If the muscles are what is crushing your bone on bone knee joint — the question becomes simple.
What actually reaches muscles?
The answer is magnesium.
Here is why that matters.
Magnesium is the mineral your body uses to make muscles relax. Think of it like an off switch for muscle tension. When your body has enough magnesium a tight muscle can receive the signal to let go.
But when your body is deficient in magnesium that signal never arrives.
And research shows that over 70% of adults over 50 are magnesium deficient.
Which means the muscles wrapped around your bone on bone knee joint — already being told to tighten permanently to protect an unstable joint — cannot fully let go even if they wanted to.
Because the mineral that tells them to let go is not there.
Now here is the problem with magnesium supplements.
When you swallow a magnesium pill it goes through your digestive system first. Your body then distributes it through your bloodstream to wherever it is needed most urgently. Your heart. Your brain. Your nervous system.
By the time any of it reaches the muscles around your knee joint most of it has already been used up elsewhere.
Which is why magnesium pills do not work for bone on bone knees. Even if you have never tried them. Even if you have and noticed nothing.
The delivery method is the problem. Not the mineral.
The right delivery method is through the skin.
When magnesium is applied directly onto the skin above the knee it absorbs straight through into the muscle tissue underneath. It bypasses the digestive system and the bloodstream entirely. It goes straight to where it is needed.
The same principle behind nicotine patches. The same principle behind hormone patches for menopause. Delivering something directly through the skin to the tissue underneath.
But not all magnesium absorbs through the skin equally.
Magnesium oxide — the form found in most cheap supplements and sprays — has an absorption rate so low through the skin it barely enters the body.
Magnesium chloride is different. It absorbs at a significantly higher rate through the skin. It has been used in clinical and medical settings for transdermal delivery for decades.
That is the form that actually reaches the muscles.
