I am in my early 60's and have had some issues with leg, foot and hand cramping for a few years.

I started supplementing with 400 mg magnesium glycinate powder half and hour before bed time and my leg and foot cramps have resolved. I also find that I get to sleep much faster and rarely wake up during the night.

My hand cramping was also improved but would surface when I used my hands for extended periods. My fingers cramped after typing for extended periods. They would also lock when doing auto repair, lawn mower maintenance, or yard work. I also experienced some joint stiffness in one hand joint which may be the early onset of some arthritis.

I found some references to "magnesium oil lotion" and followed it up. There are many recipes online. Many include shea butter, coconut oil, water, and magnesium chloride. I was a bit skeptical about the effectiveness of transdermal absorption of magnesium.

I have been using it for about a year. I apply a generous amount to my hands, legs, arms, and upper torso in the morning. The results have been outstanding. I rarely get hand cramps and joint soreness is greatly improved. I keep a small container of the lotion with me at all times. Whenever I experience cramping or joint soreness an application usually does the trick.

One tip however, is not to apply to broken skin or freshly shaved areas. I applied "magnesium oil lotion" to my neck area after shaving. The "sting" is very uncomfortable for a few minutes.
