Zinc (Chelate)

   LIDTKE now offers Zinc as Bisglycinate Chelate from Albion Minerals, an advanced, more bioavailable and patented form of the essential mineral zinc. While most zinc supplements aren’t easily absorbed and can cause gastric upset, LIDTKE Zinc is chelated to produce small, organic molecules that pass easily through the digestive tract and are gentler on the digestive system. 

   Chelation naturally occurs during digestion, after stomach acid and enzymes break down protein into amino acids. LIDTKE Zinc is bound to an amino acid to form a chelate-complex, assisting transport through the intestinal walls. Interested in more in-depth information about LIDTKE Zinc?  LEARN MORE >

Super Immune’s Potent Nutrients

   Viruses are clever at survival. Many escape your immune system by coating themselves with fibrin. Super Immune takes a unique approach, working to dissolve this protective coating and remove the spikes that a virus uses to attach to a cell.


   This flowering plant has a long history combating respiratory viruses. Prior to  the introduction of antibiotics in 1950, echinacea held an esteemed medicinal status. 

Olive Leaf:

   For centuries, the olive tree has been known as the Tree of Life. Oleuropein, one of the active ingredients in olive leaf, works to reduce the reproduction of viruses.


   A phytonutrient-rich blend of superstar fruits and berries, abundant in Vitamin C, polyphenols, bioflavonoids, resveratrol, and other nutrients.


   Bromelain is the key enzyme found in pineapple stems. This concentrated proteolytic enzyme works to digest the protein in fibrin and biofilms protecting viruses, such as the corona virus.

Vitamin D:

   D-3 is the natural form your body makes from sunlight. Research demonstrates that vitamin D, especially at higher doses, supports excellent respiratory health.

Lidtke’s Berry-C
from Fruits & Berries

   A natural blend of superstar fruits and berries, bursting with flavor and abundant in natural Vitamin C, and other nutrients important to the immune system, skin, and eyes.

Acerola Cherries:

   One fruit contains 28 times the vitamin C of a lemon! Plus, vitamin C from acerola is 1.6 times more bioavailable than synthetic forms, meaning your body more easily and effectively utilizes this form of vitamin C.


   Strawberries are not only high in vitamin C and amazing health-protecting flavonoids, but are also one of the few organic sources of ellagic acid. Plants produce ellagic acid to defend against infection.


   Often called a superfood, blueberries are full of phytochemicals like resveratol, bioflavonoids, and anthocyanins and proanthocyanidins. 


   The high levels of proanthocyanidins, found in cranberries, help the body’s immune function by nurturing the lining of the gut, where a large part of the immune system is actually located.
