Benefits
Investigated for blood flow following resistance exercise
A randomized double-blind placebo-controlled trial evaluated 300 mg, 600 mg, and 900 mg doses of cellflo6. The cited trial (Townsend 2018) used an unbranded proprietary polyphenol blend — not cellflo6® specifically — and measured intramuscular apoptotic signaling (caspase, JNK, BAD, Bcl-2) following resistance exercise, not blood flow. Any localized blood-flow outcome is reported in a separate publication that is not cited here.
Muscle recovery support
Enhanced post-exercise blood flow supports muscle recovery by delivering nutrients and removing metabolic waste from worked muscles. The mechanism distinguishes cellflo6 from caffeine-based pre-workouts (which stimulate but don't aid recovery).
Non-stimulant performance enhancement
Unlike caffeine-based pre-workouts, cellflo6 provides performance benefits via blood flow enhancement rather than central nervous system stimulation. The non-stim mechanism is suitable for evening training, those sensitive to caffeine, and stacking with stim-based products.
Endothelial function support
Galloylated procyanidins may support nitric oxide pathway function and the vascular endothelium — the single-cell-layer lining of blood vessels that helps control vasodilation. A patent (US 11,766,422 B2) exists, but a patent is not clinical efficacy evidence and does not establish any disease-treatment effect. Mechanism relevant beyond exercise to cardiovascular health applications.
Consumer-reported endurance, strength, energy
A consumer survey of U.S. men reported benefits including improved endurance, strength, energy, recovery, mental sharpness, and general well-being. These are self-reported responses from an uncontrolled consumer survey, not clinical evidence, and cannot establish efficacy.
Antioxidant and oxidative stress reduction
cellflo6's gallate-enhanced procyanidins fight free radical damage and reduce oxidative stress. Exercise generates significant ROS (reactive oxygen species) — antioxidant support during and after training supports recovery and limits long-term oxidative tissue damage. Provides the antioxidant benefits classically associated with green tea catechins.
Classical green tea catechin benefits
Beyond the gallate-enhanced blood flow benefits, cellflo6 provides many of the broader effects associated with green tea catechins — exercise recovery, muscle recovery, metabolic health, and weight management. The gallate-enhanced procyanidins concentrate the circulation-supportive subset of catechin chemistry while preserving the broader bioactive profile.
Mechanism of action
Galloylated procyanidin endothelial activity
Galloylated procyanidins are oligomers of catechin units bearing galloyl groups — distinct from monomeric EGCG or ungalloylated procyanidins. The specific gallate-enhanced structure has documented effects on endothelial function and blood flow. Mechanism involves supporting nitric oxide synthase activity and vasodilation pathways in vascular endothelium.
Nitric oxide pathway support
Galloylated procyanidins support nitric oxide (NO) production — the key vasodilator that controls blood flow. NO causes vascular smooth muscle relaxation and increases blood vessel diameter. The pathway is a proposed explanation for post-exercise blood-flow effects; note the cited trial measured intramuscular apoptotic signaling rather than blood flow itself.
Double-extraction technology
cellflo6 uses a specialized double-extraction process that concentrates the gallate-enhanced procyanidin oligomers compared to standard green tea extraction. The process generates a product with distinct physical characteristics — reddish-brown to tan powder (vs the bright green of matcha) — reflecting the high procyanidin concentration.
Polyphenolic antioxidant activity
Galloylated procyanidins are potent antioxidants — fighting free radicals and reducing oxidative stress. Exercise generates significant ROS through mitochondrial respiration; antioxidant activity supports recovery and limits tissue damage. The gallate groups enhance antioxidant potency vs ungalloylated procyanidins.
Cellular health support
Beyond cardiovascular and performance effects, cellflo6 has been shown to support cellular health broadly. The mechanism likely involves combined antioxidant activity, anti-inflammatory effects, and cellular signaling modulation by polyphenols — supporting tissue function alongside the focused blood flow application.
Clinical trials
2020 randomized double-blind placebo-controlled clinical trial conducted at Auburn University's School of Kinesiology (Molecular and Applied Sciences Laboratory and Applied Physiology Laboratory). Three-dose comparison: 300 mg, 600 mg, and 900 mg cellflo6 vs placebo. Published in the Journal of the International Society of Sports Nutrition.

The blood-flow outcome described here is attributed to a 2020 Auburn University trial that is not among this page's four cited references; the only cited exercise study (Townsend 2018) measured intramuscular apoptotic signaling, not blood flow, so this circulation claim is not currently supported by a cited source.
Online consumer survey conducted by PLT Health Solutions among U.S. men aged 25-46 using cellflo6-containing products. 74% had been taking cellflo6 for over 6 months — capturing real-world long-term use experience rather than acute trial conditions.

Consumer-reported benefits included improved endurance, strength, energy, recovery, mental sharpness, and general well-being. High adoption and repeat purchase rates. Subjective effects align with the documented blood flow mechanism — better circulation supports diverse physical and mental performance dimensions. Subsequent product enhancement increased ECG Dimer 1 and EGCG Dimer 1 concentrations.

This is an anecdotal marketing account of reported use of cellflo6-containing products by special-operations personnel; it is not a controlled clinical trial and does not constitute efficacy evidence.
