I can’t say enough about Symplex F. I’m a perimenopausal woman, who also only has half my thyroid. As you can imagine, the menopause journey has been tough. My chiropractor first introduced me to these & they’re a godsend. It has helped lessen my symptoms, lightened my period (which was very heavy) & has overall contributed to my general wellness. When I run out, my body can tell. This, coupled with Ovex, is a huge help to my body without going on HRT. I’m a big consumer of Standard Process products; they take the purity of their supplements very seriously, & this is one I can’t be without. I highly recommend!
