Biotin vs. Collagen: Which is better for players?

The NFL announced a rule change Tuesday that will make it mandatory for players to use a synthetic compound to help absorb the toxins in the game.

The new rule also means that if a player misses a practice, game or preseason game, he must either use an artificial supplement or wear a mask.

“I think this is really important for our players,” NFL Vice President of Football Operations Troy Vincent said in a statement.

“Players, coaches, and staffs need to be educated on the use of artificial supplements and make sure they’re wearing the right type of protective equipment.”

The league will also increase the amount of time a player must take an artificial compound and will require coaches to monitor players’ use of it during practice.
