The secret immunity arsenal your doctor isn’t telling you about. Vitamin C isn’t just hype. It powers up white blood cells to fight infections and shortens flu duration by a full day. Vitamin D is the real MVP, though. Studies show people with low levels get sick 40% more often. Don’t sleep on vitamin A either. It strengthens the barriers in your lungs and gut where viruses first attack. Zinc is crucial, too, reducing flu symptoms by 50% when taken within 24 hours. And B6, it creates antibodies that remember how to fight specific viruses. Stack these five immunity heroes daily, especially during flu season. Your body will recover faster and fight harder against whatever comes your way.
