A closer look.

Who we are

NutraRadar is an independently operated supplement label-comparison project. NutraRadar is the public editorial identity and contact point for this edition. We make supplement labels easier to compare through ingredient summaries, serving-size information and links to original sources.

Our first collection focuses on magnesium and creatine, with practical guides to reading labels and understanding certification. NutraRadar is at an early stage; we do not claim established readership figures or years of product-testing experience.

Editorial responsibility

Content is published under NutraRadar. Individual contributors are not publicly identified in this early edition. A NutraRadar byline identifies the publisher; it is not a claim of clinical qualifications or independent expert review.

There is no medical review board or product-testing team represented by this website. The guides explain published labels and source material. If a question requires personal health advice, a label comparison cannot answer it.

AI-assisted tools are used for website development and editorial drafting. Generated text is not a source. The source links and the limits of each record matter more than how confidently a sentence is written. This edition does not claim an independently audited human fact-checking process.

How we compare

We compare what the label says: ingredient form, declared amount, serving size and pack contents. Product information is linked to its manufacturer or retailer source, and the comparison displays when those sources were checked.

The initial products illustrate differences in form, amount and serving size. They are not ranked recommendations, a complete market survey or a list of the “best” supplements. Different national versions and pack sizes may use different labels.

Use the iHerb link beside each product to check its current price and availability. NutraRadar does not display live store prices. The retailer confirms the price, currency, taxes, shipping and available product version for your location. Compare ingredient amounts and serving sizes alongside price.

A labelled serving is the unit used to describe a product, not an instruction about how much you should take. Always check the current label on the exact product you are considering.

Product selection: a small, defined collection

This edition contains three magnesium and two creatine product variants using U.S. label information. The existing collection illustrates differences in ingredient form, serving size and pack size. It is a convenience sample, not a representative market study.

To add a record, we require an identifiable product and market, a specific pack size, a source showing its declared amount and serving unit, and a way to trace those fields. If an amount or variant is ambiguous, it must be marked unknown and excluded from calculations until resolved. Products are not included in a best-to-worst ranking.

Current links use one retailer, iHerb. That limits retailer coverage and does not demonstrate the lowest market price. Commercial availability is not evidence of product quality.

Use the right source for the question

• Product identity and declared contents: the manufacturer’s label for the exact variant. This is a manufacturer claim, not a laboratory result.
• Price and stock: the retailer for the selected country and currency. Calculators use prices you enter, not a live price feed.
• Certification: the certifier’s record for the exact product and scope. No certification is inferred from a brand name or pack photograph.
• Health and ingredient context: clearly linked original research or authoritative evidence summaries. Ingredient research does not prove the performance of a finished product.

A new page or design release does not renew the date on a product source check. Existing product records retain their 9 September 2026 date until their sources are checked again.

Sources, scope and corrections

Our educational guides link to sources such as the U.S. National Institutes of Health and NSF. Product labels describe the product; they do not establish whether someone needs it or what results they will experience.

NutraRadar has not conducted hands-on testing, laboratory testing or medical review of these products. We do not provide personalised medical advice. For questions about suitability, interactions or use, consult a qualified health professional.

Our correction procedure is to check the exact variant against the original source, correct the affected fields and calculations, and record the change and its date on the product page. This procedure is not a guarantee that every current record is error-free. Include the page URL and the relevant source when reporting a correction.

Affiliate & commercial disclosure

NutraRadar currently has no active affiliate partnerships, paid placements or affiliate tracking links. Product sources and retailer links are ordinary external links, and NutraRadar does not earn a commission from them.

We intend to apply to affiliate programmes. If approved, relevant links and commercial relationships will be clearly identified where readers encounter them. Affiliate relationships will not be presented as product testing or scientific endorsement.

Retailer availability is not an endorsement. Purchases, delivery, returns and customer service are handled by the retailer under its own terms.

About our images

Product pack images are sourced from the manufacturers linked in each product’s details. They help identify the selected pack; packaging can change and a photograph does not establish product quality or effectiveness. Pack images identify the selected variant and are not evidence of independent product testing.

Lifestyle images marked “AI illustration” show fictional people. They are not customers, health professionals, testimonials or evidence of product results. The unbranded still-life image is also AI-generated.
