I set a goal to cycle 100 miles on my 55th birthday, something I have never done before. I made O2Boost part of my nutrition plan and on Tuesday, set out on my ride. Seven hours, eighteen minutes later and one flat tire, I successfully completed 101.5 miles. O2Boost will be part of my nutrition plan going forward. -Greg U, Maryland

O2Boost has been a game changer in my strength and cardio training. I've noticed that I can lift heavier and run longer/faster when I take it 30-45 minutes prior to working out. My Spartan Race times have improved and I don’t find myself with burning lungs or gasping for breath! -Morgan C, Florida

I was amazed at the amount of energy I had while hiking and that I didn't seem to get as winded. I was so surprised that I was able to easily hike up to an elevation of 7693' after living in Dallas, at an elevation of only 430'; experienced no altitude effects like headaches or the typical leg cramps. For recovery, I took a second capsule after the hike and wasn't sore at all the next day, another incredible
benefit." -Laura M, Arizona

Actually, I have to admit that I was skeptical. I took a capsule in the morning and didn't really feel differently, I'm not sure what I was expecting but I can honestly say I felt pretty normal and went about my day. The next weekend on my mountain bike ride I thought I'd try it this time while exercising. What a difference! I ended up finishing my ride with one of my fastest times, no lactic acid buildup or burning in my calf muscles, no cramping." -Dave H, Michigan

As an athlete, I am always looking for ways to improve my performance and gain an edge on the competition. During my 50K ultra trail race, I used O2Boost and noticed results almost immediately. My breathing was stronger, and the lactic acid build-up was significantly reduced. I was able to push myself harder than ever before, and as a result, I came in 7th place overall on my first ultra! It's no exaggeration to say that O2Boost was the key to my success. If you're looking for a way to take your training to the next level, I highly recommend giving O2Boost a try. -Ian B, California

I've been taking O2Boost now for about a year and truly love how it helps me with my breath work while doing my daily yoga routine. I feel more focused, balanced and energized. On really intense work out days, I'll take some O2Boost afterwards to avoid any muscle soreness. Last but not least, it's been a big help in adjusting to the mile high altitude here in Denver. Love it! -Michelle L, Colorado
