NF Formulas

  • Supports healthy female hormonal balance.
  • Relieves symptoms of menstruation and menopause.

Spectra 305 is formulated to help balance the female hormonal system. A healthy dosage of vitamin B6 helps normalize nerve impulses, reducing cramping and nervous irritability. Dong quai, known as “female ginseng” in China, is noted for its ability to relax smooth muscle tissue. It, along with cramp bark, also helps ease menstrual cramps. Damiana, an herb originating in Mexico, provides a slight herbal lift to alleviate fatigue experienced during the monthly cycle. Wild yams contain phytoestrogens, which help regulate hormonal fluctuations. Evening primrose oil, with its ability to combat the body’s inflammatory response, reduces the bloating many women experience during the menstrual cycle. Black cohosh is regularly used in Europe to counteract some of the symptoms of menopause.

Suggested Use: Take 1 tablet daily or as directed by your healthcare practitioner.
