Martin & Pleasance Ki Immune Defence Extra Details

Martin & Pleasance Ki Immune Defence Extra is the stronger, standardised member of the Ki immune range. Each tablet combines astragalus root and maitake mushroom — both standardised to at least 40% polysaccharides — with shiitake mushroom, olive leaf and 7 mg of zinc. The astragalus is an 18:1 extract (Rhina-MP) at 277.83 mg, equivalent to 5 g of dried root. The brand says it is specially formulated to provide 40% polysaccharides through standardised ingredients that work with your body to support the immune system. Each pack holds 45 tablets for adults, free from dairy, wheat, gluten and animal products.

Who Ki Immune Defence Extra Is For

  • Adults who want a more concentrated immune formula than the original Ki Immune Defence & Energy
  • People who value standardised extracts with a stated polysaccharide content
  • Those who want zinc built into their herbal immune formula
  • Anyone heading into a busy season, travel or time around people who are getting sick
  • Shoppers avoiding dairy, wheat, gluten and animal products

Who this product is NOT for:

  • Anyone taking warfarin — the brand says not to use it during warfarin therapy
  • Children — the formula is for adults only
  • People with an auto-immune disorder, diabetes or a kidney disorder, or taking blood thinners or diuretics, unless a healthcare practitioner has approved it
  • Women who are pregnant or breastfeeding, unless advised by a healthcare professional

Vitamart's Take

Ki Immune Defence Extra is what we point people to when they like the idea of the Ki range but want more muscle behind it. The difference is in the detail: standardised astragalus and maitake with a stated 40% polysaccharide content, plus 7 mg of zinc in every tablet, on top of the shiitake and olive leaf from the original formula. It's still a daily support product rather than something for the first day of a cold. Note the cautions: it isn't for anyone on warfarin, and people with auto-immune or kidney conditions should check with a practitioner first.

How Ki Immune Defence Extra Compares

Ki Immune Defence Extra vs. Ki Immune Defence & Energy

The original formula has astragalus, shiitake and olive leaf. Extra adds maitake mushroom and 7 mg zinc, and standardises astragalus and maitake to at least 40% polysaccharides.

Extra vs. Ki Cold & Flu Attack

Ki Cold & Flu Attack is an andrographis, ginger and zinc formula taken at the first sign of infection. Extra is designed for ongoing support before you get sick.

Herbal blend vs. zinc on its own

A plain zinc supplement gives you the mineral alone. Extra pairs 7 mg zinc with four standardised herbal and mushroom extracts in one tablet.

What Is Maitake Mushroom?

  • Maitake (Grifola frondosa) is an edible mushroom that grows in clusters at the base of trees, sometimes called hen of the woods
  • It has been used for centuries in Japanese and Chinese traditional medicine
  • Mushrooms like maitake and shiitake are rich in polysaccharides, complex carbohydrates that are the focus of much immune research
  • In Ki Immune Defence Extra, maitake is standardised to at least 40% polysaccharides, as is the astragalus
  • Maitake is the ingredient that separates Extra from the original Ki Immune Defence & Energy Formula

Recommended Purpose

  • Specially formulated to provide 40% polysaccharides through standardised ingredients that work with your body to support the immune system
  • Supports your immune system's ability to respond quickly

How To Use

  • Adults: take 1 tablet daily with food, or as directed by your healthcare practitioner (the brand's site allows 1 tablet once or twice daily — follow the directions on your pack)
  • Take a few hours before or after other medications
  • Do not take during warfarin therapy
  • Consult a healthcare practitioner first if you are pregnant or breastfeeding, have an auto-immune disorder, diabetes or a kidney disorder, or take blood thinners or diuretics
  • A diuretic effect may occur; discontinue use if you develop a sensitivity or allergy to the formula
