If you're asking whether IM8 is worth $190 a month, the short answer is: probably not for most people — and that's worth understanding before you hand over your credit card. Gary Brecka's greens and cellular-energy stack launched in late 2025 to considerable buzz: 100-plus claimed ingredients, NAD+ precursors, CoQ10, PQQ, and a price tag that lands at roughly twice what AG1 costs. This article breaks down exactly what's in the formula, evaluates the mitochondrial-energy claims against published human trial data, and runs the literal dollar math so you can decide whether the premium is justified or whether a sensibly assembled Amazon stack does the same job for a fraction of the cost. You'll also get a clear picture of the cancellation policy before you commit.
Quick Answer: Is IM8 Worth It?
For the vast majority of supplement buyers, no — the price premium is not supported by proportionally stronger evidence.
- Best for: Existing Gary Brecka followers who want a single-scoop all-in-one, have already optimized lifestyle basics, and treat the $190/mo as a convenience fee rather than a health investment
- Not ideal for: Anyone trying to build a cost-effective supplement foundation, anyone skeptical of influencer-launched brands with limited independent verification, anyone on a budget
- What to look at before buying: Third-party testing status (IM8 does not currently carry NSF or USP certification), serving-size breakdown by ingredient category, and whether you're already getting key nutrients elsewhere
- Decision shortcut: If the NAD+ and mitochondrial-energy angle appeals, a standalone NR or NMN supplement paired with a basic greens powder costs under $60/mo and gives you cleaner dose control
What's in the Bottle
IM8 positions itself as a "complete cellular nutrition system." The label groups ingredients into several categories, though exact per-ingredient doses for many components are disclosed only within proprietary blends.
Greens and phytonutrients: Spirulina, chlorella, wheatgrass, moringa, and a mix of cruciferous vegetable powders. Standard greens-powder fare. These are present in most competitors at comparable gram weights.
NAD+ pathway compounds: Nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) — IM8 uses NR — alongside pterostilbene as a sirtuin activator. The dose of NR is not broken out separately from the proprietary blend, which is a transparency gap.
Mitochondrial support complex: CoQ10 (form unspecified on the label — ubiquinone or ubiquinol matters significantly for absorption), PQQ (pyrroloquinoline quinone), and alpha-lipoic acid.
Adaptogens: Ashwagandha (KSM-66 extract is claimed), rhodiola rosea, and lion's mane mushroom extract.
Vitamins, minerals, probiotics, and digestive enzymes: A broad spectrum panel rounding out the formula to reach the 100-ingredient figure.
The 100+ ingredients claim is technically accurate but requires context: many of those ingredients appear inside multi-compound proprietary blends where individual doses are hidden. You're buying a label narrative as much as a precise formula.
Marketing Claims vs Reality
Gary Brecka's brand voice leans hard on three pillars: cellular energy, mitochondrial optimization, and NAD+ pathway activation. Here's what the evidence actually says.
"Cellular energy" via NAD+ precursors. NR does raise blood NAD+ levels in humans — this is reasonably well-established. A 2019 trial (Conze et al., n=140) showed dose-dependent increases in whole-blood NAD+ from NR supplementation. What that trial did not show — and what no published RCT has convincingly demonstrated — is that raising circulating NAD+ translates to meaningful subjective energy, reduced fatigue, or improved physical performance in healthy adults. The gap between a biomarker shift and a lived experience is large, and IM8's marketing blurs that gap aggressively.
CoQ10 for mitochondrial support. CoQ10 has a legitimate evidence base for specific populations: statin users who experience myopathy, people with heart failure (specific dosing), and potentially endurance athletes. A 2021 meta-analysis (Liao et al.) found modest improvements in exercise capacity. For healthy adults without statin use, the benefit signal is weak. The form matters, too: ubiquinol absorbs significantly better than ubiquinone, and IM8 doesn't specify which it uses.
PQQ for neuroprotection and mitochondrial biogenesis. PQQ research in humans is thin. Most mechanistic data comes from cell and rodent studies. Human data is limited to small pilots, and no large RCT has confirmed the "new mitochondria growth" framing that circulates in biohacking communities. If an influencer sold you PQQ as a mitochondria-building supplement, that's not evidence — it's extrapolation from pre-clinical research.
Actionable takeaway: The ingredient list is real. The clinical extrapolation layered on top of it is considerably more ambitious than the human trial data supports.
Real-User Reports
IM8 is a late-2025 launch, which means the independent review corpus is thin. This is an honest limitation: we cannot point to years of Reddit community feedback the way we can with AG1.
Early user reports from r/Supplements (January-February 2026) are mixed. One early reviewer, u/biohacker_dad, posted in January 2026: "Week three on IM8 — I do feel like my afternoon slump is less pronounced, but I also started going to bed earlier that same month, so attribution is genuinely unclear."
Another r/biohacking user noted: "Taste is better than I expected for a greens powder. But $190/mo is hard to justify when I can get NR separately and just use Amazing Grass for the greens."
A critical report on Trustpilot (February 2026) flagged the cancellation process: "I had to email three times and wait 11 days before the cancellation was confirmed. Was charged for another month in the meantime."
The relative scarcity of long-term reports is itself information. A brand this new, at this price, with this level of influencer marketing should be approached with patience.
Cost Math
| Monthly | Annual | Per serving | |
|---|---|---|---|
| IM8 (subscription) | $190 | $2,280 | $6.33 |
| AG1 (subscription) | $99 | $1,188 | $3.30 |
| Amazon equivalent stack* | ~$55 | ~$660 | ~$1.83 |
*Amazon equivalent stack: a quality greens powder (Amazing Grass or Garden of Life Perfect Food Raw, $30/mo) plus a standalone NR supplement ($20/mo) plus a CoQ10 softgel (~$10/mo for a ubiquinol form). That covers IM8's three primary selling points at roughly 29 cents on the dollar.
IM8 at $190/mo is 1.9x AG1's cost and 3.5x a thoughtfully assembled Amazon stack. The premium buys you convenience and the Gary Brecka brand. It does not buy you proportionally stronger clinical evidence. Whether that convenience is worth $1,620 extra per year relative to the Amazon stack is a question only you can answer — but you should answer it with open eyes.
Cancellation Friction
IM8 reportedly requires 14-day written notice before the next billing cycle to avoid a charge. There is no in-app self-serve cancel button in the current product UX. Cancellation is processed via email to their support team.
The Trustpilot report cited above suggests the confirmation process can extend past the 14-day window if support is slow to respond. Best practice: email with "cancellation request" in the subject line, request written confirmation, and note the date in your calendar. Cancel before day 16 of any cycle to give yourself buffer.
IM8 is a commitment, not a subscription benefit. Treat the 14-day notice requirement as a friction tax on changing your mind.
How Your Body Actually Handles This Stack
Putting 100-plus ingredients into one scoop is ambitious. Here's how four of the six body-systems axes apply to IM8's formula.
Stack bomb critique. One hundred ingredients in a single scoop creates a priority problem. When each ingredient occupies a small fraction of the total volume, many individual doses fall below the thresholds used in supporting trials. If NR is present at 150 mg inside a proprietary blend alongside 12 other compounds, that's at the low end of the 250-1,000 mg range used in Conze et al. You may be paying for an ingredient list, not a clinically meaningful dose of each item on it.
Competitive absorption. IM8 delivers calcium, magnesium, iron, and zinc in a single morning scoop. Calcium and iron compete at the intestinal DMT1 transporter, meaningfully reducing iron uptake when co-ingested. Magnesium and zinc compete at overlapping transporters. The brand's "one scoop in the morning" instruction pushes all these competitors into a single absorption window. Split-dosing would improve individual mineral bioavailability, but that's not what the product format allows.
Form bioavailability. The CoQ10 form is unspecified. Ubiquinol bioavailability is substantially higher than ubiquinone, particularly in people over 40. Methylated B vitamins (methylfolate, methylcobalamin) are listed, which is genuinely positive for the estimated 40% of the population with MTHFR variants that reduce conversion from synthetic forms. That's one of the few unambiguously positive form choices in the label.
Saturation kinetics. Several B vitamin doses appear to be in the several-hundred-percent-of-RDA range based on the label. B-complex vitamins are water-soluble and the excess is excreted. This isn't dangerous, but it is expensive urine. Fat-soluble vitamins (A, D, E, K2) appear to stay within reasonable ranges, which is the more important check.
Timing considerations. Probiotics work best on an empty stomach; fat-soluble vitamins absorb better with food; the mineral competition described above is worst when everything hits at once. A single morning scoop with breakfast is the worst-case scenario for several of these interactions simultaneously. The "one scoop" convenience is real. The absorption optimization is not.
Actionable takeaway: 100-plus ingredients in one scoop is a marketing story. The absorption chemistry tells a more complicated one. If mitochondrial support is your actual goal, a smaller, focused stack gives you dose control that an all-in-one can't.
Who It's For / Who Should Skip
Who it's for: Someone already investing heavily in their health protocol who wants a single daily checkpoint and doesn't mind the $190/mo as part of a broader wellness budget. Gary Brecka's audience specifically — if you've restructured your life around his content and want the product that fits that ecosystem, the convenience argument is coherent. Also: people who've tried basic greens powders and abandoned them due to taste or habit friction. IM8's flavor profile gets genuinely positive reviews.
Who should skip: Anyone for whom $190/mo is a meaningful budget decision. Anyone in the early stages of building a supplement practice — foundational gaps (low vitamin D, low magnesium, poor sleep) will not be solved by a 100-ingredient stack at any price. Anyone expecting the NAD+ claims to deliver noticeable energy shifts: the expectation-to-evidence gap is wide enough that disappointment is likely.
The real question isn't whether IM8 has good ingredients. It does. The real question is whether those ingredients, at those doses, inside those proprietary blends, justify a premium that is more than double AG1 and more than triple a purpose-built Amazon alternative.

Conclusion: the bottom line on IM8
IM8 is a well-marketed, genuinely ambitious product from a high-profile creator. The ingredient list is real, some of the form choices are thoughtful, and the taste appears to be legitimately good. What it is not is a $190/mo value proposition for most people.
The NAD+ and mitochondrial-energy claims rest on biomarker data that doesn't yet translate cleanly to subjective health improvements in healthy adults. The 100-plus ingredient count creates absorption conflicts and likely under-doses several key compounds. There is no NSF or USP third-party certification as of early 2026. And the cancellation process is meaningfully more friction-heavy than the sign-up process.
A purposefully assembled Amazon stack — quality greens powder, standalone NR, ubiquinol CoQ10 — covers IM8's three primary selling points for roughly $50-60/mo. That leaves $130/mo for something else, or for nothing, which is also a reasonable allocation.
