IM8 arrived with the loudest possible endorsement — David Beckham as co-founder — and, unusually for a celebrity supplement, a real credential behind it: NSF Certified for Sport, the certification serious athletes actually check. In a category where most “greens” brands wave vaguely at “third-party testing,” that’s a genuine differentiator, and we’ll give it full weight.
But a certification proves what’s clean, not what’s dosed. So this review holds IM8 to both standards — and the panel splits in two: a handful of quantified, clinical-strength actives, and a set of proprietary blends where the ingredients that sell the product hide their amounts. Here’s the full scorecard.
At a glance
Quick verdict
IM8 is the strongest “yes, but” in our coverage. Yes: it carries the certification we consider the gold standard, it puts clinical doses on the actives it does quantify, and a ~30 g scoop means this isn’t a pixie-dust product across the board. But: everything that makes it an “all-in-one superfood” — the 26-ingredient greens blend, the amino complex, the adaptogens, the enzymes — lives inside proprietary totals, and when you divide those totals, several marquee ingredients land below the doses their own research used.
58/100 — Mixed — is the highest score we’ve given a proprietary-blend product, and the certification is why. It’s also capped there, because a shopper still can’t verify the dose of most of what the marketing sells, and the “95% felt more energy” trial is the self-reported kind that tracks placebo.

May suit you if
- You’re a competitive or drug-tested athlete — NSF Certified for Sport is exactly the credential you need, and few rivals have it
- You want one comprehensive scoop and value clean certification over per-ingredient dose disclosure
- The quantified actives (CoQ10, MSM, saffron) are ones you’d take anyway
Skip it if
- You want to verify the dose of the superfoods, aminos or adaptogens — they’re proprietary and unstated
- You’re buying it for a specific ingredient (say, an adaptogen) that likely sits below its clinical dose
- ~$78–$183 a month is a stretch for a formula you can only partly verify

The formula: two products in one scoop
Read the panel and you’re looking at two philosophies fighting over one label. The quantified half is the good IM8: CoQ10 at 100 mg, MSM at 1,500 mg, saffron at 30 mg — these are real doses that real studies used, and they’re printed. If the whole label read this way, IM8 would be scoring in the 70s.
The proprietary half is where the score is capped. The Superfoods Blend — the thing that makes this “greens” — is one 4,100 mg number covering roughly 26 ingredients; even split evenly that’s ~158 mg each, and blends are rarely split evenly, so the tail runs low. The Amino Complex’s ~1,580 mg across eight amino acids averages ~198 mg — and clinical L-citrulline studies typically start around 3,000 mg for that one amino alone. Adaptogens and enzymes average ~18–20 mg per ingredient, which is garnish for compounds like ashwagandha (studied at 300–600 mg). Formula 15/25 for the genuine quality present; dosage & transparency 9/20, because the ingredients that define the product won’t show their amounts.
Testing — the part IM8 wins outright
This is where IM8 earns its price and separates from the greens pack. NSF Certified for Sport is not a marketing badge a brand awards itself — it’s an independent program that tests each production batch against 290+ banned substances, verifies label accuracy, and audits the manufacturing. For any competitive or drug-tested athlete, it’s the difference between “trust us” and “checkable on NSF’s public database.” Almost nothing else in the all-in-one category carries it. We score testing 17/20 — the highest mark in this review by a wide margin, and the single strongest reason IM8 exists on the recommendable side of the shelf. (Confirm the current batch’s listing on NSF’s database, as with any certified product.)
What it’s like to take
We have not yet purchased this product; this section reports themes, not our hands-on findings. Reported feedback is generally favorable on taste and mixability — a ~30 g comprehensive scoop that people find palatable — with the common reservations being price and auto-renewal friction. Experience: 6/10 pending our own trial.
The math
At ~$78 a month for Essentials Pro, IM8 runs about $2.61 a serving — roughly $936 a year, and the Longevity and Beckham Stack tiers climb to $104 and $183 a month. That is premium-of-premium pricing for the category. Part of it buys something real — the NSF certification and the quantified actives — and part of it buys proprietary blends you can’t price-check ingredient by ingredient. Value: 7/15, lifted above the proprietary-blend norm specifically by the certification.

What to buy instead
If NSF Certified for Sport is why you’re here, IM8 is a legitimate pick — few all-in-ones match it, and for a drug-tested athlete that can be decisive. If it’s disclosed produce nutrition you want, our fruit & vegetable comparison scores brands that print their amounts, and our Grüns review (50/100) covers the gummy end of the greens category with the same proprietary-blend caveat.
Final assessment
IM8 is the most legitimate premium all-in-one we’ve scored, and it earns that with the one thing money genuinely should buy in this category: independent, batch-level certification that what’s in the tub is clean and banned-substance-free. Where it quantifies, it doses like it means it. What keeps it at 58 — a Mixed, not a recommendation — is that the ingredients selling the “superfood” story hide behind proprietary totals that, divided out, put several marquee compounds below their clinical doses, at a price near the top of the market, propped up by a testimonial-grade efficacy trial. For a drug-tested athlete, the certification can justify the buy outright. For everyone else, you’re paying premium money to verify only part of the label. The upgrade path is one decision away: publish the per-ingredient amounts, and this score climbs. Talk with your provider before adding a comprehensive formula like this, especially if you take medications.
Frequently asked questions
Is it NSF Certified for Sport?
Yes — batch-tested for 290+ banned substances, the category’s strongest credential and IM8’s best reason to buy. Verify the current batch on NSF’s public database.
Does it hide doses?
The marquee blends do: Superfoods ~4,100 mg/~26 ingredients, Amino ~1,580 mg/8 (below clinical citrulline alone), adaptogens/enzymes ~18–20 mg each. Quantified actives (CoQ10 100, MSM 1,500, saffron 30) are clinical.
How much?
Checked July 17, 2026: ~$78/month Essentials Pro ($2.61/serving); Longevity ~$104; Beckham Stack ~$183.
Does the trial prove it works?
The cited 12-week RCT reports self-rated outcomes (95% “more energy”), which track placebo for wellness products. The certification is the real evidence; the efficacy trial isn’t.
