IM8 vs AG1: Two Different Paths to Daily Nutrition

AG1: A Science-Led Foundation for Everyday Wellness

AG1 was developed to help people meet their daily nutritional needs in one convenient step. Its blend of more than 70 ingredients — including vitamins, minerals, and plant-based nutrients — is designed to support energy metabolism², immune function¹, and digestion⁷.

Each component is carefully selected for its quality and bioavailability, ensuring that nutrients are efficiently absorbed and utilised. Every batch is third-party tested and certified by both the Cologne List® and Informed Sport, two trusted global standards for supplement safety.

Updated regularly in line with the latest nutrition research, AG1 prioritises long-term consistency and simplicity over short-term trends.

IM8: A Comprehensive Blend for Performance and Balance

IM8’s Daily Ultimate Essentials is NSF Certified for Sport, meaning it meets strict standards for purity and banned substances, making it a trusted choice for athletes and active individuals.

Where AG1 is designed as a single daily formula intended to support a broad range of foundational health needs, IM8 takes a narrower approach. Its emphasis appears to lean more toward short-term recovery rather than the longer-term, general support AG1 is developed for.

Ingredients and Nutrient Profile: AG1 vs IM8

The biggest difference between AG1 and IM8 lies in how each product is formulated. Both are designed to deliver a comprehensive mix of vitamins, minerals, and plant-based nutrients, but the way they build that foundation – and what they prioritise – sets them apart.

Formulation Philosophy

AG1 combines more than 70 carefully selected ingredients, including electrolytes, antioxidants, and mushrooms, that work together to support energy², immunity¹, and digestion⁷. Nutrients are included in their most absorbable form, with doses calibrated to complement one another. The result is a formula focused on quality, balance, and evidence-based nutrition, refined over the course of more than a decade.

IM8 lists 92 ingredients across greens and amino acids, but more is not always better. AG1 is intentionally formulated to include only ingredients that meaningfully support foundational health^1,2,3,4, prioritising relevance and evidence over volume. Instead of taking a broad performance leaning approach, AG1 focuses on formulation precision, avoiding unnecessary additions and delivering depth where it matters most.

Bacterial Cultures and Digestive Support

Both AG1 and IM8 include beneficial bacteria. While they share the same total bacterial count, their formulations take different approaches.

AG1 includes five well-researched strains of bacteria, delivering 10 billion CFU per serving. Each serving contains:

• Lactobacillus rhamnosus GG (3 billion CFU per serving)
• Lactobacillus acidophilus NCFM (2 billion CFU per serving)
• Bifidobacterium lactis HN019 (2 billion CFU per serving)
• Lactobacillus casei LC-11 (2 billion CFU per serving)
• Lactobacillus plantarum LP-115 (1 billion CFU per serving)

AG1’s blend of bacterial cultures has also been shown in clinical studies to increase beneficial gut bacteria by more than 10 times on average.^a-c

IM8 also contains 10 billion CFU of beneficial bacteria per serving, combining multiple bacterial cultures intended to support gut balance. IM8 Daily Ultimate Essentials includes:

• Bacillus coagulans BC99
• Bacillus subtilis DE111
• Lactobacillus casei 327

*CFU stands for colony-forming units and refers to the number of viable microorganisms capable of multiplying in the gut.

Absorption and Bioavailability

The value of a supplement isn’t just about what it contains; it’s about how well your body can absorb and use those nutrients. This process, known as bioavailability, determines how effectively vitamins and minerals are absorbed and utilised by the body to provide real benefits for both body and mind.

AG1 has been refined over more than a decade, with every nutrient form selected for its bioavailability. Clinical research has shown that several key vitamins and minerals in AG1 are effectively absorbed by the body, including:

• Thiamine (B1): Supports energy metabolism.²
• Biotin (B7): Contributes to healthy skin, hair, and nervous system function.⁵
• Riboflavin (B2): Helps protect cells from oxidative stress.³
• Niacin (B3): Supports normal psychological function.⁴
• Vitamin C: Aids immune and collagen function.^1,5
• Zinc: Contributes to immunity and DNA synthesis.^1,3
• Folate (B9): Supports energy production and cell repair.^2,3

AG1 also purposefully excludes vitamin D from the powder and provides it separately in a more bioavailable form, ensuring that this essential nutrient is delivered in a way that the body can best absorb it.

By delivering nutrients in these optimal forms, AG1 is designed to support effective absorption, so each serving provides meaningful nutritional value. The formulation reflects a core principle: what matters is not only what you eat, but what your body can actually absorb.

Unlike some supplements that use nutrient forms that can be difficult for the gut to bypass and enter the bloodstream, AG1 has been evaluated in a crossover clinical trial to assess how key nutrients are absorbed and made available for use by the body. Findings from this research showed that AG1 delivers key nutrients in forms the body can absorb and use.^a

IM8 Daily Ultimate Essentials uses a multi-phase delivery system intended to stagger nutrient release, although independent evidence supporting this method is limited.

Testing, Certifications, and Transparency: IM8 vs AG1

High-quality ingredients only make an impact if a supplement is safe, consistent, and accurately labelled. Independent testing and certification ensure that every serving delivers what it claims.

Both AG1 and IM8 implement quality control processes, but they differ significantly in the depth of clinical validation. IM8 cites a single survey-based study, while AG1 has four clinical studies that specifically examine the absorption and utilisation of ingredients in the formula.

AG1: Independently Verified Quality and Cologne List® Certified

AG1 undergoes independent third-party testing for every batch, confirming purity, ingredient accuracy, and overall safety. It also carries certifications from the Cologne List® and Informed Sport, two internationally recognised testing programmes for supplements.

These certifications confirm that AG1 has been screened for banned substances and meets strict manufacturing standards. This depth of validation reflects AG1’s focus on scientific integrity and full transparency – helping customers trust what’s in every serving.

Certification and Testing Standards

IM8 undergoes third-party testing for ingredient quality and safety, holding the NSF Certified for Sport certification, which screens for banned substances and verifies label accuracy.

AG1 also holds NSF Certified for Sport certification for products sold in the US. In other markets, including Europe, AG1 follows more locally relevant quality and testing programmes designed to align with local regulatory standards and manufacturing requirements.

Transparency and Consumer Trust

Transparency is fast becoming one of the most important measures of quality in the supplement industry. With so many products on the market, consumers want clear evidence that the ingredients listed are both present and effective – not just marketing claims.

AG1 has published multiple clinical studies examining the absorption and utilisation of its ingredients, allowing methods and findings to be independently reviewed. IM8 references clinical trials in its communications, but these studies have not yet been published, which limits the ability for external verification.

IM8 vs AG1: Price, Value, and Long-Term Use

When comparing AG1 and IM8, cost is just one piece of the puzzle. Value depends on the depth of the formulation, quality of testing, and how easily each product fits into your lifestyle.

Both are designed to streamline daily nutrition by combining multiple supplements into one, but they offer different benefits and price points.

AG1: A Streamlined Investment in Daily Health

At £79 for a 30-day supply, AG1 costs £2.63 per day for a convenient scoop that replaces a long list of individual supplements, including multivitamins and bacterial cultures. Buying those separately would come to around £3.80 per day, so AG1 delivers that daily support in a more streamlined and cost-efficient way.

AG1 is supported by published human clinical studies assessing safety, tolerability, and bioavailability. Each serving contains more than 70 ingredients, with the formulation refined over time using clinical and manufacturing data rather than standalone ingredient claims.

Because AG1 is independently tested and certified by both the Cologne List® and Informed Sport, users can be confident in its safety, purity, and consistency.

For many, the true value lies in its convenience and reliability. AG1 helps eliminate supplement overlap, reduces the need to buy multiple products, and supports long-term health through one evidence-backed habit.

In fact, when compared against the combined cost of individual supplements, taking AG1 daily can save you nearly £33 per month, which equates to over £396 every year. Learn more about these savings in our guide: Is AG1 Worth the Cost per Serving?

IM8: Pricing and Product Positioning

IM8 Daily Ultimate Essentials is priced higher at £112 per 30 servings (£3.73 per day), but this can be lower depending on the subscription level you choose. While it features a long list of 90+ ingredients, the formulation includes several nutrients – such as Vitamin D – that are typically more effective when taken separately to support absorption and bioavailability.

IM8 frequently uses the term “performance” to describe its positioning, but this is not tied to clearly defined outcomes or supported by published human data measuring improvements in strength, endurance, recovery, cognition, or energy. In practice, electrolyte supplementation is unlikely to produce measurable performance benefits for most healthy adults consuming an adequate diet, outside of specific contexts such as prolonged endurance exercise, high sweat loss, heat exposure, or clinical deficiency.

AG1 has been developed and refined for more than 15 years, whereas IM8 is a newer product with just over one year on the market. Its broad ingredient list and performance-leaning positioning show a different approach to formulation rather than the kind of long-term refinement AG1 is known for.

Considering Long-Term Value

Both AG1 and IM8 fall within the same category of foundational greens-style supplementation, and when used in conjunction with a balanced diet and healthy lifestyle, they are likely to offer some benefits for many users.

The key distinction lies in how each product has been developed and substantiated. AG1 is supported by published human clinical data, including intervention studies examining digestion, nutrient status, and microbiome-related outcomes. Its formulation has been refined iteratively over time in response to emerging evidence and post-market data, rather than remaining static.

IM8, by comparison, appears to rely primarily on early-stage research and theoretical explanations to justify its ingredient choices and positioning. While this kind of evidence can help guide product design, it does not show how a supplement performs in everyday use or what outcomes people actually experience.

AG1 also benefits from a longer real-world track record, with evidence of sustained, long-term use among consumers.

Flavour and Experience: IM8 vs AG1 Compared

Taste plays a bigger role in supplement routines than most people realise. A greens powder might be packed with nutrients, but if it’s unpleasant to drink, it’s unlikely to become a lasting habit.

Texture, mixability, and flavour all influence how easily you can stick with it day after day. In this respect, AG1 and IM8 offer two distinct experiences.

AG1: Light, Smooth, and Tropical

AG1’s formula is designed to mix smoothly with cold water, creating a clean, balanced flavour that’s easy to enjoy daily. Its mild tropical taste, with hints of pineapple and vanilla, gives it a refreshing edge without being overly sweet or grassy.

The powder dissolves easily and leaves no residue or clumps, which helps make it a natural fit for a morning routine. Most users describe AG1 as light, refreshing, and easy to drink, which helps support consistency over time.

IM8: Bold, Fruit-Forward Flavours

IM8 Daily Ultimate Essentials offers a richer and more layered flavour profile. Its blend combines earthy greens with notes of chocolate, acai, and mixed berries, resulting in a taste that’s slightly more indulgent than a traditional greens powder.

The texture is thicker, creating a smoother mouthfeel when mixed with milk or plant-based alternatives. Some users find the flavour strong on its own but enjoy it as part of a smoothie or shake.

Final Thoughts

Choosing the right greens supplement depends on your goals, preferences, and lifestyle.

If you’re looking for a science-led formula designed for comprehensive nutritional support – with independently verified quality, studied bioavailability, and an easy, sustainable daily routine – AG1 offers exceptional value and trusted nutritional depth.

Each serving combines more than 70 ingredients sourced from whole foods. Every batch is independently tested and certified by both the Cologne List® and Informed Sport, ensuring the highest possible safety and quality standards.

It’s worth remembering that neither AG1 nor IM8 Daily Ultimate Essentials is a replacement for food. It’s a convenient way to complement a balanced diet and help you maintain long-term health through one simple, consistent daily habit.
