Intervention consists of daily administration of 2g probiotic Lactobacillus plantarum P8, administered daily at a fixed dosage of 10 log CFU/sachet/day and continue for 12 weeks.

Dietary Supplement: Lactobacillus plantarum P8

Placebo

PLACEBO COMPARATOR

Intervention consists of daily administration of 2g placebo (no probiotic bacteria), administered daily and continue for 12 weeks.

Dietary Supplement: Placebo

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Male or female subjects
  • years old
  • No severe illness
  • BMI within a healthy range
  • Score between 13 -20 (moderate stress level) on Cohen's Perceived Stress Scale (PSS)
  • Willing to commit throughout the experiment

You may not qualify if:

  • Type-1 diabetes (one of the main metabolite of Lactobacillus is acetic acid. Acetic acid has been reported to affect lipid metabolism in the liver and fat digestion in the pancreas in animal studies, and has been applied in obesity studies)
  • Long term medication due to certain severe illness (certain medications may interfere with the survivability of Lactobacillus in the gut, for example the interactions between probiotics and warfarin
  • HIV/AIDS (there has been no substantial data on the detrimental effects of probiotics on AIDS patients. However, AIDS patient may be immune-compromised in the sense of "leaky gut" that may lead to bacterial translocation, including translocation of Lactobacillus outside the gut environment, into the blood stream)
  • Glucose-6-phosphate dehydrogenase (G6PD) deficiency (there has been no substantial data on the detrimental effects of probiotics on G6PD deficiency people. However, certain strains of probiotics have been reported to benefit RBC irregularity disorders such as spur cells formation. One of the main mechanisms, involve the alteration of RBC membrane. Although this is a benefit, we are unsure of the effects on G6PD deficiency people, with weaker RBC).
