Protein Supplies Australia Vitamin C Unflavoured 100g is a single-ingredient ascorbic acid powder for shoppers who prefer a measured powder format over tablets or capsules.

The 100g pouch is compact for cupboard storage and gives flexible serving control. The powder is unflavoured but naturally tart, so many shoppers prefer mixing it into juice, smoothies or another flavoured drink rather than plain water.

This product is best compared with tablet, capsule and flavoured vitamin C products by ingredient list, serve control, taste preference and whether you are comfortable measuring powder. It does not include added flavours or sweeteners.

The powder format is useful when you want to mix into drinks you already use, but it also needs careful handling because serve sizes are small. Keep the pouch tightly sealed and use a dry spoon or scoop.

Measure the labelled serve carefully and keep the pouch sealed after opening. Review the warning panel before purchase, especially if pregnant, breastfeeding, taking medication or buying for children.

For comparison, focus on tart taste, serving accuracy, single-ingredient format and whether measured powder suits you better than tablets.
