@smartbaum sums it all up pretty well. Methylation is a poorly understood process and it seems that alternative health practitioners are just now jumping on the bandwagon seemingly without understanding the underlying science - just as our fellow anon has stated. Supplements alone cannot fix some of these underlying problems with mitochondrial dysfunction. Once again, light and other frequencies can have healthful or deleterious effects on how the body functions. It is hard to make money on sunlight. Thanks
