Susu Kambing Merah or Red Goats Milk in English is widely available in Malaysia. It contains 90% dried goats milk with 10% red fruit. There are no other additives - especially Soy based ingredients which means that the milk is safe for babies with G6PD deficiency.
Goats milk is apparently easier to digest and less fatty than cows milk. Also according to the pack, it's high in nutrients such as riboflavin and vitamin B2 which apparently are good for enzymes and red blood cells. This could be an added bonus for babies with G6PD deficiency.
How does it taste? Not as good as breast milk! It is drinkable though and should still go down fine in moderation. My baby girl drinks it as a supplement when breast feeding is not convenient but I don't think she would like it all the time! Just remember though if your baby has G6PD deficiency that a breast feeding mother must also follow a strict diet and not eat any of the disallowed "trigger" foods or medications because they can be passed to the baby via breastfeeding and cause the condition to worsen.
As far as I know this product is only available in Malaysia, but abroad you can probably find simliar powdered goats milk products. Here the goats milk sells for about RM 68.00 for 300 grams. That's about US$20 a pop.
