As much as some mothers would like to breast feed their babies, in many cases it is not possible or the need for supplemental milk is required.  Below is a summary of where to buy (at present) the most natural and highly rated infant formula Holle, a Swiss brand, and have it shipped to the US.  If you have information on where to buy this from other countries, please comment and I will update the post with your links and information. You can also visit the Holle website that lists current retailers by country.

>> For details and ingredients about Holle formula, see my other post here.

I will start out that these recommendations are researched, and not for the readily available organic, off-the-shelf brands like Earths Best, Walmart's Parent's Choice or Similac Organic.  There are reference articles and testimonials at the bottom of this post, so please educate yourselves as to what you are feeding your babies, if not to tell other mothers and caregivers what should *not* be in our infant formulas available in the US.
