Trial Summary

Do I need to stop taking my current medications for the trial?

The trial protocol does not specify if you need to stop taking your current medications, but it does require a 'washout period' of at least five weeks without vitamin supplements before enrolling. It's best to discuss your specific medications with the trial organizers.

What data supports the effectiveness of the treatment Fish Oil for reducing oxidative stress?

Research suggests that omega-3 fatty acids, found in fish oil, can increase the body's antioxidant capacity and reduce markers of oxidative stress, which are linked to inflammation and chronic diseases.12345

Is fish oil safe for human consumption?

Fish oil is generally considered safe for human consumption, but some fish oils may contain oxidized products that could reduce their health benefits. Studies suggest that omega-3 fatty acids in fish oil can improve antioxidant levels in the body, but the freshness and oxidation levels of the supplements can vary, potentially affecting safety.12467

How does the treatment Fish Oil differ from other treatments for oxidative stress?

Fish Oil is unique because it contains omega-3 fatty acids, which are prone to oxidation, potentially affecting their health benefits. Unlike other treatments, Fish Oil may require additional vitamin E to counteract increased oxidative stress, especially in older individuals.6891011

What is the purpose of this trial?

The American Heart Association and the American College of Cardiology (AHA/ACC) recently encouraged "increased consumption of omega-3 fatty acids in the form of fish or capsule form (1 g/day) for risk reduction" and stated that "for treatment of elevated triglycerides, higher doses are usually necessary for risk reduction" (Smith SC et al. Circulation 2006;113:2363-72). These recommendations are based on conflicting evidence about the efficacy of the omega-3 treatment with data derived from single randomized trials or non-randomized studies (Smith SC et al. Circulation 2006;113:2363-72). Much effort has been undertaken to elucidate the role of omega-3 fatty acids in the development of cardiovascular disease, but even recent meta-analyses deliver no clear picture; they either favor (Mozaffarian D Jama 2006;296:1885-99) or reject (Hooper L Bmj 2006;332:752-60) the hypothesis of cardioprotective effects of omega-3 FAs.The objective of the clinical study is to study the effects of fish oil on blood and urinary markers of inflammation and cell stress. By using different permutations of high-dose supplementation of omega-3 and omega-6 fatty acids versus different alimentary omega-3 fish doses and grain alcohol versus different kinds of red wine, this trial will study how omega-3 fatty acids, ethanol and red wine constituents modulate biomarkers of inflammation and cell stress.
