Focused Immune Support. In a Stick Kids Will Actually Take.
Immune Defense combines four familiar ingredients in a simple citrus stick pack made for school days, travel, and busy family routines.† The formula is focused, portable, and — just as important — tastes good enough to use consistently.
Zinc + Vitamin D3
5 mg elemental zinc from zinc glycinate plus 400 IU (10 mcg) vitamin D3 to support normal immune function.†
Vitamin C + Elderberry
75 mg vitamin C plus 50 mg elderberry complete the focused four-ingredient immune-support blend.†
Citrus Kids Actually Like
An orange-lemon citrus direction that came out very well in sampling — important because a formula only helps the routine if kids will actually take it.
Simple by Design
Four ingredients. Clear amounts. A practical format. We wanted Immune Defense to feel easy to understand and easy to use — without turning the label into a long list of trendy extras.
Zinc Glycinate — 5 mg
Each stick provides 5 mg elemental zinc from zinc glycinate. We chose to show the exact form and elemental amount clearly rather than relying on a branded mineral name.
Vitamin D3 — 400 IU
10 mcg (400 IU) vitamin D3 per stick, included as part of the formula’s everyday immune-support foundation.†
Vitamin C — 75 mg
A meaningful amount of vitamin C in each stick to complement zinc and vitamin D3.†
Elderberry — 50 mg
50 mg elderberry rounds out the formula without overwhelming a simple, focused ingredient list.
30 Portable Sticks
One box contains 30 individually portioned 3-gram sticks for school bags, travel, sports weekends, and busy family routines.
Taste Matters
The citrus flavor is bright and easy to take. We paid particular attention to smoothing the mineral taste so the finished sample still tastes good.
Why I Made This
As a pediatrician and a mom, I wanted an immune-support product that made sense for the way families actually live.
School mornings get rushed. Travel changes routines. Kids have practices, games, sleepovers, and long days away from home.
So the format mattered almost as much as the formula.
I wanted a focused blend I could explain clearly: 5 mg zinc, 400 IU vitamin D3, 75 mg vitamin C, and 50 mg elderberry — in a citrus stick that was easy to pack and actually tasted good.
That’s what Immune Defense is meant to be: thoughtful daily support in a format that goes where family life goes.

Why We’re Building It This Way
Why zinc glycinate?
We chose zinc glycinate as the zinc source and provide 5 mg elemental zinc per stick. The form is clearly named on the label so parents can see exactly what they are giving their child.
Why include vitamin D3?
Each stick provides 400 IU (10 mcg) vitamin D3. Vitamin D supports normal immune function and complements zinc as part of the formula’s core.†
Why add vitamin C and elderberry?
Vitamin C supports normal immune function.† We included elderberry as an additional botanical ingredient to keep the blend focused. The planned amounts are approximately 75 mg vitamin C and 50 mg elderberry per stick; final amounts will be confirmed on the production label.
Is this only for when kids are sick?
No. The product is intended for daily nutritional support, not to prevent or treat illness. We designed the stick format especially for school, travel, and other busy periods when families want something easy to keep in the routine.†
What flavor are you developing?
We’re developing a citrus flavor inspired by orange and lemon, with attention to balancing the natural taste of zinc. We’ll share the final flavor details after production approval.
TESTING & TRANSPARENCY
Finished-Batch Testing Coming With Production
