Standard Process' Drenamin supplement is a huge energy booster if you've ever suffered from adrenal issues or adrenal fatigue. Immediately after I first began taking this supplement, I felt my energy levels rising. It does still take time to build your adrenals to optimal levels, but this product gives them the nourishment they need from whole food ingredients and you can immediately feel the benefits. These whole ingredients include animal products such as bovine liver, bovine adrenal, bovine bone, porcine stomach, etc. which all serve to give you the nutrients people used to get from eating organ meats and bone broths. I've felt the difference in my body that this supplement makes, so I'm a firm believer in Drenamin. If you've ever had hypo or hyper adrenal problems, this supplement will balance out your adrenals and give you the right kind of energy that you need. Taking this supplement for even one month made me feel better!
