I get asked this all the time: "My legs are tired. I know I need magnesium, but the shelf is full of lotions, creams, sprays and balms. Are they all the same?"
The short answer: No, and the difference matters. Most of them use the same mineral, magnesium chloride. What changes is how much magnesium is in there, how long it stays on your skin, and whether you can really massage it in. A balm made the right way gives magnesium its best chance to work right where you put it.

Key takeaways
- Most magnesium lotions, creams, sprays and balms use the same mineral, magnesium chloride.
- Lab research shows more magnesium gets into the skin when there is more of it and when it stays on the skin longer.
- A well-made balm carries plenty of magnesium, stays put while you massage, and absorbs in completely with no grit or sting.
Why I made a balm
I'm Dr. Doug Strobel, MD, a board-certified neurologist. I made my first balm for my own feet after obstacle races.
When I made Dr. Doug's Magnesium Balm, I had two goals. I wanted as much magnesium as I could fit in. And I wanted it to absorb in completely, with no grit, no sting and no pins-and-needles tingle. Mine is the only magnesium balm formulated by a board-certified neurologist. It's hand-crafted, with eight clean ingredients and nothing synthetic.
What is the difference between magnesium balm and magnesium lotion?
They share a mineral, but they don't work the same way on your skin.
A lotion or cream spreads thin and dries fast. That is handy for covering a lot of skin quickly. A spray is magnesium in water. Many people find sprays sting or itch, or leave a gritty white film as they dry. A balm is firm in the stick or jar and melts with the warmth of your hand. You massage it in, so it stays right on the spot you are working on.
Magnesium balm vs lotion vs spray, side by side
| Magnesium balm | Magnesium lotion or cream | Magnesium spray | |
|---|---|---|---|
| Usual magnesium form | Magnesium chloride | Magnesium chloride (some use other salts) | Magnesium chloride |
| How you use it | Massage in until it disappears | Smooth on and let it dry | Spray on and rub in |
| How it feels | Melts in, no film when made well | Light and creamy | Can sting, itch or feel gritty |
| Stays on the spot | Yes, you work it in | Spreads thin | Runs and dries |
| Best for | Calves, feet, neck and shoulders | Large areas, quick all-over use | Large areas, if it doesn't bother your skin |
| Travel | Twist-up sticks don't leak | Pump bottles and tubes | Bottles can leak |
How do you give magnesium the best chance to work?
Three things matter: how much magnesium there is, how long it stays on, and how well you massage it in.
Lab research on skin found that more magnesium gets into the skin's outer layer when there is more of it in the product and when it stays on longer. Hair follicles, the tiny openings hairs grow from, do much of that work (Chandrasekaran, Magnesium Research, 2016). Studies in people are still small. One 2017 pilot used a cream with only 56 mg of magnesium a day. Its authors called that a low dose and asked for bigger, longer studies (Kass, PLoS ONE, 2017).
That is exactly why I packed as much magnesium into my balm as I could. A balm also stays put while you massage it, so it isn't drying off or dripping away. And the massage itself feels great on tired muscles. It works right where you put it. For more on the research, read does topical magnesium absorb through the skin.
Is magnesium balm greasy?
A well-made balm shouldn't be. It should massage in completely and leave soft skin, not a film.
If a balm feels greasy, you probably used too much. Most people do at first. Start with a thin layer and keep massaging until it disappears. That is where the magic happens.
How do you pick a good magnesium balm?
Look for real magnesium, a short list you can say out loud, and someone who knows what they are doing behind it.
- Magnesium chloride, named plainly. It is the most common form for skin. Epsom salt is magnesium sulfate, and it is mostly used in baths.
- Magnesium near the top of the list. Ingredients are listed roughly by amount. If magnesium is near the very end, there may not be much in there.
- A short, clean, non-toxic list. No synthetic fragrance. Essential oils named plainly.
- A doctor behind the formula. Bonus if a doctor made it and can tell you why each ingredient is there.
Mine has eight ingredients: olive oil, coconut oil, beeswax, shea butter, magnesium chloride, peppermint and lavender essential oils, and vitamin E. It comes as a 2.5 oz twist-up stick, an 8 oz jar and a 0.5 oz mini.
How to use magnesium balm: pick, rub, repeat
Use a thin layer, massage it in until it disappears, and make it a habit.
- Pick your spot. Tired calves, sore feet, a tight neck. Start with a thin layer. You can always add more.
- Rub it in. Cover the spot that bothers you, plus about 5 inches above, below and all the way around it. Massage until it disappears. The magic happens when you massage it in completely.
- Repeat. Any time works: before a run, after a run, at your desk or at bedtime. Skip broken or irritated skin.
Picture the end of a long day. Lights down. Two minutes on your calves, and you're done. No sting, no grit, nothing left on your hands.

Frequently asked questions
Is magnesium balm the same as magnesium lotion?
No. Both usually contain magnesium chloride, but a lotion spreads thin and dries fast, while a balm stays on the spot and is massaged in until it absorbs completely.
Which is better, magnesium balm or magnesium lotion?
No study has compared them head to head. A lotion is good for quick, all-over use. A balm is good for working plenty of magnesium into one spot with a slow massage.
Is magnesium balm greasy?
A well-made magnesium balm should massage in completely with no greasy film. If it feels greasy, use less and keep massaging until it disappears.
Does magnesium lotion or balm absorb through the skin?
Lab research shows magnesium can get into the skin's outer layer, mostly through hair follicles, and more with higher amounts and longer contact. Studies in people are small, so think of either one as working right where you put it.
What is the best non-toxic magnesium lotion or balm?
Look for a short list you can read out loud: magnesium chloride, plant oils and butters, and essential oils named plainly, with no synthetic fragrance. Dr. Doug's Magnesium Balm is non-toxic, with eight clean ingredients and nothing synthetic.
Is magnesium cream the same as magnesium lotion?
Close. A magnesium cream is just a thicker magnesium lotion.
What is magnesium balm good for?
Magnesium balm is made for massaging into one spot: tired calves and feet, a tight neck and shoulders, or a slow leg rub at the end of the day. It works right where you put it.
How do you use magnesium balm?
Put a thin layer on the spot and about 5 inches above, below and around it, then massage until it disappears. Use it any time of day, and skip broken or irritated skin.
