We've all been there. Whether it's 30 minutes or a couple hours after you take your nutritional pre-workout supplement. Their's at least one supplement that has forced you to either stop your workout, or has made you run to the bathroom afterwards. Yes, I'm talking about the bubble guts, the soupy poopies, the Hershey squirts or whatever you may call it. Just about every person I've been bravely enough to discuss this topic with in the gym, has had a similar story and can relate.
Everyones body is different. Which means everyone digests foods and nutrition differently, so their's no way of pinpointing what specific pre-workout supplement
will affect your digestive system in a negative way. Their are, however ways of telling which products could potentially cause you to make a B-line to the restroom during your workout.
For someone who suffers from Ulcerative Colitis, like myself, needs to be especially careful about what products enter our digestive system. Their are a few products out there with one main ingredient that I absolutely, 100% stay away from taking too much of.
The number one ingredient I always, always keep an eye out for in any product is Magnesium. Magnesium is the fourth most abundant mineral in the body. It's main functions are to help maintain normal muscle and nerve function, keep heart rhythm steady, support a healthy immune system, and keeps bones strong. But just like anything else, too much of something can cause adverse effects to your body. Don't get me wrong, our bodies need magnesium but you CAN overdo it. The average person over the age of 21 should not consume more than 300-400mg of magnesium per day depending on their size. High levels of magnesium in supplements can promote adverse effects such as diarrhea and abdominal cramping. Ever heard of "Milk of Magnesia", also known as Magnesium Hydroxide? If not, Magnesium Hydroxide is used to treat constipation! Therefore, too much magnesium can cause you to make that ever-so-dreaded run to the bathroom during your workout.
Again, everyone is different which means everyones digestive system works differently. But next time you are at the local drugstore picking out your supplements, or are curious to why you may be having digestive issues when you take a certain product, I urge you to take that extra few seconds, scan the label, and see just how much magnesium the product contains and how much magnesium you could be ingesting in one day.
