How to compare SIGNILIFE products
Brands often sell the same collagen in several sizes, flavors and formats. To compare fairly, look at the grams of collagen per serving, the number of servings and the price per serving rather than the tub price. Check the collagen source (bovine, marine or multi-source) if you avoid certain foods or have allergies.
