Does heat exposure during shipping affect my Magnesium Glycinate?Updated 24 days ago

Thank you for your question, and we completely understand the concern, especially during the warmer months.

Magnesium glycinate is one of the most heat-stable supplements. The magnesium itself isn't affected by the temperatures a package sees in transit, and the mineral bond is sturdy enough that brief heat won't reduce its potency. Our vegetable cellulose capsules and BPA-free, FDA-approved PET bottles are built to handle standard shipping conditions, including a day or two in a warm mailbox.

The things that genuinely affect this product are long-term moisture and sustained high heat over weeks, which is why we recommend storing it in a cool, dry spot once it arrives. A short, warm trip to your door is nothing to worry about.
