Nootropic profile
Artichoke Extract
Artichoke extract supplies luteolin, a flavonoid that inhibits PDE4 to increase cAMP levels in the brain. This mechanism supports memory consolidation, mental clarity, and long-term potentiation - often stacked with forskolin for synergistic effects on learning.

What is Artichoke Extract?
Artichoke extract (from Cynara scolymus) has gained attention in the nootropic community primarily for its luteolin content - a naturally occurring flavonoid that acts as a phosphodiesterase-4 (PDE4) inhibitor.

How to take it
- Typical dose: 500–900 mg per day of standardised artichoke extract
- For cognitive support: 500 mg daily, standardised to contain at least 5% cynarin or luteolin content
- CILTEP stack: 900 mg artichoke extract + 4 mg forskolin, taken on an empty stomach in the morning
- Best taken: In the morning on an empty stomach for optimal absorption
- Onset: Effects may take 1–2 weeks of consistent use to become noticeable
Watch out for
- Side effects: Generally safe. Possible mild GI discomfort, bloating, or allergic reactions in people sensitive to plants in the Asteraceae family (daisies,...
- Allergies: Avoid if allergic to artichoke, daisies, marigolds, or similar plants.
- Bile duct obstruction: May worsen symptoms in people with gallstones or bile duct blockage due to choleretic (bile-stimulating) effects.
- Drug interactions: May interact with cholesterol-lowering medications and blood thinners. Consult a doctor if on medication.
- Pregnancy: Generally considered safe in food amounts; supplemental doses lack sufficient data.
The science, if you're curious.
- Luteolin in artichoke extract inhibits phosphodiesterase-4, preventing the breakdown of cAMP in neurons and supporting sustained intracellular signalling.
- Elevated cAMP activates protein kinase A (PKA) and subsequently CREB, which drives gene expression for synaptic plasticity and long-term memory consolidation.
- Luteolin and other polyphenols in artichoke extract reduce neuroinflammation by inhibiting NF-kB and pro-inflammatory cytokines.
- Rich in chlorogenic acid, cynarin, and flavonoids that protect neurons from oxidative damage.
Where to find it
- Globe artichoke: (Cynara scolymus) - the common culinary artichoke is the primary source
- Supplements: Available as standardised capsules and tablets. Look for products standardised to cynarin or luteolin content.
- CILTEP formulations: Pre-made stacks combining artichoke extract with forskolin are commercially available
