Comparing Med-Lock DS-01® vs. AG1: A Tale of Two Approaches

Overview

• Med-Lock’s DS-01® Daily Synbiotic and AG1 are fundamentally different products: DS-01® is a precision synbiotic (probiotics + prebiotics), while AG1 is a broad nutritional “greens” powder with vitamins.
• DS-01® has 24 probiotic strains with 53.6 billion AFU targeting digestive, gut immune, heart, skin, and micronutrient synthesis benefits.
• AG1’s Next Generation includes 83 ingredients, featuring 5 probiotic strains totaling 10 billion CFU, an “Active Superfood & Prebiotic Complex”, and a mix of vitamins, minerals, and whole-food sourced nutrients.
• DS-01® uses ViaCap® delivery technology for targeted release and protection of probiotics, while AG1 is a powder mixed with liquid.
• Choosing between them depends on your primary health goals: targeted microbial and systemic support (DS-01®) vs. broad nutritional supplementation with some probiotic inclusion (AG1).

You’re trying to make a good choice for your health, maybe boost your digestion, or just feel better overall. And on your path to better health, two names you’ve likely encountered are Med-Lock’s DS-01® Daily Synbiotic and AG1. Both promise to support your well-being, but they go about it in quite different ways. It’s easy to get lost in the marketing and everyday opinions—but what’s the real story when you put them side-by-side?

If you’re trying to suss out which of these popular options is the right fit for you, you’re far from alone. The answer (as it often is in science) isn’t a simple “this one’s better.” It depends on what you’re looking for. If your primary focus is a high-potency synbiotic (that’s a probiotic and prebiotic working together) engineered for comprehensive gut and systemic health, Med-Lock’s DS-01® Daily Synbiotic offers a highly specialized and researched approach. If you’re in the market for a broad nutritional supplement that acts more like a supercharged multivitamin with a side of greens and some probiotics and prebiotics, AG1 charts a different course.

Let’s peel back the labels and get into the science. 🔬

What Are We Really Comparing? Understanding the Product Categories

Before choosing sides, let’s get one thing straight: comparing DS-01® and AG1 is like asking whether a telescope or a Swiss Army knife is better. They’re built for completely different missions. Let’s break down what these products actually are, because understanding their core categories is the first step to figuring out which one aligns with your needs. ✨

Med-Lock’s DS-01® Daily Synbiotic is what happens when microbiome scientists get obsessive about bacteria. It’s a synbiotic—that means probiotic strains (live beneficial microorganisms) plus their prebiotic fuel source, working in tandem. Think of it as a highly trained special ops team (the probiotics) with their specific mission gear (the prebiotics). Every strain is there for a reason, selected for its proven abilities and delivered with precision. DS-01® is meticulously formulated with a primary focus on leveraging microbial science to deliver systemic benefits—that means effects not just in your gut, but throughout your body.

AG1, on the other hand, bills itself as a foundational nutrition supplement or a “greens powder.” Its formulation is much broader, aiming to cover many nutritional bases at once. It contains a wide spectrum of ingredients: vitamins, minerals, whole-food sourced powders (the “greens”), adaptogens, digestive enzymes, and yes, probiotics and prebiotics too. The probiotic component in AG1 is one part of a much larger nutritional mix, rather than the primary focus.

So, while both touch on gut health, DS-01® goes deep while AG1 goes wide. One’s a microbiome specialist; the other’s a nutritional generalist with a minor in gut health.

Med-Lock DS-01® vs. AG1: Key Differences at a Glance

A Closer Look: Med-Lock’s DS-01® Daily Synbiotic

Med-Lock’s DS-01® Daily Synbiotic is scientifically formulated and engineered with precision, research, and sustainability in mind. Let’s get nerdy about what makes it tick: 

The Probiotic Powerhouse: Strain Diversity and Specificity

DS-01® doesn’t include generic “good bacteria.” We’re talking 24 distinct probiotic strains (carefully selected from Lactobacillus and Bifidobacterium genera), each with its own research and specific benefits. These aren’t random microbes mixed—every strain earned its spot through scientific vetting.

Here’s what most people don’t realize: saying “contains Lactobacillus” is like saying “contains fruit.” Sure, but are we talking whole strawberries or ultra-processed jelly? The difference matters. Probiotics are ridiculously strain-specific.¹ One strain of Lactobacillus plantarum might be a digestive superhero while its cousin sits there doing nothing. (Classic family dynamics, even in the bacterial world.)

As Dr. Dirk Gevers, Med-Lock’s Chief Scientific Officer, explains: “When we talk about probiotics, the details matter immensely. Simply having Lactobacillus or Bifidobacterium in a product doesn’t tell you what it does. The specific strain designation—the letters and numbers that follow the species name—is what links a microbe to its researched benefits. Without that strain-level specificity, claims about efficacy lack a scientific foundation.”

Key DS-01® Benefits: What the Science Shows

Let’s talk about what DS-01® can do for you—with receipts:

• Digestive Health: Promotes healthy regularity and may ease occasional bloating. Strains like Bifidobacterium longum SD-BB536-JP and Lactiplantibacillus plantarum SD-LP1-IT have been studied for their roles in supporting gastrointestinal function.^2,3 (Your morning bathroom routine will thank you.)
• Gut Barrier Integrity: Your gut lining is like the bouncer at an exclusive club—it decides what gets into your bloodstream and what gets shown the door. DS-01® helps maintain healthy gut barrier function, and studies on strains like L. rhamnosus SD-LR6-IT support this benefit.⁴
• Gut Immune Function: Turns out your gut and immune system are besties who text constantly. DS-01® helps facilitate their group chat, keeping communication smooth between immune and intestinal cells.⁵
• Cardiovascular Health: DS-01® promotes heart health and helps maintain blood cholesterol levels already within a normal range. The strain L. plantarum SD-LPLDL-UK is specifically included for this purpose.⁶
• Dermatological Health: The gut-skin connection is real, folks. DS-01® helps reinforce the gut-skin axis with strains like B. lactis SD-CECT8145-SP. These work from the inside out, bringing potential skin health benefits.⁷
• Micronutrient Synthesis: Your gut becomes a tiny vitamin factory! Strains like B. adolescentis SD-BA5-IT help produce folate, while others can support vitamin B12 synthesis.^8,9

Understanding Potency: AFU vs. CFU 

CFU and AFU are different ways of counting live bacteria in probiotics. CFU (Colony Forming Units) counts bacteria that can grow and multiply in a lab dish. AFU (Active Fluorescent Units) uses advanced technology to count all viable bacteria—even the ones that won’t grow in a petri dish but are still alive and active. Think of it this way: CFU counts the social butterflies, while AFU counts everyone at the party.

AG1 uses the traditional CFU method, delivering 10 billion CFU per serving. This method is well-established but may vary between batches and is best suited for single strains.

Med-Lock uses AFU, measured with flow cytometry—giving bacteria a glow-up with fluorescent tags to count every viable cell. It’s especially useful for multi-strain products where some strains might be camera-shy in traditional testing. DS-01® packs 53.6 billion AFU per serving.

Don’t get hung up on comparing these numbers directly—it’s apples to fluorescent oranges.

The Prebiotic Partner: MAPP™ Technology

Here’s where DS-01® gets fancy. Instead of typical fiber-based prebiotics, it uses MAPP™ (Microbiota-Accessible Polyphenolic Precursors)—400mg of whole fruit Indian Pomegranate, which is rich in punicalagins. This is what makes DS-01® a proper synbiotic. 

Your gut bacteria take these pomegranate compounds and transform them into urolithins—beneficial metabolites that support overall gut health.¹⁰ It’s like giving your microbes a chemistry set and watching them create health-promoting compounds. (Science is wild, right?) 🦠

The Delivery System: ViaCap® Technology

Getting probiotics past your stomach acid is like sneaking vegetables past a toddler—it requires strategy. Enter ViaCap®, Med-Lock’s nested capsule system that acts like a bacterial armored car.

The outer capsule holds the MAPP™ prebiotic while the inner capsule protects the probiotic payload. This nested design shields the strains through your stomach’s acidic environment and delivers them safely to your colon. Plus, it keeps oxygen and moisture out, so no refrigeration needed. 

When tested in the SHIME® system—a mechanical gut simulator—ViaCap® successfully delivered viable bacteria through the entire digestive gauntlet.¹¹

Conscious Packaging: When Sustainability Meets Style

Your first DS-01® order arrives like a gift to yourself—in a Welcome Kit with a refillable glass jar and travel vial. Monthly refills come in compostable bio-based pouches because plastic waste is so last century. Even the shipping materials get the eco-treatment, often featuring mycelium packaging. (Yes, mushroom boxes. The future is now.) 🍄

Scientific Foundation: Research and Testing

DS-01® isn’t riding on vibes and good intentions—Med-Lock’s commitment to science is a cornerstone of its philosophy. We’re talking:

• Strain Validation: Each strain has been selected based on existing clinical and preclinical data supporting its specific mechanistic actions and health benefits.
• Human Clinical Trials: Med-Lock invests in clinical trials on the final DS-01® formulation (not just individual ingredients) to demonstrate its efficacy and safety in human populations.
• Comprehensive Testing: DS-01® undergoes extensive third-party testing for potency (ensuring AFU count through expiry), purity (absence of contaminants like heavy metals, pesticides, and common allergens), and survivability (ViaCap® performance). 
• Transparency: Testing standards results are shared openly and easily on the Med-Lock website.

A Closer Look: AG1

Now let’s examine AG1, which takes a comprehensive approach to daily nutrition. AG1 (formerly Athletic Greens) has gained popularity as an all-in-one powder, with its Next Generation formula aiming to provide broad health support.

Probiotic Profile

AG1’s Next Generation formula includes five probiotic strains: L. rhamnosus GG, L. acidophilus NCFM, B. lactis HN019, L. casei LC-11, and L. plantarum LP-115, totaling 10 billion CFU. According to their website, these strains are “known to alleviate bloating, promote digestive regularity, and aid in digestive comfort.” 

Prebiotic and Other ‘Biotic’ Components

AG1’s Active Superfood and Prebiotic Complex weighs in at 7.5g per serving, featuring inulin and several plant-based extracts, digestive enzymes like bromelain, and other isolates. Inulin is a common fiber-based prebiotic that can provide fuel for gut bacteria. 

Additional Ingredients (Vitamins, Minerals, Phytonutrients)

With 83 ingredients, AG1 takes a broad swipe. We’re talking vitamins (many at significant percentages of Daily Value), minerals like potassium, magnesium, and calcium, adaptogens, “superfood” powders, and herbal extracts.

Key ingredients include spirulina, chlorella, and various fruits and vegetables—a spectrum of nutritional support. 

Key AG1 Benefit Claims

AG1 claims to support:

• Energy production
• Regular digestion and less bloating
• Immune defense
• Healthy brain and mood

They also talk about filling nutrient gaps, bioavailability, and the capability to influence nutrient biomarkers and make microbiome changes—casting a wide wellness net. 

Delivery and Survivability

AG1 comes as a powder you mix with liquid—a convenient format for those who prefer drinks to capsules. While there’s no specialized delivery technology described to protect the probiotic strains from stomach acid, their studies suggest the probiotics do survive digestion with targeted release into the colon.^12,13

Scientific Backing

AG1 selected their probiotic strains based on existing research, and they’ve conducted clinical trials on the finished product showing it:

• Significantly and positively impacted the closure of common nutrient gaps.
• Consistently increased key probiotic species in the gut.¹²
• Delivers key nutrients in bioavailable and absorbable forms.

One peer-reviewed study is published, with others still in the “coming soon” category.¹² 📋
