- Reviewed in the United States on January 23, 2025Scent: UnscentedSize: 70.4 Ounce (Pack of 1)Verified PurchaseAncient Minerals Magnesium Bath Flakes are a premium alternative to traditional Epsom salts, offering magnesium chloride harvested from the Zechstein seabed for superior purity and effectiveness. Designed to support muscle recovery, stress relief, and magnesium replenishment, these flakes dissolve easily in warm water for a soothing bath experience. I tested them after workouts and on evenings when I needed extra relaxation to assess their performance compared to standard Epsom salts.
Pros:
✅ High Purity Magnesium Chloride: Sourced from the ancient Zechstein seabed, ensuring a natural and highly absorbable magnesium source.
✅ Quick Dissolving: Flakes dissolve much faster than typical Epsom salts, providing an immediate, silky bathwater texture.
✅ Enhanced Muscle Recovery: Provides significant relief from muscle tension and soreness, ideal after intense physical activity.
✅ Gentle on Skin: Leaves the skin feeling soft and moisturized without drying effects, unlike some harsher bath products.
✅ Customizable Doses: Easy to adjust the amount of flakes for mild relaxation or more intense muscle relief.
Cons:
❌ Higher Cost than Epsom Salt: Premium quality comes with a higher price point, making it less budget-friendly for frequent use.
❌ No Fragrance Option: While its unscented formula is great for sensitive users, some may miss the aromatherapy aspect of scented bath products.
Performance and Usability:
The magnesium flakes provided a deeply relaxing bath experience. Compared to Epsom salts, they worked more effectively in relieving post-workout soreness and easing muscle tightness. The skin benefits were also notable, leaving no residue or dryness. The flakes dissolved quickly in warm water, allowing for a hassle-free setup. For regular use, especially after physical exertion or during periods of stress, these flakes proved highly beneficial.
Comparison:
Compared to Epsom salts, Ancient Minerals Magnesium Bath Flakes offer superior magnesium absorption and enhanced relaxation effects, but at a higher cost. While Epsom salts remain a budget-friendly option, the magnesium chloride in these flakes makes them more effective for those needing serious muscle recovery or magnesium replenishment.
Who Is This For?:
This product is ideal for athletes, those with muscle tension, or individuals seeking a more effective alternative to Epsom salts. It’s also well-suited for users with magnesium deficiencies or those looking for a natural way to unwind after a long day.
Conclusion:
Ancient Minerals Magnesium Bath Flakes are a top-tier bathing product for those seeking a relaxing and effective way to replenish magnesium levels. While the cost may be a consideration for some, the exceptional quality, ease of use, and noticeable benefits make it well worth the investment for regular self-care or recovery routines.
- Reviewed in the United States on June 24, 2025Scent: UnscentedSize: 8 Pound (Pack of 1)Verified PurchaseLight and flaky. Dissolve relatively fast once it’s in the water (use your hand to move it around a bit). Doesn’t clog or damage the drains.
Muscle/ body repair: Seems to work fairly well on the body. After use, muscles were super relaxed and sleep was almost instantaneous once I laid down. Woke up the next morning feeling refreshed and even slept in an extra hour or so.
4 of 5 stars: overall good product. Maybe the developer can add a scoop to water mix ratio denoting desired effects on the body. If not, it may take a half bag and some change to receive desired effects.
- Reviewed in the United States on April 28, 2025Scent: UnscentedSize: 26.4 Ounce (Pack of 1)Verified PurchaseThe Ancient Minerals Magnesium Bath Flakes are absolutely worth it if you're serious about getting a high-quality magnesium soak. Unlike standard Epsom salts (which are magnesium sulfate), these are pure magnesium chloride flakes sourced from genuine Zechstein seabed deposits, and you can really feel the difference.
The flakes dissolve quickly in warm water and create a very soothing, therapeutic bath. I find that these help relax my muscles, ease joint stiffness, and even improve my sleep when I soak before bed. The resealable 1.65 lb bag is convenient, keeps everything fresh, and is easy to store.
Compared to regular Epsom salts, I notice a deeper sense of relaxation and less skin dryness after using these. They might be a little pricier, but you’re getting a much higher concentration of bioavailable magnesium, which can really make a difference if you deal with soreness, stress, or magnesium deficiency.
If you're looking for a more effective, cleaner, and more natural alternative to regular bath salts, I highly recommend giving these a try!
- Reviewed in the United States on June 27, 2025Scent: UnscentedSize: 26.4 Ounce (Pack of 1)Verified PurchaseI highly recommend this. I feel better after a nice magnesium salt bath, honestly it’s the only thing that’s gotten me through the stress at work. I believe it has helped my migraines too. I am not a doctor, I just know how I feel when I don’t get to have one. It’s worth a try even if you think it’s fru-fru. My only comment, remember to rinse your tub after I think the residue makes mine more slippy if I don’t.
- Reviewed in the United States on June 2, 2025Scent: UnscentedSize: 8 Pound (Pack of 1)Verified PurchaseAbsolutely phenomenal magnesium flakes. It's advertised as being from the Zechstein beds, and while I thought only one company had a monopoly on magnesium from there, I will say that it mostly likely is a true claim, as this is the best magnesium I've ever used to make my magnesium sprays. Potent, dissolves well, bit of an oily residue but that's normal when mixed with water. Provides incredible pain relief for sore or tight muscles, cramps, and headaches. Also works amazing as a natural deoderant.
- Reviewed in the United States on May 13, 2025Scent: UnscentedSize: 26.4 Ounce (Pack of 1)Verified PurchaseI know magnesium spray has various uses but I saw a video where someone used it to make a deodorant spray with essential oils. That’s why I am using it to avoid the chemicals found in commercial ones and I love it!! It’s natural and doesn’t irritate my skin. It keeps me dry for hours!! I love it!!
- Reviewed in the United States on June 16, 2025Scent: UnscentedSize: 8 Pound (Pack of 1)Verified PurchaseWe use these for sore muscles and it works almost immediately. Very potent, very relaxing.
- Reviewed in the United States on July 10, 2025Scent: UnscentedSize: 26.4 Ounce (Pack of 1)Verified PurchaseWish I could get a huge bag of this! Works great, dissolves easy and made me feel great!

- Tia ParReviewed in Germany on February 15, 2017
5.0 out of 5 stars Great for foot baths and also seasonal consumption
Scent: UnscentedSize: 26.4 Ounce (Pack of 1)Verified PurchaseI made sure I ordered as pure a form as possible because I also drink it to purify the cells of my body. I mix 60g of magnesium chloride with 1 l of water and I drink 200ml of the solution everyday for 5 days. This is a French habit I inherited from my mother and it has always worked a treat for me. I can't guarantee that Ancient Minerals Magnesium Chloride will work for everybody in terms of oral consumption but it does for me, so consume at your own risk! I also use this for my foot baths and it leaves my feet all soft and reenergized. I am just about to reorder a pack actually!
- CasReviewed in Canada on June 8, 2025
5.0 out of 5 stars Amazing and effective
