Pros and cons
Magnesium (Glycinate)
- Minimal formula: magnesium glycinate, a cellulose capsule and ascorbyl palmitate
- GFCO certified gluten-free, vegan and free of common allergens
- Flexible 120 mg capsules make dosing easy
- Detailed in-house and outside lab testing disclosures
- About $0.30 per 120 mg capsule, pricier than many glycinates
- The four-capsule maximum (480 mg) exceeds the supplemental magnesium upper limit
- No USP or NSF certification
- Capsules are fairly long at 0.905 inches
Magnesium Complex
- Listed under NSF/ANSI 173 contents certification, so label accuracy and contaminants are independently checked
- One capsule a day, and a 90-count bottle lasts three months
- About 33 cents per capsule at the brand's current price
- Short excipient list: a vegetable capsule, a standard filler and flow agents, with no colors or sweeteners
- Buyers frequently report calmer evenings and fewer muscle cramps within two weeks
- Amounts of the eight forms are not disclosed, and poorly absorbed magnesium oxide is listed first
- 500 mg per capsule exceeds NIH's 350 mg upper limit for supplemental magnesium, raising the odds of loose stools
- Large capsules that some buyers find hard to swallow
- Counterfeit listings and look-alike sites using the Toplux name describe different formulas
Our verdicts
Magnesium (Glycinate)
This is the cleanest, most allergy-friendly magnesium glycinate you can easily buy, with unusually detailed testing disclosures and a formula that is kind to sensitive stomachs. You pay a premium for that, so budget buyers can get similar magnesium for less, but for people who react to fillers or other forms it is worth the money.

Magnesium Complex
Toplux earns its NSF contents certification, and one capsule a day is easy, which helps explain its loyal following. The eight-form story is mostly marketing, though: amounts are undisclosed, oxide leads the list, and 500 mg exceeds the supplemental upper limit. If you want a gentle, well-absorbed magnesium for sleep or stress, a glycinate or citrate product with a disclosed dose is the better buy; if you tolerate magnesium well and value the certification, Toplux is a reasonable but overhyped choice.
