Blackcurrants are an excellent source of antioxidant anthocyanidins, polyphenols and vitamin C. Their potency may be three times greater than blueberries. Two capsule provide: 4mg pure astaxanthin from Haematococcus pluvialis, 100mg blackcurrant fruit 4:1, minimum 460mg tomato powder (natural source of lycopene), 6mg mixed carotenoids, 1.5mg rosemary leaf standardised extract (2-3% carnosic acid), ascorbyl palmitate vitamin E.
