Magnesium and Cholesterol
A straight answer on magnesium and blood lipids — what's known, what isn't, and why nothing on this page is an alternative to cholesterol medication.
We'll open with the most important sentence on this page.
If you have been prescribed medication for your cholesterol, take it. Do not replace it with magnesium, or with any other supplement, mineral or wellness product.
The Dutch-language page this article replaces positioned magnesium as a natural alternative to medicines "that often cause side effects." We've removed that framing entirely, and we want to be explicit about why: statins have decades of outcome data showing they reduce heart attacks and strokes. Swapping one for a bath product is a trade with real consequences, and no one selling minerals should be encouraging it.
WHAT CHOLESTEROL ACTUALLY IS
A fatty substance your body needs, for cell membranes, hormones and vitamin D synthesis. Most of it is made by your liver rather than eaten, which is why dietary cholesterol turned out to matter less than was assumed for decades.
It travels in lipoproteins. LDL deposits cholesterol in artery walls. HDL carries it back to the liver. High LDL over time contributes to plaque; that's the mechanism connecting a blood test to a heart attack.
Triglycerides are a separate fat, tracked on the same panel, and they respond strongly to alcohol, refined carbohydrate and weight.
WHAT'S KNOWN ABOUT MAGNESIUM AND LIPIDS
Less than you'd guess from the internet.
Magnesium is involved in enzyme systems across metabolism, including some involved in lipid handling. That's mechanism, not outcome.
Studies of magnesium supplementation and blood lipids exist and have produced mixed results. Some show modest changes in some markers, others show nothing. This has not converged into a recommendation from any cardiology body.
For context, the NIH's assessment of magnesium and cardiovascular disease broadly is that evidence is limited and inconsistent, and the FDA's qualified health claim on magnesium and blood pressure explicitly describes the evidence as inconsistent and inconclusive.
There is no evidence that magnesium applied to skin affects cholesterol. We're not aware of a single study that even asks the question.
WHAT ACTUALLY LOWERS LDL
Prescribed lipid-lowering therapy where indicated. It's the intervention with outcome data behind it.
Dietary change with real substance to it: more soluble fibre from oats, beans and barley, replacing saturated fat with unsaturated, more plants, less ultra-processed food.
Physical activity, which does more for HDL and triglycerides than for LDL, but does plenty.
Stopping smoking, which changes cardiovascular risk regardless of what the lipid panel says.
Weight management where appropriate.
Notice that the diet described there is magnesium-rich almost by accident. Beans, oats, nuts, seeds, leafy greens. That overlap is probably part of why observational studies keep finding associations.
THE NUMBERS TO ASK FOR
A full lipid panel: total cholesterol, LDL, HDL, triglycerides. Plus a cardiovascular risk assessment, because an LDL number in isolation means less than an LDL number alongside your blood pressure, age, smoking status and family history.
If you've got a family history of very high cholesterol or early heart disease, mention it. Familial hypercholesterolaemia is more common than most people realise and it's substantially underdiagnosed.
MAGNESIUM'S HONEST ROLE HERE
As a nutrient in a good diet. Target 400–420 mg a day for men, 310–320 mg for women, mainly from food.
That's it. That's the claim.
WHERE OUR PRODUCTS FIT
They don't, for cholesterol. They're bath and body products.
If you want a magnesium bath after a walk you took because your doctor told you to move more, that's a good evening. It isn't a lipid intervention, and we won't sell it to you as one.
