I learned the value of hormones when my mother went through menopause. I learned the importance of bio-identical hormones in an organic base from my father and partner, Daved Rosensweet MD. Hormones never stop mattering... but our bodies' ability to produce them diminishes with time! If you eat organic then you know the importance of it. Hormones are almost universally delivered in a base that contains heavy solvents such as propylene glycol. They don't have to be! Ours don't and they're 100% organic.
