Your ritual

For steady days, start to finish

  1. Take two Ashwagandha Plus with breakfast, before you open the calendar.
  2. Stir one scoop of creatine into water or coffee.
  3. Before bed, take three magnesium capsules and set the day down.

However full the week, the routine stays the same.

Each product's grade and its key study are below.

Your day, in 3 steps

Each product has its own time of day, so you always know what to take and when.

  1. Morning

    Ashwagandha Plus

    2 capsules with breakfast.

  2. Any time of day

    Creatine Monohydrate

    1 scoop daily.

  3. Evening

    Magnesium Glycinate

    3 capsules in the evening.

Why they work together

KSM-66® supports a healthy stress response, and in an 8-week placebo-controlled trial, men who took it with strength training gained more strength and muscle size.* The International Society of Sports Nutrition calls creatine the most effective nutritional supplement for high-intensity exercise and lean mass during training, with newer research on memory.* Magnesium glycinate is gentle on the stomach and supports relaxation and sleep.*

What the evidence says, plainly

Each product has its own grade for how strong the human evidence is today, so you can see the weight behind every claim.
