InspireWebber Naturals Magnesium Bisglycinate Review (2026)
The front label says bisglycinate. The ingredient panel says something more specific, and it’s not just a Webber thing.

It’s a real, common, disclosed industry practice, not a reason to avoid this product, but worth knowing if you specifically want 100% pure bisglycinate.
- Webber Naturals Magnesium Bisglycinate 200mg: our pick for most people. Affordable, NPN-registered, widely available in Canada.
- Natural Factors PURE (powder): the pick if you specifically want zero oxide blend.
- AOR Magnesium Glycinate: also 100% pure, lower dose per capsule, needs 2-3 daily.

Key takeaways
Webber Naturals Magnesium Bisglycinate 200mg is a real, NPN-registered, Canadian-available supplement that does what it’s marketed to do: an easier-to-tolerate form of magnesium for muscle function and general supplementation. The one thing most reviews don’t mention is that it’s not 100% pure bisglycinate, it’s a buffered blend with magnesium oxide, disclosed in the ingredient panel but not emphasized on the front label. That’s genuinely common industry practice (we confirmed a major competitor does the same thing), not a Webber-specific problem. If it matters to you, we’ve included two alternatives that are confirmed 100% pure.

What’s actually on the label, and what isn’t emphasized
Webber Naturals’ front label says “Magnesium Bisglycinate 200 mg.” Flip to the actual medicinal ingredients panel and it reads: “Magnesium [buffered magnesium bisglycinate (bisglycinate, oxide)] 200 mg.” That’s a real, technical disclosure, magnesium oxide is genuinely part of the formula, just not called out on the front where most people look.
“Buffered magnesium bisglycinate” is a standard raw-ingredient grade used across the supplement industry, commonly cited around a 70/30 split (roughly 140mg elemental magnesium from bisglycinate, 60mg from oxide), though Webber’s own label doesn’t break out that exact ratio, so treat the specific numbers as a well-supported estimate rather than a confirmed figure. We checked whether this was a Webber-specific shortcut: it isn’t. Natural Factors’ own standard “Magnesium Bisglycinate” capsule line uses the identical ingredient line, buffered blend included. This appears to be common industry practice for this grade of raw ingredient, not a single brand cutting corners.
The practical takeaway: if you don’t have a specific reason to need 100% pure bisglycinate, this doesn’t change much, both forms are absorbed and used by the body. If you’re specifically choosing bisglycinate because other forms of magnesium upset your stomach, the oxide content is worth knowing about, since oxide is the form most associated with a laxative effect.
Oxide vs. bisglycinate: what’s actually established
Magnesium oxide has low solubility and is poorly absorbed relative to other forms, it’s the same compound behind milk of magnesia, and is the form most commonly linked to a laxative/GI-upset effect at higher doses. Magnesium bisglycinate is bound to the amino acid glycine and absorbed through a different intestinal pathway, generally better tolerated with fewer GI complaints in comparative research. That part is reasonably well-established.
Where the marketing oversells it: some head-to-head studies don’t show bisglycinate dramatically outperforming other forms on raising blood magnesium levels. “Better tolerated” has real support. “Dramatically more effective” is a stronger claim than the evidence consistently backs.
For context, Health Canada’s recommended magnesium intake is 400-420mg/day for adult men and 310-320mg/day for adult women (from all sources, food included), with a tolerable upper limit of 350mg/day from supplements specifically. A single 200mg capsule is a meaningful contribution, not your full daily requirement on its own.

Frequently asked questions
Is Webber Naturals Magnesium Bisglycinate actually pure bisglycinate?
No, and this is disclosed (just not emphasized): the ingredient panel lists it as “buffered magnesium bisglycinate (bisglycinate, oxide).” It’s a blend, not 100% pure. This is common industry practice for this grade of raw ingredient, we confirmed Natural Factors’ standard capsule line does the same thing.
Is a bisglycinate/oxide blend bad for you?
Not inherently. Most people tolerate it fine. The main consideration is that magnesium oxide is more associated with a laxative effect at higher intakes than pure bisglycinate. If you’re taking a bisglycinate product specifically because other magnesium forms upset your stomach, a blended product may partially reintroduce that issue.
Which alternative is actually 100% pure bisglycinate?
Of the options we checked, Natural Factors’ PURE powder line (verified: “Magnesium (bisglycinate) 200mg” with no oxide listed) and AOR’s Magnesium Glycinate (verified: “100% pure magnesium glycinate,” no oxide) are both confirmed oxide-free. Don’t confuse Natural Factors’ PURE line with their regular capsule line, which uses the same buffered blend as Webber.
How much magnesium should I actually be taking?
Health Canada’s recommended intake (from all sources, including food) is 400-420mg/day for adult men and 310-320mg/day for adult women. The tolerable upper limit from supplements specifically is 350mg/day, food-sourced magnesium doesn’t count toward that limit. A single 200mg capsule is a meaningful supplement, not necessarily your entire requirement.
Does Webber Naturals ship outside Canada?
This specific affiliate program and product line is Canada-focused. If you’re outside Canada, the Natural Factors, AOR, or NOW Foods alternatives above are more broadly available internationally.
