For years, I’ve criticized companies that use cherry-picked science, proprietary blends, influencer references, and vague promises to “alternatively replace 20+ supplements” or “support your health.” And when it comes to green and red powders, I’d put almost all of them in the “pass” category.
When my followers asked me to review IM8, I thought it would be the same old supplement garbage. IM8 was co-founded by David Beckham and supported by many athletes and people who may be famous but I’ve never heard of… none of which impress me at all. Let’s be honest, celebrity products and endorsements are an absolutely horrible way to judge a product’s effectiveness. Why should I care if Jay Shetty or an MMA fighter thinks Beckham’s supplements are great?
What is IM8?
IM8 consists of two supplements: IM8 Daily Ultimate Essentials Pro ($346 CAD/90 days) and IM8 Daily Ultimate Longevity ($459/90 days). If you have more money to spare, the David Beckham Stack includes both products plus a convenient shaker cup and hand mixer, all for the low price of CAD$806/90 days. No matter what product you purchase, you’ll get 90 days of free access to IM8’s Transformation Program. We believe this is aimed at the same people who can afford these products: those who are least in need of a health transformation.
Once you get past the IM8’s pretty packaging and “premium” claims, the truth becomes clear.
One good thing about IM8 is that the product is NSF certified for sports. This means:
The product contains what is listed on the label. Testing for contaminants is underway. Tested for over 280 banned substances.
This is valuable information for athletes and non-athletes alike, especially when the supplement industry isn’t always honest about what some products actually contain.
That being said, NSF certification doesn’t tell you whether a supplement is actually effective. It is not intended to verify company claims or base claims on existing research. It’s strictly about quality control.
Throughout the IM8 website, you’ll see the usual claims:
Clinically proven.
95% more energy.
Improves digestion.
better sleep.
These claims are so overused and under-proven in the supplement field that it honestly doesn’t surprise me anymore. That’s not surprising since, like many other products, they were not supported in the IM8 study.
Yes, IM8 actually has research behind its product, but you don’t have to look too deep to see the flaws.
IM8 conducted a 12-week randomized, placebo-controlled trial of both Essentials Pro and Ultimate Longevity. The Essentials trial had only about 60 participants, and the Longevity trial had only 25 participants. Both studies were completed in 2025, and neither was published in a peer-reviewed journal. The IM8 site lists the results of the Essentials trial. You can see it in the screenshot below.
75% “Feel more focused”? “Feel more energy”? What does the word “feel” mean? That’s right. Because the results are clearly based on participant surveys rather than objective physiological measurements (promised but never delivered, probably because they were not up to standard). This is an important detail. Because if you’re going to make a big claim, you need big research to back it up.
Unfortunately, there is one short, small study that is mostly qualitative and has not even been published. By the way, the results of longevity research are MIA.
You don’t have to worry about all the research parameters. I want to see actual research. The link in the “Expected Results” section leads to the Clinicaltrials.gov page, but there are no further links.
FYI, the IM8 advisory board includes the doctor who blocked me for making false and misleading nutrition claims. These include Amy Shah and James DiNicorantino. It’s embarrassing to be associated with these people in any way, much less for them to sit on an “advisory board” and endorse my product. no thanks.
More is not necessarily better.
IM8 proudly touts over 90 ingredients. This is not as impressive as it sounds. Because when it comes to nutrition, especially supplements, more is not always better. Unfortunately, consumers have been conditioned to think that more ingredients equal more health and value.
There are several scientific issues with “kitchen sink” supplements, the first being their proprietary blends. And IM8 includes some of those features in both products.
I am always a vocal opponent of proprietary blends in dietary supplements. Because I think it’s a shady way to hide the actual amount of each ingredient you’re taking. Are you exceeding the safety limits? Are you below the effective dose? Is it enough to cause side effects? No one will know that a supplement is ineffective or will end up causing harm until someone discovers it.
Transparency is therefore important and we do not know if IM8 “Cellular Rejuvenation Technology 8™” contains a meaningful dose or if it contains pixie dust.
Products with multiple ingredients also have the potential problem of interactions between ingredients. When you combine dozens of vitamins, plants, probiotics, antioxidants, adaptogens, enzymes, amino acids, and phytonutrients at once, it becomes very difficult to predict how they will interact.
Ingredients may complement each other, but they may also compete for absorption. Often when you take so many ingredients together, you can’t tell what’s actually doing something.
Most people don’t need all or any of these.
This is probably my biggest criticism of multi-ingredient supplements like IM8. Supplements should fill nutritional gaps, not try to replace an entire diet or imply through marketing that they are necessary for good health.
No one needs this much vitamin C, but most of it is just excreted in the urine. Or 8000% of the DRI for vitamin B12, or this high dose of any other B vitamin readily available in food. Most of us do not need supplemental digestive enzymes, probiotics, or essential amino acids. This is all smoke and mirrors to make customers think they’re getting everything they’re not eating in their meals. It’s unreal.
In general, consuming nutrients you don’t need won’t provide any additional benefits, and consuming all of them “just in case” is not nutritionally based on scientific evidence. Most of the ingredients in IM8 are relatively harmless (aka useless) unless you are actually lacking or deficient in those nutrients. According to IM8, its ingredients are in “clinical doses,” but again, that doesn’t mean anything if the ingredients are missing or missing. Healthy people who eat a varied diet usually do not need to take this much in supplements.
I generally recommend taking targeted supplements rather than combining dozens of ingredients into one product, especially when such complex formulations may not provide optimal dosage.
Please note that I have not said anything about the IM8 longevity supplement. It’s because I’m fed up with longevity trends that are supported by literally nothing. IM8 Ultimate Longevity contains NAD, but it has not been proven to have an effect on human longevity. Nada. It also includes some proprietary blends that we’ve already mentioned. I don’t mean to be extreme, but it’s all garbage.
celebrity effect
I have to mention this, but to be honest, David Beckham has nothing to do with this product as he is a nutrition expert. He’s there because the Trust sells supplements, and consumers naturally assume that if someone as healthy and successful as Beckham makes and uses the product, there must be something special about it. Well, there isn’t. This is a Marketing 101 tactic, so be very careful.
For most healthy adults, I’d rather spend my money on:
Fruits and vegetables Adequate protein strength training Sleep Preventive care See a registered dietitian if needed
These interventions have dramatically stronger evidence than any supplement.
my verdict
No matter how many ingredients a product contains or how healthy and famous its founders are, there is still no evidence that replacing a healthy diet and lifestyle with expensive powders is a shortcut to improving your health.
IM8 is smart marketing involving science that is still much weaker than consumers are led to believe.
