Research over the past decade has expanded the importance of Vitamin D in human nutrition. Vibrant Health believes that if a vitamin D3 supplement MUST be made mostly of excipients, then those excipients should be the cleanest, heatlhiest ones available. That is why we developed the Organitab, a tablet made almost entirely of certified organic ingredients. Each Vibrant Health Vitamin D3 product is more than 97% certified organic. That is the value of our Organitabs.
