Ingredient Highlights

  • Bifidobacterium longum BB536™ – This patented bacterial strain may help provide remarkable improvements in immune function.*
  • Bifidobacterium lactis Bl-04™ – This powerful proprietary bacterial strain may help increase levels of the natural killer (NK) and T cells that are vital to the immune system’s ability to fend off invaders.*
  • Lactobacillus acidophilus  The most versatile of the probiotic strains, it is resistant to low pH and has a high reproduction rate that maximizes intestinal protection.*
  • Bifidobacterium longum – This beneficial bacterium helps normalize the digestive track and fights the growth of other, less desirable bacterial strains.*
  • Bifidobacterium bifidum  One of the major strains that make up colon flora and is known to improve digestive function.*
  • Lactobacillus casei – This powerful bacterial strain helps to reduce flatulence and promote regularity.*
  • Lactobacillus rhamnosus – Has a unique ability to limit the growth of bad bacteria and support the immune system.*
  • Lactobacillus plantarum  Synthesizes l-lysine, an amino acid that promotes calcium absorption and helps to mitigate the effects of antibiotics on good bacteria.*
  • Western Larch Fiber  – Also known as larch arabinogalactan, is a fiber that comes from the bark of the larch tree found growing in western North American mountains. It has been shown to help increase intestinal flora and promote immune health.*
  • Beet Root Fiber  – Beets have traditionally been known as a nutrient-rich food. While its cardiovascular health and antioxidant benefits are widely acknowledged, beet root also contains fiber that is useful in promoting the growth of health gut bacteria.*
  • Artichoke Fiber  – Artichoke is a strong bitter that stimulates digestion, absorption and intestinal elimination. Artichoke provides a natural source of inulin and oligosaccharides and is commonly used as a prebiotic.*
  • Dandelion Root  – Dandelion is a rich source of vitamins, minerals, flavonoids, choline and inulin, which is a natural herbal prebiotic that promotes the growth of healthy flora. The bitter compounds in the root also help stimulate digestion and bile production and flow. The increase in bile flow may help promote fat (including cholesterol) digestion in the body.*
  • Burdock Root  – Contains high levels of inulin, a fiber known to promote growth of healthy bacteria. Burdock root is known to have soothing effects on the gastrointestinal tract and has been traditionally used to promote digestion.*
