Frequently Asked Questions
It's the most abundant protein in your body, the scaffolding behind your joints, bones, and connective tissue. Marrow delivers it as hydrolyzed peptides your body absorbs easily.
Most people feel a difference in two to three months of daily use. Collagen rebuilds slowly, so the longer you take it, the more you get. Stopping early is the most common mistake.
It's one of the better-studied supplements for joints and bones. In a 24-week Penn State trial, active adults taking collagen reported less joint pain. It isn't a magic fix, it's a daily building block that works with consistent use, which is why we back it with a 90-day guarantee.
Most brands give 10 grams or less. Marrow gives a full 20 grams of one clean ingredient, no fillers cutting the dose.
Both. Your bones are about one-third collagen by weight. In a 12-month study, older adults taking collagen peptides daily increased their bone density while the placebo group did not.
One 20-gram scoop a day. It's unflavored and dissolves clear in anything, hot coffee, cold water, a smoothie.
One pure ingredient, collagen peptides from grass-fed, pasture-raised cattle. Third-party tested, made in a GMP-certified facility.
Then you pay nothing. Try it for 90 days. If you don't feel a difference, we refund you, no hassle.
