Do I need to refrigerate this in the summer? Located in LA and it gets hot.

I live in Central Texas and I do not refrigerate this product. Outside it is 103 degrees midday, but I keep my place at 78 degrees indoors daytime and the product works well. I love this and have been using it for three years now. It has been a game changer for me.
