Discover an immunity plan that equips your body’s “police force” to defend your health this Virus Season.
Your First Line of Defense
Think of your body, organs and cells as a community. Every day, foreign invaders—germs, viruses and toxins—try to slip past security. Who protects the community? Your immune system.
Like a police force, your immune system has layers of protection: commanders giving orders, officers patrolling, a SWAT team for emergencies and a cleanup crew restoring order. But just like any police force, it needs resources, training and backup to function at its best.
TriVita’s Vital Four Immunity Plan is designed to give your immune system that essential reinforcement. With Essential D™3, Elderberry, Zinc and new Revitalize Formula liver support, it equips multiple layers of defense to help you face Virus Season with strength and confidence.
Vitamin D3 – Training the Commanders
Your immune system’s T-cells are like commanders. They recognize threats and direct the troops. But without Vitamin D3, these commanders can’t even leave the station.
Vitamin D3 “activates” T-cells, ensuring your immune force knows what to fight and how to respond. Without it, invaders slip through unnoticed, leaving the city exposed. With it, your immune commanders stand tall and lead with precision.
Why it matters:
- Activates T-cells to recognize threats
- Slows biological aging
- Fewer autoimmune conditions and inflammation
If you’re often sick, slow to recover or feel drained during the winter months, your immune commanders may be undertrained.
Elderberry – Guarding the Gates
Every city needs strong guards at its gates. In your body, those gates are the respiratory passages where viruses often try to sneak in. Elderberry provides powerful plant compounds that help block viruses from multiplying and spreading.
Think of elderberry as the guard force that keeps enemies outside the city walls, giving your immune system the upper hand.
Why it matters:
- Helps reduce the severity and length of colds and flu
- Supports healthy respiratory tissue and function
- Acts quickly as a frontline symptom defense
If colds seem to linger or respiratory infections keep coming back, your immune gates may be underprotected.
Zinc – Equipping the Officers and SWAT Team
Even the best commanders and guards can’t hold a city without officers on patrol and a SWAT team for emergencies. Neutrophil (a type of white blood cells) and natural killer (NK) cells fill that role in your immune system… and they rely on zinc.
Zinc equips these first responders with the energy and tools to rush to the scene, stop invaders in their tracks and restore peace. TriVita’s Zinc contains a specialized form called OptiZinc®, which has been shown to absorb better than other forms of zinc. Without zinc, response times slow, and infections take hold.
Why it matters:
- Supports immune cells to attack viruses and bacteria
- Speeds healing of wounds and injuries
- Essential for normal function of the immune system
If you’re experiencing slow wound healing, frequent sore throats or recurring infections, your patrol force may be running low on zinc.
Revitalize Formula – The Cleanup Crew
After a crime, every city needs a cleanup crew to clear debris, restore order and keep the environment safe. In your body, that vital role belongs to your liver—and TriVita’s new Revitalize Formula supports it in powerful ways.
With N-acetylcysteine, milk thistle, turmeric, schizandra, artichoke and dandelion, Revitalize Formula helps your liver detoxify the body and boost glutathione, the master antioxidant that protects and renews immune cells. A healthy liver ensures the immune system can keep working without being bogged down by toxins and inflammation.
Why it matters:
- Detoxifies and clears harmful substances from the body, thereby improving immune function
- Replenishes glutathione to recharge immune cells
- Lowers inflammation and supports long-term resilience
If you often feel sluggish, have digestive upset, or struggle with skin or toxin sensitivity, your immune cleanup crew may be overwhelmed and in need of backup.
Why Preparation Matters Now
In August 2025, the CDC’s Center for Forecasting and Outbreak Analytics projected two potential COVID-19 peaks—one in late summer 2025 and another, larger surge in early 2026. They also warned that most hospitalizations and deaths will occur in adults aged 65 and older.
This may sound concerning, but it doesn’t need to cause fear. Instead, it reminds us that preparation is power. By strengthening your immune force now, you can face the season ahead with greater peace and confidence.
The Peace of Readiness

This synergy keeps your immune system ready to protect your “community of health.”
