Does heat exposure during shipping affect my Magnesium Glycinate?Updated a day 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.
