Okay, so (regarding Sardi) any actual pigment is the result of its accumulation over time (and lipo is not in itself a pigment, instead becomes one) due to imbalance between the rate in which it forms vs. the rate it is eliminated? (Fifth grade answer - form of a question.)
Site goes on (as you know) to state that the iron chelates Lipofuscin composites. And elsewhere I find that residue from lysosomes is what creates lipo in the body, in general. These lysosomes are both enzymatic and acidic. (weird)
I'm gonna' begin the guess quest (how do we get rid of it) by suggesting the answer involves (why not) some IP6, proper/adequate enzyme, electrolyte (and H20), sulfur intake (Dimethyl sulfoxide/Dimethylethanolamine), omegas (Docosahexaenoic acid, linolenics), chlorophyll (mag), lotsa O2, , rendering blood purity and photosynthetic enrichment - ultimately to reach full body Zeta potential, oxygenation, ionization.
And a few months of Orthiodosupplementation to speed up the removal (assist the above in removal of) metals, pathogens, and dislodge supplanted halogens (f,b,c) from toxic build up/poisoning.
Some CS to kill the ongoing and inevitable invasion of the germ and virus infested/infused world around us.
