Watch out for

Premium positioned brand — the comprehensive formula comes at a higher per-serving cost than individual commodity supplements
Powder format requires mixing — not as convenient as a single capsule for travel or on-the-go use
The brand's stated clinical trial outcomes (95% felt more energy, 85% better digestion, 80% improved sleep) are brand-attributed results, not a published peer-reviewed trial
Not available in retail — online subscription or single-purchase only

What IM8 Is

IM8 is a premium daily supplement brand co-founded by David Beckham that launched in the United States with a single core proposition: replace the five, eight, or twelve supplement bottles many wellness-focused people take every morning with a single daily scoop. The brand says it was developed in partnership with health experts it names from Mayo Clinic and NASA.

The flagship product, Daily Ultimate Essentials Pro, contains 90 active ingredients across 9 organ systems in a 12-gram serving. It is NSF Certified for Sport and independently tested against 280+ banned substances — a certification that matters most for athletes in tested sports but also signals a meaningful level of third-party quality assurance for any consumer.

What Is in the Formula

Daily Ultimate Essentials Pro is built around several categories of active ingredients:

Vitamins and minerals — The formula uses active forms where they matter most: methylated B12 and methylfolate (active-form B vitamins that bypass the MTHFR gene variant some people carry, which affects B vitamin metabolism), magnesium bisglycinate (a highly bioavailable and stomach-gentle form), and vitamin K2 as MK-7 (the long-acting form that stays active in the body across 24 hours). Other micronutrients include selenium, choline, and vitamin D.

Probiotics and digestive support — 10 billion CFU of probiotics plus prebiotics and digestive enzymes cover gut function. Including all three together — probiotic bacteria, prebiotic fiber to feed them, and enzymes to support digestion — is a more complete approach than a standalone probiotic.

Antioxidants and adaptogens — CoQ10 is included at a therapeutic-level dose (the brand cites it by name as a key ingredient). Saffron, an adaptogen with documented mood and energy research, is also part of the formula. MSM (methylsulfonylmethane) is included for joint and connective tissue support.

Greens and superfoods — The formula includes a greens and superfoods blend, though the specific ingredients and doses in the proprietary blend are not individually listed on the product page.

IM8 says in a brand-reported 12-week trial, 95% of participants reported more energy, 85% better digestion, and 80% improved sleep. These are brand-reported outcomes, not a peer-reviewed published clinical trial.

The Beckham Stack and the Longevity Formula

The Daily Ultimate Longevity is a separate, stackable formula focused on healthy aging. IM8 describes it as containing 10 clinically proven compounds targeting the 12 hallmarks of aging — a framework from geroscience research that identifies the biological processes underlying age-related decline.

The Beckham Stack bundles both Essentials Pro and Longevity into a single daily routine: Essentials Pro for comprehensive daily nutrition and Longevity for the aging-specific layer. Travel Box Sets (seven-count sachets) are available for both formulas, making them practical for people who want to trial the product without committing to a full jar, or who need a portable format.

Shipping, Returns, and Guarantee

IM8 offers free shipping. Quarterly plan subscribers receive a 90-day no-questions-asked refund guarantee; monthly plan subscribers get a 30-day window. Customers can cancel their plan at any time, per the brand’s policy.

New subscribers to the quarterly plan receive an welcome kit with their first order, which includes a Luxe Edition Signature Bottle (the brand’s mixer).

Is IM8 Worth It vs. Alternatives?

The most direct alternative in the all-in-one powder supplement category is AG1 (Athletic Greens), which has a longer market history, similar NSF certification, and a comparably positioned premium price point. AG1’s formula contains 75 ingredients versus IM8’s 90; AG1 does not have a celebrity co-founder but does have significant athlete partnerships. Both products operate on the same philosophical premise.

Where IM8 differentiates is the dedicated longevity formula (AG1 does not have a separate longevity-specific product), the 90-day quarterly guarantee (AG1’s cancellation policy is more complex), and the Beckham Stack as a bundled option for buyers who want both daily nutrition and longevity support from one brand.

What the NSF Certification Actually Means

NSF Certified for Sport is a certification that gets mentioned in supplement marketing frequently enough that its meaning can become blurred. What it actually involves: the product has been tested by NSF International, an independent organization, to confirm that it contains what the label claims, at the labeled amounts, with no undisclosed ingredients. The specific “for Sport” variant also screens for 280+ substances banned by major sports governing bodies — WADA, USADA, NFL, MLB, NBA, and others.

For non-athletes, the relevant part is the first: does it contain what it says, at the stated dose, with no hidden contaminants? NSF certification says yes, with an independent organization staking its reputation on that answer. Not every supplement brand pursues NSF certification because it is expensive and subjects the formula to public scrutiny. IM8 carrying it for the Essentials Pro is a meaningful quality signal.

The Travel Box Sets

Both the Daily Ultimate Essentials Pro and the Daily Ultimate Longevity are available in seven-count travel box sets — individual sachets containing one serving each. These serve two purposes. First, they are the most practical format for travel: no jar, no scoop, no measuring, no checking whether a powder jar passes airline rules. Each sachet contains exactly one serving and is consumed directly from the packet or mixed with a few ounces of water.

Second, the travel boxes are a lower-commitment entry point for buyers who want to try the formula before committing to a full subscription. Seven servings is enough for a genuine week of use — sufficient to assess how the formula mixes, how it tastes, and whether the daily routine feels workable.
