Benefits & Features:

• Supports muscle and bone health quickly and easily.
• Three forms - oxide, citrate, and aspartate - work together for better absorption.
• Daily capsule fits into a busy routine and is easy to swallow.
• Three forms deliver magnesium in a way the body can use more readily, helping you feel steadier during long days, supporting calm mood, and reducing fatigue when daily intake is insufficient.
• Pairs well with a vitamin d supplement, making it a practical addition to a daily wellness routine.

Swanson's triple magnesium complex uses three forms - oxide, citrate, and aspartate - for broad absorption, and while some people reach for magnesium glycinate for absorption, this blend aims to cover daily needs.

The formula fits easily into everyday routines and can pair with creatine or a vitamin d supplement for a simple wellness habit.

The Core Ingredient Is: Magnesium (oxide, citrate and aspartate)

Magnesium is a vital mineral that helps with normal muscle, bone, heart, and nervous system function.

This blend combines oxide, citrate, and aspartate forms of magnesium to help daily mineral balance and maximise bioavailability.

What Does Magnesium Do?

Magnesium helps keep muscles working and supports bone mineral density, while also supporting heart and nervous system processes.

Dr Castiglioni from the University of Milan found that magnesium supplementation can boost bone mineral density, underscoring its part in skeletal health and overall mineral utilisation.
