Collection: Immune System Supplements

Quantum Health has offered high-quality immune system support supplements for decades and has been trusted by families since we opened our doors in 1981. We offer multiple lines of immune health support supplements in a variety of formulations and delivery formats.

SuperLysine+

Our SuperLysine+ family of products is our oldest product line. While many of the products in this family are focused on cold sore medicines and care, other products are formulated as supplements for immune health.

SuperLysine+ Tablets, which are available in 90 and 180 count sizes, are the top-selling, lysine based, immune system support supplements in the US and Canada. In addition to lysine, these tablets are also formulated with vitamin C, garlic, echinacea, and other ingredients that work together to keep your immune system in tip-top shape. Many people who use SuperLysine+ ointment also choose to take the tablets daily for a complete solution.

For those who are looking for vegetarian immune system support supplements, there is SuperImmune+. Also formulated with Lysine, these immunity supplements are completely vegetarian and include astragalus root extract and olive leaf extract.

Finally, SuperLysine+ is also available as a liquid extract, which is the most bio-available, high uptake form we offer. It includes a proprietary blend of lysine and other ingredients including shiitake mushroom extract.

TheraZinc

Just about everyone understands the immune-supporting benefits of zinc gluconate lozenges. But did you know that Quantum Health was the very first company to commercially offer zinc gluconate for immune system support?

Back in 1984, Dr. George Eby published a research paper that showed clear evidence that zinc gluconate lozenges could act as immune system support when the immune system was compromised. Just one year later in 1985, Quantum Health launched a line of zinc gluconate lozenges under the TheraZinc brand name.

Today, our TheraZinc line includes multiple flavors and formulations of zinc gluconate lozenges, along with our award-winning oral spray that delivers a full dose of zinc gluconate directly to the throat, where it is needed most. Our newest addition to the TheraZinc line is our USDA Organic lozenges. These lozenges come in both Elderberry and Blood Orange varieties and are formulated to taste great while delivering the zinc gluconate your body needs for effective immune support.

Elderberry

Sambucus nigra elderberry has been recognized for its immune system supporting benefits for thousands of years. In modern times, it was Dr. Madleine Mumcuoglu, an Israeli virologist, who first scientifically documented the efficacy of this potent herbal extract.

Elderberries are high in vitamin C and in other antioxidants, which are known to aid the immune system. Elderberry also seems to suppress the ability of hemagglutinin proteins to attach to cells. When the immune system is under stress, these proteins can attack immune cells, reducing their ability to properly function and protect the body. Taking elderberry immune system support supplements can tip the balance in the favor of your immune system.

Sambucus nigra elderberry also contains phytonutrients. These are chemicals that are produced by plants and found in high doses in brightly colored food like the fruits and vegetables in a healthy diet. Phytonutrients are part of the plant’s natural immune system and help the plant resist outside threats. Over time, consuming phytonutrients seems to positively influence our own immune systems as well.

Our elderberry immune system support supplements include 4 different products. Our liquid extract is an elderberry only tincture that provides the highest per serving dose of elderberry in the most bioavailable, high uptake form. Our syrup is formulated with Sambucus nigra elderberry, along with a host of other nutrients that offer immune support. It also soothes the throat and tastes great. Finally, our capsules and lozenges round out our line, so no matter what form you prefer in your elderberry immune system support supplements, we have you covered.

We also include Sambucus nigra elderberry in many of our TheraZinc products, including our TheraZinc elderberry lozenges and our oral spray. Elderberry is also a key ingredient in our Immune Support line.

Immune Support

Finally, we offer two other immune system support supplements in our product line. Immune Support liquid extract is formulated with echinacea, elderberry, and goldenseal in a high uptake, tincture form. The same formula is also available in our Immune Support capsules for those who prefer to swallow capsules instead.

Cough Relief

While not technically supplements for immunity, Quantum Health offers the only USDA Organic cough drops available anywhere. Our cough relief drops are available in two premium flavors, Meyer Lemon and Honey and Bing Cherry. They are great for quieting a cough and soothing a sore or scratchy throat when you are under the weather with a cold or the flu, and are the right choice for anyone who is looking for a cough drop made from high-quality ingredients and who prefers USDA Organic products. Once your throat is soothed, you can get the much needed sleep you deserve.

Choosing the Right Immune System Support Supplements

When you choose any supplement, you should make sure that it is a formula that is backed by science. That means, it should include scientifically studied ingredients in the right doses and proportions. Also, it is wise to choose immune system support supplements from a company that has a long track record of delivering the best products that families can trust.
