Milk based micro-nutrient supplement for pregnant and lactating women

I would like to find out if anyone has any experience of a macro- and micro-nutrient supplement for pregnant and lactating women. We are looking at supporting the development of one that is milk-based and would like to learn from anyone's experience. Thank you.

Arvind, thank you for your reply. We were hoping to get guidance on how much to supplement in terms of macro- and micro-nutrients based on what is currently recommneded best practice. Any experinece / advice is most welcome. Thank you.
