Our Standards

How We Review Products

What we look at when we research a supplement or health product, and what our reviews do and don’t include.

What our reviews are

Our product reviews are research-based evaluations. We gather publicly available information about a product, compare the manufacturer’s claims with independent evidence about its ingredients, and explain what a consumer may want to consider before buying.

What our reviews are not

  • Not lab testing. We don’t laboratory-test products.
  • Not hands-on testing, unless we say so. Unless a review explicitly states that we purchased and used a product, you should assume we have not.
  • Not medical review. Our reviews are not currently reviewed by doctors or other licensed health professionals.
  • Not star ratings. We don’t currently publish star ratings or scores, because a single number can hide important nuance.

What we examine

  • Product details: what the product is, its form (capsule, powder, liquid) and its intended use
  • Ingredients and doses: the full ingredient list and amounts, and whether any “proprietary blends” hide individual doses
  • Available evidence: what independent research says about the key ingredients, at the doses studied, labeled as established, emerging or limited
  • Manufacturer claims: what the company says, and which claims are or aren’t supported by independent evidence
  • Safety information: known side effects, who should avoid the product, and possible interactions with medications, based on reputable sources
  • Manufacturer transparency: whether the company provides clear labeling, contact details and product information
  • Pricing: the price at the time of research, which can change
  • Refund policy: the terms, where we can verify them from the official source
  • Customer experience: only when it comes from a legitimate, identifiable source, which we’ll name
  • Limitations: what the product can’t do, and when a healthcare provider is the better first step

How we label information

In every review we try to make clear which information is verified (confirmed from an official or independent source), which is a manufacturer or vendor claim, and which is our editorial explanation.

Affiliate links in reviews

Many reviews include affiliate links, usually to the product’s official website. We may earn a commission if you buy through them, at no extra cost to you. Commissions don’t change what we report about the evidence, and we don’t use fake urgency, fake discounts or invented testimonials. See our Affiliate Disclosure.

Keeping reviews current

Formulas, prices and policies change. Each review shows the date it was last updated. If you notice outdated information, email contact@yoursupplementdigest.com. Read more in our Editorial Policy.

Talk to a professional

A review can help you ask better questions, but it can’t tell you whether a product is right for you. Check with your doctor or pharmacist before starting a supplement, especially if you’re pregnant, nursing, have a medical condition or take medication. See our Medical Disclaimer.
