Description

Ester-C Gold is Biogena's premium Vitamin C, built on the patented Ester-C® complex, a buffered, non-acidic form containing calcium L-ascorbate and the natural metabolite L-Threonate.

It's gentle on sensitive stomachs and stays active in white blood cells for up to 24 hours for all-day immune support.

It's enriched with elderflower extract, quercetin, and grape seed extract for added antioxidant power, and it supports collagen formation and protects cells from oxidative stress.

It's made in Austria by Biogena under its pure substance principle, with every batch independently tested.

This is a food supplement, not intended to diagnose, treat, cure, or prevent any disease. Consult a healthcare professional before use, especially if pregnant, nursing, or on medication.

How to use

Take 1 capsule daily with a meal and plenty of liquid, or as advised by a healthcare practitioner.

Because a solid daily starting point is often 500 mg of Vitamin C, roughly one capsule of Biogena Ester-C Gold, this dose can be adjusted upward for higher needs — for example during intense training, high stress periods, or increased environmental exposure — ideally under professional guidance.

Ingredients

Calcium L-ascorbate/L-threonate (Ester-C®), elderflower extract, quercetin, grape seed extract, hydroxypropylmethylcellulose (capsule shell), cellulose powder (bulking agent)

Frequently Asked Questions

What makes Ester-C Gold different from regular Vitamin C?

Ester-C Gold uses a patented, buffered form of Vitamin C — calcium L-ascorbate combined with L-threonate — rather than standard ascorbic acid. This makes it non-acidic and gentle on the stomach, while the L-threonate helps it stay active in immune cells for up to 24 hours.

Is Ester-C Gold suitable for people with sensitive stomachs?

Yes. Ester-C Gold is specifically formulated to be non-acidic and stomach-friendly, making it a good option for people who experience discomfort with regular, acidic forms of Vitamin C.

How do I take Ester-C Gold, and can I increase the dose?

The typical starting point is 1 capsule daily (500 mg Vitamin C) with a meal and plenty of liquid. During periods of higher demand — intense training, elevated stress, or increased environmental exposure — the dose can be adjusted upward, ideally with guidance from a healthcare professional.

What other ingredients are in Ester-C Gold besides Vitamin C?

Alongside its Ester-C® complex, Ester-C Gold includes elderflower extract, quercetin, and grape seed extract — natural bioflavonoid and antioxidant compounds that complement Vitamin C's role in immune support and cellular protection.
