- Magnesium form matters most: glycinate and bisglycinate are best absorbed and most studied for sleep — avoid oxide
- B1 form also matters: benfotiamine (fat-soluble) has higher bioavailability than standard thiamine HCl — useful if you suspect deficiency
- Take magnesium in the evening — that's when studies show the best effect on sleep onset and quality
- Who benefits most from magnesium: older adults, high stress, poor diet. From B1: regular alcohol use, restrictive diet, people sleeping too long and still feeling tired
- Look for Health Canada approval on Canadian products — it means the product has met federal quality standards before reaching shelves
What to look for on the label
Canada has stronger supplement regulation than the US — products sold here require a Natural Product Number (NPN) issued by Health Canada, which means they've passed a review for safety, efficacy, and quality before going on sale. That said, the form of the nutrient still matters. For magnesium, look for glycinate, bisglycinate, or citrate on the label — avoid oxide, which is poorly absorbed. For B1, thiamine HCl is the standard effective form found in most Canadian brands.
Where we list international brands alongside Canadian ones, it's because they offer a meaningfully different formulation or quality tier worth knowing about — not because Canadian brands are inferior. The two Canadian picks in each section are our first recommendation.
