Magnesium and Regenerative agriculture
A deep dive into what magnesium does for our bodies, why we are deficient and need to supplement while actively supporting shifting agricultural practises for the betterment of both humans and land.
Here are 10 key ways your body uses magnesium—vital for 300+ reactions.
1. Powers energy: Turns food into ATP fuel.
2. Relaxes muscles: Prevents cramps & spasms.
3. Calms nerves: Supports mood & sleep. Activates the 'switch off' arm of nervous system
4. Builds bones: Pairs with calcium, manganese, copper, vitamin D & phosphorous for strength.
5. Steadies heartbeat: Regulates rhythm.
6. Boosts DNA: Aids repair & synthesis. Genes are not set in stone
7. Balances blood sugar: Improves insulin sensitivity along with herbs such as gymnema, bitter melon, cinnamon, barberry and nutrients such as chromium and manganese
8. Eases stress: Activates relaxation pathways.
9. Strengthens immunity: Fuels enzyme defences
10. Supports detoxification: Helps liver & kidneys flush toxins.
How Western Australia's Soils Might Lose Magnesium—and What It Means for Your Plate
Western Australia's vast agricultural lands, from sandy coastal plains to the wheatbelt's ancient, nutrient-poor soils, are prone to magnesium (Mg) depletion. This isn't just a farming issue—it can trickle down to lower Mg in local produce like grains, veggies, and meats, potentially contributing to the fact that 1 in 3 Australians don't hit their daily Mg needs (around 310-420 mg for adults).
Here's a breakdown of key mechanisms, drawn from soil science and agricultural research:
Crop "Mining" Through Harvests
Intensive farming of wheat, barley, canola, and pastures removes Mg in harvested grain and fodder—up to 30-40kg MgO/ha per crop cycle. Without balanced fertilizers, soils get "mined" over time, especially in high-yield systems. WA's wheatbelt, producing ~40% of Australia's grain, amplifies this.
Leaching in Sandy, Acidic Soils
WA's light-textured soils - coastal dunes or southwest sands—let Mg wash away with winter rains. Acidic conditions (pH
