Triquetra Plant Magnesium – Whole Food Magnesium – 60 Capsules
Triquetra Plant Magnesium is a whole-food, plant-based magnesium supplement providing 250mg of naturally occurring magnesium per daily serving from organic sea vegetables.
Made with a mineral-rich complex of Organic Sea Lettuce, Organic Irish Moss and Organic Bladderwrack, Plant Magnesium offers an alternative to conventional isolated magnesium supplements.
The sea vegetables naturally provide magnesium alongside other mineral co-factors and whole-food compounds, creating a simple, food-derived approach to everyday mineral support.
Whole-Food Magnesium
Magnesium is an essential mineral involved in hundreds of processes throughout the body and is particularly important for muscle function, energy production, nervous system function and bone health.
Triquetra takes a different approach to magnesium supplementation by sourcing its magnesium from mineral-rich sea vegetables rather than using a single isolated magnesium compound.
Each 2-capsule serving provides:
Magnesium – 250mg
from organic sea lettuce and an organic sea vegetable complex.
Sea Vegetable Mineral Complex
Each daily serving also contains 1,120mg of organic sea vegetables, including:
Organic Sea Lettuce
Organic Irish Moss
Organic Bladderwrack
Sea vegetables naturally absorb minerals from their growing environment, creating a naturally occurring matrix of minerals and other whole-food compounds.
Triquetra describes this as its Food Matrix Enhanced approach – providing magnesium within the broader nutritional matrix naturally found in the plant source.
Muscle + Nervous System Support
Magnesium contributes to normal muscle and nervous system function.
This makes adequate magnesium particularly relevant for those wanting nutritional support for:
Normal muscle function
Nervous system health
Everyday relaxation
Physical recovery
General wellbeing
Rather than positioning Plant Magnesium purely as a nighttime supplement, its broad physiological role makes it suitable for everyday mineral support.
Energy + Vitality
Magnesium also contributes to normal energy metabolism.
Because of this, magnesium requirements are relevant not only to relaxation but also to maintaining normal cellular energy production and everyday vitality.
Plant Magnesium can therefore be incorporated as a foundational mineral supplement for those wanting to support both energy and relaxation.
Bone + Mineral Health
While calcium often receives the most attention when discussing bone nutrition, magnesium also contributes to the maintenance of normal bones.
Triquetra Plant Magnesium provides magnesium alongside the naturally occurring mineral co-factors found within its sea vegetable ingredients, making it particularly appealing for those who prefer food-derived mineral supplementation.
Organic Sea Lettuce From France
The Sea Lettuce used in Plant Magnesium is organically farmed in France.
Triquetra specifically selects sea vegetables for their natural ability to accumulate minerals and uses them as the foundation of this whole-food magnesium formula.
