Discover the Fung Shui high-strength premium Birch Polypore liquid extract tincture. Also known as Piptoporus betulinus or the birch bracket fungus, birch polypore has been valued for centuries in traditional practices—famously carried by Ötzi the Iceman over 5,000 years ago. Our UK-grown, triple-extracted tincture pairs it with vitamin C and with zinc from guava leaf. Vitamin C and zinc both contribute to the normal function of the immune system and to the protection of cells from oxidative stress; zinc also contributes to normal macronutrient metabolism, while vitamin C contributes to the reduction of tiredness and fatigue. Discover clean, herbal supplements—no fillers or additives. Prefer great-tasting, bioavailable tinctures over birch polypore capsules or powder? You're in the right place. Clear instructions, clean ingredients and dosage guidance—triple-extracted, third-party tested, delivering 5000mg per dose, with a 90-day money-back guarantee. Ideal for both men and women as part of a balanced lifestyle.
