When do you need antioxidants?For the most part, your body’s natural antioxidants can manage the detoxification of these free radicals. However, even when you’re trying to be your healthiest, you may face increased environmental factors and toxins that can combat the positive effects of your body’s natural antioxidants. An increase in damaging factors can occur through smoking, weight gain, pollution, stress, an unhealthy diet and even exercise; and this production of free radicals can become excessive, resulting in a need for additional antioxidants.
Which antioxidant is for me?Boosting your antioxidant intake can help provide added protection for your body. Nature provides us with a wide range of antioxidants, and because they are so varied, different antioxidants provide benefits to different parts of the body. For example, if you’re looking to keep your eye health in check, betacarotene (and other carotenoids) are beneficial. Lecithin phospholipids, found in astaxanthin which is sourced from the microalgae Haematococcus pluvalis, support the maintenance of healthy cell membrane function. Vitamin E is known to help support the cardiovascular system and cognitive health as well as provide antioxidant benefits, while trans-resveratrol, a red-wine antioxidant, also has heart benefits due to its ability to reduce oxidative stress. The antioxidant lycopene helps maintain prostate health, while flavonoids are especially beneficial for heart health. Proanthocyanidins - found in cranberries - are your go-to antioxidant for urinary tract health.
Glutathione is king of the antioxidantsGlutathione, known as the king of antioxidants, is the most abundant endogenous antioxidant that plays a pivotal role in regulating oxidative stress, detoxification and immune function. Produced by the body with precursors from the diet, glutathione is most concentrated in the liver, spleen, kidneys, intestines, lung fluid, lens, erythrocytes and leukocytes; the liver being the largest glutathione reservoir where it is involved in detoxification. Glutathione levels naturally decline with age, beginning to weaken around age 45 and declining quickly after 60 years. Intense physical exercise also reduces glutathione levels in blood, muscle and the liver. Oxidative stressors that can deplete glutathione include: ultraviolet and other radiation; viral infections; environmental toxins, household chemicals and heavy metals; surgery, inflammation, burns, septic shock; age; intense exercise; and dietary deficiencies of GSH precursors and enzyme cofactors. It seems that even when we are trying to live a healthy lifestyle, we may be in short supply of glutathione—and that means we’re missing a critical piece of the body’s natural defense mechanism. As glutathione levels may be difficult to increase through the diet alone, it is more important than ever to make this powerful antioxidant part of your daily health regimen. ‘Ask a Naturopath’ at Mr Vitamins about which Glutathione is right for you
