Dietary supplements are intended to add to or supplement the diet and are different from conventional food. While a well-balanced diet usually provides sufficient amounts of micronutrients, some people may need specific supplements to help with deficiencies. However, it's important to note that supplements can sometimes interact with each other and with over-the-counter (OTC) and prescription medications, which can be dangerous. The U.S. Food and Drug Administration (FDA) does not approve dietary supplements for safety and effectiveness before they are sold to the public, so it's crucial to consult a healthcare professional before taking any supplements, especially if you are also taking any medications.

What You'll Learn
Dietary supplements and prescription medications
Mixing dietary supplements and prescription medications can have dangerous and even life-threatening consequences. According to the National Center for Complementary and Integrative Health, millions of adults in the United States take dietary supplements along with their prescription medications. However, this combination can lead to harmful effects, including diminished drug effectiveness, increased risk of toxicity, and unexpected side effects.
It is crucial to consult a healthcare provider or pharmacist before taking any dietary supplement, especially when also taking prescription medications. Pharmacists are knowledgeable about drug interactions and can provide advice on safe supplement use, dose timing, and alternatives. They can also suggest dose adjustments to avoid potential conflicts. It is important to provide pharmacists with a comprehensive list of all medications and supplements to ensure an accurate assessment.
Some specific examples of supplements that may interact with prescription medications include St. John's Wort, which can reduce the effectiveness of drugs for HIV/AIDS, heart disease, depression, organ transplants, and birth control pills. Additionally, vitamin E, when combined with blood-thinning medication, can increase the risk of internal bleeding or stroke. Other supplements such as vitamin K can counter the effects of certain medications, and vitamin B6 can interact with levodopa.
Timing is also a critical factor when combining supplements and medications. For instance, thyroid hormone medications should be taken on an empty stomach, separated from supplements containing calcium and iron by at least four hours. Similarly, osteoporosis and diabetes medications should be taken at least 30 minutes apart from other medications.
It is important to note that the Food and Drug Administration (FDA) does not review supplements for effectiveness or safety before they enter the market. Therefore, it is the responsibility of the consumer to be vigilant and consult with healthcare professionals to ensure safe supplement and medication combinations.

High doses of vitamin D supplements
Dietary supplements can be beneficial to your health, but they can also involve health risks. It is important to consult a healthcare professional before taking any supplements, especially if you are currently taking any medications.
According to research published in The Journal of the American Medical Association (JAMA), there has been an increase in the number of people taking potentially unsafe amounts of vitamin D, which is considered to be more than 4,000 International Units (IU) per day. This is significantly higher than the recommended dose of 600 to 800 IU for most individuals.
Excessive vitamin D intake can lead to a condition known as vitamin D toxicity or hypervitaminosis D. This occurs when there is too much vitamin D in the body, usually from taking high doses of supplements or prescription medication. Vitamin D toxicity is a rare complication, with approximately 4,500 cases reported annually in the United States. However, it can have serious health consequences. The main complication of vitamin D toxicity is hypercalcemia, a buildup of too much calcium in the blood. This can lead to the formation of deposits in the arteries or soft tissues and may predispose individuals to kidney stones. Symptoms of hypercalcemia include decreased appetite, nausea, vomiting, increased thirst, and frequent urination.
To avoid the risks associated with high doses of vitamin D supplements, it is crucial to practice moderation and consult with a healthcare professional to determine the appropriate dosage for your specific needs. It is also worth noting that a well-balanced diet that includes good sources of vitamin D may eliminate the need for supplements altogether.

Omega-3 supplements and Coumadin (warfarin)
Dietary supplements can be beneficial to your health, but they can also involve health risks. It is important to consult a healthcare professional before taking a new supplement, especially if you are already taking medications.
Omega-3 supplements, such as fish oil, are a popular choice for those looking to improve their health. Fish oil is an omega-3 polyunsaturated fatty acid that consists of eicosapentaenoic acid and docosahexaenoic acid. However, when combined with the prescription drug Coumadin (warfarin), omega-3 supplements may cause adverse effects.
Warfarin is a medication that helps prevent blood clots from forming or existing clots from getting larger. It is often prescribed for people at risk of blood clots, such as those with certain heart conditions or following some surgeries. Warfarin works by blocking the effects of vitamin K, which is needed for blood clotting.
When taken together, omega-3 supplements and warfarin may increase the risk of bleeding. This is because omega-3 fatty acids can affect platelet aggregation and/or vitamin K-dependent coagulation factors. In one case, a patient taking both fish oil and warfarin experienced an elevated international normalized ratio (INR), which measures the time it takes for blood to clot. The patient's INR increased from 2.8 to 4.3 within one month of doubling their fish oil dose, indicating a higher risk of bleeding. After reducing their fish oil intake, the patient's INR decreased to 1.6 within a week.
It is important to note that this interaction may be rare, and there are conflicting reports about the effects of combining omega-3 supplements and warfarin. However, patients taking warfarin should be educated about possible drug-herb interactions and monitored for any signs of unusual bleeding or bruising. If you are taking warfarin, it is crucial to consult your doctor before taking omega-3 supplements or making any changes to your diet or medication regimen.

Vitamin B6 and B12 deficiencies
Dietary supplements can be beneficial to your health, but they can also involve health risks. Mixing medications and supplements can be dangerous, and some combinations can be life-threatening. It is always a good idea to consult a healthcare professional before taking any supplements, especially if you are on prescription medication.
Vitamin B6, also known as pyridoxine, helps the body convert food into energy and supports the immune system. A B6 deficiency may cause mood changes, including depression, anxiety, and irritability. It can also lead to glossitis, an inflammation of the tongue that causes it to become swollen, sore, and smooth, resulting in difficulties with chewing, swallowing, and talking. B6 deficiencies are more common in people with liver, kidney, digestive, or autoimmune diseases and are also linked to smoking, obesity, alcoholism, and pregnancy.
A deficiency in both B6 and B12 can cause high homocysteine levels, which may damage blood vessels and nerves and increase the risk of disease. It is important to note that a varied diet of lean proteins, grains, fruits, and vegetables can provide the body with the required B vitamins in most cases.

Dietary supplements and natural foods
Dietary supplements can be beneficial to your health, but they can also involve health risks. It is important to consult a healthcare professional before taking any supplements, especially if you are already taking medications. Some medications and supplements can have serious, even life-threatening, interactions.
In the United States, the Food and Drug Administration (FDA) does not approve dietary supplements for safety and effectiveness before they are sold to the public. Instead, it is the responsibility of dietary supplement companies to ensure their products meet safety standards and comply with the law. However, companies are not required to publish studies alerting the public to safety concerns, and marketing often emphasizes "'natural'" ingredients, which may suggest safety.
Some supplements are advertised with false or unproven claims, such as curing diabetes or preventing serious diseases like cancer and heart disease. A product is considered a drug if it is intended to treat, diagnose, cure, or prevent diseases, even if it is labelled as a dietary supplement.
To avoid potential interactions, it is recommended to leave at least two hours between taking supplements and medications. It is also important to be aware of possible side effects or bad reactions, also known as adverse events, and to report them to the FDA if they occur.
