Additionally, many of these supplements have other components whose safety for breastfeeding parents and their infants may not be well studied or understood.
If you're considering taking pre-workout supplements, it's best to consult with your healthcare provider. They can help you understand the potential risks and benefits based on your specific circumstances, the particular supplement you're thinking about and the latest research.
