Jarrow Formulas

A single-nutrient and named-formula range across vitamins, gut health and collagen, mostly in vegetarian capsules and softgels.

Product naming is the useful signal in this range: items labelled "Sustain" are sustained-release tablets rather than standard capsules, and B-Right is the brand's B-complex, so a name tells you the format as well as the ingredient. Most products are one nutrient at one strength, which makes them easy to compare directly against the equivalent from another brand on the ingredients panel. Live culture products state their strains and counts, and some need refrigerating — the product page says which.
