I’m an aging athlete (almost 70) and I do a nine and a half hour full-body weight lifting routine over a three day period. Bottom line is, if it weren’t for Marine Phytoplankton I couldn’t do it. Not only does it boost my strength and energy levels, but my overall health and wellbeing are enhanced as well. I live in the United States so it takes about eight to ten working days for it to get here, but Dino always ships promptly so I know I can depend on consistent travel time and order accordingly. This is the best quality of all the Marine Phytoplankton brands I’ve tried and amazingly the best priced also.
