Does vitamin B3 intake impact miscarriage rates?

Breakthrough research claiming that the supplementation of vitamin B3 in pregnant women could prevent miscarriages and birth defects was released from the Victor Chang Institute this week. The study was well constructed and the results have been very promising, however, the research is yet to be proven to be beneficial for humans.

The recommended daily allowance of Vitamin B3 or niacin is between 17-18mg/day for women who are pregnant, planning to be pregnant or breastfeeding. It is found in means, green vegetables and legumes as well as Vegemite.

If taking antenatal supplements, check carefully to ensure it covers the recommended daily needs if you are not receiving it from the foods in your diet.

Remember the famous saying in medicine “the difference between a medicine and a poison is the dose”. Therefore, the maximum recommended upper oral intake of niacin (B3) is 35mg/day.

Although the studies have been successfully completed in mice, human trials are now expected to be conducted over the next couple of years. The aim of the human trails will be to find a test that will identify women at risk and to provide a safe dosage of niacin required.

FAQs about improving natural fertility

Will stress affect my ability to get pregnant?

Yes, chronic stress can impact fertility by disrupting hormonal balance and ovulation patterns. Managing stress through relaxation techniques, regular exercise, adequate sleep, and mindfulness practices may help optimise your chances of conception. Consider speaking with a counsellor if stress feels overwhelming.

How does my partner's health affect our fertility?

Sperm health accounts for about 40% of conception challenges. Your partner can improve sperm health by maintaining a healthy weight, avoiding excessive heat exposure (hot tubs, saunas, tight clothing), limiting alcohol, quitting smoking, managing stress, and taking a multivitamin with antioxidants. Sperm takes about 3 months to develop, so lifestyle changes need time to show results.

When during my cycle am I most fertile?

Your fertile window typically spans 5-6 days, ending on ovulation day. For a regular 28-day cycle, this usually falls between days 10-15, with peak fertility 1-2 days before ovulation. Track your cycle using ovulation predictor kits, basal body temperature, or cervical mucus changes to identify your unique pattern. Having intercourse every 1-2 days during this window optimises your chances.
