Garden of Life Primal Defense HSO Formula powder is one of 4 different probiotic supplement formulations in the Primal Defense family. Since the formulations are significantly different enough, this review is for the HSO powder one, and not the ULTRA, CAPLETS or the KID’s formulas. This probiotic supplement is marketed to be “the only probiotic formula that contains a unique whole food blend with Homeostatic Soil Organisms (HSOs).”
It is also marketed to be "a unique broad-spectrum probiotic powder, designed to deliver 12 species of beneficial cultures including Homeostatic® Soil Organisms, including 1 Billion CFU of Bacillus subtils plus Lactobacillus and Bifidobacterium probiotics to promote regular bowel function and immune system health."
The HSO blend "helps promote healthy digestive balance, support normal absorption and assimilation of nutrients, and help maintain a healthy immune system.
This supplement contains 12 species of microbes in the form of their HSO Probiotic Blend. Garden of Life stated, “The HSOs in Primal Defense are important probiotics you would get in abundance if your food came from soil untouched by pesticides, herbicides and other widely used chemicals.” But what are HSOs?
Homeostasis is the tendency of something to maintain a condition of balance or equilibrium, such as the way your body is able to maintain a rather constant internal temperature of 98.6 degrees F no matter what the environmental temperature (within reason, of course.) A Homeostatic Soil Organism, then, is an organism which is from the soil and which maintains homeostasis. Garden of Life actually trademarked the phrase, as it has no real relevance in scientific terms. While some of their microbes may in fact be sourced from soil, there is no significance to their term.
Their proprietary HSO blend in Primal Defense HSO Formula consists of barley grass, oat grass and the following microbes:
Bacillus subtilis, 1 billion
and enzymes from S. boulardii.
There are four forms of this supplement, powder, kids'powder, capsules (Ultra) and caplets. The adult products seem to have the same species but in different orders, so no conclusions can be generally drawn about all of the products..
Other ingredients as of February 2018 are:
Please verify ingredients of any supplement prior to taking it.
For the powder and the caplets, the suggested use is for adults to take 1 scoop (1/3 teaspoon) OR 1 caplet 3 times per day with 8 ounces of water or juice, preferably on an empty stomach. It is recommended to begin with 1 scoop per day and gradually increase to the suggested amount.
The pros of this probiotic supplement as I see them are:
Some positive reviews, with 4.8 out of 5 stars from 97 reviews, from the Vitacost.com website stated:
“I ran out of this product and decided to try another probiotic for a change. I bought one at a local store. After a few days my old digestive problems (bloating, indigestion, nausea) returned despite taking the probiotics as directed with every meal. So, I hurried re-ordering this product from Vitacost. I'm so glad I found Garden of Life Primal Defense. Taking one a day in the morning on an empty stomach makes all the difference for me! Will stick with it for sure!” 11/17/15
“I love this! I was terrified to travel due to having to hurry to the bathroom when it was time and if not close enough, having a disaster happen. So embarrassing. Primal Defense has helped tremendously, granted it does not cure, but it certainly has made my situation livable within days and getting even better in less than 30 days!!” 11/2/15
“…I added it to my general health and fitness regimen some time ago and noticed that it helped combat my histamine-response (versus anaphylactic) food allergies. Since then, it has become one of my primary methods of preventing those reactions…” 2/10/16
The cons of this probiotic supplement as I see them are:
The negative reviews totaled 6% on Amazon.com and featured reviews like these:
“The product states it is gluten free, however it contains barley and oat grass, which can be gluten free, but if there are seeds present it will absolutely contain gluten. This product made me sick for weeks until I finally figured out what I was consuming that contained gluten, after reading other reviews.” 2/17/12
“They gave me a rash. If they did anything else I have no idea. I sent them to the friend that said he used the product, but it is not the one for me.” 6/13/14
“These are very large hard pills (tablets) not capsules (caplets) at all. I was very disappointed. I was getting much better results from eating yogurt daily than from these. It is past the time frame for return or I would do so in a heartbeat. I will never buy these again. Additionally, after starting to take these pills I started to have neurological issues. Issues such as dizziness, cognitive issues, ringing in my ears, migraines, and much worse…” 5/14/15

If you would like help in determining if Primal Defense HSO Formula is right for you, please consider nutritional consultations with me. A supplement is just that: supplemental to other healthy lifestyle factors. A supplement should not replace good eating habits and taking care of oneself and nutrition consultations can certainly help with those.
Garden of Life has some very good products, but this may or may not be one of them. While many folks have success with Primal Defense HSO Formula, others seem to not just have no improvement in their conditions, but have adverse reactions. Please exercise caution with this supplement if you have allergies or sensitivities to wheat, gluten, milk or soy, or if you have any disruption in the health of your small intestine (celiac disease, Crohn’s, etc.)
