Are there any side effects of antioxidant supplements?
Most antioxidant supplements are safe when taken as directed. However, high doses of certain antioxidants can potentially cause side effects. It's always advisable to consult with a healthcare provider before starting any new supplement regimen.
How do I know if a supplement is high quality?
Look for certifications from reputable third-party testing organizations like USP, NSF, or ConsumerLab. These certifications indicate that the product has been verified for its ingredients, potency, and purity.
