Some research has found a link between heavy menstrual bleeding and soy formula feeding in infancy.
Other research suggests that menstruating people who were fed soy formula as infants may be more likely to experience more painful periods.

Soy-protein formula contains a relatively high level of aluminum compared to breast milk and cow's milk-based formula.
This exposure is not thought to be a problem for full-term infants but may lead to reduced bone mineralization in preterm babies, especially those with impaired renal function or renal failure.
Healthy, full-term infants are not at substantial risk of aluminum exposure from soy formula. Soy formula and soy milk are entirely different products.
