Its been a problem for most of my life.
Currently the supplements im taking are...
l-glutamine + fizzy vit c in morning
Vitamin D 7500iu in morning
Cod Liver Oil
Krill Oil 2g per day
ZMA at night before bed 4-5 times per week.
Niacin 500mg , few times a week, randomly
I started taking Inositol today aswell, will see how it goes.
I suspect it is the Vitamin D, since I only started taking large doses of it again recently and spending more time in the summer sun. Theres also a small chance it could be the krill oil, as I added it back to my supplement list at the same time as the D3.
