Protoflow Editorial Standards: How We Source, Check and Correct Our Pages

Our sourcing has three tiers. The first is the Protoflow label, read line by line from the bottle image. The second is the seller's sales page, read on October 19, 2026 (Protoflow sales page) (Protoflow sales page: packs). The third is outside research: NIH fact sheets, FDA and FTC guidance, NHS and Mayo Clinic pages, and peer-reviewed trials.

Each outside source gets a numbered note. Before a number goes on a page, we read the source and write down what it supports. If a source says "little or no benefit", the page says that. We do not stretch a study past its own conclusion.

Goprotoflow is a licensed U.S. retail desk for Protoflow. We earn money when a reader orders through our buttons, so we have a material connection to the product. Readers have a right to know it, and the FTC reviews rule requires insiders to disclose it (FTC, Consumer Reviews Rule Q&A).

We publish no star rating, review count or buyer quote until a review is matched to a real order and the buyer agrees. The eight review photos on the site came from the vendor, and they sit in empty cards. See the reviews page.

No medical reviewer is named yet, so pages say "Written by the Protoflow label desk". The about page explains who runs the site.

Every page shows its last-updated date. We re-read the sales page for price, pack, shipping and guarantee changes, and we re-check the sources behind any page whose facts moved. A change in a price or term gets a dated note.

To report an error, email [email protected] (Mon-Fri 9:00am-5:00pm ET) with the page, the line and a source if you have one. We reply, check the claim against the label or the source, and correct it when it is wrong. That inbox cannot see orders. For an order you have placed, call +1 (651) 610-1515.

NCCIH advises that "natural" does not mean safe and that labels may not match the contents (NCCIH, Using Dietary Supplements Wisely). FDA does not approve supplements before sale (FDA, Dietary Supplements Q&A).

1. Questions and Answers on Dietary Supplements. U.S. Food and Drug Administration, 2026.Under the Dietary Supplement Health and Education Act of 1994, FDA does not approve supplements or their labeling before they are sold; manufacturers and distributors have the initial responsibility for safety, and FDA acts after products reach the market. Firms that make, package or hold supplements must follow current good manufacturing practices, and serious adverse events must be reported to FDA. Structure/function claims need substantiation and the label disclaimer 'This statement has not been evaluated by the Food and Drug Administration', plus the statement that the product is not intended to diagnose, treat, cure or prevent any disease. Content current as of August 27, 2026.
2. Health Products Compliance Guidance. Federal Trade Commission, 2022.Published December 20, 2022, replacing the 1998 dietary supplements advertising guide. Health benefit and safety claims generally require 'competent and reliable scientific evidence' held before the ad runs, and randomized, controlled human trials are the most reliable support. A testimonial that honestly reflects a user's experience does not by itself substantiate effectiveness, unusually dramatic results are likely deceptive, and 'results not typical' disclaimers do not cure that. A DSHEA disclaimer does not cure an otherwise deceptive claim, and endorsers' material connections, such as payment, must be clearly disclosed. The guidance is non-binding and gives no safe harbor.
3. The Consumer Reviews and Testimonials Rule: Questions and Answers. Federal Trade Commission, 2024.The Rule on the Use of Consumer Reviews and Testimonials (16 CFR Part 465) took effect October 21, 2024, and authorizes courts to impose civil penalties for knowing violations. Section 465.5 requires insider reviews and testimonials to clearly and conspicuously disclose the material connection, and a disclosure in the first line of a review qualifies while a hyperlink alone may not. Section 465.6 bars a business from misrepresenting that a website it controls provides independent reviews or opinions, and a contradictory disclosure will not cure an express claim of independence. The page gives no dollar penalty figure.
4. Using Dietary Supplements Wisely. National Center for Complementary and Integrative Health (NIH), 2019.'Natural' does not always mean safe; supplements can interact with medicines or make them less effective, some may increase bleeding risk or affect anesthesia, and about 23,000 emergency room visits per year are linked to them. The label may not match what is in the product, and terms like 'standardized', 'verified' or 'certified' do not necessarily guarantee quality. The FDA generally cannot review supplements for safety or effectiveness before they are marketed and can act only after they reach the market; supplements cannot claim to diagnose, treat, cure or prevent disease. It advises telling every provider about all supplements, including before surgery. Last updated January 2019.
