2-OH / 4-OH-E1 Balance

Urine
check icon Optimal Result: 5.4 - 12.62 Ratio.

The 2-OH / 4-OH-E1 Balance refers to the balance between two different forms of estrogen metabolites in the body, specifically 2-hydroxyestrone (2-OH) and 4-hydroxyestrone (4-OH-E1). Estrogen is a hormone that plays a crucial role in various bodily functions, including reproductive health and bone density. When estrogen is metabolized or broken down in the body, it forms different metabolites, and the balance between these metabolites can provide important insights into overall health.

The 2-OH form is often considered less harmful, with potential protective effects against certain health issues, while the 4-OH-E1 form is associated with increased risk for conditions like cancer. Therefore, analyzing the ratio of these two metabolites can help assess estrogen metabolism and provide valuable information for optimizing health and preventing potential risks.

Important Note: If Estrogen metabolite levels are very low, the reproducibility of the test is not as ideal, so calculated ratios (for the methylation-activity index and phase I estrogen metabolism ratios) are more approximate, less certain, and may not be reported.

What does it mean if your 2-OH / 4-OH-E1 Balance result is too high?

A high 2-OH / 4-OH-E1 ratio indicates that your body is favoring the 2-hydroxyestrone (2-OH) pathway over the 4-hydroxyestrone (4-OH) pathway for estrogen metabolism. This is generally considered a more favorable outcome as the 2-OH pathway is associated with anti-cancer properties and can block the action of stronger estrogens that may be carcinogenic.

Important Note: If Estrogen metabolite levels are very low, the reproducibility of the test is not as ideal, so calculated ratios (for the methylation-activity index and phase I estrogen metabolism ratios) are more approximate, less certain, and may not be reported.

What does it mean if your 2-OH / 4-OH-E1 Balance result is too low?

A low 2-OH / 4-OH-E1 ratio indicates that your body is favoring the 4-hydroxyestrone (4-OH) pathway over the 2-hydroxyestrone (2-OH) pathway for estrogen metabolism. The 4-OH pathway is considered less desirable as it can produce reactive products that damage DNA, potentially leading to an increased risk of cancer development. In contrast, the 2-OH athway is seen as safer due to its anti-cancer properties and ability to block the action of stronger estrogens that may be carcinogenic.

Factors like diet, lifestyle choices, and genetic predispositions can influence this ratio. A low 2-OH / 4-OH-E1 ratio may suggest an imbalance in estrogen metabolism that could impact health outcomes, particularly in relation to cancer risk. It's important to address underlying causes of this ratio imbalance to optimize estrogen metabolism and reduce potential health risks associated with an over-reliance on the 4-OH pathway.

Important Note: If Estrogen metabolite levels are very low, the reproducibility of the test is not as ideal, so calculated ratios (for the methylation-activity index and phase I estrogen metabolism ratios) are more approximate, less certain, and may not be reported.

What Healthmatters Members Are Saying

5 stars rating

I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with  any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
