Ultra-high absorption for everyday feel-good

Vitamin C is one of the most researched nutrients in the world, yet many people still don’t get the most from it. Traditional tablets and powders often pass through the body with limited uptake, meaning much of what you take is never fully used.

At Zooki HQ, we believe Vitamin C should work harder. That’s why we use advanced liposomal delivery, designed to protect Vitamin C as it passes through the digestive system so more can be absorbed — and so you can actually feel the benefits.

What is Zooki Vitamin C?

Zooki Vitamin C is a daily sachet designed to support immune health, energy and everyday wellbeing, delivering Vitamin C in a form your body can actually use.

Vitamin C plays an important role in reducing tiredness and fatigue, and supporting normal immune function and cognitive function.

Each sachet delivers a high-strength dose of Vitamin C and is better absorbed than standard Vitamin C tablets or powders thanks to Zooki liposomal encapsulation.

This means the Vitamin C is wrapped in tiny fat-like bubbles, helping protect it as it passes through the digestive system so more can be absorbed and used by the body.

Ingredients & nutritional information

Unlike many liquid supplements, this formula contains no artificial flavourings, sweeteners or preservatives, only carefully selected ingredients for a clean, natural taste.

Ingredients (shared across all flavours):

  • Glycerin (Coconut-Sourced) - a natural humectant from coconuts that helps maintain moisture and stability in the liquid.
  • Vitamin C Proprietary Blend (Sunflower Oil containing Phosphatidylcholine and Vitamin C as L-Ascorbic Acid) - a specialised blend designed for enhanced absorption, combining essential Vitamin C with phospholipids to support immune health and collagen formation.
  • Purified Water - the base that carries all the other ingredients.
  • Natural Flavours (Citrus Oil and Vanilla) - provide a refreshing citrus taste with a smooth, rounded finish.
  • Vitamin E (D-Alpha-Tocopherol) - a natural form of vitamin E that supports antioxidant protection and overall health.
  • Natural Colours (Beta Carotene) - a plant-derived pigment that gives a natural golden-orange colour.
  • Potassium Bicarbonate - a mineral compound that helps maintain pH balance and contributes to a smooth taste.
  • Sucrose (Less than 0.1 g*) - a trace amount of natural sugar, present at less than 0.1 g per serving.
  • Oleic Acid - a naturally occurring fatty acid that supports stability of the formulation.
  • Citric Acid (Acidity Regulator) - found naturally in citrus fruits, balances flavour and helps preserve freshness.

Flavourings:

  • Citrus Orange - bright, juicy orange notes with a naturally zesty finish for a refreshing taste.
  • Watermelon - light, crisp, and subtly sweet, with the fresh, cooling flavour of ripe watermelon.

FAQs

Please read our FAQs page to find out more.

What's the best time of day to take Zooki Vitamin C?

We recommend taking Zooki Vitamin C early in the morning or mid-afternoon, so you can feel the energy-supporting benefits all day.

How is liposomal Vitamin C different to regular Vitamin C?

Zooki Liposomal Vitamin C contains vitamin C that has been wrapped in tiny lipid bubbles which increase the transport and absorption of the nutrient into the bloodstream, so you get more of the good stuff when and where it's needed. Our unique liposomal formula has been clinically proven to deliver up to 4x greater absorption vs. regular, non-liposomal supplements.

Is Zooki Vitamin C vegan?

Yes, this product is suitable for vegans.

Can I take it if I'm pregnant or breastfeeding?

We recommend those who are pregnant or breastfeeding consult with a health professional before adding a new supplement into their routine.

Is Zooki Vitamin C safe for children?

Vitamin C Zooki is generally safe for children, however we always recommend consulting with a medical professional before giving any dietary supplement to children under the age of 18. Young children under the age of 13 do not need a full sachet, and if they have too much it may temporarily upset their stomach. To manage how much to give to children, we recommend mixing with a small amount of water, adding it to yoghurt or giving it to them off a teaspoon. We recommend ages 4 - 8 have up to one teaspoon daily and children 8 - 13 have half a sachet.
