What Is Synbiotic 365?
United Naturals advertises Synbiotic 365 as an advanced formula consisting of beneficial probiotic strains and prebiotic ingredients, that when combined, can deliver lasting relief from bloat and other embarrassing digestive issues.
Based on the available clinical evidence, can you realistically expect to experience benefits like these? Furthermore, is there supporting data that taking a combination product like Synbiotic 365 will deliver better results than a standalone probiotic supplement?
In this brief article, we’ll discuss the formula’s ingredients, pricing, and competition, all aimed at helping you make an informed decision. Before diving in, though, let’s clarify what we’re talking about.
What is a Synbiotic Supplement?
Probiotics are specific bacteria strains that, when taken regularly as a dietary supplement, have been clinically shown to provide a wide variety of digestion-related benefits, in addition to boosting immune function.
Prebiotics, on the other hand, are certain ingredients that these bacteria use as an energy source upon arriving in your digestive tract.
With these details in mind, ScienceDirect explains, whether referencing Synbiotic 365 or another formula, “Synbiotics are a combination of prebiotics and probiotics that are believed to have a synergistic effect by inhibiting the growth of pathogenic bacteria and enhancing the growth of beneficial organisms.”
In other words: Synergy + Probiotics = Synbiotics.
Writing for Health.com, Anthea Levi tells us “the idea behind synbiotics is that adding prebiotics to a probiotic supplement can help ensure that the digestion-friendly microorganisms arrive in the gut alive and well. These supplements are said to be particularly useful for people with conditions like IBS, other bowel disorders, and diabetes.”
Cynthia Sass, RD, Health contributing nutrition editor, adds that when combined with probiotics, prebiotics can “also increase nutrient absorption and support bowel regularity.”
Exactly which probiotics and prebiotics does Synbiotic 365 contain?
Taking a Closer Look at Synbiotic 365’s Ingredients
According to the supplement facts label listed on the United Naturals website, Synbiotic 365 contains:
- Vitamin B1 2.4 mg
- Vitamin B2 2.6 mg
- Vitamin B3 32 mg
- Vitamin B6 3.4 mg
- Vitamin B9 800 mcg (480 mcg folic acid)
- Vitamin B12 4.8 mcg
- Vitamin B7 60 mcg
- Vitamin B5 10 mg
- Probiotic Blend 30 billion CFU – Lactobacillus acidophilus La-14, Bifidobacterium lactis Bl-04, Lactobacillus paracasei Lpc-37, Lactobacillus plantarum LP-115, Streptococcus thermophilus ST-21, Lactobacillus casei LC-11, Lactobacillus reuteri, Lactobacillus salivarius LS-33, Lactobacillus rhamnosus LR-32, Bifidobacterium bifidum BB-06, Bifidobacterium longum BL-05, Saccharomyces boulardii
- Chicory Root Inulin 300 mg
Sites like WebMD, the Natural Medicines Database, and Examine.com report that the first eight vitamins in this formula are essential for maintaining human health. For example, B1 (thiamine) is essential in the breakdown of carbohydrates, B2 also helps digest carbs, as well as proteins and fats, while Healthline tells us that every part of your body needs B3 (niacin) to function correctly.
However, they also report that unless someone’s deficient in these vitamins, supplementing them likely won’t deliver meaningful health benefits.
Probiotic bacteria are identified by their genus (e.g., Lactobacillus), which is like an extended family; their species (e.g., acidophilus), and their strain (La-14).
Lactobacillus acidophilus (whether contained in Synbiotic 365 or another supplement) was the first probiotic strain widely used, which seems to work especially well for irritable bowel syndrome (IBS) symptoms and urinary tract infections in children.
Among others, paracasei may relieve allergic symptoms and decrease skin sensitivity, plantarum produces its own antibiotics, casei may improve allergy symptoms and reduce cholesterol (along with reuteri), and rhamnosus has even been shown to help obese women lose weight.
In the Bifidobacteria genus, lactis may reduce inflammation and aid in the management of diabetes, bifidum shows promise for addressing constipation and lung infections, and longum may also be effective for constipation and airway infections, in addition to IBS and ulcerative colitis.
Finally, Streptococcus thermophilus could decrease the chances of kidney stones and increase anti-tumor activity, while Saccharomyces boulardii seems to be especially useful for addressing different causes of diarrhea.
Potential Synbiotic 365 Side Effects
As genera (the plural of genus), WebMD, Examine.com, and the Natural Medicines Database report that Lactobacillus and Bifidobacteria are likely safe for adults and children when taken as directed. Common side effects, if any, for the genera include mild, temporary intestinal gas or bloating, as well as stomach or intestinal upset.
Outside of this, WebMD indicates Saccharomyces boulardii could rarely “cause fungal infections that can spread through the bloodstream to the entire body (fungemia).” No dosages or other specifics listed.
Whether you’re considering Synbiotic 365 or another probiotic-containing supplement, have an in-depth conversation with a healthcare provider before ordering. In addition to making recommendations that could maximize value, they can also help minimize any potential side effects based on your diagnosis.

Synbiotic 365 vs. Competing Probiotic & Prebiotic Supplements
We didn’t encounter anything with the same (or very similar) formulation as Synbiotic 365 during our research.
However, we did come across dozens of competing synbiotic supplements like Syntol AMD ($40, 90 capsules), Dr. Axe Formula SBO Probiotic ($41, 60 capsules), HLC Synbiotic Intensive ($43, 7 sachets), NutriCology SymBiotics with FOS ($23, 40 servings), and Renew Life Women's Daily Probiotics plus Prebiotics ($28, 60 capsules).
From a high-level perspective, these supplements are alike in that they’re priced competitively with one another, and that each combines a relatively similar blend of probiotics, prebiotics, and other vitamins and minerals.
These often include many of the same species among the Lactobacillus and Bifidobacteria genera, vitamins like C and many within the B family, and even secondary ingredients like chicory root and different fruit extracts as energy sources.
Zooming in, the differences between Synbiotic and competing supplements mostly relate to the quantities of each ingredient they contain, as well as the form in which they’re available (e.g., capsules vs. loose powder).
Is either of these criteria important when choosing a synbiotic supplement? Perhaps not. Here’s why:
First, while probiotics and prebiotics are certainly beneficial on their own, Cynthia Sass, RD, Health contributing nutrition editor, emphasizes: “Right now we don’t have a lot of data to show that synbiotics are more effective than, say, taking probiotics [supplements] and eating a diet rich in prebiotics.”
Next, even if they are eventually shown equally as useful, Cynthia emphasizes that "Your overall pattern of eating still has the greatest impact on your health protection or risk,” so “don’t think that taking [one of these supplements] means you don’t have to pay attention to your diet.”
Together, from a value perspective, she recommends that “until more comprehensive research is conducted on synbiotics, consider sticking to swallowing a probiotic supplement or eating probiotic-rich foods in addition to prebiotic foods.”
Should You Place an Order for Synbiotic 365?
At $45 per box, Synbiotic 365 seems priced at the upper end of the spectrum compared to some other popular synbiotic supplements but has a middle-of-the-road price compared to probiotic supplements in general—some of which can near the $100 mark.
And as we outline in our Probiotic Supplement Buyer’s Guide, paying more for one of these supplements doesn’t typically translate into improved results, as reported by customers.
Other pointers we mention in the article include making sure the manufacturer provides a complete list of all the bacteria strains, as well as their dosage (as measured in colony-forming units, or CFU), both of which United Naturals lists for Synbiotic 365.
However, the company also adds a handful of vitamins that, according to sites like Examine.com and WebMD, might not provide much value for the money unless you’re deficient. Furthermore, we didn’t encounter any online customer feedback for Synbiotic 365 at the time of our research, and the company wasn’t listed with the Better Business Bureau.
Still, they advertise that all purchases come with a 30-day refund policy if the supplement doesn’t meet your needs, less S&H charges. Just make sure that you talk with your doctor first about overall value based on your diagnosis before ordering, as well as potential side effects or medication interactions.

Very positive so far
I only received Synbiotic 365 five days ago and I immediately took my first one that morning. So four days later I feel an increase in energy. But most important I don't feel bloated at all and am making regular bowel movements, although it's only five days. I will update my review.
Bottom Line: Yes, I would recommend this to a friend

I have been taking SYN 365 for three months now and see a huge difference in how I feel. I have always been very healthy but want to continue to improve. I have found that I am no longer hungry all the time despite eating less now than I did before taking SYN 365. I find myself satisfied with less and better food choices and having more energy. I walk 3 miles a day or more and sleep soundly. No stomach issues with taking the supplement.
Bottom Line: Yes, I would recommend this to a friend

I’m on opiates for back pain and have a very difficult time with my bowel movements, sometimes not going for days! I took a chance and ordered this product. After just a few days I started having bowel movements. They became more and more frequent, and now I’m beginning to go two or three times a day. I also noticed my stomach wasn’t bloated or sick as I would every day feel sick. I also noticed that I get up in the morning wide awake and cannot take any more small naps during the day. This is too hard to believe, but it’s true! All I can say is WOW! And I am very grateful for this product. It definitely is not s rip-off! I’m totally on board with this and suggest you do too.
Bottom Line: Yes, I would recommend this to a friendView all 1 commentsHide comments

Hi Laurie, first, thank you for taking the time to share your review with those of us who are interested in taking Synbiotic 365. As I read your review, I couldn’t believe that someone else suffers from the “exact” same issues as I do every day and has already tried Synbiotic before and it worked. I’m really hoping I experience the same relief and no longer need to take those afternoon naps. Plus, being able to go to the restroom regularly would be great! I hope they’re stilling working for you. I just wanted to say thank you for your review, it gave me the courage to try this product too! Take care.
