Altitude Boost. High Altitude Training in a Bottle to Increase VO2 Max, Endurance, Oxygen with Alpha Lipoic Acid, Iron and Vitamin B 12 (60 Tablets)

I can't say for sure if these were entirely beneficial for altitude because I live in Kansas. They're vitamins. They do provide a boost of energy but not like a pre-workout or energy drink or something like that. I mean, it's beneficial and works in that way. They're large sized, so a bit difficult to swallow.

Little harder to swallow that what I'm used to. I didn't get a chance to try activities at altitude, but at more normal altitude, it doesn't seem to greatly increase my stamina that could say for sure.

As a competitive athlete that lives at sea level, I am skeptical about Altitude Boost efficacy, but the ingredients listed do have cardiovascular and lung efficiency support. I have trained at high altitudes, and supplementing iron is something I would do. But at training at sea level, I typically wouldn't take extra iron unless the humidity is high over consecutive days. I do know that NAC helps with breathing and lung capacity. B vitamins provide energy support. I like the presumption of the product, and I look forward to testing it out. But knowing that you still have to do the "work" to gain any benefits and whether or not they are from the Altitude Boost supplements or just from aerobic improvement will be up to the user. I just don't put blind faith in supplements alone.

Overall Good Basic Supplement. Nothing super special to write home about. They seem to give a mild boost due to the vitamin mixture. I think it is worth adding to the regimen. Not exactly sure why they are marketed as "altitude," but whatever. as a long distance endurance runner, I am up to trying anything at the right price. These do what they do. I like them well enough to buy again.

Can't say I've noticed a difference in my athletic performance after taking this supplement compared to not taking it, but can't think of it being bad to take a little extra B vitamin and iron. Tablets are large as others noted, but can be swallowed.

Unfortunately I cannot state whether or not these worked for me since the bottle smelled like rotten eggs upon opening and I'm not comfortable taking them. It was properly secured with both an external and internal safety seal so they were not tampered with and the printed expiration date is still around 18 months in the future, but I do not want to take the risk of consuming these in case they are spoiled somehow (due to transportation conditions or something similar). Hopefully this is an isolated incident and the product works well for others.

To be honest these are not huge tablets, they would be equivalent to the size of jumbo capsules approximately just slightly bigger. To test these, I used exclusively for my pre-cardio prepation which includes caffeine. I live in the high desert region of California, the altitude here is 3,000 ft above sea level, so while I am already used to the elevation, climate and temperature changes by now, any extra boost is welcome to my cardio and exercise regimen. One thing I can say Ive noticed is less shortness of breath, which is what I normally have in 5 min interval jog training (treadmil, 5speed/3 elevation+). I run 30 minutes in a fasted state, I can tell what works and what is not adding. I would say for my case its working.

Altitude Boost is a game-changer! It mimics high-altitude training, enhancing my endurance and oxygen utilization. I've noticed significant gains in speed and recovery. However, I wish the tablet size was smaller for easier consumption. Perfect for athletes striving for peak performance!"
