In the colon, LOSWIFT™Lactulose is degraded into short - chain fatty acids (SCFA) during bacterial fermentation. Thus, the intestinal content acidifies, the osmotic pressure rises and stool volume increases, which are the cause of the pH decreasing. This decrease in pH increases the formation of ammonium ions, which unlike ammonia, cannot diffuse through the intestinal mucosa. This leads to characterise the laxative effect of the LOSWIFT™Lactulose by a shorter colon transit time and bowel movement accelerated. All these factors are favourable for a healthy bowel. However, as for other commonly used osmotic laxatives,LOSWIFT™Lactulose can cause electrolytic imbalances in sensitive individuals. However, the action of LOSWIFT™Lactulose is more safe because it is due to its laxative action and to a proper action on the motility and colonic transit. It stimulates peristalsis by increasing acidification, gas formation and increased sense of urgency through the volume of intestinal contents.

Colon cancer develops from the lining of the large intestine or colon. In 70% of cases, the tumour grows in the sigmoid (loop located in the left iliac fossa). In the context of colon carcinoma, the lowered faecal concentrations of secondary bile salts are noticed when the LOSWIFT™Lactulose was administrated to healthy volunteers. In contrast to this given observation of LOSWIFT™Lactulose on the secondary bile salts, such observations were not systematically confirmed. It was reported that the recurrence rate of colon adenomas in the large bowel was reduced after LOSWIFT™Lactulose administration. Moreover, LOSWIFT™Lactulose suppressed DNA damage in the colon mucosa of rats treated with 1, 2 - dimethylhydrazine. These findings suggest that LOSWIFT™Lactulose may have potential protective effects against colon carcinogenesis.

LOSWIFT™Lactulose can significantly augment the absorption of calcium, if the alimentation contains at least 0.3% of calcium. Magnesium is poorly absorbed: intestinal absorption is about 30%. By performing tests on the rats, it has been shown that LOSWIFT™Lactulose promote the absorption and retention in the body of several minerals such as Ca, Mg, Zn, Cu, Fe. The effect of LOSWIFT™Lactulose on the rat's bone strength was studied. The results showed that LOSWIFT™Lactulose increases the absorption of calcium in both osteoporosis and bone strength. It has been reported that LOSWIFT™Lactulose increases the absorptions of Ca and Mg in dogs and rats, and increases the rupture strength of the femur in an ovariectomized rat model of osteoporosis. The study had evaluated the effect of LOSWIFT™Lactulose on the calcium (Ca) and magnesium (Mg) absorption. This study was performed on adult men. It showed that the absorption of calcium and magnesium increases with increasing amounts of LOSWIFT™Lactulose administration. The twenty - four volunteer adults are fed with food containing LOSWIFT™Lactulose, calcium and magnesium. A quantity of 300 mg containing 20 mg of Ca containing 44Ca and a quantity of 150 mg of Mg containing 28 mg of 25Mg was orally administered. Together with calcium and magnesium, a dose of 0 (placebo), 2 and 4 g of LOSWIFT™Lactulose is also administrated. To measure the ratios of stable isotopes, the urine samples were picked up after ingestion of the administrated calcium, magnesium and LOSWIFT™Lactulose. The results show that the urinary stable isotopes ratios increased with increasing of LOSWIFT™Lactulose quantities. Significant differences were observed in the calcium ratio between 0 and 4 g of LOSWIFT™Lactulose; and in the magnesium ratios between 0 and 2 g of LOSWIFT™Lactulose and between 0 and 4 g of LOSWIFT™Lactulose. However, the authors did not observe any change in the rate of bone resorption after LOSWIFT™Lactulose ingestion. In summary, this clinical trial has confirmed that LOSWIFT™Lactulose enhances the absorptions of Ca and Mg.

LOSWIFT™Lactulose reduces bacterial production of ammonia in the intestines, draws ammonia from the blood to the colon and then drains it through the waste. LOSWIFT™Lactulose is hydrolysed by colonic bacteria and acts as promoting agent for their growth and increasing biomass formation. However, for the synthesis of bacterial protein, ammonia and nitrogen are used, but the production of ammonia is inhibited by acidifying the intestinal content. Independent of pH, LOSWIFT™Lactulose acts by increasing the incorporation of ammonia in the bacterial proteins. In addition, it has been shown in vitro that the LOSWIFT™Lactulose inhibits the synthesis and the activity of bacterial enzymes that generate ammonia.
