Checking the Expiration Date Before Use

Checking the expiration date on your specific bottle is a simple step worth doing before you start.

What to actually do

Check the expiration date printed on each bottle when your order arrives, and note it somewhere alongside your order confirmation if you've ordered multiple bottles.

Why this matters more given the refrigeration recommendation

Since this formula's own materials recommend refrigeration after opening to protect strain potency, confirming the expiration date on each bottle helps you plan when to open each one within the larger 6-bottle package.
