SAC StudioReliable, organic-labeled sinensis mycelium from a trusted brand — not the cheapest per day, and not the cordycepin-rich militaris form.
NOW Foods Cordyceps is the reliable mainstream value entry, and it comes with an interesting wrinkle: it's organic, cultured Cordyceps sinensis mycelium in the same category the older human exercise trials actually used. NOW is a high-volume brand with in-house and third-party (Intertek) GMP-audited manufacturing and a long record of consistent quality control. The per-capsule price is low (~$0.19), but the label serving is 2 capsules and the directions call for 2 capsules 2 to 3 times daily — so the real cost runs about $0.76–$1.13 a day, and the 90-count bottle lasts roughly 15–22 days at full dosing, not the bargain a single-capsule read suggests.
On this list's terms, though, it sits at #6. It's cultured mycelium of Cordyceps sinensis, grown in culture because real wild sinensis costs more than gold — and it carries lower expected cordycepin than the militaris fruiting body the top picks use, with no beta-glucan number disclosed. That's not a knock on the manufacturing, which is trustworthy and organic-labeled; it's a statement about the lineage and form. A dependable, well-made bottle for a value buyer who budgets for the real label-directed cost — just not the cordycepin-rich extract that defines the top of the list. Here's the breakdown.
Organic Cordyceps sinensis mycelium — not the cordycepin-bearing militaris fruiting body, and the label doesn't print a specific strain name (commercial sinensis mycelium is commonly marketed as 'CS-4', the type the older human trials used). It carries lower expected cordycepin and is mycelium rather than a fruiting-body extract. Respectable and organic-labeled, but a clear tier below the militaris picks on the axis that decides active content.
Not disclosed on the label, and cultured sinensis mycelium carries lower expected active content than a militaris fruiting body. Scored honestly on 'not stated' plus the lineage — not assumed worthless (this sinensis-mycelium category has human exercise data), but clearly behind the picks that disclose beta-glucan figures.
NOW's manufacturing is GMP-audited both in-house and by the third-party auditor Intertek (shown in the product's gallery photos), and the Supplement Facts panel itself declares the cordyceps ingredient 'Organic' — though no USDA Organic seal is visible on the packaging and no COA is published. The product is vegan. Re-scored up from an earlier version of this review, which overlooked the organic ingredient line and the third-party Intertek audit and incorrectly implied NOW sat below the organic-certified picks: a trustworthy, organic-labeled manufacturing story just shy of full COA transparency.
The raw per-capsule price is low (~$0.19), but the label's actual serving is 2 capsules ($0.38) and the directions call for 2 capsules 2 to 3 times daily — 4–6 capsules, or $0.76–$1.13, per day. At that label-directed dose the 90-count bottle lasts only about 15–22 days, and Double Wood and Nutricost pack more servings per dollar for sustained daily use. Re-scored down from an earlier version of this review, which priced the product as if one capsule were a full day's serving. Still reasonably affordable and easy to find — just not the bargain the per-capsule number implies.
Notably, this is the cultured sinensis-mycelium category with actual human exercise data (Chen 2010 tested CS-4 sinensis mycelium — improved sub-maximal thresholds over 12 weeks at roughly 1,000 mg/day, though not VO2max), which is a point in its favour even though the cordycepin content is lower and NOW's labeled dose (3,000–4,500 mg/day) is well above what that trial used. Capped by the mixed evidence and the lower-active-content lineage. A plausible modest support over weeks.
“Organic Cordyceps sinensis mycelium, 750 mg per capsule (1,500 mg per 2-capsule serving).”
Confirmed on the Supplement Facts panel: 'Organic Cordyceps (Cordyceps sinensis) (Mycelium) 1.5 g' per 2-capsule serving, i.e. 750 mg per capsule. Accurate as stated. The label doesn't print a specific strain name like 'CS-4'; this cultured sinensis mycelium is in the same category as the form used in the older human exercise trials (Chen 2010).
“GMP-tested for quality and consistency.”
Consistent with NOW's well-documented in-house GMP testing and long quality-control track record; the product's gallery photos also show a third-party GMP audit by Intertek. The manufacturing reliability is a genuine strength and one of the reasons to choose NOW at this price point.
“Vegan; non-GMO (per retail listing).”
Vegan is confirmed on the label — the front panel reads 'Vegetarian/Vegan,' and the capsule and stearic acid are plant-derived. 'Non-GMO' is not printed on the front, side, or back label itself; it appears only as a retail-listing attribute, so we can't verify it against the physical label and don't mark it label-verified.
“Healthy Immune Support, Free Radical Scavenger, Healthy Vascular Function (label structure/function claims).”
These three claims are printed on the front label, each carrying the required FDA disclaimer asterisk — standard structure/function claims not evaluated by the FDA. Separately, the older human exercise research on this cultured sinensis-mycelium category (Chen 2010) found improved sub-maximal exercise thresholds but no VO2max change — a modest, indirect line of evidence for stamina/endurance that isn't itself printed on NOW's label.
An earlier version of this review said the product had 'flexible single-capsule 750 mg dosing' and priced it at ~$0.19/day, and never mentioned that the label declares the cordyceps ingredient organic. The Supplement Facts panel reads: 'Serving Size 2 Veg Capsules ... Organic Cordyceps (Cordyceps sinensis) (Mycelium) 1.5 g (1,500 mg) ... Servings Per Container 45,' and the back label directs 'Take 2 capsules 2 to 3 times daily' (4-6 capsules, 3,000-4,500 mg/day; roughly $0.76-$1.13/day; the bottle lasts 15-22 days at that dose). We re-read the label on Sep 3, 2026 and revised the Dose spec, the dosing FAQ, the price/value math, the Value per day score (9.0 -> 6.5), and the Purity & third-party testing score (8.5 -> 8.8, crediting the organic ingredient line and the third-party Intertek GMP audit shown in the product photos). Overall score: 7.6 -> 7.3. We also softened unverified 'CS-4' strain and 'non-GMO' references throughout, since neither is printed on the physical label.
An honest point in NOW's favour: the original human cordyceps exercise research was done on cultured sinensis mycelium (commercially marketed as CS-4), not militaris. Chen 2010 gave older adults CS-4 sinensis mycelium for 12 weeks and measured improved sub-maximal metabolic and ventilatory thresholds (though not VO2max). So while this sinensis-mycelium category carries less cordycepin than militaris, it isn't an unstudied form — it has real, if modest and mixed, human data behind it, which is more than can be said for many supplements.
The reason it ranks #6: this is cultured mycelium of Cordyceps sinensis (commercial sinensis mycelium is often marketed under strain names such as CS-4), grown in culture, and it carries little cordycepin — the marker compound that militaris accumulates (Tuli 2014). It's also mycelium rather than a concentrated fruiting-body extract, and the label discloses no beta-glucan number. On the active-content axis that defines the top of the list, it's a clear tier below the militaris fruiting-body picks.
Where NOW delivers is dependability and manufacturing trust: in-house and third-party (Intertek) GMP testing, a 30-plus-year quality-control reputation, an organic-labeled cordyceps ingredient, vegan formulation, and availability at nearly every retailer. But the value case needs the real numbers: the label serving is 2 capsules (not 1), directions call for 2 capsules 2 to 3 times daily, and at that dose a 90-count bottle runs about $0.76-$1.13 a day and lasts only 15-22 days. For a value buyer who understands they're getting cultured sinensis mycelium rather than a concentrated militaris extract — and who budgets for the real label-directed cost — it's a reasonable, low-risk purchase.
Even with this cultured sinensis-mycelium category's human data, the realistic expectation is modest. Chen 2010 found sub-maximal threshold improvements, not a VO2max boost, at a lower dose than NOW's own label directs, and the broader human evidence for cordyceps is limited and mixed. Take it daily for several weeks (the trial ran 12), pair it with actual training, and treat any improvement in exercise economy as a welcome bonus rather than a guaranteed performance jump.
NOW Foods Cordyceps is the dependable mainstream pick, and it carries a genuine point of interest: it's cultured Cordyceps sinensis mycelium, organic-labeled, in the same category the older human exercise trials used. NOW's in-house and third-party (Intertek) GMP testing is reliable, and the per-capsule price is low (~$0.19) — but the label serving is 2 capsules (1,500 mg) and directions call for 2 capsules 2 to 3 times daily, so the real cost runs about $0.76-$1.13 a day and a 90-count bottle lasts roughly 15-22 days at full dosing. For value buyers who budget for that real cost, the manufacturing trust and the organic ingredient line are genuine strengths. It ranks #6 because of lineage and form, not quality of manufacture: it's lower-cordycepin sinensis mycelium, not the militaris fruiting body the top picks use, and no beta-glucan number is disclosed. The honest evidence read is measured too — Chen 2010 found this sinensis-mycelium category improved sub-maximal exercise thresholds over 12 weeks at roughly 1,000 mg/day (lower than NOW's own labeled dose) but not VO2max. So consider NOW if you want an organic-labeled, trusted cordyceps at its real label-directed cost and are fine with the sinensis-mycelium trade; choose a militaris fruiting-body extract (Real Mushrooms #1, FreshCap #2, Nootropics Depot #3) if you want verified, cordycepin-relevant active content. Either way, run it for weeks alongside training and keep expectations realistic.

See it on the list →20 healthy older adults, 12 weeks: CS-4 (Cordyceps sinensis) at 333 mg ×3/day raised the metabolic threshold by 10.5% and ventilatory threshold by 8.5% versus no change on placebo — but VO2max did NOT change. This is the same cultured sinensis-mycelium category as NOW's product, though NOW's label doesn't state the specific strain and directs a higher daily dose (3,000-4,500 mg vs. this trial's ~1,000 mg/day); the evidence is for improved sub-maximal exercise economy, not peak aerobic power.
Cited as the contrast: a Cordyceps militaris blend improved VO2max and time-to-exhaustion after 3 weeks. The stronger endurance signal is on the militaris form, not the sinensis mycelium form NOW uses — the reason militaris fruiting-body extracts rank above sinensis mycelium on this axis.
