What Does NOW Foods C-500 Do?
• 500 mg calcium ascorbate provides adequate dose with good tolerability.
• Only 10 mg citrus bioflavonoid complex may be underdosed for meaningful synergy.
• Includes 55 mg calcium but no clear evidence this enhances vitamin C absorption.
Is calcium ascorbate gentler on the stomach than regular ascorbic acid?
How much citrus bioflavonoid complex is actually needed for synergy with vitamin C?
Can I take one capsule daily year-round or should I cycle this supplement?
