At that time the kind of nutritional formulations he envisioned – for the maintenance of well-being and the enhancement of life – simply didn’t exist. The idea of combining many nutrients herbs and nutraceuticals in one formulation though common today was then a rarity. Source Naturals pioneered the concept with Wellness Formula now the industry’s #1 immune support product.
