Shopping FAQs

H2HUBB LLC is your trusted hub for all things hydrogen-related, often referred to as the “Amazon of hydrogen” but with much higher standards. We specialize in hydrogen consultation and education, offering expert insights into molecular hydrogen therapy and technology.

What sets us apart is our rigorous H2 product evaluation process. Every product featured on H2HUBB undergoes thorough testing for hydrogen concentration, engineering quality, and overall performance to ensure it meets or exceeds standards rooted in scientific research. Only the highest-performing hydrogen products earn a place on our platform.

We simplify the buying process by helping consumers find safe, verified therapeutic hydrogen products. Additionally, we provide access to these top-tier products through exclusive discounts and links to trusted sellers, ensuring a secure and reliable shopping experience. Whether you’re here to learn, explore, or shop, H2HUBB is dedicated to helping you enhance your health with confidence.

 

No, purchasing an H2 product through H2HUBB is not the same as buying directly from us. Instead, you are purchasing an H2HUBB-approved hydrogen product from a Recommended Product Company (RPC) via a direct link provided on our website.

H2HUBB does not sell products directly. Rather, we serve as a trusted third-party resource for consumers seeking high-quality, therapeutic hydrogen products—especially those that may be difficult to find in the U.S. market.

Our Approved H2 Product Recommendations ensure you can confidently choose a hydrogen product that fits your needs. Each recommended product is sold by an entirely separate company but has been thoroughly tested by H2HUBB—an authority in the industry. This means you can trust that the product is safe, effective, and of the highest quality.

The performance levels indicate the therapeutic potential of a product based on its hydrogen output. Higher levels (e.g., Level 3, 4, 5) reflect greater doses of hydrogen gas consumed per liter of water, which correlates with increased therapeutic potential.

At H2HUBB, these H2 water levels are calculated by measuring the maximum dissolved hydrogen a product can provide in 1 liter of water during our evaluations. The measurement is adjusted to its equivalent mg/L value to determine how many milligrams of hydrogen gas could be ingested in a liter—an industry-standard volume aligned with scientific studies and average daily water consumption.

The performance rating system, ranging from Level 1 to Level 5, is based on hydrogen amounts shown in clinical studies, with daily therapeutic recommendations typically falling between 1–3 mg or more. As the industry evolves, our ratings may adapt to reflect advancements in product performance.

No, H2HUBB does not publicly display every product we have tested. While we have evaluated over 100 hydrogen products and systems, we only feature those that meet our performance standards. These recommended products are highlighted on our site and updated regularly as new products are tested and approved. 

Products that do not meet our standards are not published to protect the professional reputation of the companies involved. This approach allows manufacturers to use our detailed test reports to improve their products without publicly tarnishing their brand. Additionally, some products are removed from our recommendations for reasons such as distribution being discontinued, manufacturers requesting removal to avoid competition, or our decision to dissociate from companies with questionable practices.

Our focus remains on providing consumers with reliable, high-quality hydrogen product recommendations while maintaining integrity and professional courtesy within the industry.

If you’re curious whether we’ve tested a particular hydrogen product, feel free to email us—there’s a good chance it’s already been evaluated.

H2HUBB primarily displays its own independent test results. However, if a product includes prior test results from H2 Analytics—conducted using laboratory-grade equipment—we may publish those alongside our evaluations.

Our published results, such as dissolved hydrogen concentration, are designed to provide consumers with an accurate understanding of a product’s strengths and weaknesses. These results are independent of manufacturers, distributors, or retailers, and may differ due to variables in testing conditions.

Performance levels assigned to recommended products are based solely on H2HUBB’s testing, not on marketing claims. Over the years, our evaluations have consistently proven to be accurate and reliable, offering consumers confidence when selecting a hydrogen product.

First, reach out to the company you purchased the product from and begin a correspondence regarding your concerns.

While H2HUBB aims to minimize the risks associated with purchasing hydrogen products, we understand that no system is foolproof. We strive to reduce uncertainty by thoroughly testing and verifying products through objective, third-party performance analyses. This process helps consumers make more confident purchasing decisions compared to buying blindly.

It’s never great to hear when consumers are dissatisfied with their purchase or feel it didn’t meet their expectations. While most customers have positive experiences with products we recommend, dissatisfaction can still occur. It’s important to note that there are two ways to verify hydrogen product claims:

  1. Through trusted third-party testing – This is where H2HUBB steps in, providing comprehensive evaluations and detailed test reports for every recommended product.
  2. Through personal testing – We aim to alleviate this burden, as most consumers lack the knowledge, skills, or equipment needed to adequately test these products and determine their efficacy.

H2HUBB is not affiliated with the products or companies we recommend. Our focus is strictly on evaluating performance and efficacy against objective standards, not on assessing long-term reliability or corporate ethics. Any concerns related to customer service or product issues should be directed to the specific Recommended Product Company (RPC).

We are committed to supporting consumers in making more informed decisions, even if the process isn’t perfect.

Yes, H2HUBB earns a small percentage of sales from many of our recommended products through accreditation fees. This approach is well-earned because we provide a valuable and credible service that benefits both consumers and companies.

Our recommendations are based on objective third-party testing, connecting honest, good-hearted consumers with reputable companies offering safe and effective hydrogen products. This ensures consumers can confidently purchase therapeutic-grade hydrogen products that meet our performance standards.

In addition, H2HUBB dedicates endless hours to creating fact-based educational content on hydrogen therapy, available for free to the public. These resources, combined with our independent product evaluations, empower consumers to make informed decisions while supporting trustworthy hydrogen companies.

While we acknowledge that earning accreditation fees may not appear completely unbiased, we prioritize transparency and uphold the integrity of our testing. Even products for which we earn no income are included in our recommendations because our ultimate goal is to help consumers access high-quality hydrogen products and drive the industry forward.

At H2HUBB, we believe the value we provide earns this income model, allowing us to remain a trusted authority in hydrogen therapy and product evaluation.
