Adherence to vitamin and dietary supplement intake in fertility and pregnancy care: insights into knowledge, information satisfaction, and formulation variability.

Our assessment

This 2026 study surveyed women in Germany who were either seeking fertility treatment or were already pregnant. Researchers used an anonymous online questionnaire with 34 questions to look at how well these women stuck to their vitamin and supplement routines, how satisfied they were with the information from their healthcare providers, and what they knew about key nutrients. The study measured adherence using the MARS-D scale and satisfaction using the SIMS-D scale [2026 study]. Because the full number of participants is not provided in the data, we cannot confirm the sample size, which is a limitation.

How it works

Think of this research as a check-in on real-world habits. It is not testing a specific vitamin, but rather exploring how well women follow supplement advice during a critical health window. The findings suggest that a woman's knowledge of essential micronutrients and her satisfaction with the information she gets from her doctor or clinic strongly influence whether she actually takes her supplements as recommended. This means that clear, satisfying communication from healthcare providers could be just as important as the supplements themselves for supporting fertility and pregnancy health [2026 study].

Safety profile

Data not available. This study focused on adherence and knowledge, not on side effects or adverse events from supplements. No specific side effect data or FDA report counts were provided in the data FDA FAERS ↗.

Our recommendation

If you are planning a pregnancy or are currently pregnant, use this study as a reminder to have an open conversation with your healthcare provider. Ask about which specific vitamins and minerals (like folic acid or iron) are right for you, and make sure you feel confident in the information you receive. Feeling informed and satisfied with your care plan can help you stay consistent with your supplement routine, which is key for both fertility and a healthy pregnancy [2026 study].
