Questions & Answers

Q. What is the difference between the human health products?

Rawbiotics: Rawbiotics is our range of human health products. Rawbiotics are live fermented probiotics. Unlike pure-culture (freeze-dried) probiotics, Rawbiotics contain 12 strains and multiple classes of live beneficial bacteria, fermented at body temperature. As a result, users end up with a comprehensive probiotic that survives stomach acid better than most probiotic brands. Rawbiotics contain the same beneficial probiotics that are in our old range of products (Probiotica, Health Booster and Health Booster Extra Strength), but the Rawbiotics products are manufactured using a new range of organic fruit-juices, giving the products an improved taste, and also with the addition of select herbal extracts to better tailor the products to specific users offering our customers a superior product. They are available in 500ml and 1 litre bottles as 3 different product offerings: DAILY, KIDS & GUT.

RAWBIOTICS DAILY: A daily probiotic that restores the natural bacteria needed for optimum health.

RAWBIOTICS KIDS: A daily probiotic that provides natural bacteria needed for children’s health and growth. These essential bacteria improve the body’s ability to use nutrition, assisting with healthy growth and increasing the body’s ability to create natural vitamins and antibiotics. 

RAWBIOTICS GUT: A probiotic that works to correct imbalances that lead to digestive disorders such as IBS, bloating, acid reflux, diarrhea and constipation and restores long-term healthy balance to the gastro-intestinal tract. 

Q. Are there any side effects?

Very seldom. Occasionally the body may start to detox and get rid of chemicals which have been in your system, resulting in mild diarrhea or gas. If this occurs too suddenly, just cut down quantity and increase slowly until the body is comfortable with it. Any side effects experienced will be as a result of the detox action of the beneficial bacteria. This is a good thing as it shows the body is cleansing itself.

Q. How much should I take if I have a compromised digestive system?

Everyone has a different ratio of microbes in their digestive tract.  Our product contains anti-oxidants in large numbers, as well as very active beneficial bacteria. Individuals with compromised immune/digestive systems MUST start on lower dosages: for adults: 1 tablespoon (15ml) per day, and for children under the age of two, 1 teaspoon (5ml) per day. After a month one can start slowly increasing the dosage.


Q. When should you take the probiotic?

Efficient Microbes probiotics can be taken at anytime. With or without meals, morning or evening. Just make it part of your daily routine in order to never miss your dose. 

Q. How do your products differ to other probiotics?

The reason for Efficient Microbes efficacy and results is not, as many people believe, the number of microbes present in the product but, rather the number of microbial species. Although lactic acid bacteria are the most predominant bacteria in the GI tract they cannot establish themselves without the natural symbioses they share with other types of microbes. In the natural world various classes of bacteria are utterly reliant upon each other for growth and stability, as can be seen by the diversity of microbial life in soils and plants. Unlike most probiotic products which contain freeze-dried strains of just one or two species of microbes, Efficient Microbes closely mirrors the natural range of microbes that are found in our soils and food. It is the combination of these species which make Efficient Microbes unique. This is what accounts for their efficacy and successes.

Q. Why are Efficient Microbes Products unique?

The reason that we consider our product superior to other bacterial or probiotic supplements is simply that unlike most biological products available, Efficient Microbes is made up of three classes and multiple strains of bacteria, as opposed to the usual single-class bacterial products. The product is brewed at body temperature and stable at room temperature. It is completely raw and natural. One of the major benefits is that it not only consumes toxins and eliminates pathogens, but also, through its extremely powerful probiotic qualities, promotes health and life. Thus, it is also used widely in the fields of waste treatment, agriculture and livestock (our other lines of business in South Africa). Efficient Microbes technology is one of the only technologies on the planet that allows for a variety of different classes of bacteria to be grown and maintained stably in a probiotic consortium.

Q. The bacterial count (CFU) of Efficient Microbes is lower than other probiotics, why?

The questions of bacterial counts (more commonly referred to as the CFU count – Colony Forming Units) and survivability in the GI tract is really only relevant when one is dealing with pure cultures i.e. those strains are grown in isolation. Pure cultures are generally very weak and have very little resistance or adaptability. Very high counts are therefore essential in order to get a fraction of the dose to survive the stomach and GI tract. Generally AB (Acidophilus/Bifido) culture probiotics have CFU counts in the billions. These are often freeze dried or dehydrated which further reduces their efficacy. They are also sometimes inserted in “carrier” mediums in order to “shelter” them from the low ph. stomach acid. An analogy would be taking a child and protecting him/her from any and all illnesses during the initial 2 years of life. As soon as that child is exposed to the real world you can expect him/her to contract numerous illnesses as there is very little resistance that has built up; the immune response has not developed.

Conversely, the microbes in Efficient Microbes are composed of a wide ranging consortium of multiple strains and classes. They are not grown in pure culture and therefore have to compete with each other in order to survive and proliferate. This far more closely approximates the conditions that life encounters while trying to survive.

In addition, Efficient Microbes is already a low ph. product (ph. is in the range of 3.0 – 3.5). Tests done on Efficient Microbes show the microbes survive in a wide ph. range from as low as 1.0 up to 13.0.

Q. I have been using your product for a while now but have heard that the micro-organisms are destroyed by the hydrochloric acid in the stomach before they even reach the colon.

To answer your question, specific tests done by our parent company in the USA confirm that the microbes in Efficient Microbes survive ph. levels as low as 1.0 This is lower than the ph. of the stomach. The fact is that the natural microorganisms that occur in the gut arrived there via the stomach, so while some may not survive, it is generally the ones we don’t want! The ph. of Rawbiotics is in the range of 3.0 – 3.5 (Mainly lactic acid) which is already quite low.

One of the key purposes of the stomach is to act as a sterilizing or sanitizing tank. The low ph. kills almost all of the pathogens provided we chew the food correctly. Our ancestors as recently as 100 years ago ate food that would probably kill most of us today!

In addition, the microbes in Efficient Microbes are extremely robust. Most conventional “probiotics” are produced from what is known as pure cultures and tend to be very fragile, so the chances are that a lot of them will be affected by the stomach acid. The multi-class, multi-strain nature of Efficient Microbes means it is very adaptable under a wide ranging set of environmental variables.

Q. Why are there white flakes on the top of the surface?

This is the natural yeast that forms when the product is exposed to oxygen (in other words, once the seal is broken) Do not shake it, it is normal for it to be there. 

Q. Can I take Efficient Microbes health products with other medications?

Yes, you can.  The gastro-intestinal tract’s healthy function relies on the presence of beneficial bacteria. Beneficial bacteria aid in digestion, correct pH balance (acidity), the processing of nutrients and the prevention of the build-up of harmful bacteria. Beneficial bacteria do not interfere with medication.  In fact, they are almost completely killed off with the use of antibiotics and the immune system is hugely compromised by the toxins in most medical drugs. Taking Efficient Microbes Probiotics help to protect the body from harmful toxins.

Q. Are Efficient Microbes products Vegan Friendly?

Efficient Microbes products are suitable for vegetarians and vegans. No Animal derived products are used in the culturing or production of our products.


Q. Why should one not shake the product?

Because the product is a “live” microbial product.

Q. Do I have to refrigerate the product?

No, it is a “live” microbial product. The microbes go dormant if refrigerated. Store at room temperature out of direct sunlight.

Q. Can I give Efficient Microbes probiotics to babies? What age can they start to take Efficient Microbes and what dosage?

Yes – Depends on age of baby. New born babies, a couple of drops. Increase with age to half teaspoon and then one teaspoon. Use Rawbiotics KIDS specially formulated for babies and children.

Q. Can I use the Efficient Microbes probiotics in a nebulizer?

Yes, use as a substitute in the same dosage as the recommended pharmaceutical products.

Q. How will I know if the product has gone off?

The product has a 6 week shelf life once the bottle has been opened. It will get a really “rotten” smell when it goes off.
