Benefits
Enhanced blood flow following resistance exercise
A 2020 randomized double-blind placebo-controlled trial at Auburn University's School of Kinesiology evaluated 300 mg, 600 mg, and 900 mg doses of cellflo6. The 600 mg dose conferred significant circulation benefits following resistance exercise — the first evidence suggesting a green tea-based supplement enhances localized blood flow post-resistance training. Published in the Journal of the International Society of Sports Nutrition.
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). Used in recovery formulations including those used by Tier 1 U.S. Military Operators (Seal Team 6) after rigorous science vetting by Johns Hopkins.
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. Featured in 7-Eleven's 7-Select Fusion Energy beverage sold at over 30,000 retail outlets.
Endothelial function support
cellflo6 is patented (US 11,766,422 B2) for treating endovascular dysfunction and increasing blood flow. Galloylated procyanidins support nitric oxide pathway function and vascular endothelium — the single-cell-layer lining of blood vessels that controls vasodilation. Mechanism relevant beyond exercise to cardiovascular health applications.
Consumer-reported endurance, strength, energy
A 2024 online consumer survey of U.S. men aged 25-46 (74% had been using cellflo6 for 6+ months) reported benefits including improved endurance, strength, energy, recovery, mental sharpness, and general well-being. The subjective benefits align with the documented blood flow mechanism — better circulation supports oxygen and nutrient delivery throughout the body.
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 mechanism explains the enhanced post-exercise blood flow documented in the Auburn study, supporting muscle pump and nutrient delivery during and after training.
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.
Adults performing resistance exercise. Dose-comparison protocol.
600 mg cellflo6 conferred significant circulation benefits following resistance exercise — the first evidence suggesting a green tea-based supplement enhances localized blood flow post-resistance training. Established 600 mg/day as the effective clinical dose. The 900 mg dose did not provide additional benefit over 600 mg. Foundation for subsequent commercial positioning in sports nutrition and men's health formulations.
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.
Following rigorous science vetting by the military's nutrition team at Johns Hopkins, members of Seal Team 6 trained with Proximity Nutrition's cellflo6-powered product. Real-world performance validation in one of the most demanding human performance environments (US Tier 1 Special Operations Forces).
Members of US Tier 1 Special Operations Forces (Seal Team 6).
Tier 1 Operators reported improved performance and recovery using cellflo6-containing products. The military validation provides independent confirmation of subjective effects beyond manufacturer-funded research. Tier 1 SOF performance demands are among the most extreme — anything that produces measurable benefit in that population is likely to transfer to civilian athletic populations.
