Antioxidants tested for heart attacks
Safety and Pharmacokinetics of a Combined Antioxidant Therapy against Myocardial Reperfusion Injury: A Phase 1 Randomized Clinical Trial in Healthy Humans.
Partial focus on vitamin C
In a recent clinical trial, we examined how a combination of antioxidants, including vitamin C, affects heart attack recovery. This study involved healthy participants who received either a blend of antioxidants or a placebo through an intravenous infusion. We measured the levels of vitamin C and other components in the blood, looking for signs of oxidative stress and monitoring any adverse effects.

Our findings showed that the antioxidant combination significantly increased vitamin concentrations compared to the placebo group. Moreover, we observed that this therapy seemed safe, with only mild, non-serious side effects reported in a small number of participants.

While antioxidants like vitamin C have been linked to health benefits, this study focused primarily on their safety and levels in the blood during a heart-related procedure. Although promising, we cannot definitively say that this approach improves outcomes for heart attack patients just yet. More research will be needed to explore its effectiveness further.

Heart health improvement
Linus Pauling may be right. I have gone through three 3-pound tubs, and it hasn’t harmed me; in fact, I could still eat and might be clearing my arteries! After three years, my nuclear stress test now shows normal results regarding my heart health.

Supports heart health
I find the Crystalline Vitamin C 227 g from Now Foods, a dietary supplement in powder form, is effective for boosting weak immunity. It helps maintain youthful skin and protects against heart attack, stroke, and cancer. This vegan product dissolves easily in water and has high pharmaceutical quality verified by GMP certification. One serving contains 1100 mg of vitamin C, which meets the daily requirement for adults, offering good results at a reasonable price.
