EARLY WARNING SIGNS OF LOW T
After the age of 30, testosterone levels begin to drop about 1% to 3% each year.* That’s a 10% to 30% drop in ten years. Among men in midlife—those over 45—at least one-third experience testosterone insufficiency.** If you’re feeling depleted, it’s helpful to know the signs of low Testosterone:
Low energy
Insomnia
Loss of muscle mass
Lower bone density
Joint pain
Weight gain
Decreased sexual performance
Irritability or anxiety
Brain fog.
Checking Testosterone is easily done with a blood test.
WHY IT MATTERS
If low T turns out to be an issue, you’ll want to bring your levels back into balance. Your hormones protect you, and when those levels drop, the risk of more drastic conditions increases:
Clogged blood vessels
Diabetes
Cardiovascular disease
Osteoporosis
Premature dementia
Most men are surprised to learn that Testosterone is protective against every one of these potentially fatal disorders, including diabetes, heart disease, cancer, and dementia.
SUPPORTING TESTOSTERONE WITH BOTANICALS AND MINERALS
Today, we can also increase Testosterone with oral supplements because we have more research available than we did 15 years ago. This approach is termed evidence-based medicine, because we can use the research to guide us.
Here, we’ll provide the research used to formulate the testosterone-booster, SupporT.
Brandeis MD
SupporT is a testosterone-boosting supplement formulated by Dr. Judson Brandeis, a board-certified urologist, surgeon, and principal investigator for five clinical trials on men’s health. This supplement contains ingredients confirmed in the research to help promote Testosterone and sexual function.
DHEA Dehydroepiandrosterone is a hormone produced by the adrenal glands that our bodies convert into Testosterone, estrogen, and cortisol. Unfortunately, like Testosterone, DHEA levels start to decrease at about 30. DHEA is available in supplement form and has been studied for the potential to increase testosterone levels, particularly in individuals with low baseline levels. Replenishing DHEA has the potential to support healthier testosterone levels and has been shown to boost total Testosterone levels by 14% in men presenting with low Testosterone.
DIM is derived from cruciferous vegetables like broccoli and cauliflower. Since DHEA is a precursor to both Testosterone and estrogen, the DIM is included in this formula to reduce conversion to estrogen, supporting higher Testosterone levels. Of note, DIM has also been found to reduce the risk of prostate cancer.

Indian ginseng (Ashwagandha) is a plant-based botanical used worldwide in supplements and herbal remedies. This adaptogenic herb has been studied for its potential to reduce stress and improve hormone balance, including testosterone levels. Studies show that ashwagandha (“like a horse”) can help boost Testosterone, enhance muscle development, and reduce body fat.
Brandeis MD
Tongkat Ali, also known as Eurycoma longifolia, is a plant native to Southeast Asia and has been traditionally used for various purposes, including as an herbal remedy for boosting testosterone levels. Some studies suggest that Tongkat Ali may have a potential impact on testosterone levels. In a study published in the Journal of the International Society of Sports Nutrition in 2013, researchers gave Tongkat Ali extract to male subjects for four weeks. They reported an increase in testosterone levels in the group that received the Tongkat Ali extract compared to the placebo group. Another study published in the Journal of Ethnopharmacology in 2014 found that Tongkat Ali supplementation significantly increased testosterone levels in men with low Testosterone. This study suggested that Tongkat Ali might have potential as a natural remedy for addressing testosterone deficiency.
Brandeis MD
Magnesiumand Zinc are minerals essential for health that are often lower in today’s typical diet. Magnesium plays a vital role in muscle function, and Zinc, a trace mineral, is crucial to cell function. Insufficient amounts of either of these elements can reduce testosterone levels in men. Ensuring an adequate intake of these minerals through diet or supplements has been found to support healthy testosterone levels, particularly in individuals with mineral deficiencies.
These nutrients and botanicals are designed to improve your overall wellbeing, while maximizing support for healthy levels of Testosterone.
LOOKING AT THE RESEARCH OF WHAT WORKS AND DOES NOT WORK TO BOOST TESTOSTERONE LEVELS IN MEN
DHEA
Dehydroepiandrosterone (DHEA) is a hormone produced by the adrenal glands that is broken down to make sex hormones, including Testosterone. Several studies have explored the relationship between DHEA supplementation and testosterone levels with key findings:
Dehydroepiandrosterone Supplementation and Hormonal Responses to Resistance Exercise (Journal of Applied Physiology, 2006):
This study investigated the effects of DHEA supplementation on hormonal responses to resistance exercise in young men. The results showed that DHEA supplementation led to a significant increase in serum testosterone levels compared to a placebo group.
Dehydroepiandrosterone Supplementation and Cognitive Functioning in Older Adults (Journal of the American Geriatrics Society, 2003):
In this study, DHEA supplementation in older adults was evaluated for its effects on cognitive function. While the primary outcomes were related to cognitive function, the study reported an increase in serum testosterone levels in the DHEA group.
It’s important to note that the effects of DHEA supplementation on testosterone levels can vary among individuals, and that the responses may be influenced by factors such as age, sex, and underlying health conditions.
DHEA supplementation is generally considered safe when used at appropriate dosages, but it may have potential interactions with medications. Therefore, it’s crucial to consult with a healthcare provider before considering DHEA supplementation, especially if you have a specific health condition that may be affected by hormonal changes.
DIM
Diindolylmethane (DIM) is often studied for its potential to support hormone balance, particularly by promoting the conversion of estrogen into its less potent forms and by reducing the conversion of Testosterone into estrogen. Studies and findings related to DIM’s ability to inhibit the conversion of Testosterone into estrogen:
Diindolylmethane Inhibits Estrogen-Induced Expression of Fibulin-1C and Other Genes in Human Endometrial Cells (Endocrinology, 2008):
This study investigated the effects of DIM on estrogen-induced gene expression in human endometrial cells. DIM was found to inhibit estrogen-induced gene expression, including the inhibition of the estrogen receptor (ER)-mediated pathway. This suggests that DIM may help reduce the effects of estrogen, including the conversion of Testosterone to estrogen.
Indian Ginseng (Ashwagandha)
Ashwagandha (Withania somnifera) is an adaptogenic herb traditionally used in Ayurvedic medicine, that has gained attention for its potential to influence hormonal health. There have been several studies exploring the effects of ashwagandha on testosterone levels:
