Why do a lot of your products contain high amounts of vitamin B6 ( Pyridoxine hydrochloride) ? , Much higher than the recommended daily intake and at levels that if used over a long period of time could possible cause nerve damage
How come I can buy your own product cheaper at Chemist Warehouse - 200 tablets for $26.99? Seems ridiculous to me!
Is this product okay for those with sulphite/sulphur reactions?

Can I take this along with a multi vitamin and a hair,skin, nails supplement?
I have accidently taken two tablets in one day, will this cause any harm?
Can this tablet be crushed? I find it difficult to swallow.
Hi, Can you create an Mg product for elderly but reduce or even completely remove the B6 component so that the product is safe to use every day indefinitely? There are warnings about prolonged daily use of B6 since it comes with side effects.
Is this the same as Super Magnesium+? Ingredients seem to be the same
