Ingredients & the Science Behind Trizenca
Six immune actives in one daily stick pack
Trizenca® Triple Immune Defense combines six well-studied nutrients and botanicals chosen for their role in everyday immune support: Vitamin C, Zinc, Vitamin D3, Elderberry, Quercetin, and Echinacea. Below is a plain-English look at what each one is, the role it plays in the body, where it’s found in food, and how much is in every serving. Information here is drawn from public sources including the U.S. National Institutes of Health Office of Dietary Supplements (NIH ODS).
Vitamin C (Ascorbic Acid) — 1000 mg
Vitamin C is a water-soluble essential nutrient and one of the most recognized antioxidants in the diet. The body can’t make it on its own, so it has to come from food or supplements. It acts as an antioxidant that helps protect cells from free radicals, supports the normal function of the immune system, and is needed to make collagen, the protein your body uses for skin, blood vessels, and wound healing. Vitamin C also improves the absorption of iron from plant foods.
Food sources
Citrus fruits, strawberries, kiwi, bell peppers, broccoli, tomatoes, and leafy greens. The recommended daily amount for adults is roughly 75–120 mg, with an upper limit of 2,000 mg per day for adults.
In Trizenca
Each serving provides 1000 mg of Vitamin C — a robust daily dose well within the established safe upper limit.
Zinc — 12 mg
Zinc is an essential trace mineral involved in hundreds of processes in the body. It’s important for a healthy immune system, for making proteins and DNA, for wound healing, and for a normal sense of taste and smell. Because the body has no large store of zinc, a steady daily intake matters.
Food sources
Oysters and other shellfish, meat, poultry, beans, nuts, seeds, whole grains, and dairy. The recommended daily amount for adults is about 8–12 mg, with an upper limit of 40 mg per day.
In Trizenca
Each serving provides 12 mg of zinc to support normal immune function as part of a daily routine.
Vitamin D3 (Cholecalciferol) — 25 mcg (1,000 IU)
Vitamin D is the “sunshine” nutrient — your skin makes it when exposed to sunlight — but many people fall short, especially in winter or with limited sun exposure. It’s essential for healthy bones and for normal immune function. D3 (cholecalciferol) is the form the body uses most efficiently.
Food sources
Fatty fish like salmon and sardines, fish-liver oils, egg yolks, and fortified foods such as milk. The recommended daily amount for adults is about 600–800 IU (15–20 mcg), with an upper limit of 4,000 IU for adults.
In Trizenca
Each serving provides 25 mcg (1,000 IU) of Vitamin D3 to help maintain immune and bone health.
Elderberry (Sambucus nigra) — 100 mg
Elderberry is the deep-purple fruit of the European elder tree and a traditional botanical long used in wellness routines. It’s naturally rich in flavonoid antioxidants called anthocyanins, the pigments that give the berries their dark color. Elderberry is traditionally used to support the immune system, and properly manufactured elderberry extract is considered safe.
In Trizenca
Each serving provides 100 mg of elderberry extract, delivering its signature flavonoid antioxidants in a clean, ready-to-mix form.
Quercetin — 100 mg
Quercetin is a plant flavonoid and one of the most abundant antioxidants in the everyday diet. It functions as an antioxidant that helps neutralize free radicals and supports the body’s normal, healthy inflammatory response. It’s frequently paired with Vitamin C in immune formulas because the two are complementary antioxidants.
Food sources
Onions, apples, berries, capers, grapes, leafy greens, and tea. A typical diet provides only a small amount (roughly 10–100 mg per day), which is why it’s a popular addition to supplements.
In Trizenca
Each serving provides 100 mg of quercetin to complement the antioxidant role of Vitamin C.
Echinacea — 200 mg
Echinacea is a flowering herb (the purple coneflower) native to North America and one of the most popular botanicals for immune support. It has a long history of traditional use and is widely included in immune-support products.
In Trizenca
Each serving provides 200 mg of echinacea, rounding out a six-active blend built for daily use.
Why these six work together
Rather than relying on a single nutrient, Trizenca layers complementary actives: two foundational immune vitamins (C and D3), a key immune mineral (zinc), and three plant antioxidants and botanicals (elderberry, quercetin, and echinacea). Vitamin C and quercetin act as paired antioxidants; zinc and Vitamin D3 support normal immune function; and the botanicals add traditional immune-support ingredients people already reach for during the season — all in one great-tasting stick pack with no added sugar.
How to use Trizenca
Tear open one single-serve stick pack, stir it into 8–12 oz of cold water, and drink. It’s designed for convenient daily use — at home, at your desk, or on the go.
