Little-Known Liquid Multivitamin Side-Effects To Avoid

Many people may choose to use a liquid multivitamin. Some people have problems swallowing pills and taking a multivitamin in a liquid form (such as the brand Centrum) helps them to avoid these problems. Some people also believe that liquid multivitamins are more potent, and are more readily used by the body, than their pill counterparts. Yet, there are some side effects to liquid multivitamins that you should be aware of and try to avoid.

Liquid Multivitamins May Upset the Stomach

Some people have a more sensitive stomach than others. This can mean that a liquid multivitamin may cause stomach upset, especially if taken alone. A way to solve this problem is to add your liquid multivitamin to your drink, such as juice or water. This may also solve any taste problems that may have with swallowing the multivitamin by itself.

A Liquid Multivitamin Overdose

A multivitamin (including the liquid multivitamin) is a vitamin that contains a combination of the common vitamins and minerals we need per day. Each comes with a recommended dosage, and it is advisable to take these dosages at the same time every day. It is also advisable not overdo your vitamin intake.

An overdose of vitamins or minerals can be harmful to your body. You should especially pay close attention to the recommended amounts of calcium, iron, magnesium, potassium, and zinc you get a day. Too much of these can cause a number of health conditions including: 

  • teeth staining
  • increase urination
  • stomach bleeding
  • muscle weakness
  • uneven heart rate

Many people may think it is wise to increase their amounts of Vitamin C during the cold season to help protect their immune system. You should not increase this amount to go over the recommended daily allowance. If you do, side effects can include: 

  • a change in one’s menstrual cycle
  • diarrhea
  • stomach cramping
  • flatulence
  • nausea
  • the development of kidney stones

Side Effects Of Liquid Multivitamins Containing Folic Acid

There can be side effects of each and every vitamin and or mineral that is combined into a liquid multivitamin. For this reason, it may be hard to pinpoint the exact origin of any side effects that may occur. For example, the mineral folic acid, which is needed for red cell production and a baby’s early stages of development, can cause severe side effects such as:

  • rash
  • hives
  • difficulty breathing and tightness in chest
  • swelling of face, mouth, tongue, and lips  
  • nausea
  • diarrhea
  • stomach distress

Allergic Reactions

Some people may also be allergic to liquid multivitamins, and an allergic reaction can cause:

  • itchiness
  • redness
  • rash and hives.

If you do not believe you will experience any of the above side effects, and you have problems swallowing pills, a liquid multivitamin may be the choice for you. Multivitamins are a great way to ensure you get the right amount of the vitamins and minerals needed each day to maintain good health.

    Interesting, it’s amazing how many side affects can occur. I think people don’t realize it simply because they don’t understand an excess in anything, even vitamins can cause such problems. This is actually very informative.

    I just ran across your question and thought i would give you a little advice. I am no expert when it comes to vitamins but i have been researching alot about them so that i know what is real or fake. I dont want to benefit the company by buying their product, i want to benefit my body and my life. Few people do not know that most of the ingredients in vitamins today are synthetic (not real). If you research this you would be amazed at what you will discover. For instance, when it comes to Vitamin E, if the label reads (USP) anywhere, or if the ingredients is listed as DL-Alpha, then it is synthetic. If there is no ingredients listed for that particular vitamin, you can assume it is synthetic. That is only one small example.

    The human body does not absorb synthetic ingredients. As a matter of fact, It builds up in your fat tissues and becomes toxic. You are actually causing yourself more harm than good by taking vitamins that are synthetic. In the long run, these toxins build up in your tissues and destroy your kidney. I cannot stress enough how important it is for you to read the ingredients . The bottle can read “100% Natural or “100% Organic” and still be synthetic. Yes its true and worth repeating. It can, and more than likely is synthetic even if they state it is 100% Natural or Organic. People need to be informed. These companies arent out to make you healthier, but to make their pockets fatter.

    If you go to this link you can see easily how to read labels and tell which vitamins are actually the real thing or just a waste of your hard earned money and time. Just copy and paste. The more i research the more amazed i become. I am still in the process of finding that true vitamin that i know for certain is going to benefit me and my health. Good luck to all of you who read this and please research. Its well worth your time and never forget, knowledge is power.

    wow ! amazing , it’s great how many side affects can occur. I think people don’t realize it simply because they don’t understand an excess in anything, even vitamins can cause such problems. This is actually very informative.

    Folic acid is not a mineral. In addition, the side effects mentioned here are what is possible with huge doses over periods of time. Average healthy person taking any given “label recommended” amounts of one product at a time will NOT suffer these “side effects.” Most of us are in far more danger of not getting enough nutrients vs. getting too many.
