The Science Backing The Composition Of The Best Estrogen Blockers For Men
Not all estrogen blockers are made to ensure the best quality and safety. The market is flooded with products claiming to be the best, but it’s essential to understand the science behind their composition.
Thus, in this section, we shall explore scientific evidence backing the composition of the best estrogen blockers for men so that you can make an educated choice for your health and well-being.
Alpha Lipoic Acid (ALA)
Alpha lipoic acid is a powerful antioxidant that plays a vital role in cell protection and overall health. ALA helps prevent oxidative stress and cell damage by neutralizing harmful free radicals. In the context of estrogen blockers, ALA’s antioxidant properties are particularly significant.
By including alpha lipoic acid in estrogen blockers, the antioxidant effects of ALA can help counteract the oxidative stress that may occur due to estrogen inhibition.
Moreover, this ingredient has also been studied for its role in glucose regulation and insulin sensitivity. It has been found to enhance glucose uptake in cells and improve insulin signaling. This can be particularly beneficial for women with insulin resistance or conditions such as polycystic ovary syndrome (PCOS), often associated with hormonal imbalances.
DHEA
Chemically, DHEA is a steroid hormone consisting of a carbon chain with various functional groups attached. Its chemical formula is C19H28O2, classified as an androgen, meaning it has masculinizing effects.
DHEA’s capacity to impede estrogen production is an essential function in males. A study by researchers at the University of California, San Diego, provides further evidence of DHEA’s ability to block estrogen production and enhance male health. The study involved a group of middle-aged men who were administered DHEA supplements for six months.
The study results showed that DHEA supplementation significantly increased testosterone levels and decreased estrogen levels in the participants.
Chaste Tree Extract
The primary active ingredient in the chaste tree is vitexin, which naturally stimulates the pituitary gland to control hormone production better. Through this process, vitexin can help regulate testosterone and estrogen levels throughout the body, improving libido and other essential aspects of male sexual health.
While many other components in chaste trees have beneficial properties, such as improving fertility rates, vitexin remains one of its most potent components, explicitly relating to male sexual health problems such as low libido.
When appropriately used, Vitexin can help improve symptoms associated with low testosterone levels, such as absence/reduction in muscle build-up and libido issues, along with helping to reduce estrogen levels.
DIM
DIM is a compound derived from plant-based foods belonging to the compound group known as indoles. It was first discovered in 1940 in cabbage juice; however, its medicinal properties weren’t recognized until much later.
Its chemical composition consists of two compounds: 3,3′-Diindolylmethane (DIM) and 4-Methylsulfinylbutyl Formaldehyde (MSB). DIM and MSB are essential for the compound’s absorption into the body.
Studies have also shown that DIM stimulates apoptosis – the death of cells – which can help heal cells impacted by inflammation or oxidative stress in organs critical for supporting overall male health.
Swedish Flower Pollen
Swedish Flower Pollen is made up of dried flowering plants that are located in Sweden – predominantly varieties of Lilium spp., Orchis spp., Delphinium spp., Vaccinium spp., Huperzia serrata, Campanula spp., Solidago virgaurea, Mentha spp., etc. The bright yellow powder these flowering plants produce makes up Swedish flower pollen.
The active ingredient found in Swedish flower pollen that provides a variety of health benefits is called prostaglandins (PGE-1) which have multiple physiological activities throughout the body, including enhancing male sexual performance, giving antioxidant properties that protect cells from damage caused by free radicals, supporting prostate health and neutralize toxins within the body.
Prostaglandin synthesis requires enzymes such as cyclooxygenase (COX). Without these enzymes taking place, there can be an increase in estrogen production, leading to erectile dysfunction.
Chromium
Chromium has been studied as an advantage when taken along with estrogen blockers for men because it can reduce circulating levels of sex hormone-binding globulin (SHBG). It also helps prevent them from entering circulation and influencing physical characteristics commonly associated with feminizing hormones, such as a rounded hip shape.
By inhibiting SHBG production and acting alongside aromatase inhibitors such as exemestane or letrozole, which inhibit estrogen synthesis or block specific receptors, respectively, chromium-based supplements have shown a potential ability to reduce the side effects such as gynecomastia that occur as a result of elevated estradiol levels due to an imbalance between male and female sex hormones.
