NOW Foods Clinical GI Probiotic™ (50+ Formula) – 60 Veg Capsules
Aging, dietary changes, and everyday stress can quietly alter your digestive tract. As we reach age 50 and beyond, natural levels of beneficial colon-dwelling bacteria—especially Bifidobacteria—often decline. This shift frequently leads to sluggish bowel transit, irregular bowel habits, and uncomfortable gas or occasional abdominal bloating.
NOW Foods Clinical GI Probiotic™ is an evidence-based gut health supplement formulated with 20 Billion CFU across 9 clinically documented probiotic strains per 2-capsule serving. Anchored by the clinically researched flagship strain Bifidobacterium lactis HN019™, this specialized longevity formula helps restore microbial diversity, support optimal intestinal transit times, and reinforce healthy digestive and immune barriers in mature adults.
- ✓ Clinically Validated Longevity Strain: Features B. lactis HN019™ shown to accelerate gut transit and ease minor digestive discomfort.
- ✓ Guaranteed Viability: Formulated to deliver 20 Billion live organisms through the Best By date, not merely at time of bottling.
- ✓ Clean Formulation: Non-GMO, vegan, gluten-free, dairy-free, and third-party identity verified via DNA-fingerprinting.
How It Works: The Science of Colonic Transit & Immune Defense
A healthy human digestive system relies on balanced transit time—the amount of time it takes food to pass through the stomach and intestines. When peristalsis slows down, undigested material stagnates, fueling gas-producing bacteria that cause abdominal distension, fullness, and irregularity.
The primary driver of Clinical GI Probiotic is Bifidobacterium lactis HN019™. In a landmark double-blind, randomized, placebo-controlled clinical trial published in the Scandinavian Journal of Gastroenterology (Waller et al., 2011), adult subjects receiving HN019 demonstrated a statistically significant, dose-dependent decrease in whole gut transit time (WGTT) over 14 days, alongside substantial reductions in functional gastrointestinal symptoms including occasional bloating, constipation, and abdominal pain.
Beyond motility, this formula addresses cellular defense:
- ✓ Epithelial Barrier Integrity: Beneficial strains stimulate epithelial cells to express tight junction proteins (occludin, zonula occludens-1), preventing unwanted macromolecules and pathogens from crossing into systemic circulation.
- ✓ Immunosenescence Support: Clinical research published in the American Journal of Clinical Nutrition (Arunachalam et al., 2000; Gill et al., 2001) confirms that dietary consumption of B. lactis HN019 enhances circulating cellular immune activity in older adults, significantly boosting natural killer (NK) cell tumoricidal activity and polymorphonuclear (PMN) cell phagocytic function.
- ✓ Short-Chain Fatty Acid (SCFA) Synthesis: Colonizing Bifidobacteria and Lactobacilli ferment dietary prebiotics to yield acetate and lactate, lowering colon pH to inhibit opportunistic pathogens while nourishing colonic colonocytes.

Lab Purity, DNA Fingerprinting & Quality Standards
Live probiotic cultures are fragile and vulnerable to degradation during manufacturing, warehousing, and shipping. NOW Foods maintains one of the most comprehensive private in-house analytical laboratories in the natural products industry to guarantee that what is on the label is strictly what is inside each capsule.
- ✓ DNA-Fingerprinting (DuPont RiboPrinter®): Microbial strain substitution is a rampant issue in commercial probiotics. NOW verifies the exact genetic sequence and identity of every raw culture batch using automated ribotyping (DNA fingerprinting) to eliminate strain drift or contamination before encapsulation.
- ✓ Rigorous Contaminant Constraints: Raw batches undergo analytical screening via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and High-Performance Liquid Chromatography (HPLC) to confirm total absence of heavy metals (lead, arsenic, cadmium, mercury), residual chemical solvents, pesticides, and microbial pathogens (such as Salmonella, E. coli, yeast, and molds).
- ✓ Intertek GMP & Potency Guarantee: Manufactured under accredited Current Good Manufacturing Practices (cGMP), NOW adds deliberate overages to guarantee the full 20 Billion CFU potency through the end of the Best By date, eliminating the rapid mid-shelf degradation seen in non-verified brands.
Suggested Usage, Stacking & Safety Precautions
How to Take: As a dietary supplement, take 1 to 2 capsules 1 to 2 times daily. For general gastrointestinal maintenance, 1 capsule per day is standard. For targeted bowel regularity and active bloating relief, take 2 capsules daily.
Optimal Timing: Probiotic survival is highest when stomach acidity is buffered. Take capsules between meals or first thing in the morning with a full glass of water, roughly 20–30 minutes before food. If you are taking prescription antibiotic medications, take your probiotic at least 2 to 3 hours before or after the antibiotic dose to prevent the medicine from wiping out the live cultures.
Storage & Stability: This formula is shelf-stable at room temperature (under 72°F/22°C). However, to preserve maximum live cell count over long periods, refrigeration after opening is strongly recommended. Avoid storing bottles in high-humidity areas such as bathroom medicine cabinets.
Precautionary Guidance: For adult use only. Consult a physician prior to use if pregnant, nursing, taking prescription medications (especially immunosuppressant drugs), or if you have a medically diagnosed immunocompromised condition. Keep out of reach of children.

Frequently Asked Questions (FAQ)
Why is this formula called a 50+ probiotic?
After age 50, the human gut naturally experiences a sharp drop in indigenous Bifidobacterium colonies, which often correlates with slower digestion, harder stools, and lower intestinal barrier resilience. This formula specifically prioritizes Bifidobacterium lactis HN019 to replenish these declining populations and support bowel regularity in mature adults.
Does NOW Foods Clinical GI Probiotic require refrigeration?
This product is formulated to be shelf-stable at moderate room temperatures (below 72°F). However, refrigerating the bottle after opening protects the live organisms from heat and humidity, ensuring maximum colony potency right up to the printed expiration date.
