NAF BLK formulated for the nutritional support of blood, liver and kidneys, the body’s own de-toxifiers and cleansers. At times of extreme challenge, the liver and kidneys can show signs of stress, which is often reflected in poor blood profiles. By targeting these organs with specific herbal support, such as milk thistle, artichoke and dandelion, we can support the body’s own defence of these vital organs. BLK also includes scientifically verified, naturally sourced antioxidants to flush out the build up of free radicals within the system.
