The 1kg jar offers a significantly better price per gram than the 500g size, several months of stock for daily use with no frequent reordering, and the same fully adjustable, personalised dosing suited to every member of the family. It also reduces packaging waste compared with buying several smaller jars.

Dissolve 1/2 to 2 measuring scoops (500mg–1g) in a large glass of water, fresh fruit juice, a smoothie, or even cold fruit purée. Take it in the morning or early afternoon, as its mild stimulating effect could disturb sleep for sensitive people if taken late. For higher doses, split intake across two or three times a day rather than one large dose — vitamin C is water-soluble, so the body naturally eliminates any excess. Avoid mixing the powder into hot drinks, as heat partially degrades vitamin C.

Vitamin C is an essential nutrient the body cannot make itself. It contributes to normal immune function, reduced tiredness and fatigue, and normal energy metabolism. It’s a powerful antioxidant that helps protect cells from oxidative stress, supports the absorption of non-haem iron (a plus for vegetarians and those with limited iron intake), and contributes to normal collagen formation, essential for blood vessels, bones, cartilage, gums, skin and teeth.

Made to HACCP standards with quality checks at every production stage, prioritising plant-based raw materials with no superfluous ingredients.

Do not exceed the recommended daily dose. Consult a healthcare professional if pregnant, breastfeeding, or on medication. Not recommended for people with haemochromatosis (iron overload) or a history of oxalate kidney stones. This food supplement is not a substitute for a varied and balanced diet and a healthy lifestyle. Keep out of children’s reach.

1kg vs. 500g — how do I choose?

If you’re new to vitamin C powder, the 500g size is a good starting point. If you’re already a regular user or want to share the jar with your family, the 1kg format offers a better price per gram.

Can I use it in cooking?

Yes, in cold preparations like smoothies, juices, purées, yoghurts or fruit salads. Avoid hot or cooked preparations, as heat degrades vitamin C and reduces its effectiveness.

How should I store it?

Reseal the jar tightly after each use and store in a dry place away from direct light and heat — humidity is vitamin C powder’s main enemy, as it can cause clumping and reduce quality.
