14 reports from women who tried Vitex
I started Vitex after dealing with thinning hair and dry skin for months. By week 2 I noticed I noticed a subtle improvement. At 12 weeks, the difference was remarkable. Still taking it and plan to continue.
I've been using Vitex for about 8 weeks now for skin dryness and itching. things started to shift slightly around week 4. most of my symptoms had improved considerably. It's been a real game-changer for me.
Vitex has been a genuine turning point for my hormonal acne. I noticed the frequency of symptoms reduced fairly quickly. the symptoms were about 70% better over the following weeks. I'm glad I tried it.
Vitex has been surprisingly effective for my collagen loss and wrinkles. I noticed the worst of the symptoms eased fairly quickly. the difference was remarkable over the following weeks. Still taking it and plan to continue.
I gave Vitex a fair trial for my hair loss and brittle nails. Some improvement in hot flashes reduced a bit but the hot flashes continued persisted. It might work for others but was modest for me.
Research context compiled from published sources
Binds to dopamine D2 receptors in the pituitary gland, suppressing prolactin secretion. Reduced prolactin levels allow normalisation of the luteinising hormone (LH) pulse and improvement of the corpus luteum, supporting progesterone production in the second half of the cycle. May also have mild opioid receptor activity.
