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.

Good product but broken capsule

I used this product once before and was happy with it. I received a new bottle today and when I opened it up I noticed there was white powder all over the inside. I found a broken capsule which explains it. Very strange as I've never come across this before.

The “ first responder “ for your gut !

This might be a brand for some serious probiotic users as it really seems to address all the issues from strains and amounts , to absorption and for keeping the gut lining healthy. It�s a product from the UK and even the label has a wealth of information as well as the ad page online. It�s about 50 cents a day to take, but you can�t minimize the fact that if your stomach isn�t absorbing your nutrients, all the money in the world won�t keep you healthy. A good probiotic and maybe even digestive enzymes are your first responders in the gut. This is an excellent choice . Personally, I rotate brands to get a well rounded group of strains too, but if you find one that makes you feel good, stick with it ????

Excellent works fast

I've tried several brands lately, some did nothing others were ok but this one really worked great for me. I've had issues since an out of the blue ER appendectomy a few months ago. Tons of antibiotics and invasive surgery has made elimination very difficult. I've never had issues prior to that episode but it hasn't been the same since and no amount of fiber has helped. I took one of these and the next day I was almost normal, day two back to solid productive elimination! This works fast and very effectively for me. Everyone is different and no one product will work for everyone but for me, this product is magic! I'll definitely buy this one again. You take just one a day, I like to take it at night, this is a 30 day supply. Recommend

Excellent digestive aid

This probiotic has been working very well for me so far! I�ve been taking it for about two weeks now, and it�s been helping regulate my digestion and keep things �regular�, if you know what I mean!This digestive blend is well thought out: it includes both a prebiotic and a probiotic blend. Aquamin Calcium (plant based) is used to assist in digestive enzyme production and works as the prebiotic; it prevents bloating and helps the probiotics in this formulation colonize the gut. Vitamin A is also added to support the integrity of the gut barrier. This formulation does not contain any fructo-oligosaccharides or artificial colors flavors or sweeteners. The product is also non-GMO and is suitable for vegetarians, vegans, and kosher and halal diets.All in all, it�s just a great digestive blend, and it�s been working really well for me. Definitely a winner. Five stars ?? for sure. Highly recommend.

Probiotics & Prebiotic Supplement With Live Cultures

As with anything that involves supplements, it is personal choice in what you use and whether they work or not. What works for some, sometimes doesn't work for others so it's all about trial and error. That said, biocultures like these are great for your system and these ones seem to work well.Easy to swallow and with no aftertaste, you get 30 vegan capsules for £13.99 with a £2 off voucher (at time of reviewing). Not the most expensive but not the cheapest either and I have to admit, I don't notice much difference between this more expensive one and our usual, cheaper brand.

Good performance in a pre- and probiotic supplement --- good value, too.

A gut-supporting live culture mix containing at least 25 billion colony-forming units (CFU).Designed as both a pre- and pro-biotic supplement and one that does not induce gut bloating. We experienced no discomfort or bloating when taking these capsules.The cultures used in this formula are shelf-stable and do not require refrigeration. A plus for a live culture.The full ingredient listing is on the product page and on the bottle, but the font size and curvature of the bottle make it difficulty to read. We suggest adding a QR code to the label for access to an easier-to-read listing.The small dark-brown bottle was double sealed with a shrink wrap around the lid and a foam seal atop the bottle.The capsules are medium sized, easy to swallow with a cool liquid and have no small, taste, or aftertaste.Reasonably priced at about $16 at the time of our review for a month's supply when taking one capsule a day as recommended.

Effective for me

I've been taking probiotics for a while now to improve my gut health and immune function and switching to this brand from a different one has made a noticeable difference.The capsules are dairy free and easy to swallow, with no after taste.I appreciate the simple packaging. At a cost (at time of writing)of 50 pence per day it's mid range, but it's still not cheap.

Easy to swallow and help the digestive system very effectively

Easy to swallow and help the digestive system very effectively. Only a few days after taking this product, I feel the difference for the bowel movement.

Strange one this one

Strange one this one, I famously struggled with monster hangovers until I tried this product. I now still get a manageable headache but my tummy is fine considering, I'm not taken out of action for several days.
I had tried cheaper ones with less millions units of probiotic and saw an improvement but only these ones do the job.

Seem fine

Seem fine, it’s hard to say they’ve helped but they’ve certainly not hindered.

Good product

Received quickly and well packaged. I purchased this product to see if it would help my ibs, I have been taking it for around 3 weeks with no side effects but has not yet helped with ibs. I will carry on taking for another month.

Smooth

Smooth. No stomach upset.

Excellent

Having used this product for a number of years found it has helped a lot with our gut health seem to have a lot less bloating and overall feel a lot better, used to order from amazon but they suddenly stopped having it so ordered direct delivery was a couple of days can thoroughly recommend

Been taking these for over a month now very easy to swallow pills

Been taking these for over a month now very easy to swallow pills.

No bloating experienced

My husband needed these after having to take antibiotics. He experienced no bloating and it’s good to know that he can restore his gut bacteria during taking and after the a/bs.

Brilliant

Been using these prebiotics for a while now and I have to say they are brilliant

Helping my stomach

Bought these as I’d been unwell and taking codeine painkillers along with a number of courses of antibiotics. And it had really affected my stomach. After taking these for only a month, my stomach issues have massively improved, less bloating and discomfort and back to my regular habits

Happy gut

Only took a few days for my system to adjust to taking these with minimal bloating.

Easy to take and good value

A great product! I’ve been taking it for 3 weeks and I’m feeling great - no bloating or side effects. Neutral taste and easy to swallow capsule.

Live Culture

We have only been using this live prebiotic culture, with billions of good bacteria, for a couple of weeks, and noticed a difference. Less bloating, and a more settled stomach.

We have been using several other Igennus products for a few months now. We have found them to be high quality, nutrient rich formula's and easy to absorb products... Highly Recommended!

sense of well being and good healthy living.

As we know, our gut is our second brain, I have referred this brand to my friends who had history of Gut problems where they felt much relief, gave a sense of being in a healthy supplements that helped to attain remedy from the existing issues. I believe this brand's excellent quality where am avid user of all supplements that offered me a great clarity and good mind set of well being and healthy living.

Amazing

gut felt incredible, pooping is very efficient and easier to wipe off my bum. My anus was causing me grief but since it’s stopped itching and leaking, can eat bean with no risks

Lab4 so good!

Bought Lab4 because it survives stomach acid and not all probiotics do! So far so good and have it on repeat so never miss a dose!!

Great probiotics

Make such a difference to stomach issues .. best I’ve found!
