The Best Combinations with Legal Nootropics: L-Theanine, Lion’s Mane, Niacin (Extended Stamets Protocol) + Micro/Macro Dosing to Maximize Benefits Without Extra Risks

Publication Date: February 2026

In the ever-evolving world of cognitive optimization and mental health, nootropics have become powerful tools for improving focus, memory, mood, and overall well-being. While synthetic nootropics have their place, there is growing interest in natural and legal options that offer sustainable benefits with minimal side effects.

In this in-depth article, we explore the most effective combinations involving L-Theanine, Lion’s Mane (lion’s mane mushroom), niacin (vitamin B3), and psilocybin (present in magic truffles, legal in some countries), with a focus on the extended Stamets Protocol. We cover microdosing and macrodosing, synergies, science-backed benefits, and ways to minimize risks.

The Main Ingredients and Their Individual Benefits

1. L-Theanine – Focused Relaxation

L-Theanine is an amino acid found in green tea. It promotes relaxation without sedation, increases alpha brain waves, and reduces anxiety. It pairs perfectly with stimulants, smoothing out jitters and improving sustained focus. Common dose: 200–400 mg.

2. Lion’s Mane (Hericium erinaceus) – Neurogenesis Stimulator

This medicinal mushroom stimulates the production of NGF (nerve growth factor), promoting the birth of new neurons and brain repair. Studies show improvements in memory, reduction of mild anxiety, and long-term brain health support. Typical dose: 1–3 g of powder or 100–300 mg of extract.

3. Niacin (Vitamin B3) – Cerebral Circulation Enhancer

Niacin causes vasodilation (the famous “flush”), improving blood flow and nutrient delivery to the brain. In the Stamets protocol, it helps distribute psilocybin and Lion’s Mane more effectively. Usual stack dose: 50–200 mg.

4. Psilocybin (from Magic Truffles) – Neuroplasticity Catalyst

Psilocybin promotes neuroplasticity, increases brain connectivity, and can provide lasting relief from depression and anxiety. Microdose (0.1–0.3 g dry equivalent) improves mood and creativity without hallucinations; macrodose (1–3 g dry) delivers transformative experiences.

The Original Stamets Protocol and the Extended Version

The classic Stamets Protocol combines:

• Psilocybin microdose
• Lion’s Mane
• Niacin

Typical cycle: 4 days on / 3 days off, for 4–8 weeks.

In the extended version discussed here, we add L-Theanine to reduce anxiety and improve the smoothness of the experience, allowing both micro and macro doses in a safer and more balanced way.
