High‑Dose Antioxidants May Undermine Exercise Gains in Older Adults
A recent review reports that taking supraphysiologic doses of vitamin C and E together with collagen suppresses muscle growth, bone density improvements, and neuroprotective adaptations from exercise in older adults. In randomized trials, participants on high‑dose antioxidants gained only 1.4% lean mass compared with 3.9% in placebo groups. Moderate antioxidant intake, however, appears to support structural health.

If you're chronically inflamed, look at the fats you're eating. Seed oils flood your body with omega-6 linoleic acid. Your cells turn that into arachidonic acid. Arachidonic acid drives inflammation. I have seen thousands of people remove seed oils and watch their CRP drop, their joint pain improve, their skin clear up, and their energy come back. Your mitochondria do not run well on rancid polyunsaturated fats. They run on stable fats: grass-fed butter, ghee, MCT oil, and small amounts of extra virgin olive oil. Stop waiting for permission. Eliminate seed oils for 30 days. Test your inflammatory markers before and after. Track how you feel. Then decide what the data means for your body.
