Lactose pills is just what your own body use to produce to help you digest milk - and enzyme Lactase.
Your body used to produce this enzyme - and not anymore. that is why you can't digest milk anymore.
That's why they invented it in a pill and liquid form to be taken orally.
It is NOT the same as for example pain or cold medication.
Just because it is manufactured outside of your body doesn't means is "unhealthy".
On the contrary,- it helps you digest milk which otherwise is not fully digested so the benefit of drinking milk is not whole.
Think of it like this- (it's just an example) - to digest all the food you eat your stomach needs "stomach acid".
For some reason your body stopped producing this acid and you can't digest your food properly anymore. you feel sick, gassy and bloated, the nutritions from the food is partly wasted.
Luckily they invented "stomach acid" in pill form. Is the same as your body used to make.
Once again your stomach can digest the food as it should.
(remember it's just an example to illustrate how body's things work, meaning there is no real "stomach acid" and "acid pills")
So, go get this Lactaid pills and drink the milk you love.
