Who We Are

Lumen Guide is an independent website dedicated to publishing evidence-based reviews, guides, and comparisons related to metabolism tracking, metabolic flexibility, and related health topics. We are not affiliated with, endorsed by, or operated by Lumen Metabolic Inc. or any other device manufacturer reviewed on this site.

Affiliate Relationship Disclosure

Lumen Guide participates in affiliate marketing programs. This means that when you click on certain links on this site and make a purchase, we may receive a commission from the merchant at no additional cost to you. The purchase price you pay is identical to what you would pay by visiting the merchant directly.

Links to products on this site that may result in a commission are clearly marked with language such as "Buy on Lumen," "Check Price," or "Get Lumen." In compliance with the Federal Trade Commission's guidelines on endorsements and testimonials (16 CFR Part 255), this disclosure is placed prominently on this page and in a banner on each article page.

Our Editorial Independence Policy

Affiliate commissions do not influence our editorial content. Our reviews, ratings, and recommendations are based on independent research, personal testing, and publicly available data. Products are evaluated on their merits. Negative findings are reported accurately even when a product generates affiliate revenue.

Specifically:

• We do not accept payment for positive reviews or editorial coverage.
• We do not accept free products in exchange for favorable reviews. If we test a device obtained for free, we disclose this on the relevant review page.
• Star ratings and rankings reflect our honest assessment of each product.
• We update our content when products change or new data becomes available, regardless of affiliate impact.

Third-Party Affiliates We Work With

At present, Lumen Guide earns commissions through affiliate programs related to metabolism tracking and health devices. The specific affiliate partner through which Lumen purchases are tracked is a performance marketing network. We do not control the pricing, promotions, or terms offered by any merchant.

Sponsored Content

Lumen Guide does not currently publish sponsored posts or paid editorial placements. All articles on this site represent independent editorial content produced by the Lumen Guide team. If this policy changes, sponsored content will be clearly labeled as "Sponsored" at the top of the relevant page.

Amazon Associates

Lumen Guide is not currently a participant in the Amazon Associates program. Any links to Amazon products on this site, if present, are not affiliate links.
