Lion's Mane, Reishi & CBD: The Wellness Combination Worth Knowing

Functional mushrooms and CBD have both surged in popularity — and for good reason. Learn how Lion's Mane, Reishi, and Chaga work, and why pairing them with CBD makes sense.

What Are Functional Mushrooms?

Functional mushrooms are edible fungi used specifically for their therapeutic and adaptogenic properties — as distinct from culinary mushrooms like button or portobello. They've been used in traditional Chinese and Ayurvedic medicine for thousands of years. Western research is now validating many of these traditional uses.

The key bioactive compounds in functional mushrooms include beta-glucans (immune-modulating polysaccharides), triterpenes (anti-inflammatory compounds), and hericenones/erinacines (in Lion's Mane, which stimulate nerve growth factor).

The Big Three

Lion's Mane (Hericium erinaceus)

Lion's Mane is best known for its cognitive support properties. It's the only mushroom known to stimulate nerve growth factor (NGF) synthesis, a protein essential for the growth, maintenance, and repair of neurons.

A 2009 double-blind, placebo-controlled study in Phytotherapy Research found significant improvements in mild cognitive impairment scores in adults taking Lion's Mane extract over 16 weeks. These improvements reversed when supplementation stopped — suggesting an ongoing, maintenance role.

Best for: Focus, memory, mental clarity, and long-term brain health.

Reishi (Ganoderma lucidum)

Called the "mushroom of immortality" in traditional Chinese medicine, Reishi is a powerful adaptogen — helping the body regulate its stress response. It modulates cortisol, supports immune function, and has well-documented anti-inflammatory properties.

Reishi is also used to support sleep quality and liver health. It's typically consumed as an extract (not raw) due to its bitter, woody taste.

Best for: Stress resilience, immune support, sleep quality, recovery.

Chaga (Inonotus obliquus)

Chaga grows on birch trees in cold northern climates — including northern Canada — and has one of the highest known antioxidant ratings of any food. Its primary bioactives are betulinic acid (from the birch host), melanin, and polysaccharides.

Best for: Antioxidant protection, immune function, anti-aging support.

Why Combine Mushrooms with CBD?

CBD and functional mushrooms work through different but complementary mechanisms:

  • CBD works primarily through the endocannabinoid system (ECS), modulating mood, inflammation, sleep, and stress response.
  • Functional mushrooms work through immune receptors, NGF pathways, and the HPA axis (the stress-response system).

Together, they address wellness from multiple angles. A 2020 review in Cannabis and Cannabinoid Research noted growing interest in combining cannabinoids with adaptogens for broader therapeutic effects.

Practically speaking, users report that Lion's Mane + CBD is a popular daytime focus stack, while Reishi + CBD is a popular evening wind-down combination.

Cordyceps (Cordyceps militaris) — The Energy Mushroom

Often overlooked beside the more famous trio above, Cordyceps is increasingly popular among athletes and active individuals. It works primarily by increasing adenosine triphosphate (ATP) production — the molecule your cells use for energy — and improving oxygen utilization.

A 2010 study published in the Journal of Alternative and Complementary Medicine found that Cordyceps supplementation significantly improved VO2 max in older adults. More recent work has looked at its applications in reducing exercise-induced fatigue and supporting cardiovascular efficiency.

Best for: Athletic performance, stamina, energy without stimulants.

How to Combine Mushrooms with CBD — Practical Guide

Dosing and Timing

Getting the combination right matters. Here's how experienced users typically approach it:

Morning focus stack (Lion's Mane + CBD):

  • Take 500mg–1000mg Lion's Mane extract with 20–30mg CBD
  • Best taken with breakfast (the fat in your meal improves CBD absorption)
  • Allow 60–90 minutes before expecting cognitive effects from Lion's Mane

Evening wind-down (Reishi + CBD):

  • Take 500mg Reishi extract with 30–50mg CBD
  • Take 1–2 hours before bed
  • Reishi's adaptogenic effect compounds with CBD's calming properties for deeper, more restful sleep

Performance (Cordyceps + CBD):

  • Take 600mg–1000mg Cordyceps with 20mg CBD approximately 45–60 minutes before exercise
  • The CBD helps manage exercise-induced inflammation; the Cordyceps supports oxygen utilisation and endurance

Immune (Chaga + CBD):

  • Take 500mg–1000mg Chaga extract with 30mg CBD
  • Time doesn't matter as much — consistency over weeks matters more than timing on any given day

Extract Quality: What to Look For

Not all mushroom supplements are created equal. The market is flooded with products that use mycelium on grain — essentially powdered growing medium with very little actual mushroom content. Look for:

  1. Fruiting body extracts — the actual mushroom cap/stem, not the mycelium
  2. Standardized beta-glucan content — at minimum 20% beta-glucans (the active immune compound)
  3. Extraction method — hot water extraction is standard for polysaccharides; dual extraction (hot water + ethanol) is better for triterpenoid-rich mushrooms like Reishi
  4. Third-party lab testing — confirms potency and rules out heavy metals and contamination

At Buy Mellow, our functional mushroom capsules use organically grown fruiting body extract, standardized for beta-glucan content and third-party tested.

Are There Any Side Effects?

Functional mushrooms are well-tolerated by most people, but a few notes:

  • Reishi can cause digestive discomfort in some people at high doses — start with a lower dose if you're sensitive
  • Lion's Mane may cause vivid dreams in some users (typically not unpleasant)
  • Anyone with mushroom allergies should avoid these products
  • If you're on immunosuppressant medications, consult your doctor before using immune-modulating mushrooms like Chaga

CBD itself has a strong safety profile at typical doses, with mild drowsiness, dry mouth, or appetite changes possible at higher doses.
