I would check out google shopping or buy.com for places that you can buy these probiotics. Another one you could try to search for is HMF Neuro or HMF forte which are the only probiotics that use human micro flora in it.
If you cannot find the ones we recommend, taking any one with DDS-1 is OK. Also, if you want to, rotating the brands of probiotic is definitely recommended. This will allow your gut to have quite a variety of flora (kefir does this also).
The only problem with the probiotic you have shown us is that it contains only 600 million probiotic per serving and you need 30-50 billion or so per day if possible. At the least, I would search for one’s that contain 30 or 50 billion and get one with atleast 12 strains. Renewlife is an example of one that has this.
