar lasts 30 days on one or two areas.
The page does not present MagnesiumFreeze as a sleep product. Its timeline says nighttime discomfort decreases by weeks 3 to 4, which is the seller's claim. Foot nerve pain often feels worse at night, according to Austin Foot and Ankle Specialists, so a bedtime application is aimed at that pain rather than at sleep itself. If your feet have little feeling, ask a clinician how much and how often is right for you before following the seller's schedule.
Does it really work on knees and nerve pain?
The seller says you will feel relief in minutes and that benefits build with daily use over a month or two. The accounts on its pages, such as burning feet dropping from a 9 out of 10 to a 2 or 3, and knee grinding easing, are the seller's own testimonials. The page also cites a 13,000-person study on magnesium and discomfort without naming it. Your results may differ, and the seller's terms say it does not guarantee you will reach your health goals.
Menthol and camphor are described by the seller as cooling the skin and quieting surface pain signals. A cooling sensation can feel good, but it does not tell you why your knees or nerves hurt. That is the real question to put to a clinician if the pain keeps coming back.
Is MagnesiumFreeze legit, and where is it made?
It is a real product sold by Peak Health Research, with a working support line and email, a return policy, and a 180-day money-back guarantee. The seller's official site is peakhealthresearch.com. Its own pages disagree on some details, so confirm these before you buy:
- Single-jar shipping: the product page says $9.99; the shipping policy says $6.95 for its one-bottle package.
- Where it ships from: the product page says Tennessee, FL; the homepage says products are manufactured and bottled in Tampa, FL.
- Quality checks: the seller says products are made in the USA in GMP-certified facilities and that each batch gets quality-control checks for purity and consistency. For third-party testing, it tells you to ask support about specific concerns.
Dietary supplements are not required to be approved by the FDA before they are sold, as the seller's FAQ itself says, and its site states that its statements have not been evaluated by the FDA.
What if my side effects mean I want a refund?
The seller promises a full refund within 180 days. Contact support by email ([email protected]) or phone ((888) 811-1186) with your order number. The return policy says the item must be in the same condition you received it and in its original packaging, and that you need a receipt or proof of purchase. The FAQ says refunds take 5 to 10 business days to appear. A jar you have already used may not meet the condition rule, so ask support in writing whether a used jar qualifies. If you were put on a subscription, the seller says you can cancel through your account portal or by email.
What about magnesium pills or "calm" magnesium?
This page is about the cream. Oral magnesium products and drinks are different products with different ingredients and amounts. If you are considering one, CLS Health's advice applies: do not start high-dose supplements without medical guidance, especially if you take medications or have kidney disease. Take the product's label to a pharmacist who can check it against your medicines.
What works for nerve pain in the feet?
Is there anything that works immediately?
Not reliably. The NHS says nerve (neuropathic) pain does not usually get better with common painkillers such as paracetamol and ibuprofen. Doctors instead use medicines such as amitriptyline, duloxetine, pregabalin and gabapentin, started at a low dose and raised gradually until you notice an effect. Side effects such as tiredness and dizziness often ease after a week or two.
The NHS also describes capsaicin cream or patches for nerve pain, with the skin warnings above. The Foundation for Peripheral Neuropathy lists numbing options such as the prescription cream EMLA and lidocaine patches. Neither organization lists Vicks VapoRub as a neuropathy treatment, so ask a pharmacist before putting a menthol or camphor rub on numb feet.
What triggers foot nerve pain?
Cleveland Clinic says diabetes is the most common cause of peripheral neuropathy, and it often affects the feet first. Other causes it lists include:
- Vitamin deficiencies (B1, B6, B9, B12, E and copper)
- Long-term heavy alcohol use
- Certain medicines, including chemotherapy and some antibiotics
- Toxin exposure
- Autoimmune conditions
- Infections such as shingles
- Kidney or liver disease
- Pinched nerves and injuries
- Inherited conditions
Austin Foot and Ankle Specialists adds smoking and poorly fitted shoes. In some people no cause is found.
Can foot nerve damage be reversed or heal on its own?
It depends on the cause. Cleveland Clinic says it is possible to stop or may help address certain types if they are diagnosed and treated quickly, and that the more severe and longer-lasting the damage, the less likely it is to be reversible. The NHS says controlling diabetes may improve neuropathy or at least stop it getting worse, and that neuropathy caused by a medicine may improve if the medicine is stopped; that is a decision for your prescriber. Austin Foot and Ankle Specialists says nerve pain will not go away on its own and that ignoring it risks long-term damage.
What vitamin repairs nerve damage?
No vitamin repairs nerve damage in general. If your nerve problem comes from a deficiency, treating that deficiency is the fix. The NHS says vitamin B12 deficiency can be treated with B12 injections or tablets. It says the evidence for benfotiamine (a form of vitamin B1) and alpha-lipoic acid supplements is not always clear, and to speak to a doctor before trying them. The Foundation for Peripheral Neuropathy warns that several nerve supplements may have adverse effects and should not be started without a physician's supervision.
When should you get care promptly?
CLS Health says to seek medical attention promptly for rapidly worsening weakness, new or worsening balance problems or falls, open sores or ulcers on the feet, signs of infection (redness, warmth, swelling, drainage), or new numbness that is spreading or worsening. Sudden numbness with facial drooping, confusion, trouble speaking or one-sided weakness needs emergency care. Cleveland Clinic advises seeing a provider at the first signs of peripheral neuropathy, because early treatment gives the best chance of stopping or reversing some types.
Before you order
- Ask support for the full ingredient list with the amount of each ingredient, including vitamin B6.
- Ask which skin warnings are printed on the jar and whether it can go on broken or irritated skin.
- Ask whether the warming ingredient is safe for feet with reduced feeling.
- Show your pharmacist the ingredient list alongside your medicine list.
- Confirm the single-jar shipping cost and the refund steps for a used jar before you pay.
- If you have burning, numbness or tingling in your feet, get the cause checked; a cream treats the surface, not the reason.
