The liver is like a a washing machine which cleans away not only the products of metabolism but also food, drugs and other things we imbibe. Normally is is only ticking over, and is like a derated aero engine. If you damage or poison it, these markers will rise but it still works. If you poison or damage it further it can't cope and you get liver failure.
All you can say is that your liver has been unhappy, and I am afraid this site is unlikely to help you much more. You really need to go and see a liver specialist. It is quite possible you have had an infection or other illness, or you may have some inherent disease. Many are self limiting but rather than worry, go see a doctor. Clearly it isn't alcohol as you don't drink!
I wouldn't worry about fluctuating numbers as this is common and the tests are not that accurate. You clearly have an unhappy liver but the slight rise in one number may be irrelevant and your doctor will follow them over a longer period
However this does highlight the issue of self poisoning with over the counter supplements, vitamins, chemicals, food additives and the like. Unlike the drugs your doctor gives you these have often never been tested and the actual ingredients are unknown and of variable quality. It is a free world and you can take what you like but caveat emptor
