White Plains, New York, March 27, 2018 — Bone broth is promoted as a natural source of collagen, an immune-booster, and a remedy for everything from joint pain to wrinkles. But how much collagen and protein is really in popular bone broths? Are bone broth labels accurate? And is there evidence that bone broth really works?

To find out, recently tested popular bone broth liquids and powders sold in the U.S., checking to see how much collagen and total protein they contained. ConsumerLab also tested each bone broth to see how much sodium it contained and whether it was contaminated with heavy metals (lead, cadmium and arsenic). Products were also compared on cost and taste.

The tests revealed that one bone broth shockingly contained 62% less protein and 75% more sodium than listed on its label. found the amount of collagen in a cup of broth to range from 2.5 grams to 8 grams across the products; total protein ranged from 3.8 grams to 13.3 grams; and sodium ranged from 95 mg to 503 mg. The cost to obtain an equivalent amount of collagen from the products ranged from just 61 cents to $9.99.

Among the bone broths that passed tests of quality, provided good amounts of collagen and protein, and were well priced, identified its Top Picks.
