How certain medications & health conditions can impact nutrient levels
Published July 27, 2024
Nutrients are essential for every part of you—from bone strength to brain power. They're not just important for health, they're vital for life.¹ But getting enough goes beyond what is (or isn’t) on your plate. Other factors like oral contraceptives, thyroid disorders, and celiac disease, can impact your body’s ability to absorb or use nutrients.² ³ This can lead to deficiencies with a wide range of health effects.¹⁻³
It’s an issue impacting far too many.
31% of Americans, or nearly 1 in 3, are at risk of nutrient deficiency or anemia.⁴
This article focuses on how 3 factors—oral contraceptives, thyroid disorders, and celiac disease—can affect nutrient levels.² ³ You'll learn which nutrients are most at risk, what they do, and how your body might tell you it’s running low.
1. Oral contraceptives
Oral contraceptives (birth control pills or "the pill") revolutionized women's reproductive health since their introduction in 1960.² These medications work by delivering synthetic hormones, either a combination of estrogen and progestin or progestin only. When taken as directed, they offer a highly effective method of preventing pregnancy by⁵:
- Reducing or stopping ovulation
- Thickening cervical mucus, making it difficult for sperm to enter the uterus
- Thinning the lining of the uterus, making it less receptive to a fertilized egg
These medications are also prescribed to help treat certain medical conditions and manage their symptoms.⁵ Though effective for their intended purposes, oral contraceptives can also negatively impact nutrient levels in the body.²
7 nutrient deficiencies linked to oral contraceptives[² ⁶⁻¹³]

• Anemia • Cracked corners of mouth • Irritability, mood changes • Sore or swollen tongue • Weakened immune system |
Vitamin B9 (folate, folic acid) | • Grows tissues • Helps break down, use, and create proteins • Helps build DNA • Makes red blood cells • Supports cell function |
• Headache • Irritability, mood changes • Shortness of breath • Sore or swollen tongue • Weakness, tiredness |
Vitamin E (alpha-tocopherol) | • Helps heal wounds • Helps with blood clotting • Promotes heart health • Regulates blood calcium levels • Supports bone and tissue health |

Nearly 1 in 7 women in the US (ages 15–49) use oral contraceptives,¹⁴ which can deplete nutrients and cause side effects.²
Better understand your nutrient levels with Quest’s Nutrient Deficiency Panel for Oral Contraceptive Patients, designed for those taking birth control pills. Our panel measures 7 nutrients that oral contraceptives can impact: magnesium, phosphorus, selenium, vitamin B6 (pyridoxine), vitamin B9 (folate), vitamin E, and zinc.
2. Thyroid disorders
The thyroid is a small, butterfly-shaped gland located in the front of your neck. It produces and releases hormones that control vital bodily functions. These hormones regulate your metabolism, the process that converts the food you eat into energy—the fuel powering every cell in your body. If your thyroid isn’t working properly, it can affect your entire body and overall health.¹⁵
Thyroid disorders can cause the thyroid to produce and release abnormal levels of thyroid hormones. This can lead to either too much (hyperthyroidism) or too little (hypothyroidism) of these hormones in your body. Approximately 20 million Americans have some form of thyroid disorder, including¹⁵:
- Goiter (enlarged thyroid)
- Hashimoto’s thyroiditis (an autoimmune disorder)
- Hyperthyroidism (overactive thyroid)
- Hypothyroidism (underactive thyroid)
- Iodine deficiency
- Thyroid nodules (lumps in the thyroid)
- Thyroiditis (swelling of the thyroid)
- Thyroid cancer
Thyroid health and nutrition go hand in hand. Your thyroid relies on nutrients like iodine, iron, selenium, and vitamin D to function properly.[¹⁶⁻¹⁸] A lack of certain nutrients can cause thyroid disorders. But there’s a twist. Thyroid disorders can also cause nutrient deficiencies. This can create a challenging cycle where thyroid disorders and nutrient deficiencies feed into—and potentially worsen—each other.¹⁶

Joint pain, brain fog, or feeling like you’re running on empty?
Thyroid health and nutrition go hand in hand.
Quest’s Thyroid Disorder Nutrient Deficiency Panel measures iodine, iron, selenium, and vitamin D to help identify nutrient gaps linked to thyroid disorders.
3. Celiac disease
Celiac disease is an autoimmune disorder that affects the small intestine. When someone with celiac disease eats gluten, it triggers an immune system response. This response damages the lining of the small intestine, making it difficult for the body to absorb nutrients (malabsorption). This can lead to nutrient deficiencies and a variety of health issues.²³
While a gluten-free diet is essential for managing celiac disease and preventing further damage, it can also cause nutritional deficiencies. Many gluten-free foods lack the added nutrients found in those containing gluten. This can lead to a lower intake of important vitamins and minerals—even while successfully avoiding gluten.²³

If you’re considering a supplement, check what your body needs first.
Taking too much of certain nutrients can be harmful to your health.¹
Vitamins and minerals are important, but more isn’t always better.¹ If you’re considering a supplement, it’s best to first check your nutrient levels and talk with a doctor for advice. This way, you’ll know what your body needs—if anything—and can avoid taking too much.
