I’ve recommended spirulina to patients who want to feel younger for years — but not all spirulina is created equal. That’s why I chose Kona Spirulina, grown in Hawaii with natural sunlight and lava-filtered water. It’s one of the purest, most nutrient-packed foods on Earth. I consider it an easy way to help protect your body from oxidative stress and keep your immune system resilient.†* – Dr. Gundry
