Chemical Forms

Recommended

Cordyceps militaris fruiting body extract
CS-4 cultured mycelium extract

Avoid

Mycelium-on-grain powder (often diluted by starch)
Unlabeled 'cordyceps complex' blends (species and potency unclear)

Expert Note

Most human trials use CS-4 cultured mycelium or C. militaris extracts, not raw grain-grown biomass. Products that clearly disclose species, mushroom part, and beta-glucan or cordycepin content are more likely to resemble studied materials than cheap starch-heavy powders.

Protocol

Amount

1-3 g

Frequency

Once daily or split into 2 doses

When

Morning or early afternoon with food; if it feels stimulating, avoid taking it close to bedtime.

Condition-Based Dosing

Standardized Cordyceps militaris extract

1000-1500 mg daily— Look for disclosed beta-glucan and, ideally, cordycepin content; trial for 6-8 weeks.

CS-4 cultured mycelium products

2-3 g daily— This is the form used in many older human studies.

Whole mushroom powder or low-concentration products

2-4 g daily— Potency is more variable; higher gram doses are often needed.

Safety & Limits

Upper Safe Limit

No official UL; short-term human studies have used up to 4.5 g/day of CS-4 (highest studied human range).

Cycling

Safe for continuous use

Contraindications

Anticoagulants or antiplatelet drugs — possible additive bleeding risk

Diabetes medications or insulin — may increase hypoglycemia risk

Autoimmune disease, transplant history, or immunosuppressants — immune effects may be undesirable

Pregnancy or breastfeeding — insufficient safety data

Planned surgery — stop 2 weeks before due to possible bleeding or glucose effects

Mushroom allergy — may trigger allergic reactions
