Muscle and bone are worth protecting, especially after 40. This protocol brings together three key nutrients for it: creatine for muscle and mind, magnesium for calm and sleep, and vitamin D3 with K2 to help put calcium where it belongs.*

Magnesium lasts 30 days, creatine 50 and D3 + K2 60. Refill each one when it runs out; orders of $50 or more ship free.

Your ritual

For strong days, every decade

  1. Stir one scoop of creatine into your morning water, juice or coffee.
  2. Take one D3 + K2 capsule with breakfast, a meal with some fat.
  3. In the evening, take three magnesium capsules and put the phone face down.

Strong is a habit you keep, every decade.

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. Any time of day

    Creatine Monohydrate

    1 scoop daily, in water or coffee.

  2. Evening

    Magnesium Glycinate

    3 capsules in the evening.

  3. With breakfast

    Vitamin D3 + K2

    1 capsule daily with breakfast, a meal with some fat.

Why they work together

Creatine paired with strength training helps build and keep muscle, and a 2026 review of trials in women after menopause found more lean mass and leg strength with creatine and training than training alone, with growing research on the brain.* Magnesium is a mineral many adults fall short on. D3 and K2 work as a pair: D3 helps you absorb calcium, K2 helps direct it to bone.*

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.
