@roblem I have been on a form of Beta Glucan for 13 years that was started at the immune therapy clinic I attend in the Bahamas. I have changed brands but now take Glucan Elite which I get on Amazon. I take a probiotic daily, Manuka Honey, and a medicinal mushroom mix powder from Real Mushrooms. Vegetables, nuts, and fruits are a bigger part of my diet now and sugar is kept to a minimum. The clinic I use in Bahamas has changed to Quantum Immunotherapy (Quantumimmunotherapy.net) and I started there right after my chemo/radiation in 2012. It was called the IAT Clinic (Immune Augmentation Therapy) then and has been active since the 70s. While the original doctors have passed away, the process still continues under Dr Brown and I give myself multiple injections daily. You can send me a private message or check their website for more information.
