PS23 & HT-PS23


Lacticaseibacillus (Lactobacillus)

  • Isolated from the human gut


  • Vegan, KOSHER and HALAL

  • Clinically studied for safety and effectiveness

  • HT-PS23 (PS23 strain postbiotics): shelf-stable, no need for refrigeration, resistant to harsh GI conditions, can be added to any food, beverage, or supplement product

Key functions & benefits

  • Boosts mitochondria function to fight adverse effects of aging

  • Replenishes BDNF (brain-derived neurotrophic factor) for memory and cognition

  • Helps maintain muscle strength and increases protein uptake

  • Balances dopamine (motivation) and serotonin (mood)

  • Reduces cortisol (stress) levels throughout the body

  • Lowers inflammation, raises antioxidants and strengthens immune function

  • Improves GI function and healthy gut microbiota

Ongoing research

The development of our strains is guided by scientific findings. PS23's benefits for neural and muscle health, with a focus on aging conditions, are being demonstrated in clinical trials and preclinically, with many of the results already published.

How psychobiotics work

Our "microbiota-gut-brain axis" is made up of gut microbes and the two-way connection between our enteric (intestinal) and central nervous systems. Probiotics interact with other gut microbes, our food, and all of the other cells and molecules in our GI tract. Resulting health benefits include SCFAs (short-chain fatty acids), balanced neurotransmitters and hormones, and modified cellular gene expression.

Using multiple pathways from within our gut, PS23 can benefit multiple symptoms of aging, including memory and muscle decline. This may happen due to improved mitochondria health, enhanced nervous system function (including adjusted BDNF, dopamine, serotonin, and cortisol levels), or modulated ghrelin hormone (which may preserve muscle and increase protein absorption).

It was discovered that even after being killed by heat, PS23 postbiotics (HT-PS23) are still very beneficial. HT-PS23 expand the range of applications of this incredible strain.
