Branded greens, PeakO2® mushrooms, and fruit phytonutrients for active recovery
$24.99 $0.83/servingA performance-oriented greens powder built for active users, not just general wellness. It combines a 2g branded greens base with 1g PeakO2® for daily plant support plus better work-capacity potential. The formula stands out by pairing greens with a researched mushroom performance ingredient.

Phytoactive Max does not cover the phosphocreatine side of performance nutrition, so adding creatine fills a major foundational gap. Creatine supports rapid ATP regeneration, while PeakO2® supports oxygen use and fatigue management, giving you both high-energy output support and broader work-capacity support.
Take daily at any time; with or separate from this product is fine
This formula helps with greens, phytonutrients, and resilience, but it is not a muscle-repair product. Pairing it with a quality protein powder creates a more complete daily recovery system by covering both micronutrient/phytonutrient support and amino acid delivery for muscle repair.
Use protein post-workout or whenever needed to meet daily intake; take this product anytime daily
PeakO2® supports oxygen utilization and endurance-related performance, but hydration status still determines how well you sustain output. Adding electrolytes is especially smart for users doing high-volume training, conditioning, or hot-weather sessions where fluid and mineral losses can become the limiting factor.
Use electrolytes around training; take this product earlier in the day or pre-training
Phytoactive Max is not built to create acute energy, focus, or pump on its own. Pairing it with a pre-workout that provides citrulline, beta-alanine, or moderate caffeine lets this greens product cover daily support while the pre-workout handles the immediate training session demands.
Take the pre-workout 20-30 minutes pre-training; use this daily at a consistent time
Likely stronger as a broad-spectrum daily greens formula if your priority is overall wellness coverage.
Both target daily greens support, but Phytoactive Max has a more explicit performance angle.
Phytoactive Max stands out by including 1g PeakO2® for more training-oriented positioning.
Both appeal to active users, with the choice depending on whether you want branding breadth or PeakO2® emphasis.

Performax | Phytoactive Max | Active Greens Powder is positioned as an active-lifestyle greens formula rather than a kitchen-sink superfood product. The formulation strategy is clear: combine a branded greens base for broad-spectrum plant support, a performance-oriented mushroom complex, and a concentrated fruit phytonutrient component. That gives this product a different identity from basic greens powders that focus only on digestion or alkalinity language without bringing anything meaningful to training capacity.
The foundation is Green Balance® at 2g, a Bio-Botanica branded greens blend described here as an organic and synergistic alkaline superfood complex. Because the full composition is not disclosed in the available verified data, the honest assessment is that Green Balance® gives this formula a branded raw-material advantage, but not the ingredient-by-ingredient transparency of a fully itemized greens panel. In practical terms, this is the daily "coverage" portion of the formula—concentrated greens intended to support micronutrient and phytonutrient intake, antioxidant status, and general wellness support for athletes whose food quality varies across the week.
The standout performance ingredient is PeakO2® at 1g. PeakO2® is one of the most established mushroom performance ingredients in sports nutrition: an organic-certified blend of six mushrooms designed to improve oxygen utilization, support ATP production, lower blood lactate, and delay fatigue. Its bioactive compounds—especially beta-glucans and polysaccharides—also support gut and immune health through prebiotic and immunomodulatory activity. Research on PeakO2® is genuinely strong for a mushroom ingredient, with university-level studies showing improvements in power output, VO2 max, and time to exhaustion, particularly when used consistently. The catch is dose context: the published clinical range is 2-4g daily, and this formula provides 1g. That means it is a meaningful inclusion, especially for daily use and stacking with other performance basics, but it sits below the range most often used in the strongest ergogenic trials.
PhytoServ® at 70mg adds a concentrated fruit phytonutrient component. This ingredient is built around soluble compounds extracted from whole fruits to help neutralize reactive oxygen species and support endogenous antioxidant defenses. For active users, that matters because training itself creates oxidative stress; the goal is not to blunt adaptation, but to support recovery capacity and cellular resilience. Here again, dose honesty matters: the provided amount is below the 200-300mg range often cited for the ingredient’s intended use. So while PhytoServ® is a smart premium inclusion and helps elevate the formula above generic greens products, this specific dose is better understood as supportive rather than fully built out.
As a system, the formula aims to cover three lanes at once: daily greens support, training-relevant oxygen and fatigue management, and antioxidant/phytonutrient density. Green Balance® handles the broad-spectrum plant base, PeakO2® brings the most direct performance angle, and PhytoServ® rounds out the formula with fruit-derived antioxidant compounds. That creates a more athletic use-case than standard greens powders, especially for users who want one daily product that nods toward both wellness and performance.
Transparency is mixed but better than many category products. The branded actives and their doses are disclosed, which is a real plus. However, Green Balance® remains a branded blend rather than a fully itemized greens panel, and the available product data does not include a complete verified Supplement Facts image or serving information. So the ingredient identity is credible, but full-label transparency is not perfect.
What should you expect? On day 1, this is not a stimulant-like experience—it is a daily-use product, not an acute jolt formula. Over the first week, expect it to function more as nutritional insurance and a consistency tool. Over 2-4 weeks of daily use, PeakO2® is the ingredient most likely to show itself subjectively through improved work capacity, easier breathing during conditioning, and better tolerance for repeated training efforts, even if the 1g dose is more conservative than the clinical sweet spot.
PeakO2® is a mushroom-derived performance complex studied for its effects on aerobic efficiency and exercise tolerance. Mechanistically, the blend appears to support oxygen utilization and mitochondrial energy output, which can improve submaximal work capacity over time. The practical implication is not an acute stimulant sensation, but better repeat-effort tolerance with consistent daily use. Its evidence base is still modest, but it is more performance-relevant than decorative mushroom inclusions in many greens products.
Research on PeakO2® suggests benefits may involve reduced relative metabolic strain during training, including improved fatigue resistance and more favorable lactate handling. That matters most for circuits, intervals, mixed-modal conditioning, and longer hypertrophy sessions where oxygen demand accumulates. At 1 gram, this formula reaches the lower clinically studied range rather than the more aggressive upper end. Users should think cumulative adaptation, not immediate ergogenic fireworks.
Concentrated greens blends are best understood as dietary insurance rather than replacements for whole vegetables. Their primary role is to provide a more reliable intake of plant-derived compounds when real-world food quality is inconsistent. In athlete use-cases, that means supporting baseline nutritional habits and routine adherence, especially during busy workweeks. The value depends heavily on ingredient quality and formula identity rather than simply listing more plants.
Fruit-derived phytonutrient concentrates are included to broaden polyphenol exposure and add antioxidant support. These compounds can help modulate oxidative stress signaling, though outcomes depend greatly on dose, extract standardization, and the training context. In this formula, the fruit component is conceptually supportive but quantitatively modest versus stand-alone clinical reds or fruit blends. It is best viewed as a complementary layer, not a primary performance driver.
