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 gradual timeline

Since this formula's own materials describe gut-brain signaling building gradually over 4 to 8 weeks, confirming the expiration date gives you enough runway to actually use the full package before it lapses.
