Cognivex Side Effects: What to Know

No Supplement Is Risk-Free

Even natural ingredients can cause side effects or interact with medication. Individual responses vary, and the amounts in Cognivex are not published.

Caffeine From Green Tea

Green Tea Extract can naturally contain some caffeine. People who are sensitive to stimulants may notice jitteriness, a fast heartbeat, restlessness or trouble sleeping, so avoid taking it late in the day.

St. John's Wort and Medications

St. John's Wort is known to interact with many medications, including antidepressants such as SSRIs, birth control, blood thinners, and some transplant and HIV drugs. It can also cause sun sensitivity in some people.

Ginkgo and Bleeding

Ginkgo Biloba may affect bleeding, so people who take blood thinners or have a surgery coming up should ask their doctor first. Mild stomach upset or headache has also been reported with ginkgo.

Who Should Skip It

Do not use if you are pregnant or nursing, under 18, or managing a medical condition unless your doctor agrees. Never stop a prescribed medication to try a supplement.
