About this product
The unsweetened, double-strength liquid in Superdose’s vitamin C range supplies 2000mg per 15ml. Its vitamin C comes from ascorbic acid, sodium ascorbate and calcium ascorbate in a sunflower-lecithin liposomal base. The flavour profile differs from the sweetened berry 1000mg option, so both serving strength and taste can help guide your choice. In this 75ml bottle, you have 5 measured 15ml servings.
The 75ml bottle is a compact way to try the format or keep a smaller bottle in your routine. Superdose uses liposomes formed from phospholipids in its liposomal range. This describes the delivery format and is not a guarantee of a particular result.
What it’s designed to support
Superdose designed this concentrated vitamin C formula for immune and antioxidant support. Vitamin C contributes to normal collagen formation and energy metabolism as part of its everyday nutritional roles. The higher concentration is a format choice to review against your individual needs.
Who it’s for / Before you buy
May suit customers who want a higher-strength vitamin C liquid without added sweeteners. Follow the instructions for this exact formula rather than those for another Superdose bottle. Seek advice about kidney stones, excess iron, pregnancy, breastfeeding and medicine use before buying.
What to compare
The key distinction is 2000mg in a 15ml serving. Original glass Poten-C has the same vitamin C amount in 25ml, while the berry liquid provides 1000mg in 15ml. Compare taste, serving size and how much you expect to use within the opening period. 75ml supplies 5 servings at 15ml per serving.
