What makes this unsafe for pregnancy?

[chelsee0806]

I take this preworkout called cardio igniter. It is my holy grail. I planning on becoming pregnant in about 3 months and still want to workout. I'm pretty sure I wont be able to take this anymore but I was wondering if you could tell me what ingredients in it make it unsafe to take while pregnant? I have listed them below

I am not sure about all of the other ingredients, but the one for me that stands out it caffeine anhydrous - this means that there is no or little water content in the caffeine which makes it more potent than normal caffeine and its recommended to limit caffeine intake during pregnancy anyway.

I've also read to limit the amount of herbal teas/intake as all of the side effects have not necessarily been tested. With that in mind the mention of a proprietary blend causes me to wonder what levels of herbal ingredients are included... It's likely that the amounts or combinations haven't been sufficiently tested and deemed to be safe during pregnancy.

If in doubt, I say don't! I'd personally opt for the safe side of caution and workout without it if it was me.
