The Role of Birth Control in Nutrient Depletion

Did you know that your birth control might put you at risk for having nutrient deficiencies?!



It has become incredibly common for women to regularly take oral birth control pills. As stated by the CDC, in 2017, 22% of women in the US were taking the pill as their chosen form of contraception.


In this blog post, I want to share with you what nutrients you may be low in from your birth control pills.


So, why is this a concern? Well, low nutrient levels can lead to a variety of bothersome and unwanted symptoms. The nutrients we'll be talking about include B vitamins like B12, B6. Riboflavin, and Folic Acid, along with other nutrients such as Magnesium, zinc, and Vitamin C.


Let's start with the nutrient that is estimated to be low in a whopping 75% of Americans!


Magnesium


This nutrient is known to benefit bone health, muscle and nerve functioning, diabetes, and those who experience migraines. People can be deficient in Magnesium for different reasons, however women taking oral contraceptives are at a higher risk for deficiency. Birth control actually has the ability to reduce levels of magnesium in the body. Some symptoms of magnesium deficiency are muscle pains, nausea, vomiting, weakness, osteoporosis, fatigue, high blood sugar, headaches/migraines, and premenstrual syndrome (PMS).


Wait. PMS? Isn't that a normal part of having a period?

NO, it's actually not. You shouldn't consistently experience bad PMS while on your period. You should not be dealing with severe PMS symptoms that interfere with your everyday life!


So, the point is, in order to combat the symptoms of magnesium deficiency, women taking oral birth control pills should try to be extra aware of their magnesium intake. Women can include more food high in magnesium into their eating plan or take a supplement if that is preferred.


The RDA (Recommended Dietary Allowance) for magnesium in women is about 310-320 milligrams (mg) per day.


Magnesium is found in dietary sources such as green leafy vegetables, legumes, nuts, seeds, and whole grains.




Some foods high in Magnesium:

Cooked black beans - 120 mg per cup

Spinach - 156 mg per cup

Pumpkin seeds - 168 mg per oz

Almonds - 80 mg per oz

Cashews - 74 mg per oz


Vitamin B6


This nutrient is known for its relationship with the brain, and more specifically mental health. B6 is very important to the central nervous system and plays a role in the production of neurotransmitters. It may be beneficial for mood regulation, brain function, reducing symptoms of depression, and managing PMS.


It has been found that the correlation between birth control pills and depression may be a result of the pill's tendency to cause Vitamin B6 deficiency. It is necessary for the body to have enough Vitamin B6 in order to produce the chemical serotonin, which stabilizes a person's mood. The most prominent symptoms of Vitamin B6 deficiency are irritability, depression, PMS, memory loss, and poor concentration.


Hold on a minute, does that mean oral contraceptives can contribute to depression? Is the pill responsible for moodiness?


Well, what happens is long term use of the pill could be depleting your body's levels of Vitamin B6, which could then bring those issues to the surface. Now, this doesn't mean you should stop taking the pill in order to avoid a depletion, but you should take the necessary actions to support your health and monitor your nutrient consumption. To alleviate the symptoms of a deficiency, women can make the necessary changes to their diet and consider the use of a supplement.


The RDA for Vitamin B6 for women is 1.3-1.5 mg per day. The highest amount of B6 is found in beef, fish, starchy vegetables, and fruits that are not citrus-based.


Specific food sources of Vitamin B6 includes:

Chickpeas - 1.1 mg per 1 cup

Beef liver - 0.9 mg per 3 oz.

Salmon - 0.6 mg per 3 oz.

Potatoes - 0.4 mg per cup

Banana - 0.4 mg per 1 medium fruit


Vitamin C



This nutrient is necessary for producing collagen, supporting the immune system, healing wounds, and bone health. Vitamin C is an antioxidant and is crucial for boosting immunity and fighting chronic diseases.


Have you ever been told to focus on getting some Vitamin C when you're sick?

We've all heard the idea that Vitamin C is detrimental for fighting off or preventing the common cold, right?! Vitamin C truly has a reputation for benefitting immune function.


Oral contraceptives like the pill have been found to potentially cause a depletion of Vitamin C, and therefore reduce its beneficial effects on the body. Some common symptoms of Vitamin C deficiency are scurvy, arthritis, gingivitis, poor wound healing, and infections. The possible lack of Vitamin C from taking birth control prevents the body from fighting off infections well.


Becoming deficient in Vitamin C is not good for your overall health status, and over time can be degrading to oral and physical health.


For women, the RDA for Vitamin C is 75 mg.

The best quality of Vitamin C comes from citrus fruits or juices, and many vegetables.

Some food sources high in vitamin C are:

Red pepper - 95 mg per ½ cup raw

Orange juice - 93 mg per ¾ cup

Orange - 70 mg per 1 medium fruit

Grapefruit - 78 mg per 1 medium fruit

Broccoli - 102 mg per cup cooked


Zinc

This nutrient supports metabolism and immune function within the body. Zinc is important for gene expression, release of hormones, healing from wounds, neurological function, as well as growth and development.


Some symptoms of a zinc deficiency are weakened immunity, lack of appetite, changes in taste, poor wound healing, and diarrhea. When levels of zinc are too low, a person is much more susceptible to diseases and sickness.


Research has revealed that women taking oral birth control pills were displaying a lack of zinc as well as low bone density. Women may also experience acne, hair loss/thinning, or loss of period related to zinc deficiency. These are common side effects while being on birth control, but it may be caused by inadequate zinc levels.


Whoa, those are some serious side effects from birth control and zinc deficiency. Do you know anyone who has lost their period?


Well, in some cases oral contraceptives may be responsible for amenorrhea caused by nutrient depletion. The disappearance of a regular and healthy menstrual cycle is a huge concern, and there's a chance it relates to a deeper issue with birth control. Usually we wouldn't guess that an oral birth control pill could be causing a woman to lose their period, but in reality, this is possible!


For women, the RDA for zinc is 8mg.

Zinc is found mostly in red meat, poultry, seafood, beans, nuts, and some whole grain products.

Some good dietary sources of zinc include:

Oysters - 74 mg per 3 oz

Roasted beef - 7 mg per 3 oz.

Cooked crab - 6.5 mg per 3 oz.

Canned Baked beans - 5.8 mg per cup

Cashews - 7.7 mg per cup


Vitamin B12


This is a nutrient that works to maintain the health of nerve and blood cells, promotes red blood cell production, creates DNA, prevents anemia, provides support for energy production, and aids brain development. Additionally, Vitamin B12 is considered essential, therefore the body needs it in order to function properly.


Some symptoms of Vitamin B12 deficiency include anemia, weakness, constipation, weight loss, confusion, memory loss, and neuropathy. Unfortunately, oral contraceptives have been shown to decrease the levels of Vitamin B12 in the blood leading to a deficiency in women.


In knowing that, it's very beneficial for women to be increasing their Vitamin B12 intake especially while on the the pill.


The RDA of Vitamin B12 for women is 2.4 mcg per day.

Where can you find good sources of B12?

The best quality of Vitamin B12 comes from animal foods, and some dairy sources of dairy.

Some examples would be:

Cooked clams - 84.1 mcg per 3 oz.

Cooked beef liver - 5.4 mcg per 3 oz.

Cooked salmon - 4.8 mcg per 3 oz.

Canned tuna - 2.5 mcg per 3 oz.

Low-fat milk - 1.2 mcg per cup


Folate


Folate is the natural form of Vitamin B9. Folate is known to make both the red and white blood cells found in bone marrow, support tissue growth, support tissue growth, as well as DNA and RNA production. It's vital to production of proteins and other cellular reactions that make take place in the body.


The most common symptoms of Folate deficiency are poor appetite, tongue inflammation, irritated gums, shortness of breath, brain fog, and irritability. A deficiency in Folate tends to result in Folate-deficiency anemia, where there is not enough Folate in the blood. When this happens, red blood cells will not be produced in adequate quantities.


There are studies presenting a consistency in Folate depletion among women taking oral contraceptives compared to women that are using other non-oral forms. Basically, birth control could possibly be causing women that are using other non-oral forms. Basically, birth control could possibly be causing women a variety of confusing problems, one of which may be anemia.


The RDA for Folate for women in 400 micrograms(mcg) per day.

The best quality of Folate can be found in legumes, many dark leafy green vegetables, rice, pastas, grains, and meat products.


Good examples of dietary Folate sources are:

Cooked beef liver - 215 mcg per 3 oz.

Cooked white rice - 180 mcg per cup

Cooked kidney beans - 131 mcg per cup

Cooked asparagus - 134 mcg per ½ cup (approx. 6 spears)

Spinach raw - 58 mcg per cup

Cooked Brussels sprouts - 156 mcg per cup


Riboflavin


Also known as Vitamin B2, Riboflavin plays a role in energy production, normal cell growth and development. It also assists in the breakdown of carbohydrates, proteins, and fats in the body. Riboflavin impacts the development of a person's skin and status of the lining within the digestive system. This nutrient also affects the eye health by protecting the antioxidants that are found in our eyes.


It has been discovered that oral contraceptives are linked to cases of women facing deficiencies in Riboflavin. Some of the symptoms consistent with a Riboflavin deficiency are gingivitis, eye irritation or itching, becoming sensitive to light, dermatitis, indigestion, and headaches. Birth control pills are capable of reducing the absorption or utilization of Riboflavin in the body.


The RDA for Riboflavin for women is 1.1 mg per day.

The highest quality sources of Riboflavin are found in lean meats, organ meats, dairy products, grains, and cereals.



Some good examples of food sources include:

Beef tenderloin steak - 0.4 mg per 3 oz.

Instant oats - 1.1 mg per cup

Mushrooms - 0.6 mg per cup

Almonds - 0.3 mg per 1 oz.

Plain fat free yogurt - 0.6 mg per cup

Scrambled eggs - 0.2 mg per large egg




What can I do?


Although women can focus on making dietary changes in order to combat nutrient deficiencies, supplements are sometimes needed as it can be difficult to replace a low nutrient level with just food. Further, you could check your cellular nutrient levels by working with a function medicine dietitian.

But WHY can't I just supplement on my own? I thought supplements were safe?
