Honestly, with my sleep deprivation, I need all the energy supplements in the world! But joking aside, please don't take L-carnitine or any supplement without asking your gynac. Pregnancy is not the time to experiment with bodybuilding or fat-burning pills!
Beta, why do you want to take these synthetic powder-tablet things during pregnancy? If you need strength and energy, eat a handful of soaked almonds, dates, or drink fresh coconut water daily. Keep your diet natural and ask your doctor before taking any such chemicals.
I also panicked when I saw L-carnitine listed in some multivitamin ingredients early in my pregnancy. But my doctor reassured me that small amounts are fine, though high-dose supplements should be avoided. Just check with your gynac to be absolutely sure!
There isn't enough clear research on whether high-dose L-carnitine supplements are safe during pregnancy. Please don't take any such supplements on your own. Always consult your gynac before adding anything new to your routine.
It is always better to be safe and avoid supplements like L-carnitine during these nine months. Just focus on a healthy, balanced home-cooked diet. Do speak to your doctor if you feel you have low energy.
I had a C-section and learned that keeping our bodies safe during pregnancy is the most important thing. I would strongly advise against taking L-carnitine supplements unless your doctor has specifically prescribed it for a deficiency. Just stick to what your OB-GYN recommends.
