WHAT IS THE DIFFERENCE BETWEEN WHEY AND CASEIN ?
Both whey and casein are highly nutritious proteins derived from milk. Whey proteins have a thin consistency and are rapidly digested and absorbed, which makes whey beneficial around workouts. Casein proteins are thicker and take longer to be broken down. Casein tends to be more filling than whey and is commonly used at night or between meals.
WHEN ARE THE BEST TIMES TO USE R1 CASEIN ?
A slower digesting protein R1 Casein works well between meals and at bedtime when more sustained amino acid delivery is desired.
IS R1 CASEIN A GOOD SUBSTITUTE FOR R1 PROTEIN OR R1 WHEY BLEND ?
R1 Casein works best in conjunction with a fast acting source like R1 Protein or R1 Whey Blend. Use R1 Protein or R1 Blend during the day and take R1 Casein before going to bed to help feed your muscles while you sleep.
