Frequently Asked Questions
Can I get enough antioxidants from food?
A diet rich in colorful fruits and vegetables provides many antioxidants. However, supplements can provide concentrated forms and specific compounds like glutathione that are hard to get from food alone.
What's the most powerful antioxidant?
Glutathione is often called the 'master antioxidant' because it recycles other antioxidants and is involved in numerous cellular processes. Astaxanthin is also extremely potent—up to 6000x stronger than vitamin C.
Can you take too many antioxidants?
Yes, extremely high doses of some antioxidants may interfere with normal cellular signaling. Balance is key—moderate supplementation combined with a healthy diet is the best approach.
