Analysis

Fermented cordyceps mycelia leads the formula, supported by rhodiola, eleuthero, chlorella, burdock, and bromelain. The approach is more relevant to broad stamina and stress resilience than acute focus.

Rhodiola names rosavins and salidrosides, but no species or percentages are given. Cordyceps species and active markers are absent, while eleuthero lacks plant-part and eleutheroside detail.

The two-capsule serving carries a relatively high routine cost for several modest additions. People seeking a focused adaptogen would get easier potency comparisons from a standardized single or dual-ingredient formula.

Who is it for
  • Adults seeking caffeine-free stamina support
  • People who prefer multi-herb adaptogens
  • Users comfortable with incomplete marker data
Best for
  • Stress-related fatigue
  • Broad adaptogen support
  • Non-stimulant daily use

Pros

  • Uses fermented cordyceps mycelia
  • Includes rhodiola and eleuthero
  • Lists individual ingredient amounts
  • Avoids a single large proprietary blend

Cons

  • Cordyceps species is not named
  • Rhodiola marker percentages are missing
  • Eleuthero amount and characterization are limited
  • High serving cost

Warnings

  • Bromelain may increase bleeding risk with anticoagulant or antiplatelet medicines
  • Rhodiola may feel activating or disrupt sleep in sensitive users

Nutrient quality

67 High impact

Several extracts are identified, but species, plant parts, and marker percentages are incomplete. Cordyceps is moderate, while eleuthero, Rhodiola, and the secondary ingredients are modest.

.

Ingredient transparency

61 Moderate impact

Most active amounts are stated, but a composite ingredient remains incompletely described. Missing excipient details and complete use directions leave the supplied label information incomplete.

.

Customer satisfaction

63 Moderate impact

The supplied aggregate satisfaction average is favorable, while the response volume determines how stable that signal appears. No comment-level evidence is available to assess repeated complaints or confirm intended-use experiences.

.

Value for money

42 Lower impact

Quality, disclosure, or serving economics materially weaken value. Small chlorella, bromelain, and burdock additions dilute the adaptogen focus.

B- Goal FitD+ Strength of SupportC- CoverageC+ Formula Quality

Rhodiola, cordyceps, and eleuthero aim at stress resilience and fatigue resistance without caffeine. The adaptogen strategy is relevant, though it does not directly cover metabolic cofactors or acute alertness.

Rhodiola markers are named but not quantified as percentages, and the species is missing. Cordyceps and eleuthero are modestly dosed with incomplete identity details, making potency less certain than the ingredient list suggests.

C Goal FitD Strength of SupportD+ CoverageC+ Formula Quality

Rhodiola, eleuthero, and cordyceps may support mental stamina when stress or fatigue drives poor performance. The rhodiola and eleuthero amounts are modest and their active standardization is incomplete.

Cordyceps adds an energy-resilience pathway, while chlorella, burdock, and bromelain contribute little to cognition. The formula may offer gentle adaptogenic support but lacks a direct memory or neurotransmitter active.

C- Goal FitD- Strength of SupportD CoverageC+ Formula Quality

Rhodiola, Eleuthero, and cordyceps may support mental stamina when stress or fatigue interferes with concentration. The adaptogen-centered design is more relevant to resilience than to an immediate increase in attention.

Rhodiola marker compounds are named without percentages or species confirmation, and both Rhodiola and Eleuthero amounts are modest. Several non-focus additions dilute the formula without adding clear cognitive depth.

C Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyF Value

Both marker compounds are listed, but the label does not identify the Rhodiola species. Missing marker percentages further limit confidence in authenticity and standardization. The serving is modest and works better as part of a blend than as a focused Rhodiola dose.

F Active Ingredient Quality & BioavailabilityD- Dose, Safety & Label TransparencyF Value

Fermented Cordyceps mycelia extract offers a credible cultured source, but its species is not named. The 475 mg amount is moderate and no extraction method or active-marker level is disclosed. Above-median serving cost limits value for the available evidence.

Eleuthero · 126 mg OverallScore27
F Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyF Value

The formula states an exact Eleuthero amount but does not identify an extract, plant part, or active standard. Its 126 mg amount is well below the preferred range for an unstandardized herb. A high serving cost compounds the weak Eleuthero-specific fit.

HPA Adapt

Integrative Therapeutics
Large standardized amounts of rhodiola and eleuthero pair with ashwagandha, maca, and holy basil in a more fully specified adaptogen blend. It omits cordyceps and costs slightly more per serving, but its supplied energy, focus, and cognitive analyses are substantially stronger.
72 Performance

Adreset

Metagenics
A much larger cordyceps extract is paired with standardized rhodiola and ginseng, making the energy-oriented core more substantial and transparent. Eleuthero is absent and the serving cost is higher, but the formula aligns more strongly with energy and focus.

Energy

Redd Remedies
Standardized rhodiola is supplied at a larger amount and paired with cordyceps, ginseng, and active-form vitamin B6. Cordyceps remains modest and licorice may not suit everyone, but the supplied goal analyses show stronger energy and focus coverage.
81 Budget

Adrenal Serenity

Natural Factors Stress-Relax
The lower-cost serving keeps rhodiola and eleuthero while adding ashwagandha and lavender in a simpler blend. Marker details are limited, but the supplied analyses show much stronger eleuthero and cognitive-support alignment than the original.

AdrenaSense

Natural Factors WS WomenSense
Standardized rhodiola and eleuthero are supplied at meaningful amounts alongside schisandra and ashwagandha for a lower serving cost. It omits cordyceps, yet provides clearer extract markers and stronger support for energy, focus, and cognition.

SharpMind Energy

Solaray
Rhodiola and fermented Cordyceps militaris retain two core ingredients in a simpler, lower-cost focus formula. The extract standardization is limited, but the reduced serving cost and stronger overall analysis improve the value trade-off.

Phyto-ADR

Pure Encapsulations
Standardized rhodiola and eleuthero are joined by ginseng, ashwagandha, and pantothenic acid at a much lower serving cost. It gives up cordyceps, but clearer marker disclosure and stronger overall quality make the focused blend better value.

LifeSeasons
Standardized rhodiola and eleuthero are paired with green tea, theanine, holy basil, and schisandra for less per serving. The stimulant-containing design differs from the original and the core botanicals are more modest, but its energy alignment and transparency support a reasonable value case.
