Probiotics

Probiotics

Also known as: Lactobacillus, Bifidobacterium, Beneficial Bacteria

Probiotics are live beneficial microorganisms that support gut health, immune function, and the gut-brain axis. Different strains have different benefits — strain specificity matters greatly.

Best Timing

Take on an empty stomach (20–30 min before meals) or as directed by the specific product. Some spore-based forms can be taken with food.

Absorption

Survival through stomach acid varies by strain. Enteric-coated and spore-based forms survive best. Refrigerate unless labeled shelf-stable.

  • -Multi-strain capsules – broad-spectrum support
  • -Single-strain (targeted) – for specific conditions
  • -Spore-based (Bacillus) – shelf-stable, survives stomach acid

Prebiotics (fiber)Synergy

Prebiotics feed probiotics. Combined use (synbiotics) enhances colonization.

Vitamin D3Synergy

Vitamin D supports a healthy gut barrier and microbiome composition.

ZincSynergy

Zinc supports gut lining integrity and immune function alongside probiotics.

Omega-3Synergy

Omega-3 reduces gut inflammation, creating a better environment for beneficial bacteria.

Probiotics for the prevention of antibiotic-associated diarrhea

Hempel S, Newberry SJ, et al. - JAMA (2012)

Probiotics reduced the risk of antibiotic-associated diarrhea by 42% compared to placebo.
