Biotic Extra — Mushrooms, Botanicals & Immune Nutrients for Multi-Layered Daily Immune Support
Biotic Extra is one of Priority One's most comprehensive immune formulas — combining therapeutic mushroom extracts, a broad spectrum of immune-supportive botanicals, prebiotic fibre, and key vitamins and minerals into a single daily formula. Rather than focusing on one mechanism, it is designed to support immune function across multiple pathways simultaneously: immune cell activation, gut-associated immune tissue, microbial balance, antioxidant protection, and foundational nutrient support.*
Serving size is 3 vegetarian capsules, 30 servings per container (90 capsules).
What's inside and why it matters
Vitamin A as Beta-Carotene (3,000mcg RAE) — Beta-carotene is a provitamin A carotenoid that the body converts to Vitamin A as needed. Vitamin A is essential for maintaining the integrity of mucosal barriers — the body's first line of immune defence — and supports normal immune cell development and healthy mucosal immunity.*
Vitamin C as Ascorbic Acid (400mg) — A well-established immune-supportive nutrient and antioxidant. At 400mg per serving, this is a clinically meaningful dose that supports normal immune cell function, white blood cell activity, and antioxidant protection during periods of immune demand.*
Vitamin B6 as Pyridoxine HCl (15mg) — An essential cofactor for normal immune cell production, including lymphocytes and antibodies. Vitamin B6 supports the body's ability to mount and regulate a normal immune response.*
Magnesium as Magnesium Bisglycinate Chelate (15mg) — Magnesium bisglycinate is a highly bioavailable chelated form of magnesium, better absorbed than oxide or carbonate forms. Magnesium supports normal immune signalling and hundreds of enzymatic processes that underpin healthy physiological function.*
Zinc as Zinc Gluconate, fully reacted (15mg) — Zinc gluconate is a well-absorbed form of zinc. Zinc is one of the most critical minerals for immune function, required for the normal development and activation of T-cells, NK cells, and macrophages, and plays a direct role in antioxidant defence.*
Beta (1,3)-(1,6) D-Glucan 70% (15mg) — The (1,3)-(1,6) linkage form of beta-glucan derived from yeast is recognised as the most biologically active form for immune modulation. It binds to pattern recognition receptors on macrophages and NK cells, supporting normal innate immune priming and activation.*
Bioflavonoids 90% extract from Bitter Orange fruit (200mg) — A high-potency bioflavonoid extract delivering a concentrated dose of citrus polyphenols. Bioflavonoids support the activity of Vitamin C, provide antioxidant protection, and contribute to healthy capillary integrity and vascular support.*
Larch Arabinogalactan, wood (Larix spp., 450mg) — The highest-dosed ingredient in this formula. Larch arabinogalactan is a prebiotic polysaccharide that supports gut-associated lymphoid tissue (GALT) — the largest component of the immune system, located in the intestinal lining. By supporting the gut immune environment, larch arabinogalactan helps reinforce immune function at its most foundational level.*
Myrrh gum-resin extract 4:1 (Commiphora molmol, 40mg) — A resinous botanical used in traditional medicine across multiple cultures for its role in supporting immune and mucosal health. The 4:1 extract ratio means each 40mg dose is equivalent to 160mg of raw material.*
Ginger root extract 4:1 (Zingiber officinale, 30mg) — Ginger contains gingerols and shogaols, bioactive compounds with a long history of traditional use for supporting immune comfort and respiratory wellness. 4:1 extract concentration.*
Garlic bulb (Allium sativum, 150mg) — One of the most widely researched medicinal plants, garlic's organosulfur compounds — particularly allicin and its derivatives — are well established for their role in supporting immune and respiratory health.*
Barberry root extract 4:1 (Berberis vulgaris, 40mg) — A source of berberine, a plant alkaloid with a long history of use for supporting healthy microbial balance and gastrointestinal wellness. 4:1 extract concentration.*
Oregon Grape root extract 4:1 (Mahonia aquifolium, 150mg) — Another berberine-containing botanical, Oregon Grape has a long tradition of use for supporting immune and microbial balance in the digestive tract. 4:1 extract concentration.*
Grapefruit Seed extract 4:1 (Citrus × paradisi, 35mg) — Traditionally used for its role in supporting a healthy microbial environment. 4:1 extract concentration.*
Olive Leaf extract 20% Oleuropein (Olea europaea, 125mg) — Standardised to 20% oleuropein — the primary active compound in olive leaf — this is a meaningful, potency-verified dose. Oleuropein is well researched for its role in supporting normal immune function and healthy microbial balance.*
Shiitake whole mushroom extract 4:1 (Lentinula edodes, 35mg) — Shiitake is rich in beta-glucan polysaccharides including lentinan, which supports normal immune cell activation. Whole mushroom extract, 4:1 concentration.*
Maitake whole mushroom (Grifola frondosa, 125mg) — Maitake contains D-fraction beta-glucan polysaccharides that support normal immune cell function, particularly macrophage and NK cell activity.*
Cordyceps sinensis mycelium extract 4:1 (Ophiocordyceps sinensis, 300mg) — The highest-dosed mushroom in this formula. Cordyceps supports normal immune modulation, healthy energy metabolism, and normal oxygen utilisation. The 4:1 mycelium extract provides a concentrated dose of this well-researched functional mushroom.*
Three layers of immune support in one formula
Biotic Extra works across three complementary levels. The vitamins, minerals and beta-glucan provide foundational immune cell nutrition and activation support. The mushroom trio — Cordyceps, Maitake and Shiitake — reinforces innate immune function through beta-glucan-mediated immune cell priming. And the botanical complex — Oregon Grape, Barberry, Olive Leaf, Garlic, Grapefruit Seed, Myrrh and Ginger — supports healthy microbial balance and gut immune integrity alongside the Larch Arabinogalactan. The result is a formula that supports immune health from multiple directions simultaneously.*
