It has good tolerance to gastric juice and bile salts, and also has proteolytic activity. It can metabolize and produce angiotensin-converting enzyme inhibitory peptide to achieve anti-hypertensive effects.

Animal experiment results show that WKB99 can significantly reduce alanine aminotransferase, total cholesterol and blood sugar levels in the serum of high-fat mice, increase serum high-density lipoprotein cholesterol levels, and reduce liver alanine aminotransferase and triglyceride levels, indicating that Bifidobacterium animalis subsp. lactis WKB99 can lower blood lipids, lower blood sugar, and regulate liver function.

Animal experiments show that LC89 can alleviate diabetic symptoms by improving fasting blood sugar, lowering blood lipids and serum insulin, reducing inflammation, protecting the pancreas and liver, restoring intestinal flora disorders caused by diabetes, and improving body health.

Animal experiment results show that LR08 can reduce the levels of total cholesterol, triglycerides and low-density lipoprotein in the blood of obese mice, and increase the levels of high-density lipoprotein, serum insulin and glucagon-like peptide-1, which has the effects of delaying gastric emptying and suppressing appetite, proving that LR08 can regulate glucose and lipid metabolism in the body.

It has gastrointestinal fluid tolerance and antibacterial activity, can regulate intestinal flora and its metabolism, and exert a synergistic effect.
