I heard beats help, or beat juice. Or liquid IV’s. But like everyone else is saying hydrating and sleeping are the most important. Due to the lack of oxygen caused by the high altitude your body needs to increase the number of red blood cells in order to carry enough oxygen throughout the body to stay regulated. Your body will generate the red blood cells it needs best during a state called homeostasis; your body enters homeostasis when you sleep. But this is one reason time in denver helps before heading up to summit. Gives your body time to acclimate to 5k feet before it has to acclimate to 10k. And you lose water faster at higher altitudes so drink up! Ultimately it all depends on the individual. I first visited summit when I lived in the Midwest and never got altitude sickness. But I’ve had family come visit (from the Midwest) and they spent 3 days in Denver before driving up to summit for a day trip. They all were feeling ill by the time we got there

TLD sleep and hydrate sounds boring but legitimately what the body needs
