I wonder how this affects the thinking on the benefits of anti-oxidants present in foods such as blueberries, green tea etc

Vitamins in foods work differently than vitamin supplements. Always have, always will. We keep trying to concentrate the benefits of real food into a pill and it just doesnt work. Food has micronutrients and phytochemicals that work together with the digestion process. Supplements dont.

| I don't really buy what they are studying. I think if one is to take additonal antioxidants, balance is key. Why not study a formula with all these nutrients and some herbs combined. Not just some vitamins individually. My formulas I take have fat soluable, water soluable, food form and universal antioxidants. If you just take Vit. C or Vit. E, well I am not a fan of that. Take a formula that has multiple antioxidants and food form antioxidants from fruit and vegetable extraction. Many herbs also have a much more powerful antioxidant effect than C, E and beta cartotene. I take these antioxidant but with many others for synergy. And, BTW, eating blueberries, strawberries and other high antioxidant foods is ideal. Eat eat eat! My god don't let this study affect your eating of quality food. |

Actually, yeah...it's wel known andl documented that certain anti-oxidants are pro-oxidative in too high quantities.
That said, it's typically so easy to get extra antioxidants from foods, and sooo much cheaper than pills. At Kroger's, you can get 100 bags of organic green tea on sale for $5 every couple of months. Thats just one example. |

From what I've gathered on these forums, garlick is the way to go.   |

| I haven't really read the article but too much vitamins, especially the fat soluble ones can be harmful or even toxic in some cases, just like anything else. Plus our bodies have a better way of keeping a proper balance of vitamins if it is from food (in some cases). This is because some vitamins in food are in an inactive form and only get changed to an active form if the body decides to do so. It's possible multi vitamins are in active forms and in some cases the body will get too much of a good thing. This is just me throwing out some info. I don't know the exact chemical forms in the multivitamins (nor do I want to) or the way all of the vitamins are digested and absorbed. |

| I always assume it's better to get things from food because otherwise you just have expensive urine. |

I wish I'd been there to hear that as the line started forming in front of the finish line. No idea what I'd have done about it, but I wish I'd heard it in person instead of 3rd party. |

| You should only take vitamins if your trying to solve a problem, its been proven that taking vitamins or supplements won't enhance performance in a direct manner, but if you have a cold and vitamin C prevents it from getting worse, then in an indirect way, its helping you. My favorite drink is chamomile tea with a teaspoon of virgin coconut oil. |

Did you just make that up.. or did someone forget to tell the thousands of doctors and scientists who find the very opposite year after year?

Creatine increased my strength/power nearly 20%. I took it for 5 years while lifting. My bench press went from 250# to 310# in a fairly quick period of time. I hit the golf ball 20-30 yds further and hit 4-6 homeruns in softball each of those years. I went off creatine and have not hit a homerun  since nor do I hit the golf ball as far. And now I can bench about 240. BUT, while on creatine, I could not run without discomfort/achiness (because of extra weight) and my race times were much slower than now.
Also, I know I race better/faster with high doses of herbal caffeine in me before races. Can't tell you exactly how much better but I know it is better - probably 10-15 sec. in 5K and higher in longer races. |
