Dim is the shortened name used to refer to Di-Indoly Methane, a type of plant nutrient. Dim supplementation has been used as a natural way to treat symptoms of menopause. It is found in cruciferous vegetables and has been said to help a woman achieve hormonal balance. If you plan to use a Dim supplement, you will want to review the side effects.


Prior to taking Dim to help treat your symptoms of menopause, you should talk to your doctor. He can also provide recommendations on the amount of the supplement you should take everyday. Dim is typically sold in 100mg tablets with manufacturers recommending one to four pills consumed daily as a dietary supplement. You can find Dim supplements at vitamin stores or online at retailers. Popular brands include Source Naturals, Douglas Labs and Nature's Way.

Side Effects

Very few side effects have been reported with Dim supplements, but some individuals have developed headaches. Other potential side effects include upset stomach and gas. Some manufacturers have recommended taking half the normal dosage amount to see if this resolves the side effects. Taking more than the recommended amount will increase your chances of developing side effects.

Allergic Reactions

The most concerning potential side effect is that a person will have an allergic reaction to the Dim supplement. Stop taking Dim and contact your doctor immediately if you develop hives, facial swelling, difficulty breathing, chest tightness and dizziness. These symptoms could develop within minutes or hours of taking the product.


As stated, in most cases, Dim has not been shown to cause side effects. However, many people wrongly assume that since Dim is derived from cruciferous vegetables, it will not cause side effects. This is not accurate since a Dim supplement will contain a higher amount of the substance than vegetables. Also, you are taking Dim without the other components that make up the vegetables. These components will aid the body in digesting the Dim supplement.


Don't assume you will not have any side effects since many manufacturers will often advertise that their Dim supplement has no known side effects. This could be the case because not a significant number of clinical trials have been performed for the product.
