R1 Source7 Protein: Staged-Release Protein for All-Day Muscle Support

R1 Source7 Protein is a premium, multi-source protein blend designed to deliver a steady flow of amino acids to your muscles over an extended period. Using seven distinct protein sources, ranging from fast-digesting whey isolates to slow-releasing casein, this formula provides balanced nourishment ideal for morning, midday, post-workout, or nighttime use.

Each scoop contains 22 grams of high-quality protein with naturally occurring EAAs, BCAAs, and other essential amino acids needed for recovery, strength, and lean muscle maintenance.

What Makes Source7 Protein Different?

Most protein shakes focus on a single protein type, which limits absorption time and amino acid delivery. R1 Source7 Protein uses a tiered absorption matrix, allowing your body to benefit from both rapid and extended protein release.

Key advantages include:

• 7 high-quality protein sources

• Fast, medium, and slow digestion speeds

• Over 10g essential amino acids (EAAs)

• Over 7g conditionally essential amino acids (CEAAs)

• Over 4g non-essential amino acids (NEAAs)

• More sustained amino acid delivery

• Smooth flavor and mixability

This versatility makes it an excellent all-in-one daily protein option.

The Seven Protein Sources Inside Source7

Source7 Protein blends fast-, medium-, and slow-digesting proteins to ensure a staggered release of amino acids over several hours.

Fast-Acting Proteins (Rapid Absorption)

Designed to begin supporting muscles almost immediately after consumption.

• Whey Protein Isolate – fast absorption, low fat & carbs

• Whey Protein Concentrate – naturally rich in bioactive compounds

• Hydrolyzed Whey Protein – pre-digested for ultra-rapid uptake

• Native Whey Protein Isolate – derived directly from milk for higher purity

Medium-Release Proteins (Balanced Digestion)

Great for steady amino acid delivery after the initial whey burst.

• Milk Protein Isolate – contains both whey and casein for balanced release

• Pea Protein – plant-based protein with a strong EAA profile

Slow-Release Protein (Extended Absorption)

Ideal for prolonged amino acid delivery and nighttime recovery.

• Micellar Casein – digests slowly, helping support muscles for hours

This combination ensures your muscles receive amino acids over multiple digestion windows, rather than all at once.

Why Staged-Release Protein Matters

Protein timing can greatly influence muscle recovery and growth. A staged-release formula like Source7 offers benefits such as:

• Improved muscle repair throughout the day

• Reduced muscle breakdown during downtime

• Better support for lean muscle maintenance

• Enhanced amino acid availability any time

This makes Source7 perfect for everyday use—not just post-workout.

Amino Acid Profile (Naturally Occurring)

Each serving provides:

• Over 10g EAAs – essential for muscle protein synthesis

• Over 7g CEAAs – including glutamine and arginine

• Over 4g NEAAs – supporting metabolism and tissue recovery

These numbers reflect naturally occurring amino acids found in quality milk-based and plant-based proteins.
