What is The Best DIM Supplement in 2017?

There’s a lot of excitement surrounding DIM supplements due to their potential anti-cancer properties. As more scientific studies are done, it’s becoming clear that there are numerous benefits associated with DIM that make it well worth looking into. Today, we are going to talk about some of the best DIM supplements on the market right now.

What is Diindolylmethane?

Diindolylmethane, often known as DIM, is a powerful plant-based chemical (phytochemical) that can be found in many cruciferous veggies. DIM works to create a healthy balance of testosterone and estrogen in your body.

DIM acts as an aromatase inhibitor. Aromatase inhibitors block the enzyme aromatase, which converts androgens into estrogen. In turn, this limits the amount of estrogen available to stimulate the growth of hormone-receptor-positive cancer cells. (source)

Many scientific studies are currently being done to understand the effects of foods containing DIM in the treatment of cancer. (source)

Advantages of Adding DIM to Your Daily Routine

Whether you are a man or a woman, taking DIM on a daily basis can have an advantageous effect on your overall well-being. Although typically estrogen and testosterone are considered gender specific, they are present in both men and women.

Besides putting yourself at a higher risk for cancer, having your hormones off whack can be detrimental to your health in many other ways.

Women who are in the menopausal or pre-menopausal phases can benefit from more balanced hormones. (source) You’ll notice a decrease in symptoms associated with menopause such as hot flashes, night sweats, irritability and more.

Men in their starting the second stage of life tend to have higher levels of estrogen than when they were younger. Too much estrogen in men can cause symptoms like erectile dysfunction, fertility problems, and even cardiovascular problems. (source)

DIM can help people of all ages restore normal formation of estrogen. Benefits to using DIM supplements on a regular basis include reduced acne, mood enhancers, and increased energy.

Why Choose a DIM Supplement?

You may have heard that foods such as broccoli, arugula, and bok choy contain the natural estrogen blocker DIM. (source) However, to get enough DIM to actually make a difference, you’d need to consume a whopping 2 pounds of broccoli a day. (source)

Hormones and Headaches

Dips or changes in your hormonal balance can create unwanted side effects. (source) Hormone-related headaches are common over the first several days of taking DIM supplements while your body is getting used to its new routine.

Over the counter pain medication can assist you the first few days. If you continue to experience headaches or migraines after the first few days, consider lowering your dosage or talk to your doctor.

What to Look For in a DIM Supplement

DIM supplementation is fairly basic. Most brands don’t include many additives or extra ingredients. In some cases, bioperine, which is a piperine composition derived from black pepper extract, is added to increase absorption. However, more extensive research is necessary to prove whether or not bioperine is effective in this regard.

Some brands will also include vitamin E, which is also used to increase bioavailability. Some studies have found a connection between vitamin E and increased bioavailability. (source)

Recommended Dosage

Most DIM supplements come in capsules ranging between 100-200mg. Some “extra strength” DIM supplements exceed 200 mg. Most suppliers recommend taking between 100 and 200 mg daily.
