60 capsules - Ideal daily dose for steady magnesium support.

Benefits & Features:

• Steady magnesium release supports day long vitality.
• Immediate citrate absorption provides quick support when you need it most, without a long wait.
• Extended release reduces gastrointestinal upset compared with quicker dissolving forms, promoting better tolerability.
• Designed for daily use with or without meals, a hallmark of this magnesium dietary supplement.
• Dual release delivers steady magnesium levels throughout the day, supporting cardiovascular function, bone health, metabolic balance and overall comfort, daily energy, and wellbeing.

Life Extension has a long standing heritage of quality, backed by LE Certified standards and GMP control. The extend-release design uses ZümXR magnesium oxide for sustained delivery paired with magnesium citrate for instant absorption, helping maintain steady magnesium levels. This magnesium dietary supplement focuses on practical daily wellbeing rather than aiming to be a vitamin d supplement, and some shoppers compare magnesium glycinate options, delivering reliable support for cardiovascular function, bone health and metabolic balance.
