DIM Supplements: A Buying Guide
What Is Diindolylmethane (DIM)?
Diindolylmethane is the natural compound produced in our body after the digression of indole-3 carbinol (found in cruciferous vegetables). This compound has many health benefits because of its cognitive, antioxidant and anti-inflammatory properties. It is also one of the reasons why vegetables such as cauliflower, kale and broccoli are considered a nutritious and essential part of your diet.
Though some additional research is necessary to understand exactly what DIM does for the body, it is still a popular supplement that many people take for health benefits, especially those related to hormone regulation.
DIM isn’t just for casual use. It is used in some medications, for example, those for recurrent respiratory papillomatosis, and according to Dr. Naheed Ali, a medical writer, “some studies have suggested that DIM supplements may have potential health benefits, including a potential protective effect against certain types of cancer.”
Choosing the Right DIM Supplement
To pick the optimal DIM supplement, you should pay close attention to the following factors:
Ingredients
The ingredients that DIM supplements are made from are one of the most crucial factors to consider, especially for vegans and people with allergies. For the best results, opt for a DIM supplement that is non-GMO, soy-free, gluten-free and dairy-free and doesn’t include any artificial flavorings. Don’t forget to check the ingredients list of the product to ensure that you aren’t allergic to any of them.
Dosage
Taking DIM in high amounts can cause adverse side effects such as vomiting, headaches and nausea. This is why you must take the dosage of the supplement into account. While subjective, on average, 100-400 mg of DIM is considered normal for most people. If you’re going to take the supplement for the first time, it’s safer to begin with, a smaller dose. Generally, powdered DIM works well for first-time users since you can easily adjust your dosage as needed, which is trickier to do with pills.
Brand
Your health is not to be messed with, which is why you should only purchase a DIM supplement from a trustworthy brand. Unfortunately, there are manufacturers out there that try to rip people off by selling unhealthy or low-quality supplements made from unsafe ingredients.
To avoid this from happening, make sure that you purchase the supplements from a certified retailer. Additionally, you should also read online reviews of the product to get a better idea about other people’s experiences with it.
What Are the Benefits of Taking DIM Supplements?
DIM supplements offer several health benefits. Some of the major ones include:
Restores hormonal balance
Hormonal imbalance is one of the major health issues that many women face. Hot flashes, mood swings and irregular menstruation cycles are all some of the common side effects of these imbalances. Not only are these imbalances unpleasant, but they can become dangerous if left untreated. For instance, excessive estrogen levels have been linked to cancer cell growth.
DIM supplements help restore this balance by improving good estrogen ratio, reducing androgen and supporting estrogen metabolism.
Helps with inflammation
According to research, there is a correlation between chronic inflammation and the proliferation of cancer cells. Several studies conducted on rodents to determine the effects of DIM on acute and chronic inflammation showed that DIM reduces the production and release of interleukin, nitric oxide and prostaglandins. These findings suggest that DIM may help to regulate inflammatory responses.
Reduces cancer cells
According to research from the National Center for Biotechnology Information, an unhealthy lifestyle can be one of the causes of the development of cancer cells. DIM not only offers natural protection against damaged cells but also fights against free radicals in the body. It also enhances enzyme activity in the liver’s pathway. This helps reduce the risk of cancer cell development in the body.
