Estrogens and Related Drugs: A Deeper Dive into Nutrient Deficiencies and Strategies for Optimal Nutritional Health

Over 1.3 million women in the United States are affected by menopausal symptoms yearly.

What is Menopause?

Menopause begins approximately 12 months after a woman's last menstrual cycle. It can happen anytime in your 40s and 50s, but on average, it occurs around the age of 51. It’s triggered by decreasing levels of estrogen and progesterone produced by the ovaries.

It is a natural biological process that can affect a woman in many ways, such as hot flashes, weight gain, trouble sleeping, and emotional health problems.

What are Estrogen-Related Drugs?

Estrogen-related drugs, including hormone replacement therapies (HRT), are commonly employed to manage menopausal symptoms, affecting approximately 1.3 million women in the United States annually. 

So, what are estrogen-related drugs? Estrogen-related drugs counter the natural decline in estrogen levels, which is responsible for many menopausal symptoms.

Common pharmaceutical brands and names of estrogen-related drugs include estradiol (Estrace, Climara, Vivelle-Dot), conjugated estrogens (Premarin), and esterified estrogens (Menest). Each of these medications carries a unique potency and side effect profile, and the choice of therapy is typically tailored to the patient's specific needs and overall health condition.

Side Effects of Estrogen-Related Drugs

Despite their efficacy in alleviating these symptoms, prolonged use of these medications can lead to certain nutrient deficiencies. This article will explore these deficiencies, their implications, and strategies for effective management.

While estrogen-related drugs are generally safe and effective, they can affect specific nutrients, notably vitamins B6, B12, and folate. Not every individual on estrogen-related drug therapy will develop these deficiencies, but awareness of potential risks is crucial.

Vitamin B6 Deficiency

Long-term use of estrogen-related drugs can affect vitamin B6 levels, potentially leading to peripheral neuropathy. A study in the American Journal of Clinical Nutrition (1992) found that oral contraceptive users, another group of estrogen users, had lower serum vitamin B6 levels.

Solution: Regular monitoring of vitamin B6 levels is recommended for long-term estrogen-related drug therapy patients. If necessary, dietary adjustments to include vitamin B6-rich foods or supplementation might be recommended under the guidance of a healthcare provider.

Vitamin B12 Deficiency

Estrogen-related drugs can interfere with the absorption of vitamin B12, potentially leading to deficiency over time. A study in the Journal of Clinical Endocrinology & Metabolism (2009) found a higher prevalence of vitamin B12 deficiency in long-term users of oral contraceptives.

Solution: Regular monitoring of vitamin B12 levels and potential supplementation might be necessary for patients on these medications. A diet rich in vitamin B12 may also be recommended.

Folate Deficiency

Similar to vitamin B12, estrogen-related drugs can interfere with folate absorption. A study in the American Journal of Clinical Nutrition (1995) found lower serum folate levels in users of estrogen-related drugs.

Solution: Regular monitoring of folate levels and potential supplementation may benefit patients on estrogen-related drugs. A diet rich in folate may also be advised.

Importance of Testing and Supplementation

As not everybody on an estrogen-related regimen will experience these deficiencies, it is essential to do regular tests for potential deficiencies, as not all symptoms are indicative. Many supplements counter these deficiencies and allow patients to lead a balanced life.


Estrogen-related drugs are instrumental in managing menopausal symptoms. However, their long-term use can lead to certain nutrient deficiencies, namely vitamin B6, vitamin B12, and folate. By staying informed about these potential deficiencies and addressing them promptly through regular testing and potential supplementation or dietary adjustments, patients on estrogen-related drugs can continue to live a healthy, balanced life.

Always remember that any medication or supplementation should be under the guidance of a healthcare provider to ensure its safety and effectiveness.
