What's on the immune shelf?

  • Vitamins and minerals. Vitamin C, vitamin D3, vitamin A, zinc and selenium all support normal immune function.
  • Traditional herbs. Echinacea supports normal immune function. Astragalus root, olive leaf and cat's claw are traditionally used to support it. Elderberry provides anthocyanins that offer antioxidant support.
  • Functional mushrooms. AHCC, reishi and shiitake, with beta-glucan, support normal immune function.
  • From the gut. Lactobacillus probiotics support normal immune function, which is why a few gut formulas appear here too.

Respiratory support

Wild cherry bark is traditionally used to support normal respiratory function. Quercetin, a plant flavonoid, provides antioxidant support. The Specific goal filter gathers the respiratory formulas.

A steady daily routine

Your immune system works every day, not a few months a year. We'd rather help you build a simple daily routine than chase the newest trend. Start with the basics, like vitamin C, D3 and zinc, and add an herb if you want one.
