About this product
A berry-flavoured liquid with glutathione, vitamin C and selenium in one measured serving. Every 15ml provides 500mg L-glutathione, 200mg vitamin C and 50 micrograms selenium. Superdose uses a sunflower-lecithin liposomal format. It may appeal to customers who prefer liquid supplements and want to compare a combined antioxidant formula with individual nutrients. In this 450ml bottle, you have 30 measured 15ml servings.
Choose the bottle size to suit your expected use; refrigerate after opening and follow the pack storage instructions. 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 positions this formula around cellular resilience and antioxidant wellbeing. The added vitamin C and selenium support normal immune function and the body’s defences against oxidative stress. It offers everyday nutritional support without promising a particular cosmetic result.
Who it’s for / Before you buy
An option for adults who find a liquid easier to take than capsules. Before buying, check the selenium in any other supplements you use, as this bottle supplies 50 micrograms per adult serving. Pregnancy, breastfeeding, medicines and existing health concerns warrant individual advice.
What to compare
Check the glutathione amount alongside the other nutrients. Two products with similar names may differ in selenium, vitamin C and serving volume. Use the stated daily serving when comparing value and remember to refrigerate the opened bottle. 450ml supplies 30 servings at 15ml per serving.
