Swanson MicroLactin Double Strength has emerged as a premier nutritional supplement for joint health maintenance, and for good reason. Nature's most effective joint health breakthrough in a double strength formulation! This remarkable supplement is made up of concentrated micronutrients and proteins derived from cow's milk. And since MicroLactin and the popular joint supplement glucosamine work by different mechanisms, they can be used together for even better results! Swanson MicroLactin Double Strength packs a potent 1,000 mg into each tablet, twice the amount found in our Swanson MicroLactin capsules. That means you get the same level of joint support in half the number of pills.
