Lactobacillus rhamnosus HN001

Pregnancy, lactation, and infant trials of this strain have watched natural killer cell activity and rates of eczema in young children.

Also known asLactobacillus rhamnosus

Primary

Helps lower infant eczema risk

Given from late pregnancy through lactation, with later follow-up of infant atopic dermatitis and eczema rates, is this strain's most cited design. The mechanism relates to immune maturation and natural killer cell activity. What is tracked is whether the baby's red itchy skin and scratching fall together.

Primary

Raises natural killer cell activity

Adult and maternal blood samples can show a rise in natural killer cytotoxic activity, a mobilization of innate mucosal immunity. When seasonal infections are frequent or in postpartum recovery, mucosal defense and seasonal skin and respiratory reactions are also more often recorded together.

Primary

Support the skin barrier

This strain's trials include eczema severity and skin-barrier lipid markers, linked to Th2 balance. Beyond immune modulation, families with toddlers in repeated eczema and a monotone gut microbiota often match gaps on this skin-barrier path; continued use beats a single dose.

Diarrhoea

Given from late pregnancy through lactation, with later follow-up of infant atopic dermatitis and eczema rates, is this strain's most cited design. The mechanism relates to immune maturation and natural killer cell activity. What is tracked is whether the baby's red itchy skin and scratching fall together. People with sudden extra bowel movements and looser stools more often notice better form and a calmer abdomen after several continuous weeks.

Nasal congestion

Given from late pregnancy through lactation, with later follow-up of infant atopic dermatitis and eczema rates, is this strain's most cited design. The mechanism relates to immune maturation and natural killer cell activity. What is tracked is whether the baby's red itchy skin and scratching fall together. People who congest and drip when seasons change and keep blowing their nose more often notice clearer airways and fewer sneezes after several continuous weeks.

Dry skin

Adult and maternal blood samples can show a rise in natural killer cytotoxic activity, a mobilization of innate mucosal immunity. When seasonal infections are frequent or in postpartum recovery, mucosal defense and seasonal skin and respiratory reactions are also more often recorded together. People whose calves or cheeks feel tight and flaky more often notice moisture and less itch after several continuous weeks.

Irritable bowel syndrome

This strain's trials include eczema severity and skin-barrier lipid markers, linked to Th2 balance. People who cycle between pain, bloating, and irregular stools more often notice a calmer abdomen and more regular bowel habits after several continuous weeks.

Antibiotic-associated diarrhoea

This strain's trials include eczema severity and skin-barrier lipid markers, linked to Th2 balance. People whose stools loosen while on antibiotics more often notice form and a calmer abdomen after several continuous weeks.

Atopic dermatitis (Eczema)

This strain's trials include eczema severity and skin-barrier lipid markers, linked to Th2 balance. People with recurring red, itchy folds at elbows and knees more often notice itch and skin integrity after several continuous weeks.

Allergic rhinitis

Given from late pregnancy through lactation, with later follow-up of infant atopic dermatitis and eczema rates, is this strain's most cited design. The mechanism relates to immune maturation and natural killer cell activity. What is tracked is whether the baby's red itchy skin and scratching fall together. People who sneeze and drip in pollen season more often notice nasal patency and eye itch after several continuous weeks.

Bacterial vaginosis

This strain's trials include eczema severity and skin-barrier lipid markers, linked to Th2 balance. People with recurring discharge odour already in gynaecology follow-up more often notice longer gaps between flares after several continuous weeks.

With foodMost can be taken with food or after a meal; acid-resistant strains may also be taken on an empty stomach—go by stomach comfort
Best timeMorning, or at the same time each day
SolubilityInsoluble, Water-dispersible

Check the strain ID, CFU count, and storage conditions; different strains are not interchangeable.

General wellnessTypical daily intake for general wellness is often 1–10 billion CFU (check the strain ID)
Specific needsFor specific needs intake may be higher; typical adult daily safety upper limit is about 100 billion CFU. Do not exceed the labeled product limit on your own long term, and check the strain ID.

How oftenGenerally use daily as directed on the product label.

Cautions

Strains are not interchangeable; immunocompromised, critically ill, pregnant, or medicated people should ask a clinician first.

Interactions

  1. Immunosuppression, central lines, or critical illness (bacteremia risk)
  2. 活動性胰臟炎須問醫生
Common side effects

· Mild bloating, gastrointestinal discomfort, or stool changes may occur.

Rare but important

· People who are seriously ill or severely immunocompromised have a rare infection risk and should ask a doctor first.

Long-term dependenceNo typical addiction evidence; do not exceed labeled amounts on your own long term.
