白澤 5 Switched to this brand from another, after I had some unwanted side-effects with the other brand. These ones were really easy to swallow when my morning sickness was bad, and you only have to take one pill each day. I am now 25-weeks pregnant and have moved onto the next Pigeon pregnancy supplements which include calcium. I'll only use and recommend this brand I think - easy to swallow, handy little pill container, good price on Amazon, renowned brand.
