Estrosense is not Lorna's product. Now that Lorna has started her own company she has her own line known as the Smart line. Lorna has decided not to put milk thistle in her Estrosmart due to research regarding breast cancer and milk thistle. EstroSMART (4 a day) is what you should be taking. It will help with both the cysts and heavy periods. Estrosmart Plus is something Lorna recommends more for fertility, however if you find Estrosmart is not helping after a few cycles you can try the Plus in conjunction. Lorna does not usually recommend more than two Estrosmart Plus a day but you can mix it with Estrosmart, for example, two of each a day.
How are your iron levels? Low iron and heavy periods are a vicious cycle as low iron causes heavier periods.
I am attaching a link to a similar question. Please look as Lorna makes recommendations. I am also attaching a link to a Lorna's free book An A-Z Woman's Guide to Vibrant Health.
