This combo is common because both sit under the “antioxidant” umbrella. In appropriate doses, most healthy adults can take them together. However, “more antioxidants = better” is not a safe assumption.\n\nKey considerations:\n- GI tolerance: high-dose vitamin C can cause heartburn/diarrhea; resveratrol may also trigger GI upset. Taking with food and starting low helps.\n- Product form: buffered vitamin C may be easier to tolerate; standardized trans-resveratrol matters.\n- Training adaptation: very high antioxidant doses are debated in endurance/strength adaptation contexts.\n- Medications: with blood thinners, cancer therapies, or chronic drugs, consult a professional.\n\nBottom line: generally compatible, but build a goal-driven, tolerable plan rather than “antioxidant loading.”
