Nature energy refers to the energy around us, whether that's sunlight, the heat in the earth, the potential energy of gravity, the wind, etc. I don't see why physical and mental energy then suddenly have to be magical in nature. Especially since it's explained that the chakra network gathers energy from every cell, while the Eight Gates network regulates this chakra which directly influences very real and very physical properties like strength. It essentially reverses the direction of normal chakra production: Rather than chakra stemming from the cells and granting external power, chakra can be cent to cells to improve their performance.

The supernatural part of chakra seems to stem from whatever Hagoromo did exactly.
