I have tried several magnesium sprays over the years, and due to sensitivity, many have made my skin itch. Ancient Minerals has the purest products I've found, and their magnesium oil is a favourite. Rubbing a few sprays into my feet or on my stomach before bed is brilliant as a sleep aid and evening self-care ritual.
My digestive system was a mess when I was stuck in hypervigilance, so magnesium tablets did more damage than good. Besides bedtime, I kept this oil on hand for whenever my body was tense or I was overstimulated. Massaging it into your skin is a great way to bring you back to the present and ground yourself.
