The oil matrix carrier discovery ensures that beneficial Natren strains will survive the low pH and corrosive functions of stomach acid. ⁷³ The oil matrix carrier protects and separates the super strains of acidophilus, bifidum and bulgaricus cells until they reach the intes-tinal tract. The cells are "micro-enrobed"; this process arrests their growth, keeps them separate and protects them from the onslaught of gastric juices. This helps ensure the maximum amount of naturally selected super strains survive the gastric juices to provide optimal benefit. This technology cannot be obtained from any other manufacturer in the world.

Natren’s micro-enrobing delivery system consists of sunflower oil and vitamin E, with all oxygen and water removed by a gentle chemical-free process, creating a totally anaerobic (oxygen-free) environment.

Natren’s oil matrix complex significantly improves the probiotic effect of Healthy Trinity because oil is not broken down by gastric juices; it is emulsified by bile, which is secreted by the bile duct located just above the intestines. It is important to note that Natren super strains show excellent bile tolerance, as evidenced by continuous in vitro studies conducted by Silliker Laboratories, southern California ⁴⁰.

In other words, potency can be improved substantially by maximizing the mass effect of a high-potency product using cells that are not stressed and are protected by an exceptional delivery system.

Natren’s superior supplements consistently lead the field of probiotics with recognized product quality, in several ways:

(1) Through painstaking and thorough selection of each naturally occurring super strain of beneficial bacteria used in a Natren probiotic formulation, with no artificial genetic manipulation.

(2) All strains are DNA fingerprinted, and the phenotypic potential is maximized by careful media selection. ¹⁵

(3) Proprietary validated production techniques maximize the health-giving potential of each bacteria strain.

(4) An efficacious delivery system acts as a protective environment. It is designed to maximize survival under the recommended shelf life conditions. The product will remain potent through the acidic stomach barrier, to flourish in the small and large intestines. ^40,73

(5) Each strain has been tested for bile tolerance by Silliker Laboratories. The laboratories’ Technical Director of Microbiology, Western Region, has stated that no further bile tolerance tests need to be run, as Natren strains have "demonstrated (bile tolerance) repeatedly on sequential lots for a period exceeding two years, both on MRS and Rogosa agar containing 0.15% oxgall." ⁴⁰

(6) Natren takes pride in its accomplishments over the last 20 years to identify the most effective probiotic species and strains. The company is able to offer an unconditional guarantee of potency for each listed strain through the printed expiration date on its product labels. Other manufacturers supply species designation without any clear potency statement and certainly do not offer a potency guarantee. ^57,58 The strain is seldom mentioned, and then with no clear potency guarantee. They mention many species, allowing the consumer to believe they are strains. Remember, each species has hundreds of strains. Multiply that by mentioning several species, and the label is totally useless.
