Independent reviews. No brand deals.

Every product review follows the same process. We purchase products at full retail price. We never accept free samples, sponsored placements, or pre-release access from brands. If we review it, we bought it.

Our review process has three phases. First, we analyze the ingredient list against published clinical research. We look at specific strains, dosages, and whether the amounts used match what was tested in clinical trials. Second, we test the product ourselves over a minimum of 30 days. Third, we survey existing customer feedback across multiple platforms to identify consistent patterns.

We rate every product on five dimensions: ingredient quality, clinical evidence, real-world efficacy, value for money, and customer experience. Each category receives a score from 1 to 10, and the weighted average produces our overall rating.

We cite primary sources whenever possible. That means linking directly to published research on PubMed, clinical trial registries, and peer-reviewed journals. We avoid citing manufacturer claims as evidence.

Our editorial team includes contributors with backgrounds in nutrition science, clinical research, and consumer health journalism. Every article is reviewed for factual accuracy before publication.

We update our reviews when new evidence emerges or when companies change their formulations. Updated reviews are clearly marked with the revision date.

Top Health Insider may earn a commission when you purchase through links on our site. This never influences our ratings or recommendations. Products that score poorly are published with the same affiliate links as products that score well.

We believe transparency builds trust. Our revenue model is simple: we recommend products we genuinely believe are worth trying, and we earn a small percentage if you decide to purchase. You never pay more by using our links.
