Health Insider is an independent health magazine for readers in the United States. We cover nutrition, sleep, heart health, fitness and everyday wellness in plain language, and when a product claim needs checking, we buy it at retail and test it against criteria we publish in advance. No sponsored rankings, no affiliate commissions.
Glycinate, citrate or oxide? We compared five bestsellers on absorption form, elemental dose, third-party testing and value.
EPA and DHA per softgel, triglyceride vs. ethyl ester form, freshness and purity testing: five popular fish oils side by side.
CFU count is only half the story. We looked at documented strains, delivery technology, storage and price per day.
Grams per scoop, sourcing, mixability and cost per serving: five collagen powders from the US bestseller lists.
Most of what we publish is editorial: explainers, guides and reporting on health and nutrition. When we compare products, we do not rely on manufacturer claims or sponsored reviews. We buy every product at retail, read the label the way a pharmacist would, and rate it on criteria we publish in advance.
Health Insider is an independent health magazine for readers in the United States. A small editorial team covers nutrition, sleep, heart health, fitness, mental well-being and the products that come with them. We write the way we would explain things to a family member: plainly, with the trade-offs on the table.
Independence. We take no payment for placement. Brands have no influence on which products we select, how we score them, or where they rank.
Transparency. Prices are approximate, scores are the editorial team's assessment. Product links go to Amazon.com and are not affiliate links. Found an error? Let us know and we will update the comparison.
