Why This Vitamin C Formula is Gentle on Your System

If you've ever dealt with that annoying stomach discomfort from regular vitamin C, Ester-C might be your new best friend. Unlike standard ascorbic acid, Ester-C is a buffered, neutral-pH form that's kind to your digestive system. The patented production process creates vitamin C metabolites that your white blood cells can easily absorb and hold onto, giving you immune support that lasts all day. Plus, the addition of citrus bioflavonoids – those natural plant compounds from citrus fruits – gives an extra antioxidant boost to your body's defence.

So, What Exactly is Ester-C?

Ester-C 500 with Citrus Bioflavonoids is a unique, patented formula that combines calcium ascorbate with key metabolites to deliver vitamin C in a non-acidic way. Each tablet gives you 500 mg of vitamin C along with a citrus bioflavonoid complex, which may help with absorption and antioxidant activity. It's 100% vegetarian and free from common allergens, making it a handy addition to your daily wellbeing routine.

What Are the Main Benefits?

Ester-C provides 24-hour immune support, thanks to its clever formulation that keeps the nutrient available in your system. The citrus bioflavonoids help support your body's natural antioxidant defence. Vitamin C is an essential nutrient that helps keep your immune system running smoothly, supports collagen production for healthy skin and connective tissue, and helps reduce tiredness and fatigue. Because it's non-acidic, it's a top choice for anyone who gets tummy troubles from standard vitamin C.

Adding Ester-C to Your Daily Routine

As a dietary supplement, adults should take one tablet daily with food for best absorption. The 500 mg dosage is perfect for general wellbeing, and you can take it any time of day – many people find it easiest to pop with breakfast. Each bottle gives you a one-month supply (usually 30 tablets). As with any supplement, it's a good idea to chat with your healthcare professional before starting, especially if you're pregnant, nursing, or have a medical condition.
