Overview

A healthy immune system requires both adequate nutritional foundations and targeted support from compounds with demonstrated immunomodulatory effects. Double Wood's immune health collection spans essential minerals, medicinal mushrooms, and botanical extracts — each chosen for their evidence base and manufactured as single-ingredient products so you can build a protocol that matches your specific needs. Whether you are looking for year-round immune maintenance or additional support during high-stress periods, this collection covers both.

What To Look For

Immune support works on two levels: foundational and targeted. On the foundational side, Zinc Picolinate (a highly bioavailable zinc form), Vitamin D3+K2 Drops, and Quercetin address the nutritional deficits most commonly associated with impaired immune response. On the targeted side, Lion's Mane and Turkey Tail mushrooms are studied for their beta-glucan content and immunomodulatory effects. Astragalus is a traditional adaptogen with modern research supporting T-cell and NK cell activity. Colostrum and Ox Bile Salt support mucosal immunity in the gut. Mimosa Pudica Seed, Artemisinin, and Tiger Milk Mushroom round out the collection with more specialized immune applications.

Frequently Asked Questions

What are the best supplements for immune support?
For foundational immune support, Zinc Picolinate and Vitamin D3 are the most evidence-backed options — both have well-established roles in immune cell function and are among the most common deficiencies in adults. For additional support, Quercetin has antiviral and anti-inflammatory properties studied in multiple trials. Medicinal mushrooms like Lion's Mane and Turkey Tail provide beta-glucan-mediated immune modulation and pair well with the foundational minerals.
What is the difference between Lion's Mane and Turkey Tail?
Both are medicinal mushrooms with immune benefits, but their primary mechanisms differ. Lion's Mane (Hericium erinaceus) is best studied for brain and nerve support through NGF stimulation, with secondary immune effects. Turkey Tail (Trametes versicolor) is more specifically immunomodulatory — it contains PSK and PSP polysaccharopeptides that have been the subject of clinical research in immune health contexts.
How much Vitamin D should I take for immune health?
Most clinical research on immune benefits uses 2,000-4,000 IU of D3 daily. Double Wood's Vitamin D3+K2 Liquid Drops delivers D3 alongside K2 (as MK-7), which is important because high-dose D3 can increase serum calcium without adequate K2 to direct it to bones rather than soft tissue. A healthcare provider can test your 25-OH vitamin D levels to help calibrate the right dose for you.
