Comparison Chart: Ritual Synbiotic vs Seed

Quick Look: Ritual Synbiotic vs Seed 

Before diving into the specifics of Seed vs Ritual, let’s quickly unpack what synbiotics are. Synbiotics blend prebiotics, probiotics, and sometimes postbiotics¹. Prebiotics² are fibers that fuel the beneficial bacteria in the gut (probiotics³), while postbiotics are the byproducts these probiotics produce as they break down prebiotics³.

When picking a synbiotic, there are some key factors to consider. The probiotic strains are critical, as their effectiveness is highly strain-specific⁴ and depends on the targeted condition. You’ll also want to check the number of probiotics per serving, typically measured in colony-forming units (CFUs) or in some cases, active fluorescent units⁵ (AFUs), which may more accurately count living, active cells.

Ritual provides 11 billion CFUs from two strains geared toward gut and immune health, while Seed offers a hefty 53.6 billion AFUs spread across 24 strains for more comprehensive, whole-body support. That said, the International Probiotics Association⁶ highlights that the dosage (whether in CFUs or AFUs) must align with what research has shown to be effective for the desired benefits.

In our comparison, we also looked at prebiotic content, inclusion of postbiotics, cost, third-party testing, and customer support. Both brands deliver high-quality options, but their key differences can help you decide which is the right fit for you.

Who Should Buy Ritual Synbiotic 

• Individuals seeking a 3-in-1 synbiotic for gut and immune system support
• Those who prefer the convenience of a single capsule
• People who don’t mind a minty taste 

Who Should Buy Seed

• Those 18 years or older seeking a 2-in-1 synbiotic that targets whole-body health
• People who prioritize a wide variety of probiotic strains for more comprehensive gut health support
• Individuals who prefer sustainable practices, like refills in eco-friendly, recyclable packaging

Formulation

When comparing the formulations of Ritual and Seed Daily Synbiotics, it’s important to understand the key differences before deciding which is worth your investment. Here’s a simple yet thorough look at their main ingredients and standout features to help you make an informed choice.

Seed Daily Synbiotic

Seed offers a two-in-one capsule design: an outer prebiotic capsule and an inner probiotic capsule containing 24 strains split into four blends. Let’s break it down.

Prebiotic

The outer capsule contains 400 milligrams of Indian pomegranate⁷ packed with antioxidants, fiber, and pectin⁸. Emerging research⁹ indicates that pomegranate may act as a prebiotic, supporting probiotics by protecting them as they journey through your gastrointestinal system.

Probiotics

The inner Seed probiotic shell houses 53.6 billion AFUs from 24 probiotic strains across four specialized blends:

• Digestive Health, Gut Immunity, and Gut Barrier Integrity Probiotic Blend: 37.0 billion AFUs with 16 strains:
  • Bifidobacterium longum SD-BB536-JP, Bifidobacterium breve SD-BR3-IT, Lactiplantibacillus plantarum SD-LP1-IT, Lacticaseibacillus rhamnosus SD-LR6-IT, Lacticaseibacillus rhamnosus HRVD113-US, Bifidobacterium infantis SD-M63-JP, Bifidobacterium lactis SD-BS5-IT, Bifidobacterium lactis HRVD524-US, Lactobacillus crispatus SD-LCR01-IT, Lacticaseibacillus casei HRVD300-US, Bifidobacterium breve HRVD521-US, Bifidobacterium longum HRVD90b-US, Bifidobacterium lactis SD150-BE, Limosilactobacillus fermentum SD-LF8-IT, Lacticaseibacillus rhamnosus SD-GG-BE, Limosilactobacillus reuteri RD830-FR
• Dermatological Health Probiotic Blend: 3.30 billion AFUs with 4 strains:
  • Ligilactobacillus salivarius SD-LS1-IT, Bifidobacterium lactis SD-CECT8145-SP, Bifidobacterium longum SD-CECT7347-SP, Lacticaseibacillus casei SD-CECT9104-SP
• Cardiovascular Health Probiotic Blend: 5.25 billion AFUs with 2 strains:
  • Lactiplantibacillus plantarum SD-LPLDL-UK, Bifidobacterium lactis SD-MB2409-IT
• Micronutrient Synthesis Probiotic Blend: 8.05 Billion AFUs with 2 strains:
  • Bifidobacterium adolescentis SD-BA5-IT, Limosilactobacillus reuteri SD-LRE2-IT

While we won’t cover every different strain, some of Seed’s probiotics have research backing their claims, like Bifidobacterium longum¹⁰ for skin and gut health and Lactobacillus plantarum¹¹ for heart support. 

But remember—reaping the health benefits of probiotics requires adequate doses of each strain. While Seed lists active fluorescent units for their blends, these are proprietary formulas, leaving us to guess how much of each specific strain is provided.

ViaCap® Capsule

Seed uses its innovative ViaCap® technology to shield the probiotics from stomach acid, digestive enzymes, and bile salts so they can reach the colon (large intestine) and thrive. While Seed funded the research¹² supporting ViaCap, it’s a reassuring sign that they take testing seriously and go the extra mile to verify product efficacy.

Ritual Synbiotic

Ritual’s synbiotic provides pre-, pro-, and postbiotics, all encapsulated in a minty, delayed-release capsule. Let’s take a closer look at what each component offers. 

Prebiotic

Ritual supplies 15 milligrams of PreforPro¹³, a patented prebiotic that boosts a variety of probiotics—like Lactobacillus and Bifidobacterium—in their powerful synbiotic blend.

Probiotics

Ritual delivers 11 billion CFUs from two clinically-backed probiotic strains: Lactobacillus rhamnosus¹⁴ (LGG®) and Bifidobacterium animalis ssp. lactis¹⁵ (BB-12®). These live microorganisms support digestive and immune health, potentially benefiting digestive issues like diarrhea, constipation, and irritable bowel syndrome¹⁶ (IBS).

Postbiotic

Tributyrin¹⁷, a postbiotic, converts into butyrate—a short-chain fatty acid known to support gut health, boost immune function, and reduce inflammation. With 300 milligrams per serving, this dose mirrors amounts used in clinical research, including a 2021 pilot study¹⁸. 

Delayed-Release Capsule

Ritual’s minty, delayed-release capsule helps the synbiotic blend make it through stomach acid unharmed, arriving at the colon where probiotics are most effective.

Company Policies

While Ritual and Seed share a few similarities in their policies, some notable differences set them apart:

• Return policies: Both brands offer a 30-day return policy, but only for first-time orders.
• Savings opportunities: Ritual gives new customers 20% off and offers discounts for bundling other supplements. Seed, however, focuses on loyal customers, providing 10% off a 3-month supply and 15% off a 6-month supply.
• Shipping locations: Ritual ships to the U.S., UK, and Canada, while Seed casts a wider net, delivering to parts of Asia, the UK, the U.S., Europe, North America, Australia/Oceania, and South America—with Africa soon to be included.
• Shipping costs: Ritual scores points with free shipping on all orders. Seed ships free within the U.S., but international orders come with a $10 flat fee.

Ritual Synbiotic vs Seed: Final Thoughts

While both Ritual and Seed Synbiotics share some overlap, there are a few key differences worth noting. Here’s a rundown to help you decide if one (or neither) is right for you:

• Formulation: Seed packs a punch with 53.6 billion AFUs from 24 probiotic strains, supporting everything from heart to skin to gut health. Ritual provides 11 billion CFUs and keeps it simple with two strains focused on gut balance and immune health—but it’s the only one offering postbiotics alongside prebiotics.
• Capsule innovation: Both brands use innovative capsules to ensure the probiotics make it past your stomach and into your colon, where they best survive and thrive. 
• Dosage: Seed requires two daily capsules, while Ritual requires just one minty capsule daily. 
• Subscription: Both operate on subscription models, but Seed sweetens the deal if you commit to 3 or 6 months at a time.
• Storage: No refrigeration is required for either.
• Transparency: Both are transparent about their ingredient sourcing and undergo third-party testing.
• Sustainability: Although Ritual aims to reduce its carbon footprint, its bottles aren’t recyclable like Seed’s glass jar and compostable monthly refill pouches.
