Bestselling author, podcaster, and lifestyle guru Tim Ferriss believes in the power of routine and consistency—and a trusted part of his daily routine is this Performance Stack.

Everything at a Glance

Gluten Free

Protein:

  • Promotes lean muscle mass and muscle growth
  • Supports recovery when taken post-exercise
  • Low calorie way to get protein into your diet

Creatine:

  • Helps regenerate adenosine triphosphate (ATP), which is the main source of energy for muscle and brain cells
  • May help support focus and cognition by increasing energy availability to your brain
  • Increases the energy available to muscles during training, resulting in being able to train harder
  • Helps develop lean muscle mass

Magnesium L-Threonate:

  • Enhances the quality of sleep and produces a calming effect
  • Helps support cognitive function, including memory, learning, attention, and focus
  • Helps increase magnesium levels in the brain, which may promote cognitive performance and overall brain health
  • Protein is a foundational macro that we actually need more of as we age due to increased muscle mass degeneration. It supports muscle performance, growth, and immune function.
  • Creatine is the main source of energy for your body—it can be used by your muscles or your brain, contributing to improved physical endurance and cognitive performance over time.
  • Magnesium L-Threonate helps to facilitate muscle contraction, regulate blood pressure, and synthesize DNA and proteins. It can penetrate the blood-brain barrier at higher levels than other forms of magnesium, which makes it the most bioavailable magnesium for the brain. It aids in the transmission of nerve signals, regulates neurotransmitter levels, and fuels energy production in brain cells. It also supports enzyme reactions, nerve health, protein synthesis, and muscle function.

Protein: Mix 1 scoop with 12 fl oz of your preferred liquid daily

Creatine: Mix 1 scoop with 6-8 fl oz of your preferred liquid daily

Magnesium L-Threonate: Take 3 capsules 30-60 minutes before sleep

  • Grass Fed Whey Protein Isolate:
    Chocolate: Grass-fed Whey Protein Isolate, ProHydrolase®, Natural Flavors, Cocoa, Salt Monk Fruit Extract, Stevia
    Vanilla: Grass-fed Whey Protein Isolate, ProHydrolase®, Natural Flavors, Salt, Monk Fruit Extract, Stevia
    Unflavored: Grass-fed Whey Protein Isolate, ProHydrolase®

    Our formula includes Grass-Fed Whey Protein Isolate, the highest quality protein powder available. Whey Isolate is easily absorbed with less lactose and more protein per volume than cheaper Whey Concentrate. With more protein for less calories, it’s the most efficient way to support muscle growth and recovery while delivering clean nutrition. We’ve also added ProHydrolase®, an enzyme that improves protein digestion and absorption for maximum benefit.
  • Creatine:
    Creapure® Creatine Monohydrate

    Momentous Creatine is sourced from Creapure®, the purest form of creatine monohydrate available and widely considered to be the gold standard of creatine. While the majority of creatine on the market is sourced from China, ours is a single-sourced ingredient from Germany with no additives, sweeteners, or other ingredients.
  • Magnesium L Threonate:
    Magnesium 145mg (from 2g Magtein® Magnesium L-Threonate)
    Other Ingredients: Rice Flour, Hypromellose (Capsule), Magnesium Stearate, and Silica

    Excellent supplement

    I use the magnesium L-threonate regularly every night (3 capsules). I track my sleep on my oura ring and garmin watch. These trackers do show consistent deep sleep and quantity of deep sleep has shown an improvement since I started using Mag L-threonate
