8 reasons people are switching to IM8 from AG1.

Vitamin D3 + K2 in the same scoop. One ritual, not two.

Vitamin D sits at the crossroads of immunity, bone health and mood — and most adults are short. IM8 builds it into the daily ritual: 1,200 IU (50 mcg) vegan D3 paired with 100 mcg vitamin K2 (MK-7), in the same scoop. K2 directs calcium into bones and away from arteries — the pairing clinicians recommend.

AG1's main powder contains no vitamin D. Instead, AG1 sells a separate D3 oil. The logic is that dietary fat helps absorption — true, though not strictly required. From a daily-adherence lens the trade-off is simple: putting D in the primary scoop favors consistency; separating it adds another product to remember.

A complete 4-tier gut system — including a postbiotic AG1 doesn't have.

Gut health is a cornerstone of wellness. As IM8 advisory-board member Prof. Suzanne Devkota (Director of Cedars-Sinai's Microbiome Research Institute) puts it, diet–microbiome interactions shape inflammation, metabolism and everyday wellbeing. AG1 Next Gen offers a sensible base: prebiotics, probiotics and bromelain as a single enzyme.

IM8 builds a 4-tier system that reflects the latest microbiome science — and adds the layer ISAPP's 2024 consensus calls out as the evidence-based next step: postbiotics. IM8's probiotics are spore-forming strains (Bacillus subtilis DE111® + Bacillus coagulans BC99®), clinically shown to survive stomach acid and reach the intestine alive — which is also why IM8 is shelf-stable while AG1 recommends refrigerating the pouch after opening.

Joints, hydration and recovery — all in the same scoop.

AG1 Next Gen is best understood as a daily base layer: broad-spectrum vitamins/minerals, a recognizable greens blend, and core gut support. What you won't find are the supports many active users add on top: joint & connective-tissue support, a real electrolyte system, an amino-recovery complex, a clinical dose of CoQ10.

IM8 folds all of those into one scoop — at disclosed, clinical levels. That's the difference between "a baseline you add to" and "a complete scoop you don't."

Cellular renewal science AG1 simply doesn't have.

Supporting daily health is essential. The most forward-thinking strategies also target the fundamental processes of aging at the cellular level. IM8's proprietary CRT8™ Complex is a synergistic blend designed to support autophagy — the body's natural "cellular cleanup" system that recycles old and damaged cell parts.

CRT8™ combines Spermidine, Trans-Resveratrol and other research-grounded compounds. In the new Pro formula, the dose is +300% higher than the original (25 mg → 100 mg). This proactive cellular layer is not present in AG1 in any form.

Independently tested. Certificates of Analysis published on the website.

For any daily supplement, third-party testing is non-negotiable. Heavy metals like lead, cadmium and arsenic are cumulative toxins — even trace amounts taken daily build up in tissues. IM8 commissions independent testing for the full spectrum of contaminants and publishes the Certificate of Analysis and NSF Certified for Sport reports directly on the website.

For context: a ConsumerLab investigation identified 2.1 mcg of lead and 5.66 mcg of phthalates per serving in AG1's original formula. A 2025 Consumer Reports analysis of 23 popular greens/protein shakes found two-thirds contained concerning levels of lead — with several shelf leaders running 1,200%–1,600% above safe daily limits.

Real evidence on the finished formula. Here's what people actually felt.

IM8 commissioned the San Francisco Research Institute to run an independent, placebo-controlled, randomized clinical trial on Daily Ultimate Essentials over 12 weeks (NCT06655597). These are the participant-reported outcomes — not lab markers, not label claims. AG1 has no comparable peer-reviewable trial on its finished product.
