TikTok Shop's best-selling magnesium puts 500 mg in one NSF contents-certified capsule, but oxide leads an undisclosed 8-form blend and the dose tops NIH's limit.

Pros and cons
High Absorption Magnesium (Lysinate Glycinate)
- Fully chelated magnesium lysinate glycinate made with Albion TRAACS
- Clear elemental dose: 200 mg per two tablets
- Vegan, gluten-free, soy-free and non-GMO
- About $0.20 per 200 mg serving
- The label's full dose (400 mg) exceeds the 350 mg upper limit for supplemental magnesium
- Large tablets that some people need to split
- No USP or NSF certification
- Grogginess or loose stools reported by some at the full dose
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
High Absorption Magnesium (Lysinate Glycinate)
A well-tolerated, clearly labeled chelated magnesium at a fair price, and a sensible first choice for people who found magnesium oxide or citrate hard on the stomach. Start with one 200 mg serving rather than the label's full 400 mg, and expect large tablets.

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.
