Six Common Supplements Doctors Actually Recommend

Supplements have become a common addition to many people's daily routines, with about half of adults and one-third of children in the United States using them regularly. Despite the prevalence of these products, experts express caution regarding their safety and efficacy. The general recommendation from health professionals is to obtain nutrients primarily through a balanced diet rather than relying on supplements. Compounding this issue, the FDA does not require supplements to undergo rigorous safety or effectiveness testing before they are available to consumers. According to Dr. Jeffrey Linder, an internist and professor at Northwestern University, “a vast majority of supplements are probably worthless.” However, there are exceptions; some medical professionals do take particular supplements and have specific reasons for choosing them. Here are six supplements commonly taken by doctors and the rationale behind their use.

Vitamin D

Function: Vitamin D is essential for bone health and immune function. A deficiency in vitamin D has been linked to numerous health conditions, including autoimmune diseases, certain cancers, and cardiovascular problems, as well as seasonal affective disorder (SAD).

Why Doctors Use It: Vitamin D deficiency is prevalent, particularly among individuals living in northern regions with limited sun exposure and those with darker skin. Given that few foods are rich in vitamin D, many medical professionals consider supplementation necessary. Dr. Lawrence Green, a dermatologist, notes that nearly all physicians he spoke with take vitamin D supplements, especially during winter months when sun exposure is minimal.

Practical Advice: Most healthcare professionals recommend choosing vitamin D3 (cholecalciferol) over D2 (ergocalciferol) for better efficacy. Taking vitamin D with food containing fat can enhance absorption, an approach advocated by Dr. Sara Velayati, an obesity medicine specialist.

Calcium

Function: Calcium is crucial for building and maintaining strong bones and teeth. Its importance increases for women in their 40s who are approaching menopause, as changes during this phase can accelerate bone loss.

Who Takes It: Ideally, calcium should come from dietary sources. However, Dr. Rachel Pessah-Pollack, an endocrinologist, explains that many individuals may not meet their calcium needs through diet alone. She recommends a combination supplement with calcium and vitamin D, as vitamin D aids calcium absorption.

How to Supplement: There are different types of calcium supplements: calcium carbonate should be taken with food for optimal absorption, while calcium citrate can be taken with or without food.

Magnesium

Function: Magnesium plays a significant role in promoting restful sleep and aiding muscle recovery. Some studies suggest it may help reduce the frequency and severity of migraines.

Reasons for Use: Both Dr. Velayati and Dr. Raquel Zemtsov take magnesium supplements, with Zemtsov using it to alleviate migraine symptoms. Other doctors report using magnesium to enhance sleep quality.

Considerations: Different forms of magnesium can have varying levels of gastrointestinal tolerance. For instance, magnesium glycinate is often recommended for individuals prone to gastrointestinal upset, while magnesium oxide is particularly beneficial for migraine prevention. Taking magnesium supplements with food may further reduce gastrointestinal distress.

Omega-3 Fatty Acids

Function: Omega-3 fatty acids are vital for cardiovascular health and possess anti-inflammatory properties. Common sources include fish oil and krill oil.

Testimonials: Doctors like Dr. Sheeva Talebian, Dr. Jordan, and Dr. Velayati endorse omega-3 supplements for their potential benefits for brain health. Dr. Jordan specifically reports taking krill oil due to its superior absorption and reduced likelihood of causing a fishy aftertaste.

Usage Tips: To optimize absorption of omega-3s, it’s recommended to take them with meals that contain dietary fats. This is similar to the absorption tips for vitamin D.

Iron

Role: Iron is a crucial mineral that aids in creating hemoglobin, which carries oxygen in the blood. Insufficient iron can lead to anemia, resulting in fatigue and other health issues.

Who Benefits: Women are especially prone to iron deficiency, often due to menstrual blood loss. Dr. Zemtsov strategically takes ferrous gluconate when facing deficiencies, as it is absorbed well and tends to have fewer side effects. Dr. Jordan highlights that iron can also support energy levels and overall vitality.

Enhancing Absorption: Pairing iron with vitamin C-rich foods may improve absorption, making this a practical strategy for those considering iron supplements.

Fiber

Importance: Dietary fiber is essential for digestion, helps maintain fullness, supports bowel health, and can play a role in stable blood sugar levels and lowering harmful cholesterol.

Usage Advice: Dr. Jordan notes that many people fall short of the recommended fiber intake of 25 to 30 grams daily. She finds that a fiber supplement can help address this deficit, particularly for managing prediabetes and cholesterol levels. It's advisable to start with smaller doses to prevent digestive discomfort.

Hydration and Adjustment: Increasing fiber intake should be accompanied by a rise in water consumption to prevent gastrointestinal issues like bloating and gas.

Choosing Supplements Wisely

When considering any supplement, it’s essential to have a targeted reason for its use, ideally based on a confirmed deficiency or health need. Dr. Velayati emphasizes that supplements should complement, not replace, a healthy diet and lifestyle.

Essential Takeaways:

• Consult a healthcare provider: Always discuss supplement use with a medical professional, especially if you take other medications.
• Beware of "natural" labels: A product's natural status doesn't guarantee safety or effectiveness.
• Opt for reputable brands: Look for products that have undergone third-party testing for quality assurance.
• Avoid excess: Be cautious of overdosing on certain nutrients, as this can lead to adverse effects, such as cardiovascular issues or kidney stones.

It’s clear that while many doctors use certain supplements, their use is guided by specific health needs and quality considerations rather than a blanket approach to supplementation. Optimizing health still relies heavily on a balanced diet, regular exercise, and good sleep hygiene.
