mSalt is hand-harvested from pristine Icelandic waters, filtered down to 0.03 microns to remove microplastics and contaminants, and evaporated using 100% renewable geothermal energy. Unlike refined table salt, which is stripped of minerals and contains additives, or Himalayan salt, which can contain sedimentary impurities, mSalt retains a balanced mineral profile and is rigorously tested for purity.

Yes. Every batch undergoes independent third-party lab testing to ensure industry-leading low levels of heavy metals and zero microplastic contamination. You can download our Certificate of Analysis (COA) for full transparency.

No. mSalt is a natural sea salt with a clean, unaltered mineral composition. If you require additional iodine in your diet, we recommend the naturally iodine-rich Spirulina found in our mDaily Greens.

For optimal hydration, add a small pinch (about 1/8 tsp) to an 8 oz glass of water. If using a salt brine (sole), start with 1 tsp per 8 oz of water. Adjust based on personal preference and needs.

Yes! The delicate Icelandic flakes are perfect for grinding or used as a finishing salt without grinding.

Keep mSalt in an airtight container in a cool, dry place. If making a salt brine, store in a glass jar in the refrigerator for long-term use.

While both provide essential minerals, mSalt is a pure, naturally balanced sea salt, while mMinerals is a liquid blend designed for targeted mineral replenishment. Learn more in our blog post.

Yes, mSalt can be safely added to a pet’s water or food in small amounts, but always consult your vet for specific dietary recommendations.

Unlike refined table salt, mSalt provides a balanced mineral profile that supports hydration and electrolyte balance. However, if you have specific health conditions, consult your doctor before making dietary changes.

Clear urine may seem like a sign of great hydration, but it can actually indicate that you’re overhydrated and flushing out essential electrolytes—especially sodium. Your body needs a balanced level of minerals to maintain hydration, support energy, and regulate key functions like muscle contractions and nerve signaling.
If your urine is consistently clear, it may be a sign that you’re drinking too much water without replenishing lost minerals. Instead of just increasing water intake, focus on maintaining electrolyte balance by adding a pinch of high-quality, mineral-rich salt like mSalt to your water. This helps your body absorb and retain hydration more effectively without diluting essential nutrients
