Supplements: How to pick, use, and buy them without wasting money
Ever spent money on a supplement that did nothing? You're not alone. Supplements can help fill gaps, support recovery, or ease symptoms — but only when chosen and used the right way. This page collects straightforward, practical posts from Canadian-Tabls to help you shop smarter, avoid risks, and get results.
Quick rules for choosing a supplement
Start with a simple question: why do you want it? If it's for a diagnosed deficiency (low vitamin D, low B12, etc.), get blood tests and a dose from your clinician. If it's for general health, pick basic options with proven benefits — multivitamins, vitamin D in winter, or omega-3s if your diet lacks fatty fish.
Look for third-party testing. Labels that mention USP, NSF, or ConsumerLab mean the product was tested for purity and label accuracy. Avoid bold claims like "miracle cure" or "rapid weight loss" — those are red flags. Check the ingredient list and total amounts, not just serving sizes.
Buy from stores with clear contact details and return policies. For online pharmacies, prefer licensed Canadian or international pharmacies with verifiable credentials. Our post on Canadian Pharmacy World explains how to spot sites that follow safe practices.
Safety, interactions, and dosing you can follow
Supplements can interact with meds. A classic example from our site: grapefruit affects some cholesterol drugs called statins by changing how the body breaks them down. If you take prescription meds, run every supplement by your doctor or pharmacist before starting it.
Keep doses simple. More isn’t always better. For amino acids like threonine, follow recommended ranges — too much can cause imbalance. For topical products like eflornithine cream, follow the application instructions exactly; topical use matters more than bulk dose. When in doubt, follow the product label and professional advice.
Watch for side effects. Upset stomach, headaches, or allergy-like symptoms can happen with new supplements. Stop and ask a professional if symptoms persist. For certain groups — pregnant people, breastfeeding parents, children, and people with chronic illnesses — get medical approval before starting any new supplement.
Practical buying tips: compare ingredients not brands, check expiration dates, and avoid multi-ingredient products that hide small doses of active parts. If a supplement promises the same benefit as a prescription drug, be skeptical.

Use supplements as tools, not fixes. When paired with good sleep, decent diet, and consistent medical care, they can help. If something seems off, stop and ask for professional advice — that quick step often saves time, money, and worry.
