Yogourmet freeze dried yogurt starter is one of the best starters on the market. It is great for making SCD yogurt, and it can be used with both cow's or goat's milk and vegetal milk. For vegans, and for lactose intolerant, note that the product contains milk powder, though the milk powder is in a very low quantity.
The starter also contains a little sugar, that's what makes the starter more efficient, and it is not a concern for diabetics, because of the very low dose.
The starter contains Lactobacillus Bulgaricus, Streptococcus Thermophilus, Lactobacillus Acidophilus, for a perfect balance of probiotics, and for a great tasty yogurt.
