Loved the Red Light Therapy book (used Audible) by Mark Sloan! I have been using light therapy for several years and wanted more in depth info, which he provided in the book. Have confidence in his research!
Also loved his Methylene Blue book (Audible) as well. I’ve been taking M-Blue for 1/2 yr but needed more info, which I received in his book.
Trust his research more than the medical profession!
