A new study from the UK Women’s Cohort Study suggests that certain dietary supplements may be linked to a later onset of menopause, offering potential insights into reproductive aging. The study analyzed data from 3,566 women, tracking their supplement use, diet, and lifestyle habits in their 20s, 30s, and 40s.
Researchers found that women who regularly used fish oil, B-complex vitamins, antioxidant mixtures, and vitamin C tended to experience menopause later. Fish oil showed the strongest link, with users having a reduced likelihood of early menopause, which is defined as occurring before age 45. Early menopause is associated with higher risks of osteoporosis, heart disease, type 2 diabetes, and mood changes. A later menopause, after age 55, can slightly increase the risk of hormone-related cancers.
The study’s authors suggest that these nutrients may help slow ovarian aging by reducing oxidative stress and inflammation, modulating reproductive hormones like follicle-stimulating hormone (FSH) and estradiol, and supporting mitochondrial function and DNA repair. Ovarian aging refers to the gradual loss of egg quantity and quality over time, which eventually leads to menopause.
Study Details and Limitations
The research examined lifestyle factors leading up to menopause, including behaviors in the women’s 20s, 30s, and 40s. It tracked supplement use such as fish oil, B vitamins, vitamin C, and antioxidants, then analyzed how these patterns were associated with the age at natural menopause, meaning menopause not caused by surgery or medical treatment.
The study does not prove cause and effect, but it is one of the first large-scale analyses to show that specific supplements and lifestyle habits may influence the timing of menopause. The findings highlight the potential role of nutrition in supporting reproductive health and overall longevity.
Nearly 95 percent of Americans do not get enough omega-3s through diet alone, according to the study. Omega-3 supplements, particularly those providing at least 1,000 milligrams of combined EPA and DHA per serving, are recommended for supporting hormone and reproductive health. B vitamins, vitamin C, and other antioxidants are also suggested for daily support, and a multivitamin can provide these nutrients at clinically effective doses.
Menopause typically occurs around age 51, but the timing varies. Because women spend a significant portion of their lives postmenopause, understanding what influences this transition is important for long-term health. The study adds to a growing body of research on how diet and lifestyle may affect reproductive aging.
