The average probiotic pill does not work, according to the popular new digestive health supplement Seed. Backed by big name investors like Peter Thiel (an early investor in Facebook and PayPal), the unlikely teamup of Jessica Biel and Cameron Diaz, and the former chair of the World Health Organization panel that first defined “probiotics,” Seed is taking the cutting edge, much talked about world of gut health and aims to offer the best, most complete, most digestible, most healthful probiotic/prebiotic supplement on the market. (Or supplements, as there’s a male and female version.)
It’s hard to have the Best Possible gut health supplement given it’s such a new area of research that’s constantly evolving, but Seed is indeed an innovative supplement that goes to extraordinary lengths to make sure you actually benefit from the ingredients.
A digestive health supplement that may be more effective than its competitors at delivering healthy bacteria and fiber to the right spots in your digestive tract.
Seed Synbiotic Ingredients
As a “synbiotic,” Seed combines both probiotic bacteria — 58.1 billion of them — and prebiotic fiber, with the fiber potentially helping to nourish and extend the longevity of the bacteria. (More on that below.)
The ingredients can be split up into different probiotic blends and the prebiotic fiber. With probiotics, a diverse array of bacteria is as important or possibly more important than the number of bacteria, so Seed has included dozens of different forms. Here’s how they fall into the categories.
Digestive Health and Gastrointestinal Immunity (46 billion AFU)
Bifidobacterium longum SD-BB536-JP, Lactobacillus acidophilus SD-LA2-IT, Lactobacillus plantarum SD-LP1-IT, Lactobacillus rhamnosus SD-LR6-IT, Bifidobacterium breve SD-BR3-IT, Bifidobacterium infantis SD-M63-JP, Streptococcus thermophilus SD-FP4-IT, Bifidobacterium lactis SD-BS5-IT, Lactobacillus reuteri SD-LRE2-IT, Bifidobacterium lactis SD-150-BE, Lactobacillus rhamnosus SD-GG-BE, Lactobacillus reuteri SD-RD830-FR.

Seed Synbiotic Benefits
The truth is that you need to very well versed in microbiology and biochemistry to actually know just how useful this product is, but Seed does a valiant job of communicating the “basics” to the layperson.
As a primer: you’ve got trillions of bacteria living in your digestive tract helping you to break down food and absorb its nutrients. They comprise what’s called the “gut microbiome,” and we’ve known for a while that they’re crucial for digestion and might help with bloating, constipation, gas, and other symptoms of indigestion. More recently, evidence has suggested that a healthy, populous, diverse microbiome may also improve immunity, reduce inflammation, help insulin sensitivity, and boost athletic recovery.(1)(2)(3)(4)(5)(6). You know how stress can cause indigestion? Some research is suggesting that the relationship between the gut and the mind is a two-way street (called the “gut-brain axis”) and a healthy gut might help to lower, or lower the risk of experiencing, stress and anxiety.(7)(8)(9)
Once again, this is an emerging area of research and these links just aren’t as ironclad as other areas of our health, like “magnesium helps you sleep.” But Seed does cite their research claiming that each of these blends may improve their namesake.(10)(11)
Prebiotic fiber helps to nourish the probiotic bacteria, and there’s evidence that a healthy intake of the stuff — found in foods like garlic, onions, and bananas, among other places — helps keep your gut microbiome happy. But some research has also suggested that taking prebiotics with probiotics helps to keep the probiotics alive and make sure they they get to your large intestine and colon, where they might be needed, before they die.(12)(13)
This brings us to Seed’s biggest claim: that it’s more effective than other probiotics.
There are a lot of areas that differentiate Seed from its rivals. As we mentioned, the combination of prebiotics and probiotics means that it might be more useful. The supplements also undergo “whole-genome testing” to confirm which strains are present in what amounts. They make sure the probiotics are cultured to ensure viability with precise pH, temperature, and other controls. They measure the probiotics in AFUs (Active Florescent Units) instead of the standard CFUs (which they claim is more precise)… are your eyes glazing over yet?
As we mentioned, it’s hard for the average person to really understand this stuff. But something that really stands out, and is a little easier for the layperson to understand, is the acid resistant coating. While a lot of studies have seen benefits to giving people probiotics, there are plenty that have found little to no benefit of consuming these critters.(14) The culprit, according to Seed and some other researchers, is the fact that bacteria may die in your stomach acid before making it to the guts and the colon where they’re needed.
To remedy that issue, the pills are encased in an acid resistant vegan coating, plus the prebiotic fiber is in another capsule within the first so that it’s more likely to make it through toward the end of your system before delivering the fiber where it may be the most useful.
Seed Synbiotics Price
You’re meant to sign up for a subscription: $50 per bottle per month.
That’s pricier than a lot of competitors — it’s not hard to find probiotic pills for $10 or $20 per month — but given the enormous variety and number of probiotics, the addition of the prebiotics, the innovative coating and the quality controls, I think it’s a pretty reasonable price.
Seed Synbiotics Pros & Cons
- Shelf stable for 18 months
- More strains and bacteria than you normally see
- Acid resistant coating
- Combines prebiotic fiber and probiotics
- Vegan – actually notable because a lot of probiotics come from dairy
- Gluten free, non GMO, allergen free
- Proprietary formula
- Benefits aren’t ironclad just yet
You can’t really escape the fact that this area of research is not only enormously complicated but very new, and a lot of these benefits, while backed up with some studies, don’t have decades of research supporting them. Supplement makers and journalists are prone to exaggerating the benefits of a healthy gut.
But it’s exciting. And a lot of money is being poured into research. And Seed has taken the information we have, used very stringent quality controls, and put together what may be the best digestive health pill on the market. We won’t say it’s essential to your health but if you’re thinking about buying a probiotic pill, we can’t think of a more impressive entry in the market.
