I can now report that taking large daily doses of Magnesium 'Oil" has resulted in much less muscle pain.
I noticed a benefit after a week, but waited to see if it would sustain.
Now, 3 weeks later, I am so much better in this respect.
I take 2 teaspoons of it through the day in water. It has a slightly bitter taste.
I originally took the magnesium powder on a chemist's advice, then changed to the stronger capsules, but have to say I noticed no benefit from either.
However, the Magnesium Chlorate Oil has been totally different.
It is called an oil as some say it has an oily feel when rubbed on the skin-the best way for absorption, but too much of a nuisance for me.
It is really just concentrated deep sea water, full of minerals.
I read that it is estimated that 70% of people are magnesium deficient, and so may be suffering muscle pains as a result.
For anyone in that position, I can honestly recommend this supplement.
You take the max dose until you get the benefit, then drop down to a small dose.
