If you've ever stood in a supplement aisle (or scrolled through Amazon) feeling completely overwhelmed, you're not alone. There are thousands of products making the same claims, at wildly different price points, and most labels aren't exactly easy to decode.
Here's the thing: not all supplements are created equal. What's inside the bottle, how much of it is there, and what form it's in can make the difference between a supplement that actually works and one that's basically doing nothing. And more expensive doesn't always mean better. But going for the cheapest option isn't always the right call either.
These are the four things I check before recommending any supplement to a patient.
1. Is the Dose Clinically Meaningful?
This is one of the most common issues I see. A supplement can contain the right ingredient, but if the dose is too low, it won't do what you're hoping it will. Many products on store shelves are technically "correctly labelled" but use sub-therapeutic amounts that don't reflect what the research actually supports.
When you're looking at a label, check the dose per serving against what's been studied. If you're not sure what a therapeutic dose looks like for a particular nutrient or herb, that's a great question to bring to your naturopath.
2. What Form Is It In?
The form of a nutrient or herb matters a lot, and this one catches people off guard regularly.
For nutrients, different forms have very different absorption rates. Magnesium oxide, for example, is cheap and common but poorly absorbed. Magnesium bisglycinate is much better tolerated and more bioavailable. The same principle applies to things like iron, B12, zinc, and folate. The form on the label tells you a lot about how well your body is actually going to use it.
For herbal supplements, it's worth looking at which part of the plant was used (root vs. leaf vs. aerial parts) and whether it's a standardized extract. Research on herbs is often done using a specific extract at a specific concentration. If your product doesn't match that, you may not get the same results.
3. Is It Third-Party Tested?
This one matters more than most people realize. The supplement industry is not as tightly regulated as pharmaceutical drugs, which means products don't always contain exactly what they say they do. Some contain less of the active ingredient than listed. Some contain contaminants.
In Canada, look for an NPN (Natural Product Number) on the label, it means Health Canada has reviewed it. From there, choosing products made in Canada under GMP (Good Manufacturing Practices) standards gives you an extra layer of confidence in what you're actually getting. Many quality brands will also note third-party testing right on the label or describe their testing process on their website, so it's worth a quick check before you buy.
4. What Else Is in There?
Flip the bottle over and look at the non-medicinal or "other ingredients" section. This is where fillers, binders, artificial colours, and additives show up.
Some of these are benign. Others are worth avoiding, depending on your sensitivities. Talc (magnesium silicate) is one I flag regularly. Artificial dyes, titanium dioxide, and certain preservatives are others. For patients with digestive issues, sensitivities, or autoimmune conditions, this part of the label actually matters quite a bit.
A cleaner "other ingredients" list doesn't automatically make a product better, but it's a useful signal about how much the manufacturer is paying attention to quality.
A Note on Price
More expensive does not equal better. There are high-quality, well-formulated supplements at reasonable price points, and there are overpriced products with very little to back them up. That said, you generally don't want the absolute cheapest option either. Very low prices often reflect low-quality raw materials, poor manufacturing standards, or doses that won't actually move the needle.
The goal is value: a product that uses the right form, the right dose, from a manufacturer that takes quality seriously. That usually falls somewhere in the middle.
The Bottom Line
Supplements can be a genuinely useful part of a health plan, but they're not all interchangeable. Taking something in the wrong form, at the wrong dose, from a manufacturer that skips quality controls means you're spending money and not getting results.
If you're not sure where to start or whether what you're taking is actually working for you, that's exactly the kind of thing we sort out together.
