Biogena Magnesium Bisglycinate 125

Product description
Magnesium Bisglycinate 125 is a focused magnesium single-ingredient product providing 250 mg of magnesium per daily dose exclusively as bisglycinate. The product character therefore lies in one clearly defined compound and a medium supplemental dose rather than in a blend of different magnesium forms. From an orthomolecular perspective, this makes magnesium intake easy to calculate; other magnesium supplements and dietary sources should still be included in the total.

Micronutrient knowledge
Micronutrient knowledge
Physiological functions, notes on high or insufficient intake and relevant interactions — presented separately from the specific product assessment.
Magnesium
Magnesium is an essential mineral involved in numerous enzymatic reactions. For product assessment, the manufacturer’s dosage, active-ingredient forms and reference values are considered separately.
Functions
Magnesium contributes, among other things, to normal muscle and nerve function and to normal energy-yielding metabolic processes. It is also involved in processes related to protein, bone and DNA.
Possible signs of insufficient intake
Insufficient magnesium intake can present with nonspecific symptoms; possible indications may include neuromuscular complaints. Individual symptoms do not establish a diagnosis and should not be assessed in isolation.
Points to consider at high intake
High amounts from supplements can mainly cause gastrointestinal symptoms such as diarrhoea, nausea and abdominal cramps. With severely impaired kidney function, the risk of magnesium accumulation increases; high doses should then be medically assessed.
Special considerations
With impaired kidney function, magnesium excretion is reduced. Product dose, magnesium form, tolerance and total intake should therefore be considered separately.
Interactions / caution
Magnesium can affect the absorption of certain medicines, including some antibiotics and bisphosphonates. Timing intervals and individual medication should be reviewed with regular use.
Scientific assessment
Studies, meta-analyses and randomized controlled trials on the active ingredient – explained clearly and linked to sources.
