Probiotics: Feed your stomach the bacteria it needs to run at peak performance


Theres nothing flashy or exciting about probiotics. Having good bacteria in your digestive system wont make you look younger or thinner. But quite often its the little things like better digestion and regularity that can make a big difference in your day-to-day life.

Too many bad bacteria in your digestive system often caused by diet and stress can leave you feeling sluggish, bloated and irregular. It can also leave you prone to unpleasant bouts of diarrhoea and a weakened immune system. And thats where probiotics come in.

Probiotics are good bacteria that help you maintain a healthy balance of micro-organisms (or natural flora) in the gastrointestinal (GI) tract as well as in other sites in the body. They also help your intestines break down food thoroughly and absorb vitamins, minerals and amino acids efficiently.

But just as with anything else, the quality of good bacteria varies. There are dozens of different strains, and even more supplement formulations to choose from. Even yoghurt containers boast a dose of probiotic live active cultures.

With so many to choose from, how do you know which ones work the best? Well, weve found a probiotic that has a strain of good bacteria that appears to be stronger and longer-lasting than any of the other commonly used strains which means you get the best results. And its actually cheaper than eating a pot of yoghurt a day.
GI48, manufactured by Lane Labs, is a fast-acting, resilient probiotic strain called Lactobacillus fermentum KLD. 

According to Andy Lane, President of Lane Labs, this one powerful strain outperforms other probiotics, including those with multiple strains and with higher counts of bacteria.1 Thats because GI48 has two unique properties that set it apart from the rest: It survives digestion almost completely intact, and it thrives and colonizes well in the gut. And best of all you only need to take one pill every 48 hours (hence the name GI48). 

G148: The only viable option

Any probiotic has to stay alive through your digestive system in order to be effective. (This is called viability.) It needs to make it past the digestive enzymes in your saliva, the acidic digestive secretions in your stomach, and the pancreatic enzymes in your small intestine, through the waves of bile salts from your gall bladder, and past the muscular contractions that move food through your digestive tract.2 Thats a lot to ask of any substance.

But tests conducted by the supplier of GI48 showed that after three hours in simulated stomach juices, approximately 93 per cent of the original 2 billion Lactobacillus fermentum KLD bacteria were still alive and well.3 Of the other probiotics tested, the highest viability percentage was 64 per cent, and the popular probiotic L. acidophilus scored only 53 per cent.

G148: Setting up camp

Staying alive in the intestinal tract is just half the battle. The probiotic also needs to be able to adhere to the cells in your GI tract. Since your intestinal cells can only support a certain number of bacteria, the trick is to get healthy cells to adhere to the sites and to stay there long enough to colonize (grow more healthy bacteria). This is the second strength of GI48: It survives and colonizes well in the gut.

In fact, the results of another test conducted by the supplier showed that after just one dose, GI48 was present in 100 per cent of the fecal cultures of the study subjects two days later, and it was still present in 67 per cent of the cultures six days later.4 Dr. Patricia Conway, chief scientist of Probiotics at Probiomics LTD (the company that makes the probiotic in GI48), said, To my knowledge, no other probiotic has reported these detection levels after a single dose.

Researchers attribute this to the stickiness of the GI48 bacteria. Apparently under a microscope, Lactobacillus ferentum KLD is visibly stickier than other strains.5 Unlike other probiotics that appear smooth, Conway said that the individual cells of KLD stick to each other with copious quantities of a glue-like material on the outside of the bacterial cell. Of course, we have to remember that these results were presented by the supplier of GI48, but the results suggest that if you are looking to take a probiotic, GI48 could be worth a try.6

G148: Results in just a few days

Most probiotics require you to take multiple capsules throughout the day because they just arent very viable or resilient. But you only need to take GI48 once every other day to help you balance the natural flora in your digestive system.

Its even safe for those of you who are lactose intolerant. Not only is GI48 dairy-free, but it also helps break down lactose by producing the enzyme lactase. The suggested dosage of GI48 is one capsule taken every other day on an empty stomach. However, clinical trials show that you wouldnt experience negative effects even if you were to take more than the recommended dose.
