Sports Research FG441 Magnesium Glycinate, 160 mg, 90 Veggie Capsules
Product description
Some shoppers want a magnesium supplement for a nighttime routine, others prioritize the form of magnesium in each serving. Sports Research FG441 combines magnesium glycinate with a chelated formula. The veggie capsules offer a straightforward way to add this form to a supplement routine. The formula is also soy-free, gluten-free, and IGEN non-GMO tested.

Chelation is the defining feature of this formula. The manufacturer describes the process as attaching amino acids to minerals to support absorption. That makes this option relevant for shoppers comparing magnesium forms who specifically want chelated glycinate rather than a non-chelated formula. The stated amounts distinguish the magnesium content from the amount of chelated magnesium glycinate per serving.

Tips for day-to-day use
The 90-capsule bottle suits shoppers who prefer a capsule format for a regular supplement routine. For a routine centered on winding down, the product is positioned to support relaxation and restful sleep, making its intended use easy to understand without relying on a complicated blend of ingredients. Follow the product label for serving directions as you incorporate it into your routine.



If you are comparing magnesium supplements, consider whether the form matters to you: this formula uses chelated magnesium glycinate, while other options may use non-chelated forms. The manufacturer highlights chelation as a way to support bioavailability. Its soy-free and gluten-free formulation, along with IGEN non-GMO testing, also gives shoppers specific dietary and sourcing details to consider when choosing a supplement.
Everyday use

For someone adding a supplement to an evening wind-down routine, the capsule format and sleep-support positioning make the product a clear fit for that use. The formula is designed around magnesium glycinate, not a broad mix of unrelated ingredients, so the main point of choice is its chelated form and stated magnesium amounts. It makes sense if you are looking for a veggie-capsule magnesium glycinate supplement with a clearly identified daily-routine role.


Customer feedback commonly highlights sleep and relaxation, and some buyers also appreciate the capsule’s ease of use. Experiences with digestion are mixed: some customers describe it as gentle, while others report stomach discomfort. These are individual experiences, not a promised result, and may help shoppers weigh how the supplement fits their own routine.

Buying verdict

Sports Research FG441 is suited to shoppers seeking a chelated magnesium glycinate supplement in veggie capsules, with a formula positioned for relaxation and restful sleep. Its 160 mg magnesium amount, 1,441 mg chelated magnesium glycinate per serving, and soy-free, gluten-free formulation provide concrete details for comparing options. Choose it when those features align with the kind of magnesium supplement you want to add to your routine.
