Ensuring the safety of dietary supplements is crucial for maintaining health and preventing adverse effects. In this blog, we will discuss 10 key points to guide you when purchasing and taking supplements.

In many countries, dietary supplements are regulated differently than pharmaceuticals. In the United States, for example, the FDA does not approve supplements for safety and efficacy before they are marketed.
Understanding Supplement Safety & Choosing Safe Supplements: Let's Dive In!
1. Who is the Manufacturer?
Research the brand and look for reputable companies. Knowing the manufacturer helps ensure you are purchasing a quality product.
2. Ingredient Sourcing
Where does the supplement company source their ingredients? Are they locally or internationally sourced? Beware of botanical adulterants—these are potentially harmful substances added to botanical products to increase quantity. Such practices can pose health risks, including liver and kidney damage.
3. Quality Control
Choose products from companies that adhere to good manufacturing practices. Their products should be tested by independent organizations for purity and potency. Some supplements may contain harmful substances due to poor manufacturing practices. Therefore, it is imperative to buy high-quality supplements. Look for certifications such as non-GMO verified, USP verified, and GMP certified.
4. Storage and Shipping
The storage and shipping of supplements can affect their potency. Some supplements have specific requirements due to sensitivity to heat and light. Buying from random online sellers may not be wise, as they might not follow appropriate storage and shipping guidelines.
5. Beware of Counterfeits
Be cautious of counterfeits online, especially from social media marketers. You may not be able to trace any information about the product aside from its name.
6. Outrageous Prices
If the price seems too high, do your research! An expensive product does not guarantee quality.
7. Read Labels Carefully
Pay attention to ingredient lists and avoid products with unnecessary fillers or additives. Some individuals may experience allergic reactions or side effects from certain ingredients. Always read the Supplement Facts, Ingredients, and Other Ingredients—not just the name on the bottle. Also, check for Vegan, Keto-Friendly, Gluten-free, Dairy-free, and Soy-free labels if you have allergies or follow a special diet. Remember, zero sugar does not always mean healthy. Always check the expiration date before taking any supplement.
8. Dosage Matters
Taking more than the recommended dosage can lead to toxicity or health issues. Many people also underdose, which means they don't see any effects from the supplements. Remember, Serving Size and Suggested Use are not the same as Therapeutic Dose. The Therapeutic Dose is the amount known to be effective without causing significant adverse effects. It is crucial to work with a healthcare professional, like a licensed Naturopathic Medical Doctor, to guide you in therapeutic dosing.
9. Drug-to-Supplement & Supplement-to-Supplement Interactions
Supplements can interact with prescription medications and other supplements, potentially altering their effectiveness and posing risks to your health. Always check with your healthcare provider before starting any supplement.
10. Proper Timing When Taking Supplements
The effectiveness of a supplement depends on knowing when and how to take it. Is it best taken in the morning, afternoon, or evening? Should it be taken with or without food? Thoroughly read the directions on the bottle or package.
Consult Healthcare Professionals
Always discuss with your doctor or a registered dietitian before starting new supplements, especially if you have underlying health conditions or are taking medication. There is much to learn about supplements that may not be on the supplement bottle or the manufacturer's website. Licensed Naturopathic Medical Doctors are trained in botanical medicine and supplements and are a great resource to consult.
Conclusion
While dietary supplements can provide health benefits, it is essential to prioritize safety. By being informed and cautious, individuals can minimize risks and make better choices regarding their supplement use.
