It's important to consider the safety of the vitamin combination you mentioned during pregnancy, especially at 22 weeks.

This combination includes:

• Calcium Pantothenate (Vitamin B5): Supports energy metabolism and fetal development.
• Cyanocobalamin (Vitamin B12): Essential for nerve function and red blood cell production.
• Nicotinamide (Vitamin B3): Helps with cellular metabolism and skin health.
• Riboflavin (Vitamin B2): Important for energy production and growth.
• Thiamine (Vitamin B1): Supports nervous system function and energy metabolism.
• Pyridoxine (Vitamin B6): Aids in brain development and immune function.

These vitamins are commonly included in prenatal supplements and are generally considered safe when taken as prescribed. However, the specific product you mentioned is categorized as Category C for pregnancy, meaning there is not enough definitive evidence to confirm its safety during pregnancy. This classification suggests caution and the need for medical advice before use.

Because every pregnancy is unique and vitamin needs can vary, it is essential to consult your obstetrician or a maternal-fetal medicine specialist before starting or continuing this supplement. They can provide personalized guidance based on your health status and pregnancy progression.

In summary:

• The vitamins listed are typically safe and beneficial in pregnancy.
• The specific combination lacks sufficient safety data for pregnancy.
• Always consult your obstetrician before taking this medicine during pregnancy.

If you have any concerns or experience unusual symptoms, seek medical advice promptly.
