Premium Vitamin C supplements at BIOGENA

Vitamin C is essential – but your body can’t make it on its own. That’s why it’s so important to get enough of it every day – through a balanced diet or, when needed, with targeted, high-quality vitamin c supplements. At BIOGENA, you’ll find a wide range of premium vitamin C options: from easy-to-take vitamin c capsules to liquid drops – all rigorously tested and crafted to meet our highest quality standards.

Vitamin C supplements, your way – in trusted BIOGENA quality

Whether you're looking for plant-based vitamin C, high-dose support, or cutting-edge liposomal formulas – BIOGENA has the full range to match your individual needs. What unites them all? Uncompromising quality.

Our vitamin c products are developed by our expert science team, made with premium raw materials, and tested to meet the highest standards. And just as important: our formulas are as pure as possible – free from unnecessary additives like preservatives, emulsifiers, or artificial colorants. That makes them especially well tolerated – even by sensitive individuals.

Why vitamin C supplements can make sense

Your body needs vitamin C every single day – but it can only store small amounts. During certain life phases or in times of increased demand, like stress, intense exercise, or smoking, a targeted vitamin C supplement can help support your daily supply.

Looking for a high-quality option? At BIOGENA, you’ll find a carefully curated selection of premium vitamin C supplements – made to fit your lifestyle and your needs.

Vitamin capsules, tablets, powder or drops – which format fits you best?

Everyone’s different – and so are their preferences. Here’s a quick guide to help you choose the right fit:

  • Capsules & tablets – easy to dose, taste-neutral, and perfect for everyday routines

  • Powder – great for flexible dosing and easy to mix into water or smoothies

  • Drops & effervescent tablets – ideal if you prefer a liquid alternative

Our tip: Vitamin C capsules are a great choice – especially because they’re free from unnecessary additives.

How does your body absorb vitamin C best?

The key lies in bioavailability – in other words, how efficiently your body can absorb and use the vitamin. And that depends on the form:

  • Liposomal Vitamin C: Thanks to its special phospholipid shell, this form is particularly well absorbed. Studies show it delivers up to 2.4 times higher blood levels compared to traditional vitamin C powder.

  • Ester-C®: Also known for its excellent bioavailability, Ester-C® contains L-threonate, which helps it stay longer in immune cells. Plus, it’s especially gentle on the stomach – a great option for sensitive individuals.

What’s the most stomach-friendly form of vitamin C?

Buffered vitamin Clike calcium ascorbate – is combined with alkaline minerals, making it less acidic. That means it’s easier on your stomach and gentler on your teeth. A smart choice for anyone with a sensitive system.
