Can Lipoflavonoid Cause Leg Cramps?

Can Lipo Flavinoid cause leg cramps? Started taking L-F for tinnitus a few days ago and it is too soon to tell if it works, but, I am experiencing leg cramps. I am 75 and Walk/jog about an hour or more every day in the morning and it is becoming an issue.
I take "I-Caps" as recommended by my eye doctor and wonder if there is too much of a vitamin load.
