When it comes to daily health supplements, AG1 (formerly Athletic Greens) is one of the most recognized names on the market. It’s heavily advertised, endorsed by athletes and influencers, and often described as the “all-in-one” greens powder.

But AG1 isn’t the only option anymore. Tmrw builds on what AG1 does well, like its focus on probiotics and foundational nutrition, and takes it further. While AG1 centers on powdered greens and everyday coverage, Tmrw extends into longevity science, combining NAD⁺ precursors and research-backed compounds that support energy, repair, and long-term resilience.

In other words, AG1 covers the basics. Tmrw is built for the future of health.

Quick Comparison: Tmrw vs AG1

What AG1 Offers

AG1 is one of the most visible supplements on the market, thanks to widespread marketing campaigns and influencer endorsements. Its formula is designed to give you:

• Greens and phytonutrients from ingredients like spirulina, alfalfa, spinach, and chlorella.
  
  

• Vitamins and minerals to cover dietary gaps.
  
  

• Probiotics and digestive enzymes for gut health support.
  
  

This makes AG1 essentially a broad nutritional top-up. It can be helpful for someone who eats very few vegetables or struggles to get a range of nutrients from food.

However, AG1 has limitations:

• It does not include NAD⁺ precursors like NMN, which are central to energy production and cellular health.
  
  

• It lacks autophagy activators such as CaAKG, spermidine, or urolithin A, which are key to repairing damaged cells.
  
  

In short, AG1 works as a greens powder and multivitamin replacement, but it is not built around the science of longevity.

What Tmrw Offers

Tmrw approaches supplementation from a very different angle. Instead of covering general nutrition, it focuses on longevity science and the compounds most consistently studied in humans for healthy aging.

NAD⁺ and Mitochondrial Support

• 500mg NMN: one of the most researched NAD⁺ precursors, shown to restore cellular energy.
  
  

• CoQ10 (150mg, clinical dose): supports mitochondrial function and heart health.
  
  

• Pterostilbene + B-complex vitamins: synergistically support NAD⁺ metabolism.
  
  

Together, these ingredients help maintain energy at the most fundamental level: your mitochondria.

Longevity Activation Blend

To go beyond maintenance and actively support long-term health, Tmrw includes compounds shown to influence key pathways of aging, from inflammation and oxidative stress to cellular signaling.

• Glycine: foundational amino acid for methylation balance, collagen formation, and detoxification.
  
  

• Quercetin: antioxidant flavonoid that helps regulate inflammation and senescence.
  
  

This blend helps activate the body’s intrinsic longevity programs, working across multiple molecular pathways to enhance repair, resilience, and vitality.

Autophagy and Cellular Renewal

• CaAKG (950mg): supports autophagy and reduces age-related decline.
  
  

• Spermidine and Urolithin A: compounds studied for their ability to recycle damaged cells and promote repair.
  
  

These ingredients target cellular cleanup systems, supporting longevity from within.

Cognitive and Stress Support

• L-theanine and Rhodiola: adaptogens to balance stress and mood.
  
  

• Taurine (1,500mg) — linked to cardiovascular and neurological health.
  
  

This makes Tmrw not only a longevity product but also a formula that supports mental clarity and resilience.

Gut Health and Nutrient Absorption

• 10B CFU probiotics (10 strains): a diverse blend for digestive and immune health.
  
  

• Prebiotics and digestive enzymes: to enhance absorption and reduce digestive discomfort.

Vitamins and Minerals

• Activated B-complex and methylated folate: optimize energy metabolism and DNA repair.
  
  

• Essential minerals (magnesium, zinc, selenium): close common nutritional gaps and support enzyme activity.
  
  

• Vitamins D3, C, and E: foundational support for immunity, skin integrity, and antioxidant defense.
  
  

While Tmrw focuses on advanced longevity mechanisms, it also covers the nutritional essentials, ensuring total support from the basics to the most advanced cellular functions.

Key Difference in Philosophy

The biggest distinction is in what each brand is trying to achieve:

• AG1 aims to be a convenient nutritional safety net. If you don’t eat enough vegetables, it provides a concentrated greens powder plus basic vitamins and probiotics.
  
  

• Tmrw aims to change how your cells age. By including NMN, CoQ10, CaAKG, spermidine, and other longevity compounds, it focuses on energy, repair, and resilience at the cellular level.
  
  

In other words: AG1 is about dietary coverage, Tmrw is about longevity science.

Who Might Choose AG1

• People who want a greens powder and don’t currently eat many vegetables.
  
  

• Those who are primarily looking for a basic nutritional top-up in one product.
  
  

• Users who value convenience and don’t mind proprietary blends or undisclosed dosages.

Who Might Choose Tmrw

• Anyone focused on long-term healthspan, energy, and cellular repair.
  
  

• People who already eat a balanced diet and want to go beyond “nutritional insurance.”
  
  

• Those who prefer transparent formulations with clearly dosed, research-backed ingredients.
  
  

AG1 covers today. Tmrw is built for tomorrow.
