Possibly. You decide based on what you observe to be true by your investigation, research, experience, and experiment. Acne or other unwanted body reactions could occur with different vitamins. Judgement plays a role and experimenting with what works for your body would be important. Here are just a few things to consider or factors concerning vitamins. Not all vitamins are equal. There are grades of vitamins depending on the manufacturer, how old it is, how it was derived, etc. Quality can certainly vary. Also, some vitamins or nutrients are 'more alive', not 'dead' chemicals. Quality...not all nutrients or brands are equal even though the bottle's label may say 100mg of Vitamin__. Vitamins are supplements. They do not contain the whole host of nutrients which a person needs, but they can help to supplement different deficiencies within the body. A good diet is always important and most effective. In fact, there are schools of thought which propose that vitamins tax the body's system. Regardless, a good diet is essential. But in this non-organic age where many nutrients are lacking in foodstuffs, along with very, very harmful herbicides on foods (and even coming down again in the rain) or just general environmental toxins, it may be wise to supplement one's diet. However, vitamins are an "in addition to", a supplement. Vitamins or nutrients need to be balanced properly. Too much of one type of vitamin or mineral can "rob" your system of correlating essential nutrients. An example is calcium and magnesium. If one has lots of calcium floating around the body in relation to magnesium, then the magnesium starts to be extracted from other cells or parts of the body. Thus the body tends to be robbed of magnesium (or overdosed with calcium). You can review some other answers of mine about the ratio of magnesium and calcium for more information. Vitamin A can be overdosed causing headaches and other bad effects on an individual. The B-vitamins tend to balance with each other. For example, if a person starts dreaming a lot after taking a handful of vitamins, they are deficient in B1. Taking B1 will put an end to too much dreaming and is a great remedy for little kids having nightmares (probably the sugar treats or stress had burned up the B1 in the system). Some vitamins are water soluable and pass through the system rapidly, like the B vitamins or C. In fact, Vitamin C often is not taken frequently enough in order to combat colds or other sicknesses. Some people recommend taking it every 30 minutes...but of course, the excess will be eliminated and one will know their system is becoming filled with Vitamin C by the loose bowels which follow. At the same time minerals are being washed out of the body with all the Vitamin C cleansing and should be replaced. So, proper proportions or balance is important. Another thing to consider is "what works for your body". Bodies are different from one person to the next whether by genetics, gender, age, exposure to environmental toxins and the body's tolerance levels to these and what has accumulated within the fatty tissues or cells, what toxins are in restimulation, mental outlook, etc. Probably a good rule of thumb, is to note your diet and activities while taking supplements. If one notices odd or adverse reactions, one can try to identify the cause of the adverse reaction by the process of elimination. As an example, if one's diet is stable along with routine activities, but the person notices a general weakness (or other symptom, mental or physical) after taking supplements...then the person can try narrowing it down by eliminating or decreasing the use of a certain supplement. There is something important to note on this line of thought. Just because a body reaction occurs temporarily, does not necessarily mean that it is unhealthy. This can occur with the B vitamin, Niacin, for instance. A flush will turn on when taking it. This is not unhealthy and, in fact, helps to serve in eliminating radiation. By continuing the same small dosage day after day (with other vitamins properly balanced), the flush will eventually disappear and pass. Another instance of this could be in taking carrot oil (carrier, not essential). Acne could turn on, but with continued use of the oil, it will pass. So, one can identify or try to observe what works well for the body (and bodies change with age or lifestyle) keeping in mind that temporary reactions could occur as one's system adjusts. It is the long-term detrimental changes which a person is trying to avoid. Another aspect to look at is the fillers or other added substances that are used in the packaging or preserving of some vitamins. (After all, vitamins are a food substance and need to be preserved.) Some vitamins have toxic residues or solvents or even metals depending upon the manufacturing process or the container. Some people have adverse reactions to some of these added things or the components of the vitamins. Again, this is a type of quality issue. Also, different vitamins are made differently. For instance, most people think of lemons or orange juice when they think of citric acid. A lot of citric acid ( along with many, many products) is manufactured in China. It looks like a very fine white crystaline powder. It is actually manufactured [in brief] by introducing a mold to a sugary substance. A solution is extracted from this and lime is introduced to the solution. (Lime is a strong alkaline substance which has uses in making mortar or cement or plaster, whitewash, tanning leather, treating sewage or acid soils, etc. Lime itself is very caustic and could injure a person just by skin exposure.) After the lime is introduced to the solution and a resulting calcium citrate salt is made, then sulfuric acid (pretty strong stuff) is used to treat that salt and regenerate a citric acid. So, that is citric acid as you now see it in many food stuffs. Components of some vitamins or their processing methods could cause a reaction like acne. There are probably other aspects to look at with vitamins. You are correct in questioning if acne could be caused by vitamins, (or by any other internally digested substance). After all, the largest organ on the human body is the skin. The skin absorbs things from the environment and eliminates different substances from the body, along with performing a whole host of other functions. The skin is very important in eliminating toxins. What is released through the skin could prompt acne.

Not directly. However, nutritional imbalance - an excess or lack of vitamins and minerals in your body - may contribute to the severity of acne. Such imbalances also cause physical stress that, along with psychological stress, may also be a factor. It is also important to eat a balanced diet and to avoid certain types of foods (e.g., those with a high fat content). Moderation and balance in your diet and in the use of supplements is the best approach. Some vitamins are considered beneficial to the skin and may help in ameliorating acne. However, you should use these with due caution. Vitamins A, D, and E are often claimed as being beneficial, but they are fat-soluble vitamins. Increasing their dosage should be managed with care. Overdoses or long-term overconsumption of Vitamin A, in particular, or D may lead to serious health problems.

Call it a coincidence, but ever since I stopped taking a mutivitamin a year ago, I have had few to no blemishes. My skin is generally good. Last weekend I decided I could use a little extra pick-up to do some work around the house. I took a multi-vitamin 3 days in a row……and…..an irritating blemish near my chin by Wednesday.

I have clear skin and I decided to take Women's one a day energy vitamin and broke out with acne all over my face, not knowing that it came from the vitamin I continued taking the one a days. I noticed that my skin was less irritated in the evenings and more irritated and red in the mornings after taking the vitamin so I discontinued the use of the vitamin and my face started to clear up instantly. My conclusion is that the vitamins caused my out break of acne...

Monavie (a type of supplement) caused my face to erupt in rosacea type acne...uggh i have never had acne. So i am certain supplements can cause acne.
