Who is Manufacturer of Synbiotic 365?

The Synbiotic 365 supplement is manufactured by United Naturals, which was founded in 2017 by a Canadian owner. This organization aims to produce health supplements, and Synbiotic 365 is their first product.

The founder began the company in an attempt to help his girlfriend, who struggles with digestive issues. Together with renowned doctor Vincent Pedre, they developed these special probiotics.

How Does Synbiotic 365 Work?

This supplement contains 3 elements: Prebiotics, Probiotics, and B Vitamins. Probiotics are strains of bacteria that are beneficial for digestive functioning and help to strengthen the immune system.

So you may be wondering, what’s the difference between Pre and Probiotics? The prebiotics act like food for the good probiotics to consume and thrive in your gut.[1]

The research by Gill Jenkins, renowned researcher's extensive study on The Role of Prebiotics and Probiotics in Human Health, with a specific focus on gut and immune health. Research suggests that prebiotics and probiotics can have positive effects on gut and immune health. Prebiotics are dietary fibers that serve as food for beneficial bacteria in the gut, while probiotics are live microorganisms that, when consumed in adequate amounts, provide health benefits.They may also impact immune-related mechanisms, such as strengthening the gut barrier function, regulating inflammation, and modulating the immune response.

This unique mix brings helpful probiotics into your system and keeps them there, while at the same time preventing the growth of harmful bacteria. It is, of course, important to remember that other fruits, vegetables, and grains can act as prebiotics for probiotics in your diet to thrive.

This product is a symbiotic, which Science Direct defines as, “a combination of prebiotics and probiotics that act synergistically promoting gastrointestinal health by improving survival and adherence of live probiotics.”

The B vitamin complex can help to close any deficiencies you may have. B vitamins are crucial to proper human health and functioning. They play essential roles in regular body functions so deficiencies can be problematic. Research suggests, that B vitamins help enzymes function efficiently in the body.[2] Note that B-vitamins are water-soluble and typically present in sufficient quantities in a healthy diet.

Synbiotic 365 Ingredients - Are They Safe & Effective?

Here is a closer look at some of the specific ingredients:

Lactobacillus Casei

This is one strain of probiotic that is known to be effective at lowering cholesterol levels, and it could also assist with alleviating allergy symptoms. It also helps to regulate your digestive system and could help reduce some types of diarrhea. Research has also shown that this probiotic can survive transit through the human digestive tract, which is an important factor when considering a probiotic.[3]

United Naturals Synbiotic 365 Supplement Facts

Synbiotic 365 Supplement Facts

Vitamin B12

This is an essential nutrient that supports tasks such as brain health, red blood cell synthesis, and DNA production in the human body. While evidence from studies states that vitamin B12 is not directly linked to colon cleansing, it is still needed to make sure you are getting enough of this mineral in your diet. Since our bodies are unable to produce vitamin B12, we must obtain it from meals like meat and seafood.[4]

Chicory Root Inulin

This prebiotic is a type of fiber derived from plant foods. Chicory root is rich in inulin, a soluble fiber found in many plants. The small intestine can’t absorb inulin. It goes to the large intestine, where it’s consumed by bacteria. According to study, Bacteria found in the colon can be helpful or harmful, so it is important to make sure we get plenty of good probiotics in our diets. This substance, in combination with a probiotic, can lessen constipation, promote digestive health, and increase good bacteria in your colon.[5]

  1. Stormie M.

    Great product, but a little pricey...!!!!
    Probiotics have proven to be extremely beneficial for me. I've been taking them in along with a diet and exercise routine for a few months now, and I've experienced good digestive health and weight loss. This is an excellent product. Everyone should at least try it. But I believe it is overpriced.

    Does It Actually Contain Listed Ingredients?
    Is there any independent testing to see if it actually contains the ingredients listed? Any review without this is pretty useless. All it is doing is commenting on the biased producer puts on the ingredients list.

    Real Blessing For My Husband and I
    I had diarrhea for several months and thought I had IBS/IBD. Finally went to my gastro doc and had tests. Turns out I had H Pylori Infection and he prescribed two heavy-duty antibiotics and prazadole (sp) for my stomach. After the course of antibiotics, symptoms subsided for 2-3 weeks and diarrhea came back. I was to go back to the lab for a breathing test, but COVID was running rampant so didn't want to go to a lab. I have taken a probiotic/prebiotic for several years and decided to try a different one. When I got the video showing Synbiotic 365, I was skeptical to try but it really sounded great, packaging, probiotic & Prebiotic so didn't think I had anything to lose. It really worked, Regular bowel movement in 2-3 weeks maybe a bit longer BUT, I'm thinking I do have IBS/IBD at any rate this stuff really did the job for me. My husband, daughter (Adult), and I are now all now taking it. It is expensive but as long as I can afford it, I'll be buying it. Hoping my sister will try it as well as she has been diagnosed with IBS, so am confidant that it will help her as well.

    Superb Product Must try!
    This probiotic is, by far, the very best one I’ve ever taken! I’ve taken many different brands over the years and recently happened upon this one. I could not believe how great it made me feel...not just energy but regular bowel movements as well. I highly highly recommend Synbiotic 365.

  5. Gregory Johnston

    Synbiotic 365 works great!
    For the first time in years I have not had bowel issues in months. This stuff works great well worth the money as long as I am feeling good I am going to keep taking it. This is the first time in years I have not had to take antibiotics for bowel infections for months now. I love to trust me if you want something that works to buy it.

    Synbiotic 365...really love it
    I have been taking synbiotic 365 for about 3 weeks. I must say I am pleasantly surprised...I started sleeping better within 2 days. Which I am happiest about! I always have a pretty high energy level so that's hard for me to measure: but definitely more alert. I don't have a weight problem and do eat very healthily but do notice that I don't crave food. Which is a nice bonus? I would definitely recommend giving it a try. I am fortunate to have bloodwork every 4 months and a quick review with my (bioidentical) DR. So I can keep track of the vitamin levels and cholesterol. Curious to see how 365 affects the numbers!
