 My multiple B complex, you name it, I was taking it. My average cost per week was $150. At $7,500 a year, I'm spending on vitamins. You have to have something whole like this product is. And I'm telling you, vitamins, they're crazy expensive. But this product, I stand by this product. I stand by this 100%. You probably got the best supplement on the market. I'm always on the road driving, and I take care of people's dogs. I do feel a difference.
