Immediate Subjective Effects of the Recharge Portal: A Pilot Study

Introduction

The Recharge Portal integrates five modalities: red light therapy (photobiomodulation), molecular hydrogen inhalation, micro-impact therapy, vagus nerve stimulation with sound therapy, and nano-curcumin supplementation. This pilot study evaluated immediate subjective responses in 21 participants, assessing self-reported well-being, energy, mental clarity, stress, mood, and physical comfort via pre- and post-session surveys.

A prior observation with 12 participants using PNOĒ metabolic analysis reported changes in heart rate variability, energy metabolism, and fat oxidation after a single session. That preliminary data informed the design of this survey-based pilot.

Methods

Twenty-one healthy adults (aged 18–65, no acute medical conditions) were recruited via convenience sampling from individuals who approached for a demo experience and voluntarily completed pre- and post-session surveys. Exclusion criteria included pregnancy, severe neurological disorders, or recent surgery. Participants provided written informed consent under ethics committee guidelines.

Table 1: Subjective Changes Before and After A Single Recharge Portal Session (n=21)

Participants rated four domains on a 1–10 scale before and ten minutes after a 15-minute session: Overall Well-Being, Physical Energy Levels, Mental Clarity & Focus, and Stress & Tension Levels. They also reported Mood & Emotional State and Body Sensations & Discomfort using categorical descriptors. Wilcoxon signed-rank tests compared continuous variables; McNemar's test assessed categorical shifts (α = 0.05).

Results

All six domains showed statistically significant changes following a single session:

• Overall Well-Being increased from 8.2 ± 1.0 to 9.0 ± 0.7 (+9.8%, p = 0.002). Nine participants improved; twelve remained stable; none declined.

• Physical Energy Levels rose from 7.2 ± 1.3 to 8.6 ± 0.8 (+19.4%, p < 0.001). Fourteen participants reported increases; seven remained stable.

• Mental Clarity & Focus improved from 7.6 ± 1.2 to 9.0 ± 0.6 (+18.4%, p < 0.001). Sixteen participants reported improvement; five remained stable.

• Stress & Tension Levels decreased from 4.9 ± 2.4 to 3.3 ± 1.8 (-32.7%, p = 0.001). Seventeen participants reported reductions; four remained stable.

• Mood: Participants reporting "Calm & Centered" increased from 43% (9/21) to 81% (17/21) (+88%, p = 0.008). Of 12 participants not initially calm, 8 (67%) shifted to that category.

• Body Comfort: Participants reporting "No Discomfort" increased from 29% (6/21) to 71% (15/21) (p = 0.004). Of 15 participants with initial discomfort, 9 (60%) reported none post-session.

  
  

Discussion

Participants reported statistically significant subjective improvements across all measured domains following a single 15-minute session. These findings are consistent with proposed physiological mechanisms of the integrated modalities, including vagus nerve stimulation and photobiomodulation.

However, several limitations are important to note. This was a small convenience sample (n=21) of self-selected individuals who approached for a demo experience—a population likely predisposed to report positive outcomes. There was no control or sham condition, making it impossible to isolate device-specific effects from expectation, placebo, or novelty responses. The 10-minute post-session assessment does not indicate whether effects persisted beyond that window. Baseline health status, prior therapy experience, and psychological factors were not controlled for. Ceiling effects (10–24% of participants) and floor effects (19% for stress) also constrained some outcomes.

Plain Language Summary

Most participants reported feeling better after the session—with more energy, clearer thinking, less stress, and reduced physical discomfort. The statistical results suggest these changes were not random. That said, only 21 people participated, all of whom chose to try the device, which means they may have expected to feel better. It is also unknown whether the effects lasted beyond the few minutes following the session.

Conclusion

A single 15-minute Recharge Portal session was associated with statistically significant immediate improvements in self-reported well-being, energy, mental clarity, mood, stress, and physical comfort in this small pilot sample. Larger controlled trials with longer follow-up periods are needed to validate these findings, isolate placebo effects, and assess the duration of any benefits.

This study reflects preliminary pilot data from a small, self-selected convenience sample and is not intended to establish clinical efficacy. Results are not generalizable to broader populations. The Recharge Portal is intended for general wellness use and is not intended to diagnose, treat, cure, or prevent any disease or medical condition. Individual experiences may vary.
