Female Hormone Panel – Rhythm Plus

Female Hormone Panel – Rhythm Plus

Rhythm Plus is a comprehensive assessment of the female hormones oestradiol, progesterone and testosterone spanning a full cycle period. Imbalances revealed in this profile can help illuminate root causes of disorders such as premenstrual syndrome (PMS), infertility and menstrual irregularities.

Balance is the key. Research has long shown that fluctuating levels of oestogen, progesterone and testosterone play a major role in a woman’s overall health, affecting

  • Menstrual cycle
  • Appetite level
  • Mood swings
  • Sex drive
  • Sleep patterns

As well as measuring the hormones oestrogen, progesterone and testosterone, Rhythm Plus also measures melatonin and the adrenal hormones cortisol and DHEA. It’s designed to show these are influenced by the sex hormones and vice versa.

The hormone melatonin is the major modulator of annual and circadian biorhythms in the body. Abnormalities have been closely linked to a variety of behavioural changes and mood disorders including: female hormone disturbance, insomnia, sleep-wake problems, mood disturbance, increased risk of cardiovascular disease, immune dysfunction, inhibition of ovulation and low body temperature.
