Hormonal Balance and Fertility
The hormonal cycle.
The menstrual cycle is regulated by a careful sequence of reproductive hormones. FSH, LH, oestrogen, progesterone. Released by the pituitary gland and the ovaries in coordination. When this sequence works smoothly, ovulation happens reliably and the cycle stays consistent.
When something disrupts the sequence (stress, thyroid dysfunction, PCOS, perimenopause, nutritional deficiencies), cycles can become irregular and ovulation patterns can shift.
Nutrients with GB Authorised Health Claims for hormonal function
- Vitamin B6. Contributes to the regulation of hormonal activity.
- Pantothenic acid (B5). Contributes to normal synthesis and metabolism of steroid hormones, vitamin D, and some neurotransmitters.
- Iodine. Contributes to normal thyroid function and to normal production of thyroid hormones.
- Selenium. Contributes to normal thyroid function.
- Zinc. Contributes to normal fertility and reproduction.
Thyroid and fertility
The thyroid sits upstream of the reproductive system. Sub-optimal thyroid function, even within "normal" lab ranges, can affect ovulation and cycle regularity. Iodine and selenium both support thyroid function and are present in BioMirco Fertility Advance and Fertility Focus at considered doses.
PCOS and fertility nutrition
Polycystic ovary syndrome (PCOS) is one of the most common reasons for cycle irregularity in women under 40. PCOS responds to a combination of dietary changes, weight management, exercise, and sometimes clinical intervention. Inositol is often recommended specifically for PCOS, though it is not currently in our formulas. If you have a PCOS diagnosis, work with a fertility nutritionist or GP who can build a stack tailored to you.
