Blood Flow, Oxygen, and Pace: How LIBIO's Circulation Ingredients Can Support Male Runners

Disclaimer: Education only. Not medical advice, not an anti-doping guarantee. Athletes are always under strict liability for what they take.

1. Performance is circulation, not just shoes

Runners obsess over:

• Shoes
• VO₂max
• Interval splits
• Nutrition

All of that matters. But underneath, every stride depends on one core system: Your blood flow.

When you run:

• Your muscles demand oxygen and nutrients
• Your heart must pump efficiently
• Your vessels need to open quickly and appropriately

If that vascular system is sluggish or damaged, your pace and your recovery both suffer—no matter how expensive your shoes are.

2. Nitric oxide: the invisible engine

The body uses a small signaling molecule called nitric oxide (NO) to regulate blood flow.

When you start running:

• Local muscles use oxygen and produce metabolites.
• Endothelial cells and nerves release NO.
• NO tells smooth muscle in vessel walls to relax.
• Blood vessels dilate, delivering more oxygen and nutrients to where they're needed.

Same NO system:

• Supports endurance performance (oxygen delivery, lactate clearance)
• Protects heart and brain vessels
• Drives penile blood flow and erections

So when we talk about NO, we are talking about race performance + heart health + sexual function using the same physiology.

3. LIBIO's circulation cluster: what's inside, in plain language

LIBIO wasn't originally built "for runners," but it was built around this NO/vascular story for men. That makes it highly relevant to endurance athletes.

Key circulation-related ingredients (per day, 2 capsules):

• L-Arginine – 240 mg – NO precursor: substrate for nitric oxide synthase
• Black Galingale (Kaempferia parviflora) Extract – 20 mg – Thai root with data on endurance and antifatigue
• Panax Ginseng Extract – 180 mg – Adaptogen; small-to-moderate antifatigue and circulation effects
• Ginkgo Leaf Extract – 100 mg – Microcirculation and antioxidant support
• Tomato Extract (Lycopene source) – 20 mg – Antioxidant & endothelial-supportive carotenoid
• Cranberry Extract – 20 mg – Polyphenols with evidence in runners and vascular/urinary health

All at low, "daily support" doses, not treatment-level megadoses.

4. What the science suggests for runners

4.1 L-Arginine & NO

Trials using higher doses (1.5–5 g/day) of L-arginine in endurance and clinical contexts show:

• Improved endothelial function
• Modest improvements in time to exhaustion and running economy in some studies, especially in less-trained individuals.

LIBIO's 240 mg/day is about 6–20× lower than those trials—designed as background NO support, not as a standalone ergogenic dose.

4.2 Black Galingale (Thai black ginger)

RCTs in athletes (e.g., soccer players) supplementing ~180 mg/day have shown:

• Improved cardiovascular endurance
• Better muscular endurance and balance
• Reduced perceived fatigue in some protocols

LIBIO's 20 mg/day is substantially lower—again, a tonic contribution, not a full sports-therapy dose.

4.3 Ginseng & Ginkgo

• Ginseng: meta-analyses show small-to-moderate reductions in fatigue and possible improvements in aerobic capacity in some cohorts.
• Ginkgo: long history in microcirculation and cognitive support; effects on running specifically are less direct but plausible via circulation and antioxidant actions.

Together, ginseng + ginkgo support macro and microcirculation and help with central fatigue.

4.4 Cranberry & Lycopene – beyond UTIs

Cranberry: a 2023 trial in trained runners found that 28 days of cranberry extract:

• Improved 1500 m performance (~1.5% faster)
• Reduced post-exercise lactate
• Improved muscle oxygenation indices

Lycopene: human trials show improved endothelial function (better flow-mediated dilation) and reduced oxidative stress after supplementation.

At LIBIO's low doses, they act as daily polyphenol/antioxidant support for vessels and recovery.

5. WADA-awareness and safety for athletes

Reality check:

• WADA does not "approve" supplements.
• Studies show that 10–35% of sports supplements may contain WADA-prohibited substances, often not on the label.

LIBIO is designed to be low-risk from a category perspective:

• Ingredients = amino acids, zinc, mushrooms, herbs, fruit/plant extracts
• No hormones
• No prohormones
• No SARMs
• No stimulant cocktails

But strict liability still applies:

Every athlete is responsible for what they take. No supplement is ever 0% risk.

We encourage competitive athletes to:

• Read anti-doping rules
• Prefer third-party-tested batches if possible
• Make a conscious risk–benefit decision

6. How to think about LIBIO if you're a male runner

What LIBIO is not:

• Not a pre-workout
• Not a nitric oxide mega-booster
• Not a replacement for training, nutrition or sleep
• Not a "legal EPO"

What it is:

A low-dose, multi-ingredient male support stack aimed at:

• Vascular/NO support
• Recovery and stress handling
• Micronutrient and antioxidant support

For a male runner who:

• Trains regularly
• Cares about heart, brain, and sexual health
• Wants long-term performance, not just a 1-day PR

…LIBIO is best thought of as:

A circulation and recovery bias in your favor, layered on top of smart training, good shoes, and real food.
