I was a customer of AB for years, using the bone formula, probiotics, and other just general supplements for good health. When my financial situation changed, I had to budget and could not afford certain unnecessary items. But as I got older and had more physical problems, I ended up trying advertised formulas, which weren't really helping and wasted my money. I remembered AB, and ordered Nerve Support. Now instead of taking three or four useless brands, adding up to 6 or 9 caps a day, I'm back to taking just 2 pills a day with much better results. I highly recommend Advanced Bionutritionals for their products and the trust of the company.
