Oxidative Stress
A Powerful Carotenoid Called Astaxanthin Can Reduce Oxidative Stress And Boost Health
By Darrell Miller
So, what is astaxanthin anyway? Astaxanthin is a potent and powerful carotenoid, like beta carotene, that helps the body boost its immune system and fight off damage done by free radicals and oxidative stress.
The highest known levels of astaxanthin in nature are found in the algae Haematococcus pluvialis, which is a microalgae found in tropical locations. While in fact Haematococcus is a green algae, when astaxanthin is extracted, this molecule is what lends the trademark pink-orange color to salmon and certain crustaceans.
Like many other carotenoids, astaxanthin is a powerful antioxidant. Antioxidants assist our bodies to fight off free radicals and thwart the damage that is the result of oxidative stress. Oxidation in and of itself is a normal cellular process, and when our bodies are in balance and our immune systems are fully charged, it’s not a problem.
However, when our bodies cannot keep up with the number of free radicals we encounter oxidative stress occurs. Certain conditions of the body and numerous outside factors contribute to this level of susceptibility. Conditions such as diabetes increases a person
Where can I get Information on Oxidative stress in disease state?
I need some information on what oxidative stress is about an the diseases associated with this condition. Valuable web links and info will be highly appreciated
Would living at high altitude reduce oxidative stress on the body?
. . .considering the reduced pressure of air (and thus oxygen) at high altitudes.
My hunch is that in much the same way calorie restriction is thought to reduce oxidative stress, “oxygen restriction” may have the same effects.

No. The body responds by increasing the # of red blood cells and the amount of hemoglobin carried on the RBCs — to an extent.
Athletes frequently train at altitude so as to increase the oxygen carrying capacity of their blood. In preparation for the 1968 Olympics in Mexico City (altitude around 6000 feet), an Olympic training camp was established at Lake Tahoe (altitude around 5300 feet).
If that is true, then training on Mt. Everest would be the best! Nope! The oxygen molecules are so far apart at 29,000 feet that there is so little oxygen life cannot be sustained.
So, at REASONABLE altitudes (like Lake Tahoe), the amount of oxygen carried by the blood would increase and oxidative stress (free radicals) would remain.
No, “oxidative stress” is not a myth. People with chronic-degenerative diseases suffer a great deal from it. But healthy individuals will not oxidate because of exercise. The human body has resources to deal with this kind of “stress”.

d. Free radicals
Hello KitKat
Oxidative stress is when cells get damaged within your body – this is common and the main reason for ageing, you will notice a lot of anti – aging creams contain anti – oxidents for this reason. An example of oxidative stress is when you cut an apple and it turns brown quickly due to exposure to oxygen but if you apply lemon juice (Vit C – another anti – oxident) it won’t go brown.
So – Vit E will help your skin cells but won’t do much for actual stress, the B vitamins are much better for this.
Try not to get stressed at school, try to sort out the problems whatever they are, school should be the best years of your life – you’ll get so much more stress in the working world!
What’s antioxidant protection against oxidative stress?
Well my dad bought these capsules, and it says vitamin E : antioxidant protection against oxidative stress. He said it helps with stress or something because I have been really stressed about school and all that.
The question is, what will it do for me?
Will there be any side effects?
Should I take them? (I’m 13 )
Thanks
Why is execise good for you if it causes so much ‘free radical damage’ (oxidative stress) ?
When reading about execise – it keeps mentioning how it produces lots of bad free radicals and oxidative stress but when I actually do it – I feel great afterwards. Is this oxidative stress a myth?
