Agnusides

Ever heard of Chasteberry? Agnusides are the active compounds found within this ancient plant (Vitex agnus-castus). Often referred to as 'Nature's Hormone Balancer,' these phytochemicals are the reason this berry has been used for millennia to support female reproductive health. Unlike synthetic hormones, Agnusides work gently by communicating with your pituitary gland. Think of them as a dimmer switch, helping to naturally regulate the production of key hormones like progesterone and prolactin, bringing your body back into a harmonious rhythm.

Deep Dive

Agnusides function as dopamine agonists. In simple terms, they mimic the neurotransmitter dopamine. Elevated dopamine levels naturally suppress the release of prolactin from the pituitary gland. High prolactin is a common culprit behind irregular ovulation and PMS. By keeping prolactin in check, Agnusides allow progesterone levels to normalize, stabilizing the menstrual cycle and soothing those rollercoaster symptoms.

While Agnusides are highly concentrated in the Berry of the Chasteberry tree, they are not found in standard fruits or vegetables. To get a therapeutic dose, you typically need to consume the berry itself or a concentrated extract.
