With so many vitamins and supplements available, how do you know which ones are safe, effective, and worth taking?
From immune support to better sleep, supplements may provide a wide range of health benefits. But not all products are created equal, and some may not contain what their labels claim.
The best way to choose safe supplements is to look for independent quality testing, buy from trusted sources, and talk with a qualified healthcare provider before starting something new.
At NUNM Health Centers in Portland, Oregon, we believe supplements should support your individual health needs, not replace a healthy diet or appropriate medical care.
Here’s what to know before purchasing your next supplement.
1. Talk with your Healthcare Provider Before Taking Supplements
Are supplements safe to take with medications? Not always.
Even products labeled “natural” can interact with prescription medications or other supplements. Certain herbs and vitamins may also be inappropriate for people with specific health conditions.
Your naturopathic doctor, Chinese medicine practitioner, or other qualified healthcare provider can help you determine whether a supplement is right for you.
They can also help you avoid taking products you may not need. Many essential nutrients can be obtained through a balanced, whole-foods diet. According to NIH Office of Dietary Supplements, supplements can help people meet their nutritional needs in certain situations, but they should not replace a healthy diet.
2. Follow the Recommended Dosage
When it comes to supplements, more isn’t always better.
Taking too much of certain vitamins or herbs can cause side effects. Some supplements may also become harmful when taken longer than recommended.
Follow your healthcare provider’s guidance on how much to take and for how long. If you’re unsure about a product’s dosage, ask before starting it.
3. Choose Supplements That Are Independently Tested
How can you tell whether a supplement is high quality?
For over-the-counter supplements commonly found at grocery stores and pharmacies, independent testing can be a helpful way to evaluate product quality.
Look for a certification seal on the label from organizations such as:
- USP (United States Pharmacopeia): Verifies that qualifying products meet established standards for ingredients, strength, and quality.
- NSF International: Offers certification programs that check whether supplements meet specific quality and safety standards.
- ConsumerLab: Independently tests supplements for ingredient accuracy and certain contaminants.
These programs can help you identify products that meet established quality standards.
However, these certifications aren’t the only way to identify quality supplements. Where you purchase your supplements also matters. Not all online retailers follow the same quality standards or sourcing practices as a professional dispensary.
At NUNM Health Centers, the products available through our Medicinary and Fullscript online dispensary are carefully selected for quality. Our healthcare providers recommend trusted supplement brands based on their quality standards and the needs of individual patients.
4. Look Beyond Marketing Claims
Just because a supplement promises better health doesn’t mean it delivers.
Some products make impressive claims about improving energy or boosting immunity without strong scientific evidence to support them.
Before purchasing a supplement, consider whether the benefits are supported by reliable research. Your healthcare provider can help you understand which products may be useful for your individual health needs.
5. Buy Supplements From Trusted Sources
Where you purchase your supplements matters.
Large online marketplaces offer convenience, but products may be sold by multiple third-party sellers. This can make it harder to verify where a supplement came from, how it was stored, or whether the product is authentic.
Buying through a professional healthcare dispensary is different.
Fullscript, the online supplement platform used by NUNM Health Centers, works with vetted brands and authorized distribution channels. This provides greater confidence in product sourcing and authenticity compared with purchasing from an unknown thrid-party marketplace seller.
Whenever possible, purchase supplements directly from a reputable manufacturer or a trusted healthcare dispensary.
Your healthcare provider can also recommend reliable sources for the products they suggest. Whether shopping in person or online, choose sources that prioritize product authenticity and reliable handling practices.
Where Can You Find Quality Supplements in Portland, Oregon?
For patients in Portland and surrounding communities, the NUNM Medicinary at NUNM Health Centers offers a selection of dietary supplements, Chinese and Western herbs, tinctures, and personal care products.
Quality is an important part of how we select the products available to our patients.
NUNM has adopted the Emerson Quality Program (EQP) as part of our Medicinary Quality Standards. The program evaluates participating brands through manufacturing documentation reviews, facility audits, and product testing.
For suppliers that do not participate in the EQP, we request independent certification of compliance with Current Good Manufacturing Practices.
These standards help us make thoughtful decisions about the products we carry so patients can feel more confident about their choices.
Frequently Asked Questions About Supplement Safety
Are natural supplements always safe?
No. Natural products can still cause side effects or interact with medications. It’s important to speak with a qualified healthcare provider before starting a supplement, especially if you take prescription medications or have an ongoing health condition.
How do I know if a supplement is good quality?
Look for independent testing from organizations such as USP, NSF International, or ConsumerLab. Choose reputable manufacturers that follow FDA manufacturing requirements and provide clear information about their ingredients.
Are expensive supplements better than cheaper ones?
Not necessarily. A higher price doesn’t always mean better quality. Independent testing, manufacturing standards, and appropriate ingredients are more useful ways to compare supplements.
Do I need to take vitamins if I eat a healthy diet?
Not everyone needs supplements. A balanced diet can provide many essential nutrients, but some people may benefit from supplementation based on their health needs or a diagnosed nutrient deficiency. Your healthcare provider can help you decide.
