Is it acceptable for 18 year old girls take wheat gr vitamins?

I'm about 5'3 110 pounds. My mom takes one a day and she says it helps her digestive system and she almost feels up and about instead of dull and sleepy from the foods that she mixes. I have mild ulcers from time to time (hereditary thing), and my stomach does not take most foods seriously.. Will the wheat gr pills have any benefit to me with the info i provided? Just making sure it's safe for a young girl like me to take. Thanks in advance.
