ADVICE

Add One Scoop Of Collagen To Your Coffee

  • Try adding one scoop of collagen powder to your morning coffee to boost collagen intake easily.
  • Dr. Eric Berg recommends this daily habit because one scoop supplies glycine and dissolves with no taste, often with a bit of cream.

Dietary Protein Lacks Collagen Compared To Body Needs

  • About 30% of the body's protein is collagen, yet typical dietary protein contains only 1–3% collagen.
  • Modern preferences for tender muscle meat and avoiding nose-to-tail eating create a large collagen intake gap.
