withinUs Magnesium L-Threonate with Magnesium Bisglycinate L-Theanine and Marine Collagen, Raspberry or Lemon, Jar or Sticks

withinUs Magnesium L-Threonate Details

A drinkable magnesium pairing magnesium L-threonate with magnesium bisglycinate, plus L-theanine and marine collagen. Raspberry or lemon, as a 14-serving jar or a box of 14 sticks.

Magnesium L-threonate is the reason this costs what it does. It is a specific magnesium salt, considerably more expensive per milligram than the citrate or oxide forms that fill most magnesium products, and it exists because of research into how well different forms cross into the central nervous system. This product carries no NPN in the supplier record, so no approved Health Canada claim attaches to it and none is made here — what you are buying is the form, not a licensed outcome.

Pairing it with magnesium bisglycinate is a sensible formulation choice. Bisglycinate is magnesium bound to glycine: well absorbed and much gentler on the gut than oxide, which is where magnesium gets its reputation for loose stools.

L-theanine is the amino acid found in tea leaves, associated with a calm-but-alert state rather than sedation. The marine collagen is the withinUs house base, present across the whole range.

The jars are 146g in raspberry and 137g in lemon — different grams, same 14 servings, matching the 14-stick boxes. Flavour density is what changes, not the dose.

withinUs is a Canadian company built around TruMarine collagen, sourced exclusively from the scales of wild-caught fish rather than from hides or bones.

Who withinUs Magnesium L-Threonate Is For

This suits anyone who has specifically looked into magnesium L-threonate and wants that form, and anyone building an evening wind-down routine who would rather drink a magnesium than swallow capsules. The sticks travel; the jar is better value at home.

Contains fish — unsuitable for a fish allergy, and not vegan or vegetarian. This product carries no NPN in the supplier record and therefore no approved health claim. Consult a practitioner before use if you are pregnant or breastfeeding, have kidney disease, or take any medication — particularly sedatives or blood pressure medication, since both magnesium and L-theanine can add to those effects. Magnesium can cause loose stools; start low.
