Try eating a mineral rich diet. Soups made from bone broth, lots of veggies, mineral water and low sugar smoothies if you don't have any sugar imbalances. Almonds, hemp protein powder are high in magnesium. Toss all that into the blender with some vegetables and a small quantity of fruit. There are plenty of recipes online. Give yourself a few weeks and see if you can tell a difference in how you feel. Maybe ask your Gastro about some of this stuff and see if they can give you a meal plan or refer you to a nutritionist.

Just be mindful of too much sugar. Sugar causes us to lose magnesium.
