Quick Facts

Who SISU Ester-C 600 Is For

• Anyone who wants daily vitamin C for immune support and good health
• People who find regular ascorbic acid too acidic or hard on the stomach
• Those supporting collagen formation and healthy skin, bones, cartilage, gums and teeth
• People under physical or mental stress, and older adults — groups SISU notes may have lower vitamin C levels
• Vegans who want a clean, plant-based capsule

Who this product is NOT for:

• People who prefer a chewable — SISU Ester-C 500 mg Chewable comes in flavoured tablets
• Anyone limiting calcium on medical advice — each capsule adds 72 mg of calcium
• People with a citrus allergy — it contains bioflavonoids from lemon, grapefruit, orange and mandarin orange

Vitamart's Take

Ester-C 600 is one of the most popular ways to take vitamin C for a reason: you get a solid 600 mg dose in a buffered form that's gentle on the stomach, and SISU adds 100 mg of citrus bioflavonoids. Ester-C's big talking point is staying power — clinical studies show it raises vitamin C levels in the body for up to 24 hours. One capsule a day covers most people, two when you want more support. The 240-capsule size is great value for families or long-term users.

How SISU Ester-C 600 Compares

Ester-C vs. regular ascorbic acid

Plain ascorbic acid is acidic and can upset sensitive stomachs. Ester-C is buffered with calcium, making it less acidic, and contains vitamin C metabolites such as L-threonate.

Ester-C 600 vs. Ester-C Supreme

SISU Ester-C Supreme also provides 600 mg of buffered calcium ascorbate but adds quercetin. Choose Ester-C 600 if you just want vitamin C with citrus bioflavonoids.

Capsules vs. 1,000 mg tablets

SISU Ester-C 1000 mg Tablets give a higher dose with bioflavonoids, acerola, rose hip and rutin. The 600 mg capsules are smaller and let you choose 1 or 2 a day.

What Is Ester-C?

• Ester-C is a patented form of calcium ascorbate, made by buffering ascorbic acid (regular vitamin C) with calcium in a water-based process
• It is less acidic and easier on the stomach than ascorbic acid

• Clinical studies show that Ester-C increases vitamin C levels in the body for up to 24 hours
• Humans cannot make vitamin C, and it is easily destroyed by heat, cooking and storage — so a daily intake matters
