Frequently Asked Questions
Some magnesium supplements list a higher potency because they include a blend of different magnesium types, including ones that may not absorb as well (like Magnesium Oxide). The number on the label often refers to “elemental magnesium”, which is the total amount of magnesium regardless of how it's delivered.
Jamieson 100% Pure Magnesium Bisglycinate delivers 100 mg of magnesium from a single, well-absorbed source—so you're getting a consistent, gentle, and effective dose your body can use.
Both terms are often used interchangeably, but Magnesium Bisglycinate is the more scientifically accurate name for the form of magnesium that’s bound to two molecules of the amino acid glycine (hence the prefix "bis-"). This specific structure helps improve magnesium’s absorption and can make it gentler on the stomach compared to other forms.
Some products labeled “Magnesium Glycinate” may actually be referring to Magnesium Bisglycinate, but it’s always a good idea to check the label or consult the brand to confirm the exact form used.
Magnesium Bisglycinate is often chosen for its high absorption and gentle digestive profile. It’s a form of magnesium that’s bound to glycine, an amino acid, which helps it pass through the digestive tract more easily and be better absorbed by the body.
Other forms of magnesium—like Magnesium Oxide or Magnesium Citrate can be harder on the stomach and may not be absorbed as efficiently. However, the best form for you depends on your individual needs and how your body responds.
Yes, Magnesium Bisglycinate is commonly used as a daily supplement. It’s known for being well-tolerated, even by those with sensitive digestion. As with any supplement, it’s best to follow the recommended dosage on the label and consult with a healthcare practitioner if you have any specific health concerns or are taking other medications.
