The generic warning on every supplement label is easy to skip. This formula has specific reasons behind it, and the list is longer than for most.
Absolute exclusions
Anyone under 18. Anyone pregnant, planning pregnancy or breastfeeding - most of these ingredients have no pregnancy safety data, and St. John’s Wort and Ginkgo both have specific concerns. Anyone with a known allergy to any listed ingredient. Anyone with persistent or worsening memory problems who has not had a medical assessment, because several causes are checkable and correctable and a supplement delays finding them.
Medication-based exclusions
Anyone on hormonal contraception - St. John’s Wort can cause contraceptive failure, and this is the interaction people are least aware of. Anyone on anticoagulants or antiplatelets, given both St. John’s Wort and Ginkgo. Anyone on immunosuppressants including ciclosporin or tacrolimus, where transplant rejection has been reported. Anyone on antiretrovirals or certain cancer medicines. Anyone on SSRIs, SNRIs, MAOIs, triptans, tramadol or lithium, given serotonin syndrome risk. Anyone on digoxin, some statins, or certain anticonvulsants. Anyone on thyroid medication, given the carnitine interaction.

See Cognizil PricingCondition-based caution
Bradycardia, asthma or epilepsy, given Huperzine-A's cholinergic activity. Liver or kidney disease, which alters clearance of everything. Bipolar disorder, given the serotonergic component. Scheduled surgery within two weeks, given bleeding risk - stop and tell the surgical team. Photosensitivity or planned significant sun exposure, given St. John’s Wort. And anyone who has had an adverse reaction to any of these botanicals previously.

Verdict
Not appropriate for under-18s, pregnancy or breastfeeding, or anyone on a long list of common medications including hormonal contraception. The St. John's Wort content makes a pharmacist check necessary rather than optional.
