I took GNC womens ultra mega vitamins for 2 months. They have 80 mg B vitamin complex, 500 mg calcium, 250 magnesium, 200 mg vitamin c, and other vitamins and minerals at or above the RDA. Gnc vitamins made me irritable, and edgy, and very tired at times. So I discontinued them. I started taking the Centrum, and even though they don't give me a lot of energy, I am more calm. What could have caused the reaction from the GNC vitamins I was taking, and are the Centrum better for me ??
Has anyone had similar experiences.....?
Yes, I can think of lots of reasons! The ingredient list in those (the GNC) vitamins is a mile long. Some having 3000% or more of the RDA of certain items. A lot of stomachs are sensitive to excesses like these.
As for the tiredness, some people sort of feel a "crash" after any green tea (which the GNC vitamins contain).
Also - some people report irritability with excess B vits, which this is.
Yes, I've also heard of the irritability associated with high amts of b vits. Wasn't sure if it was just me, but I definately felt on edge, and became very tired later in the evening, so much so, I had to go bk to Centrum. Thank you, looks like these were a little too much for me.
