Support Brain Health, Memory & Sleep with Nobiletin

Nobiletin is a polymethoxylated flavone found predominantly in citrus peels. It crosses the blood-brain barrier to deliver potent antioxidant, anti-inflammatory, and circadian-supporting benefits. Research highlights its ability to enhance memory, mood stability, and sleep-wake regulation, making it a versatile nootropic for daily cognitive and metabolic support.

What is Nobiletin?

Nobiletin is a polymethoxylated flavone abundant in citrus peels, particularly in tangerines and oranges. Unlike many flavonoids, it crosses the blood-brain barrier to exert neuroprotective, anti-inflammatory, and circadian-regulating effects.

  • Blood-Brain Barrier Permeable: Delivers direct effects on neural tissues.
  • Anti-Inflammatory: Reduces cytokines and oxidative markers.
  • Circadian Support: Activates BMAL1 and PER2 clock genes.
  • Neuroplasticity: Promotes BDNF, CREB signaling, and synaptogenesis.

Core Nootropic Mechanisms

  • Circadian Gene Activation: Upregulates BMAL1, PER2 to improve sleep-wake cycles.
  • Anti-Inflammatory & Antioxidant: Scavenges free radicals and lowers neuroinflammation.
  • Neurogenesis & Synaptic Plasticity: Increases BDNF/CREB pathways and supports new neuron growth.
  • Dopamine Modulation: Balances dopamine signaling for mood and motivation.
  • CREB/BDNF Activation: Enhances learning and memory consolidation.

Core Benefits

  • Memory & Learning: Strengthens long-term potentiation and retention.
  • Mood & Resilience: Balances neurotransmitters, reducing irritability and stress.
  • Sleep & Circadian Health: Synchronizes biological clock, improving sleep quality and daytime alertness.
  • Neuroprotection: Shields against oxidative and amyloid-induced neuronal damage.

How It Feels

Users report a subtle, cumulative improvement:

  • “I fall asleep more easily and wake up refreshed.”
  • “Calm, focused energy without jitter.”
  • “Sharper memory and less mental fatigue in the evening.”

Clinical Research Summary

  • Circadian Restoration: Restores sleep-wake balance in clock gene-deficient mice.
  • Alzheimer’s Models: Reduces β-amyloid accumulation and cognitive decline.
  • Learning & Memory: Enhances CREB/BDNF signaling, improving retention in rodents.

Recommended Dosage & Usage

Form Suggested Dose
Standard Extract 50–100 mg daily
Citrus Peel Extract 500–1,000 mg daily (standardized to Nobiletin)

Best taken in the morning to align with circadian rhythms and support daytime cognitive performance.

Side Effects & Safety

  • Generally well-tolerated.
  • Possible digestive upset or mild headache.
  • Vivid dreams if taken too late.
  • Avoid with MAOIs or sedatives without medical advice.

Caution: Consult a healthcare provider if pregnant, nursing, or on medication.
