AG1 Pro Review: A Close Look at the New Formula With Creatine
Written by Human & AI
AG1 Pro launched on June 16, 2026 as the most advanced version of Athletic Greens’ flagship product. After fifteen years of research and formula improvements, this new version builds on the AG1 Next Gen foundation by adding three clinically-dosed ingredients specifically chosen for muscle support, recovery, and gut health. AG1 Pro keeps the complete 83-ingredient base formula and adds 5g of Creatine Monohydrate, 1.5g of Calcium-HMB, and 100mg of Zinc Carnosine at doses backed by scientific research.
This product targets active individuals, athletes, and people over 40 who want to maintain muscle mass as they age. If you already take AG1 and buy creatine separately, AG1 Pro lets you combine both into one daily drink. The formula costs $99 per month on subscription or $119 for a one-time purchase, which is $20 more than standard AG1 Next Gen.
The value becomes clear when you look at buying these three ingredients separately. Creatine monohydrate costs $20 to $30 per month, Calcium-HMB runs $30 to $50, and Zinc Carnosine adds another $15. That puts the total between $65 and $95 per month just for these three additions, meaning the $20 upgrade price for AG1 Pro makes financial sense if you would take these supplements anyway.
Key Takeaways
- AG1 Pro adds three research-backed ingredients to the AG1 Next Gen formula at clinically effective doses for muscle support and gut health
- The product costs $20 more per month than standard AG1, but saves money compared to buying creatine, Calcium-HMB, and Zinc Carnosine separately
- AG1 Pro works best for active people, athletes, and adults over 40 who prioritize muscle preservation and want an all-in-one supplement
Is AG1 Pro Worth It?
For many people, the answer comes down to whether they would purchase creatine separately. AG1 Pro includes 5g of creatine monohydrate, 1.5g of Calcium-HMB, and 100mg of Zinc Carnosine at clinically studied doses, making it a compelling upgrade for active adults and those focused on healthy aging.
AG1 Pro may be worth the upgrade if you:
- Already take creatine daily
- Exercise regularly or train with weights
- Are over 40 and focused on muscle preservation
- Want a more comprehensive gut health formula
You may prefer AG1 Next Gen if you:
- Primarily want foundational nutrition support
- Have little interest in performance-focused ingredients
- Don’t currently supplement with creatine

Evolution From AG1 Next Gen
AG1 Pro keeps the complete 83-ingredient foundation of AG1 Next Gen. You get the same 7.2 billion CFU probiotics and NSF Sport certification that made the original formula reliable for athletes and health-focused individuals.
The three additions transform AG1 from a foundational nutritional supplement into a performance and longevity product. Each new ingredient appears at its clinically effective dose, not the token amounts you often see in supplements trying to claim benefits without real results.
Creatine Monohydrate at 5g represents the exact dose used in decades of research. Calcium-HMB at 1.5g matches clinical studies on muscle preservation. Zinc Carnosine at 100mg delivers the amount shown to support gut lining integrity in published trials.
These aren't experimental additions. They're established ingredients that required reformulation of the base powder to accommodate higher serving sizes while maintaining mixability and taste.
Intended Audience and Use Cases
AG1 Pro targets people who need more than basic nutritional coverage. If you lift weights regularly, train for sports, or maintain an active fitness routine, the creatine addition eliminates a separate supplement from your routine.
The formula becomes particularly relevant after age 40. Muscle preservation becomes harder as you age, and the combination of HMB with creatine directly addresses age-related muscle loss while supporting recovery from training.
Current AG1 users who already buy creatine separately should calculate their combined spending. You're likely paying $99 to $129 per month for both products individually.
The zinc carnosine makes AG1 Pro the most comprehensive gut health product in the AG1 lineup. If you experience occasional digestive issues or want to maintain gut barrier function during training stress, this ingredient provides targeted support beyond probiotics alone.
Comprehensive Ingredient Profile
AG1 Pro delivers 86 total ingredients: the complete 83-ingredient AG1 Next Gen base plus three research-backed additions at doses used in clinical studies.
AG1 Next Gen Base Formula Overview
AG1 Pro starts with the full AG1 Next Gen formula that includes vitamins, minerals, adaptogens, antioxidants, and digestive enzymes. This base formula contains ingredients divided into several blends designed to support different body systems.
The foundation includes essential vitamins like B-complex, vitamin C, vitamin D3, and vitamin K2. You also get minerals such as magnesium, zinc, and selenium in bioavailable forms.
The adaptogen blend features rhodiola and ashwagandha. The antioxidant component includes ingredients like spirulina and chlorella. The digestive enzyme complex helps break down proteins, fats, and carbohydrates.
This base formula has been refined over fifteen years of product development. It provides foundational nutrition in a single daily serving.
Three New Clinically Studied Additions
AG1 Pro adds three ingredients at doses that match what researchers use in clinical studies.
Creatine Monohydrate (5g) is one of the most studied supplements available. The 5g dose matches the standard amount used in research on muscle strength, power output, and recovery. Creatine supports ATP production, which provides energy for muscle contractions and cellular processes.
Calcium-HMB (1.5g) helps reduce muscle protein breakdown. This ingredient supports lean muscle mass maintenance, which becomes increasingly important as you age. The 1.5g dose aligns with research on muscle preservation.
Zinc Carnosine (100mg) supports gut barrier integrity and the protective lining of your digestive tract. This addition makes AG1 Pro more focused on gut health than the standard formula. The 100mg dose matches clinical research on gastrointestinal support.
NSF Sport Certification and Probiotic Content
AG1 Pro maintains NSF Sport certification, which means the product has been tested for banned substances. This certification matters if you compete in sports that require drug testing.
The formula contains 7.2 billion CFU of probiotics across multiple strains. These beneficial bacteria support digestive health and immune function.
The NSF certification process includes testing every production batch. Third-party verification provides confidence that the product contains what the label claims without prohibited contaminants.
Product Pricing Breakdown
AG1 Pro costs more than AG1 Next Gen because of the three additional ingredients. The monthly subscription costs $99 per month, which saves you 16% compared to one-time purchases.
| Purchase Option | Price | Monthly Cost | Savings |
| Monthly subscription | $99/month | $99 | 16% |
| 3-month subscription | $267 | $89 | 25% |
| One-time purchase | $119 + $9 shipping | $128 | None |
The three-month subscription offers the best value at $89 per month. This represents a $20 monthly increase over AG1 Next Gen, which costs $79 per month on subscription.
In-Depth Look at New Ingredients
What We Like About AG1 Pro
After reviewing the formula side-by-side with AG1 Next Gen, the biggest improvement is the inclusion of ingredients at meaningful doses rather than token amounts. The 5g creatine serving alone removes the need for a separate supplement for many users.
We also like that AG1 chose ingredients with distinct purposes. Creatine supports performance and recovery, Calcium-HMB focuses on muscle preservation, and Zinc Carnosine expands the product's gut health support beyond probiotics alone.
The main drawback is price. While the upgrade can save money compared to buying the ingredients separately, AG1 Pro is still a premium supplement and may be unnecessary for people who simply want broad nutritional coverage.
AG1 Pro adds three ingredients that address muscle performance, aging, and gut protection. Each ingredient appears at the clinical dose used in scientific studies.
Creatine Monohydrate 5g: Benefits and Science
Creatine monohydrate is one of the most studied supplements in sports nutrition. It helps your body produce ATP, which is the main energy source your muscles use during exercise.
The 5g dose in AG1 Pro matches the standard amount used in most creatine research. Studies show this dose supports muscle strength, power output, and recovery after training.
Your body stores creatine in your muscles as phosphocreatine. When you need quick energy during high-intensity activities, phosphocreatine donates a phosphate group to create ATP. This process happens in seconds.
Research also shows creatine supports energy metabolism in your brain. It may help with mental tasks that require short bursts of mental effort.
You don't need to do a loading phase with creatine in AG1 Pro. Taking 5g daily will gradually increase your muscle creatine stores over 3-4 weeks.
Calcium-HMB 1.5g: Muscle Preservation and Longevity
HMB stands for beta-hydroxy beta-methylbutyrate. Your body makes small amounts of it when you break down the amino acid leucine.
Calcium-HMB reduces muscle protein breakdown. This matters most when you're in a calorie deficit, recovering from injury, or aging naturally.
The 1.5g dose in AG1 Pro represents the lower end of the clinically studied range. Research typically uses 1.5g to 3g daily. Studies show benefits for maintaining lean muscle mass, especially in older adults.
HMB works differently than creatine. While creatine helps you produce more force, HMB helps you keep the muscle you already have. This becomes more important after age 40 when muscle loss accelerates.
Research suggests HMB may also support recovery from intense training by reducing exercise-induced muscle damage.
Zinc Carnosine 100mg: Gut Health Innovations
Zinc carnosine is a chelated compound that pairs zinc with the amino acid L-carnosine. This combination stays intact longer in your stomach and small intestine than regular zinc.
The 100mg dose provides about 23mg of elemental zinc. Research shows zinc carnosine supports the integrity of your gut lining and helps maintain the protective barrier between your intestinal contents and bloodstream.
Your gut barrier prevents unwanted particles from entering your bloodstream. Zinc carnosine has been studied for its role in supporting this barrier function.
This addition positions AG1 Pro as more focused on gut health than the standard formula. If you experience digestive stress from training, travel, or dietary factors, zinc carnosine may offer additional support.
The compound also has antioxidant properties in your digestive tract. It may help protect gut cells from oxidative stress.
Ideal Users of AG1 Pro
AG1 Pro works best for people who train regularly, adults over 40 protecting muscle mass, and current AG1 users who take creatine separately.
Athletes and Active Individuals
AG1 Pro delivers 5g of creatine monohydrate, the exact dose used in research studies on strength and performance. If you train with weights, run, cycle, or play sports, this amount supports your ATP production during high-intensity exercise.
The creatine helps your muscles generate power during short bursts of activity. The Calcium-HMB at 1.5g reduces muscle breakdown after training sessions.
You get your full daily creatine dose without mixing multiple powders. The 83-ingredient base formula covers your nutritional gaps while the creatine supports your training goals.
If you work out three or more times per week, AG1 Pro consolidates your supplement routine into one drink. You don't need to buy or measure creatine separately.
Adults Focused on Healthy Aging
After age 40, your body loses muscle mass naturally. AG1 Pro addresses this through Calcium-HMB, which research shows helps maintain lean muscle tissue.
The 1.5g dose of Calcium-HMB is the amount studied for muscle preservation in aging adults. This ingredient becomes more important as you get older because muscle mass affects your metabolism, bone health, and daily function.
Creatine also supports brain health and energy metabolism as you age. The Zinc Carnosine at 100mg strengthens your gut lining, which often becomes less resilient over time.
If you're over 40 and want to preserve muscle, strength, and metabolic health, AG1 Pro targets these specific concerns. The formula combines longevity-focused ingredients with comprehensive daily nutrition.
Users Combining AG1 and Creatine
If you currently take AG1 Next Gen and buy creatine separately, AG1 Pro eliminates the extra purchase. You save time by mixing one drink instead of two products.
Creatine monohydrate costs $20 to $30 per month when purchased alone. AG1 Pro costs $20 more than AG1 Next Gen monthly, but includes three research-backed ingredients.
You get pharmaceutical-grade creatine at the clinically effective 5g dose. No measuring, no extra shaker bottles, no separate monthly orders.
The convenience matters if you travel or have a busy morning routine. One scoop gives you everything instead of managing multiple supplement containers.
Direct Comparison With AG1 Next Gen
AG1 Pro adds three ingredients to the existing AG1 Next Gen formula and costs $20 more per month. The value comes down to whether you already take creatine or HMB supplements separately, and whether you prioritize muscle health and gut integrity support.
Ingredient Differences and Added Value
AG1 Next Gen contains 83 ingredients, 7.2 billion CFU probiotics, and holds NSF Sport certification. AG1 Pro keeps all of this and adds three more ingredients.
What AG1 Pro adds:
- Creatine Monohydrate (5g): Supports energy production in your cells, muscle strength, and recovery
- Calcium-HMB (1.5g): Helps prevent muscle breakdown and maintains lean muscle mass
- Zinc Carnosine (100mg): Protects your gut lining and supports intestinal barrier integrity
These three additions target muscle performance, muscle preservation, and advanced gut health support. If you already take creatine separately, AG1 Pro consolidates that supplement into your daily routine. The Calcium-HMB is particularly relevant if you're over 40 and focused on maintaining muscle mass as you age.
Assessing the Increased Price Point
AG1 Next Gen costs $79 per month on subscription. AG1 Pro costs $99 per month on subscription, which is a $20 increase.
At first glance, $20 extra might seem steep. But consider the cost of buying these three ingredients separately. Creatine monohydrate runs $20 to $30 per month for quality brands. Calcium-HMB costs $30 to $50 monthly. Zinc Carnosine adds another $15.
If you bought all three separately, you'd spend $65 to $95 extra each month. You'd also take four separate supplements instead of one drink.
The $20 premium makes financial sense if you want at least two of these three ingredients. You're essentially getting them bundled at a discount while keeping your routine simple.
When to Consider Upgrading
You should consider AG1 Pro if you currently take creatine as a separate supplement. The upgrade saves you money and reduces the number of products you need to buy and consume daily.
People over 40 benefit most from the Calcium-HMB addition. This ingredient specifically helps maintain muscle mass, which naturally declines with age. Combining it with creatine creates a strong muscle preservation stack.
Athletes and active individuals who train regularly get value from all three additions. The creatine supports performance and recovery. The HMB reduces muscle breakdown during intense training periods. The Zinc Carnosine helps maintain gut health, which often suffers under training stress.
Stick with AG1 Next Gen if you don't train regularly and have no interest in creatine supplementation. The base formula provides comprehensive nutrition support without the muscle-focused additions.
Cost Effectiveness and Value Analysis
AG1 Pro costs $20 more per month than AG1 Next Gen, but the price difference becomes more justified when you compare it against buying the three additional ingredients separately.
Subscription Options and Savings
AG1 Pro offers three purchasing options with different price points. The monthly subscription costs $99 per month and saves you 16% compared to single purchases. The three-month subscription drops the price to $89 per month (billed as $267 every three months), which represents a 25% savings.
One-time purchases cost $119 plus $9 shipping, bringing the total to $128. This option works if you want to try AG1 Pro before committing to a subscription.
The $10 monthly difference between the one-month and three-month subscription adds up to $120 in annual savings. That covers more than one full month of AG1 Pro over the course of a year.
Comparing Single Purchases
AG1 Next Gen costs $79 per month on subscription. AG1 Pro costs $99 per month, making the premium version $20 more expensive monthly.
For a three-month supply, AG1 Next Gen costs around $237 while AG1 Pro costs $267. The $30 difference over three months breaks down to just $10 extra per month for the advanced formula.
The price gap narrows when you factor in what you get for that extra cost: three clinically dosed ingredients that would cost significantly more if purchased separately.
Cost to Supplement Ingredients Separately
Buying the three added ingredients separately costs between $65 and $95 per month. Creatine monohydrate runs $20 to $30 monthly for a 5g daily dose. Calcium-HMB costs $30 to $50 per month at the 1.5g dose. Zinc Carnosine adds another $15 monthly.
This means you save between $45 and $75 per month by getting these ingredients through AG1 Pro instead of buying them separately. You also eliminate the hassle of mixing multiple supplements and taking several different products throughout the day.
The value proposition becomes clear when you need all three ingredients. Even at the lower end of separate supplement costs, you pay significantly more than the $20 monthly premium AG1 Pro charges over AG1 Next Gen.
Taste, Mixability and Potential Side EffectsÂ
AG1 Pro uses the same base formula as AG1 Next Gen, so users can expect a similar taste profile and mixing experience. The added ingredients do not significantly change the flavor or texture of the drink.
Most healthy adults tolerate creatine monohydrate well at a daily dose of 5g. Some users may experience mild digestive discomfort when first introducing creatine or increasing their supplement intake.
As with any dietary supplement, individuals with underlying health conditions or those taking medication should consult a healthcare professional before adding AG1 Pro to their routine.
Final Thoughts and Overall Assessment
AG1 Pro delivers on its promise to be a more advanced version of AG1 Next Gen. The addition of three clinically dosed ingredients makes sense for the target audience.
The math works in your favor. If you were already planning to add creatine to your routine, AG1 Pro saves you money compared to buying AG1 Next Gen plus supplements separately. The $20 monthly increase is less than what you would spend on quality versions of these three ingredients alone.
The formula targets real gaps. Creatine monohydrate at 5g gives you the exact dose used in research. Calcium-HMB addresses muscle preservation concerns for aging adults. Zinc Carnosine strengthens the gut health benefits that AG1 is already known for.
You get the most value on the three-month subscription at $89 per month. This pricing makes AG1 Pro competitive with buying a premium greens powder plus three separate supplements.
Who should stick with AG1 Next Gen? If you are under 40 with no interest in muscle performance or preservation, the standard version likely meets your needs. The base 83-ingredient formula remains unchanged and effective.
Who benefits most from upgrading? Active individuals over 40 get the best return. The combination of ingredients supports both performance and longevity goals in one drink.
AG1 Pro is not a revolutionary change. It is a logical evolution that adds meaningful ingredients at proper doses for people who need them.
Frequently Asked Questions
AG1 Pro adds three ingredients to the standard 83-ingredient formula, raises the monthly cost by $20, and targets people who want muscle support and advanced gut protection in their daily routine.
What's new in the Pro version compared with the standard formula, and how meaningful are the changes?
AG1 Pro keeps all 83 ingredients from AG1 Next Gen and adds three: Creatine Monohydrate (5g), Calcium-HMB (1.5g), and Zinc Carnosine (100mg). These aren't minor additions or trace amounts.
Each ingredient is dosed at levels used in published research. The creatine dose matches what thousands of studies have tested. The Calcium-HMB dose aligns with research on muscle preservation. The Zinc Carnosine amount is the same used in gut lining studies.
You're getting the same probiotic count, vitamin profile, and NSF Sport certification as the standard version. The changes focus on muscle function and gut barrier support.
How do the added ingredients support strength, recovery, and day-to-day performance without overstating benefits?
Creatine Monohydrate supports ATP production, which is how your cells make energy for muscle contractions. Research shows it helps with strength output, power during short bursts of activity, and recovery between training sessions.
Calcium-HMB reduces the rate of muscle protein breakdown. It doesn't build muscle on its own, but it helps you maintain what you have, especially during calorie restriction or aging.
These ingredients don't replace training or proper nutrition. They support the processes your body already uses for muscle function and energy production.
Is the creatine dose aligned with what most research considers effective for daily use, and does it replace standalone creatine?
Yes, 5g is the standard daily maintenance dose in creatine research. Most studies use either a loading phase followed by 5g daily, or just 5g daily from the start.
Creatine monohydrate is one of the most studied supplements available, with decades of data on safety and effectiveness. The form used in AG1 Pro is the same monohydrate form used in most research.
If you currently take creatine separately, AG1 Pro replaces that need. You don't need to add more on top unless you're following a specific loading protocol.
Who is most likely to benefit from the added muscle-support ingredients, especially after age 40?
People over 40 face gradual muscle loss as part of normal aging. Calcium-HMB specifically addresses this by reducing muscle breakdown, which becomes more relevant as you age.
Active individuals and athletes who train regularly benefit from the creatine for strength and recovery. Weekend athletes who do occasional high-intensity activity also see benefits from improved ATP availability.
If you already take AG1 Next Gen and also buy creatine separately, you're the most obvious candidate for the upgrade. You're consolidating two products into one daily drink.
How does the added gut-support ingredient differ from typical digestive add-ons, and what does it mean for gut barrier support?
Zinc Carnosine targets gut barrier integrity, not just digestion. Your gut lining acts as a barrier between your digestive tract and bloodstream. This ingredient supports the maintenance of that barrier.
Most digestive supplements focus on enzymes or probiotics for breaking down food or adding beneficial bacteria. Zinc Carnosine works on the physical structure of the gut lining itself.
AG1 Next Gen already includes 7.2 billion CFU of probiotics. AG1 Pro adds a layer of gut barrier support on top of that probiotic base.
Does the higher monthly price make sense when compared with buying the added ingredients separately?
AG1 Pro costs $99 per month on subscription, which is $20 more than AG1 Next Gen at $79. If you buy the three-month subscription, the price drops to $89 per month.
Buying the three ingredients separately costs significantly more. Creatine monohydrate alone runs $20 to $30 monthly for quality brands. Calcium-HMB costs $30 to $50 per month. Zinc Carnosine adds another $15 or so.
That's $65 to $95 in additional ingredients each month if purchased separately. The $20 upgrade cost to AG1 Pro makes sense if you were planning to take all three anyway. If you only want one or two of these ingredients, buying them separately might cost less.
