The supplement market is booming. From fitness trainers to wellness gurus, the whole internet is recommending supplements. But what many don’t understand is that supplements are not candies to pop on a whim. They contain compounds that can either benefit or harm your health. Yes, that’s right. Supplements can negatively affect your health if not taken properly. According to Dr. Jeremy London, a board-certified cardiovascular surgeon with more than 25 years of clinical experience, people should pause before adding any new supplement to their daily routine. The doctor emphasized the importance of asking certain questions before taking supplements. So what are those questions you should be asking? Take a look

Questions to ask before taking supplements

Zinc is a catalyst
Before considering any supplements, start with the basics. “First, what is the supplement? What does it do? What can you expect? And is it relevant to your goals?” Dr. London said.Supplements are often marketed with big health claims, but do they really offer the benefits promised on the label? It is important to understand what the product is intended for, and whether it aligns with personal health objectives.

Is there scientific evidence

The cardiac surgeon stressed the importance of data and research when evaluating a supplement.
“Is there adequate scientific and clinical evidence that there's any benefit to the supplement? Is it possible to bridge these gaps with lifestyle changes and alterations in your nutritional plan?” Dr. London said.

Has it been third-party tested?

One of the biggest concerns when it comes to the supplement industry is the lack of quality control. The regulations are often less stringent than medications. That’s where third-party testing comes into play. “This simply ensures that what's on the label is actually what you're putting in your mouth,” the doctor says.

Be aware of the risks

Do not expect that supplements are free of side effects. Even natural or plant-based products may have some risks. The supplements can interact with your prescription medications and could worsen underlying conditions, or even cause unwanted side effects. “Be aware of any pitfalls or dangers or risks, interactions with any medications you may be taking, or associations with any medical history that you may have,” the surgeon said.

Do you really need supplements

Everyone is talking about it. The health influencers are probably advertising the supplements and raving about their numerous benefits. But should you really take it? Most importantly, can supplements substitute for the lack in your nutrition? Dr. London explains that supplements are not a substitute for diet. “In the end, these are supplements, not substitutions for thoughtful lifestyle choices, a high-quality whole foods diet, and adequate hydration,” he adds.
