Culturelle vs Florastor vs Align vs Fivelac - What Is The Best Probiotic Supplement

Culturelle Probiotic SupplementWhen we compare probiotic supplements we need to define our comparison for a specific targeted condition, otherwise the comparison is useless. Moreover, taking the wrong probiotic can be in rare cases harmful. No reason to be scared though, the problems will disappear once the wrong probiotic is stopped, but who wants a few days of unnecessary pain? In conclusion, we need to compare apples to apples.

On this page we compare side by side the best probiotic supplements

Our contestants are Culturelle, Align, Florastor, Fivelac, Syntol, rephresh pro-b, and a few other that are very strong competitors, but they are not as renowned, as the pack's leaders. The challengers are Renew Life, Garden of Life, PB8 and Pearls.

Align Probiotic SupplementAs we see in the comparison table above, the supplements we are comparing are different in a few ways. The most important difference though, is the strains in the formulation, and the conditions that they address. This is particularly important because the various strains have different effects in our bodies, so we have to take them according to the manufacturer's claims. Even if all of them will have a positive effect in the end, it might not be in the area we needed most, or it might take longer than desired, if we use the wrong supplement.

If we look at the list above, we can see that the most reputable probiotic supplements, Culturelle, Align, and Florastor have in their composition proprietary strains, or methods. More than that, the CFU is not impressive. Regardless of the number of active colonies, those supplements work.

All of the products are shelf stable, but the manufacturers recommend you don't store them at excessive temperatures, (above 77 degree Fahrenheit).

All probiotics have a positive effect on our intestinal health. However, in certain conditions, and with certain products, we can experience side effects, such as abdominal discomfort, gas, bloating. This can happen for a few reasons, the most common are the dosage, and the prebiotic content in some formulations. Inulin is added in supplements, to boost the efficiency of the probiotics. However, because inulin is not digestible, it can cause abdominal discomfort for some people. Lowering the dose at the beginning would solve this problem. 

To conclude our assessment, the probiotic supplements listed here target different conditions, so a comparison side by side, wouldn't be right. In many cases, if you take more than one supplement you will get the most benefits.

Hands Heart on TummyWhich one is better, VSL #3, or Align. The two probiotic supplements are the best for treating IBS and other GI issues, but the two supplements approach the treatment differently; Align uses sniper precision, with a unique dose that can treat various gastrointestinal issues, whereas VSL #3 uses brute force, using the principle if the regular dose doesn't work, double it, or triple it. 

Align vs FlorastorAlign vs. Florastor probiotic supplements side by side comparison for all IBS sufferers. Learn which one works better, and why. Maximize the efficiency of the probiotic you take, by understanding all the facts.

VSL #3 probiotic supplement packageVSL #3 is one of the best probiotic supplements. Is hard to make it on the top ten list, and with so many choices, manufacturers have to compete in a market that is more and more knowledgeable, and has comparison terms. However, VSL #3 is making that top ten easily.

probiotic for intestinal bacterial overgrowth

My Gi doctor put me on a course of xifaxan to kill the bad bacteria. He also said to pick up a probiotic to take daily for the remainder of my life. I chose Align and it works wonderfully. When I ran out, I stupidly chose a different product. None featured here. I am definitely going back to Align! The flatulence and bloating are returning without the Align.

saccharomyces boulardii

Elizabeth, Are you taking a probiotic while taking xifaxan? Antibiotics are known to kill intestinal bacteria without discrimination, so that will kill all bacteria including the good ones. Without the good bacteria in your gut, the pathogens have no competition, so they can outgrow the good microbes. Talk to your Gi doctor about taking saccharomyces boulardii probiotics during the antibiotic administration. This will keep pathogens in control. If Align works for you no reason to change. I personally take more strains/products in parallel. This diversifies my microflora and give my microbiome a chance to develop. Most probiotics cause side effects at first, flatulence and bloating included. Start with low doses, and gradually increase. I eat fermented vegetables and dairy as well.

C-diff

I've been taking Flora star for 2 yrs but continue to have reoccur ancestors of C-diff....what would be a better choice? VSL#3 was recommended by my Pharmacist....any advice or suggestions would be appreciated...other than reoccurring episodes of C-diff and large amounts of strong antibiotics I am very healthy

VSL#3 is a great choice. You

VSL#3 is a great choice. You should consider introducing more prebiotics in your diet. Search this site for prebiotics and you'll have a few articles on the subject. Be careful with prebiotics, (read fiber), as too much of it for a person who is not used to it could cause problems. We have an article on that.

C Diff

Hi I read a comment you left about taking Florastor for CDiff. My mom has been battling it for a year and just started taking Florastor. Does it work?

C Diff

It does work. Make sure she eats more soluble fiber, that helps too. Let us know of your results.
