How To Use
Our 1 month supply contains 60 capsules.
We recommend taking 1-2 capsules a day, with food. If you're new to magnesium supplements, we recommend starting with 1 capsule to build tolerance before increasing to 2, as the supplement’s potency is often best introduced gradually.
Always store at room temperature and keep away from direct sunlight.

Magnesium is the small, but mighty mineral powering over 300 of your body’s biochemical reactions. So remember, a lot of its transformative effects take place below the surface.
But most NothingFishy customers tend to feel the difference in 1-2 months. Of course, each of us is unique—so this timeframe is based on averages and will vary from person to person.
The shell is made from pullulan and maize starch, which are both plant-based ingredients.
