What Are Immune Support Supplements?

Nutrition and immune health are closely related. Along with factors like exercise, sleep, and stress management, the body’s ability to maintain healthy immune function largely relies on a balanced diet. Nutrients influence the body’s immunomodulatory processes, and the deficiency of even a single nutrient can potentially alter the body’s immune response. This is where immune support supplements can help.

The best immune support supplement helps maintain immune function through the optimal absorption of high-quality ingredients. Tesseract’s advanced formulations and revolutionary nutrient delivery system, according to our Three Pillar Approach — maximum absorption, enhanced palatability, and microdosing — enhance the therapeutic potential of nutritional supplements to support your body’s healthy immune function.

Why Choose Tesseract Immune Support Supplements?

Tesseract’s proprietary CyLoc® technology protects the integrity of active ingredients by encasing each molecule in its own dextrin fiber delivery cage. The DexKey® release technology accompanying each CyLoc® molecule releases the active ingredient at the desired point within the GI tract, ensuring optimal absorption and effectiveness of the ingredients. With the CyLoc® - DexKey® matrix, ingredients can be precisely delivered and optimally absorbed, which means lower doses can be used to create rapid and powerful physiological responses that support healthy immune function.

Tesseract Formulas Support Healthy Immune Function

The following advanced immune support supplements are formulated with trusted nutrients delivered through Tesseract’s revolutionary nutrient delivery system:


Available in both quick-release and sustained-release formulations, BerberActiv® contains Berberine, a compound extracted from the roots of the plant Berberis aristata. Recent studies reveal the therapeutic potential of berberine for supporting healthy immune function1 and healthy blood glucose metabolism.*2 Berberine is also associated with maintaining healthy lipid metabolism, gastrointestinal health, liver function, cardiovascular function, and healthy weight management.* With Tesseract’s innovative delivery technology, BerberActiv® optimizes the absorption of berberine—one molecule at a time.

QuerciSorb Immuphore SR

QuerciSorb Immuphore SR™ contains four immune-supportive nutrients in a single capsule that promote healthy immune function throughout the day*:

  • Quercetin

  • Zinc

  • Vitamin D

  • Vitamin C

Quercetin, a powerful antioxidant, modulates the body’s natural inflammatory response and requires binding with zinc to exert its beneficial effects on immune function. However, both quercetin and zinc are typically poorly absorbed. Tesseract’s proprietary delivery technology changes that, optimizing their therapeutic benefit.*

QuerciSorb Immuphore SR™delivers active ingredients through the gut wall in a sustained-release (SR) format to support healthy immune function all day long.*

Front of TetraCumin® SR bottle


Curcumin and its metabolites have long been used to support healthy inflammatory responses in the body.* However, the poor absorption of curcumin when taken orally adversely impacts its efficacy. Tesseract’s TetraCumin® formulation utilizes tetrahydrocurcumin, the highly bioactive metabolite of curcumin and a powerful antioxidant.* Combined with Tesseract’s unique delivery technology, TetraCumin® ensures better absorption and enhances the therapeutic potential of tetrahydrocurcumin to support immune function, gastrointestinal health, cardiovascular health, and optimal lipid profiles.*
