The Science
You're not tired. Your brain is under-fueled.
By 30, your brain makes 25% less of the chemistry behind focus and attention. That's the fog.
Coffee just masks it. Circuit restores the chemistry your brain is actually missing — so the fog lifts and focus stays on through the whole workday.

Questions, answered
The short version of what you need to know.
How fast will I feel it?
Most people notice clearer mornings in the first few days. Sharper focus and recall build over 2–4 weeks of daily use.
Can I take it with my coffee?
Yes. Many people use Circuit instead of their second or third cup. Take it before 2pm so it doesn't affect your sleep.
Is it safe?
Made in an FDA-registered, cGMP-certified US facility and third-party lab tested. If you're pregnant, nursing, or on medication, check with your doctor first.
How long does one bottle last?
30 days. One capsule a day.
What if it doesn't work for me?
Try it for 30 days. If the fog doesn't lift, email us for a full refund — keep the bottle.
