Our son's wedding venue was a 8,200 feet elevation. We got a variety pack of BOOST to make available to our myriad guests coming up from sea level. Among those that expressed gratitude for the extra help included 70-somethings struggling with cardio-vascular system limitations, desk-denizens that wanted to test out some of the mountain trails and young, healthy, but very pregnant young women who were carrying and breathing for two. It was an appreciated addition that made our guests enjoy the event to its fullest. Thanks, BOOST!

Very quick shipping!

great.

THis works for me during allergy or fire season or after a long hike!

I bought this to help with shortness of breath after physical exertion. It seems to shorten the period of time that it takes to catch my breath and be able to continue on.
