IM8’s Daily Ultimate Longevity is a single-serve powdered supplement built around the “healthy aging” conversation that’s everywhere right now, co-founded by David Beckham and positioned as a one-sachet alternative to buying a bunch of separate longevity ingredients/supplements.
IM8’s pitch is pretty specific: this formula is designed to support all 12 hallmarks of aging using a “5-Complex System”, and they claim the powder format allows a much higher “active ingredient capacity” than capsules.
You get individual sachets (Açaí Berry + Pomegranate), and IM8 recommends mixing one with 8–10oz of cold water and taking it in the morning with a meal.

They also explicitly recommend stacking it with IM8’s Daily Ultimate Essentials (reviewed here), for “optimal longevity benefits”, as well as daily health; IM8 calls this ‘The Beckham Stack‘.
Key ingredients and claimed benefits
The formula is organized into five complexes, with IM8 listing exact doses (which I always prefer versus “proprietary blend” mystery math):
- Cellular foundation builder (5g): L-Glycine 3,000mg + Taurine 2,000mg
- Cellular protection activator / senolytics (600mg): Trans-Resveratrol 250mg + Quercetin 250mg + Fisetin 100mg
- NMN NAD+ energy booster (310mg): NMN 300mg + PQQ 10mg
- Metabolic AMPK/SIRT1 activator (106mg): Dihydroberberine 100mg + Astaxanthin 6mg
- Cellular renewal activator / autophagy (3mg): Spermidine 3mg

IM8 ties those ingredients to a long list of “noticeable” outcomes, including: energy, sleep, focus, inflammation, skin health, cognition, and “overall vitality”.
They even map it to a 30/60/90-day timeline (foundation → protection → renewal).
Taste and mixability
IM8 describes the flavor as “bright fruity notes” with pomegranate tartness, and in practice that’s pretty close to what it tastes like: fruity, slightly tangy, and not overly sweet.

Although the powder is not 100% soluble (most of it dissolves), the mix is still very drinkable, and provides a very pleasant taste.
You can easily adjust the intensity, if you want to, by changing water volume (less water = more intense, more water = lighter).

Mixability is solid if you use cold water and a shaker. If you’re sensitive to powders clumping, do the usual: water first, then sachet, then shake hard.
Performance and benefits
Before the benefit-by-benefit breakdown: I think the cleanest way to think about this product is “inputs vs outputs”.
The inputs (ingredients + doses) are clear, the outputs (how you feel) are personal, variable, and honestly influenced by sleep quality, training load, stress, and diet.
Also, IM8 sells this as a 30/60/90-day compounding plan.
That’s a smart framing for a “slow burn” supplement, but it also means you’re paying premium pricing while you wait to see if you’re a responder.
So, here are some of the benefits that you’re likely to notice if you go the full 90 day test period, and beyond:
Increased Energy
If you notice anything early, energy is usually the first “felt” signal in my experience, it’s also the most talked about one from other people.
Mechanistically, IM8 points to NMN (300mg) and PQQ (10mg) for cellular energy and mitochondria support. Mitochondria are basically your cells’ energy plants.
They take the fuel you eat (carbs/fats, plus oxygen) and turn it into ATP, which is the usable energy your body runs on, from muscle contraction to brain function.
When mitochondria aren’t working well, you tend to notice it as low energy, slower recovery, and mental fog.
What does the actual research say regarding NMN? Human trials suggest it can raise NAD-related biomarkers, but translating that into consistent, meaningful “I feel amazing” outcomes is still a mixed bag depending on the study design and the population.
Better Sleep
This one’s interesting because IM8’s “foundation builder” includes glycine (3g), which is a dose you’ll often see discussed in sleep contexts.
A lot of IM8 customer commentary also mentions better sleep fairly quickly, but I always treat that as supportive anecdote, not proof. You’re better off having something like AGZ (reviewed here), before bedtime, if better quality sleep is your goal.
Sharper Focus
This tends to get lumped in with “energy,” but the difference (for me) is whether you feel wired versus steady.
IM8 isn’t a stimulant formula, so if you do feel a mental lift, it’s more likely the “less fog, more steady” kind, not a caffeine spike, which is really what you want to aim for. Peaks and troughs are bad when it comes to energy.
I do feel a bit of a clearer mind with stronger focus, but I feel this one will depend on your diet, and is not a guaranteed effect for all.
Reduced Inflammation
This is where longevity marketing gets slippery, because “inflammation” can mean anything from sore joints to CRP on bloodwork.
IM8 leans on the senolytic trio (resveratrol, quercetin, fisetin) and positions it as clearing senescent “zombie” cells.
That’s a hot area of research, but in humans we’re still early on strong, consistent, long-term outcome data for over-the-counter senolytic stacking like this, and it will take at least the full 90 days to determine the anti inflammation benefits.
Improved Skin Health
IM8’s own 90-day timeline explicitly calls out skin health as something you may notice later in the process.
If you’re someone who already nails hydration, protein, and micronutrients, I’d expect any “skin” change from a longevity stack to be subtle, I take Pure Synergy Pure Radiance C powder with Beet Powder (review here) every day, and I have noticed a high difference in my skin health/complexion.
So, with that in mind, I haven’t noticed a huge shift from Daily Ultimate Longevity, although I may have if I wasn’t taking those other supplements.
If your basics are shaky, you’re likely to notice more.
Enhanced Cognitive Function
The “cognitive” angle gets tied to the same cellular energy + renewal narrative, and IM8 points to the later stages of consistent use.
Spermidine is the ingredient people usually associate with this category.
Reviews of the human evidence suggest a small set of intervention trials, with some positive signals, but it’s not the sort of evidence base where I’d promise a brain upgrade. Again, try and see what you think, we all respond differently.
Overall Vitality
This is the hardest one to measure, but it’s also the one most people care about: “Do I feel better in my day-to-day life?”.
If the product works well for you, this is what that looks like: steadier energy, fewer slumps, better sleep consistency, and that general feeling that you’re coping better with training + life load.
Scientific backing
IM8 anchors its concept to the “hallmarks of aging” framework, which is a real and widely cited scientific model (and yes, it’s been updated over time as the field evolves).

Where I land on the science:
- The framework is a legitimate, and useful way to organize aging biology.
- The ingredients are plausible, and many have early human research signals (biomarkers, mechanisms).
- The big missing piece is robust, long-term clinical trials on this exact formula showing durable improvements in health outcomes (not just “supports” language).
So I’d describe it as science-inspired and dose-transparent, with the usual supplement gap between promising mechanisms and proven longevity outcomes.
How and when to take it
IM8’s guidance is straightforward:
- 1 sachet daily
- Mix with 8–10oz cold water (or another beverage)
- Morning with a meal
- They suggest pairing with IM8 Ultimate Daily Essentials, if you want the full “Beckham Stack”.
Quick safety note I’d actually take seriously with this ingredient list: if you’re on meds (especially blood sugar meds, blood pressure meds, or blood thinners), pregnant/breastfeeding, or managing a medical condition, get a clinician’s input first. Polyphenols + berberine-family compounds are where interactions can pop up.

Final verdict

If you’re choosing IM8 Daily Ultimate Longevity, you’re basically making a bet on three things:
- You value convenience + transparent dosing enough to pay premium pricing.
- You like the “multi-pathway” approach (NAD support, senolytics, amino acids, metabolic support, autophagy), even though the long-term human outcomes aren’t fully settled.
- You’re willing to run it for at least 30 days, ideally closer to that 60–90 day window, then decide if it’s doing anything meaningful for your sleep, energy, and day-to-day resilience.

Stacking with Daily Ultimate Essentials, I see the logic. IM8 Ultimate Daily Essentials is more “broad foundation” (micronutrients, gut support, daily wellness), while Longevity is the targeted “aging pathways” add-on.
If you already love Essentials and you’re genuinely motivated by the longevity angle, the stack is coherent. If you’re on the fence, I’d trial Longevity solo first so you can actually tell what’s doing what.
