You're welcome. Yes, you can split tablets/capsules into whatever dose you require.

Most people starting with detoxing mercury start with 12.5 mg. Seems to be the best dose to begin with. 25 mg is ideal if you can get DMSA that low and simply split the dose in half into 12.5 mg.

I used to put the other half back into the capsule and save it for one of the night doses, so I'd not have to wake up and split capsules. I'd just split during the day and take the first half of the powder then and there and again put the remainder back into the capsule as another night dose.

But people have their own ways of doing it.
