Havasu Nutrition's Elderberry Gummies contains 100 mg Sambucus Nigra extract, 120 mg of Vitamin C, and 7 Mg of Zinc. This formulation lacks two of the most powerful ingredients available: Echinacea purpurea extract and Propolis extract. Without these two, this supplement may not be as effective at supporting immune health. Havasu Nutrition's clear and natural formula is free from fillers and their 60-day return policy means they earned a spot as our Number 3 Elderberry Gummy.
