Real Mushrooms Cordyceps Extract with Beta-Glucans, 120 ct

4.5(4,672)

$34.95

One of the few that prints its beta-glucan content instead of a vague 'mushroom blend'. If the label will not tell you how much active material is in there, you cannot dose it.

Host Defense Cordyceps Capsules

US-grown, single species, organic certified — the best-rated of the three. Cordyceps is graded emerging here: the VO2max signal is real but small and inconsistent.

What to look for

✓Cs-4 fermented mycelium (Cordyceps sinensis), 333 mg capsules; or cultivated C. militaris extract standardised to declared cordycepin (≥2.5 mg/g) and beta-glucans (≥150 mg/g). Never a 'mushroom blend' where the cordyceps dose is unknowable.
✓1 g/day Cs-4 (333 mg × 3) with food; C. militaris trials used 1-4 g/day.
✓Third-party tested (USP, NSF, Informed Sport)

What to avoid

✕Proprietary blends that hide the dose per ingredient
✕Unstandardised extracts with no active-compound percentage

Safety notes

· Wild Cordyceps sinensis is routinely adulterated and has documented heavy-metal (lead, arsenic) contamination — only cultivated C. militaris or Cs-4 fermentate is acceptable.
· GI upset and dry mouth are the most commonly reported effects in trials.
· No human safety data beyond ~16 weeks; none of the five C. militaris trials was at low risk of bias.
