Lab4 Probiotics product description with probiotic strains and benefits.

Proven to reach the gut alive

A common challenge when supplementing with probiotics is their ability to survive stomach acid and colonise the gut. To overcome this we use a blend of 4 acid-resistant strains, proven to reach the gut alive. Our live cultures are also microencapsulated and are provided alongside a prebiotic for further protection against the harsh environment in the gut.

Non-bloating prebiotic & gentle strains

To support colonisation, most prebiotics work by feeding bacteria in the gut which can cause gas and bloating. Instead, we add Aquamin, an algae extract which acts as a protective carrier. Its unique honeycomb structure transports more live bacteria to the intestines making it a non-bloating prebiotic. Many probiotic strains contain lipopolysaccharides (LPS) side-chains responsible for triggering an immune reaction so we use LPS-free strains for support without irritation. This prebiotic is also FOS-free and gentle on digestion.

Guaranteed until expiry

As our live bacteria are microencapsulated, this allows the product to be shelf-stable at room temperature, and therefore doesn’t require refrigeration. To ensure a high dose of live cultures are still present when taking the supplement, we provide a dose of 50 billion (CFU) to ensure at least 25 billion in each capsule at the time of expiry. A red desiccant canister provided in each bottle further preserves the probiotic stability over the shelf-life by absorbing atmospheric moisture.

Probiotics - clinically proven strains

The strains of bacteria in a probiotic supplement can determine their overall health benefits. We provide Lab4, a blend of 4 extensively researched strains of probiotics including lactobacillus and bifidobacterium. We deliberately prioritise using fewer strains at higher doses, ensuring a high number of live bacteria reach the intestine walls so they have a greater chance of colonising in the gut. Maintaining a good balance of these 4 strains of bacteria may also help to reduce the growth of harmful bacteria in the intestines.

Prebiotic Calcium - supports digestive enzymes

In addition to its prebiotic nature, Aquamin is also a source of plant-based calcium. The calcium carbonate helps to rapidly neutralise hydrochloric acid within the stomach, protecting live cultures, and then it also helps to balance gut flora in the intestines by creating a favourable pH, an ideal environment to encourage growth of beneficial bacteria. To further support digestive health, calcium also contributes to the normal function of digestive enzymes, aiding the breakdown of food and absorption of nutrients.

Vitamin A - supports the gut lining

Imbalanced gut bacteria is often associated with a compromised gut lining and symptoms such as bloating, discomfort and cramps. To provide additional support for gut barrier integrity, we have added vitamin A which contributes to the maintenance of normal mucous membranes of the gut. Vitamin A also has a role in the process of cell specialisation, a process that occurs after cell division where newly formed cells are able to function efficiently. We use beta-carotene, a safe alternative to vitamin A as retinol.
