IM8 is a polished, premium take on the all-in-one daily drink, with a 90-ingredient Essentials formula, a separate longevity product and NSF Certified for Sport testing. The celebrity backing gets attention, but the clinical advisors and certification are the more meaningful signals. Price is the main barrier.
What we like
- NSF Certified for Sport and third-party tested
- Daily Ultimate Essentials Pro packs 90 ingredients into one sachet
- Developed with a Mayo Clinic physician and a former NASA chief scientist
- Pre-measured sachets are convenient for travel
- Up to 90 days of money-back cover on quarterly plans
Keep in mind
- Among the most expensive daily supplements in the category
- Longevity claims rest on emerging research
- Mixed reviews on taste, which is berry with an earthy edge
- Some users report mild bloating in the first week
IM8 Health entered the daily-supplement market with a lot of attention, largely because David Beckham is its co-founder. Behind the headline, the brand has assembled a scientific advisory team that includes Dr. Dawn Mussallem, a Mayo Clinic physician, and James Green, a former NASA chief scientist, and it sells two core products: a broad daily nutrition sachet and a separate longevity formula.
We looked past the celebrity angle to the formulas, the testing, the pricing and the guarantee. The question for most buyers is simple: is IM8 meaningfully better than other all-in-one greens and nutrition drinks, or just more expensive?
What IM8 sells
IM8 keeps its range tight, with three ways to buy:
- Daily Ultimate Essentials Pro, the flagship, is a single daily sachet containing around 90 ingredients, including 13 vitamins, 9 minerals, probiotics, prebiotics, rhodiola, mitochondrial support ingredients, electrolytes and superfoods. It has a berry flavor with an earthy undertone.
- Daily Ultimate Longevity is a separate formula built around what the brand calls the hallmarks of aging. It includes an NAD-support complex, curcumin, resveratrol, pterostilbene and spermidine, ten compounds in total.
- The Beckham Stack combines both for people who want the full routine.
Everything comes in pre-measured sachets, which avoids scoops and makes it easy to throw a day's serving into a bag. New subscribers receive a welcome kit with a shaker and information about the formulas.
Testing and the science team
IM8's strongest quality signal is NSF Certified for Sport status, the same independent certification held by AG1. It involves testing for contaminants and banned substances and regular audits, which makes it a meaningful benchmark in a loosely regulated category. The brand also says its products are third-party tested for purity and potency and that formulas are grounded in peer-reviewed research, including a 12-week randomized controlled trial it cites.
Brand-reported results, such as the share of users who say they had more energy or better digestion after a few weeks, come from the company and are not independently verified. The longevity ingredients are the subject of active research, but evidence in humans is still developing, so it is wise to treat claims about slowing aging as hypotheses rather than established outcomes.

IM8 versus AG1 and other all-in-ones
The most natural comparison is AG1. Both are NSF certified, both pack dozens of ingredients into a daily serving, and both target people who want to consolidate supplements. IM8's differences are its sachet-only format, its slightly larger ingredient list and the option of a separate, dedicated longevity product.
On price, IM8 is at the top of the market. The Essentials Pro subscription starts at about $78 per month, roughly $2.61 per day, with Longevity at about $104 per month and the full Beckham Stack at about $183 per month. Simpler greens blends and gummies cost considerably less, so the question is whether you value the extra breadth and certification enough to pay the premium.
What to buy first
For almost everyone, Daily Ultimate Essentials Pro is the right starting point. It covers the broad nutritional bases and is the product most users mean when they talk about IM8. Take it once a day, mixed with water, and give it at least a few weeks before judging.
Add Daily Ultimate Longevity only if you are specifically interested in longevity-focused compounds and are comfortable with the cost. If you already take resveratrol, NAD precursors or curcumin separately, compare doses to avoid doubling up.
The Beckham Stack makes sense for people who have already tried both and want to simplify ordering.
Subscriptions, shipping and the guarantee
IM8 is sold mainly on subscription, with savings of up to 30% shown on its plans and free shipping included. The guarantee is one of the better ones in the category: quarterly plans come with a 90-day money-back guarantee, while monthly plans carry a 30-day guarantee. If you are on the fence, choosing a quarterly plan gives you more time to decide, though it means paying for three months upfront.
Check the renewal terms when you sign up so you know how to pause or cancel before the next billing date.
Tips for getting started
If you decide to try IM8, a few habits make it easier to judge whether it is working for you:
- Audit what you already take. Essentials Pro covers a broad range of vitamins and minerals, so a separate multivitamin may become redundant. Taking both can push some nutrients, such as vitamin A or zinc, higher than you need.
- Take it at the same time every day. Most people prefer the morning, with a glass of cold water. Consistency matters more than timing.
- Ease in if your gut is sensitive. Some users start with half a sachet for the first few days to reduce bloating as the body adjusts to added probiotics and fiber.
- Track a few simple markers. Energy in the afternoon, digestion and sleep quality are easy to note in a phone diary and give you something concrete to compare after a month.
If you have recent blood work, sharing the ingredient list with your doctor can also help you decide whether a broad daily formula fills a real gap.
What users report, who it suits and our verdict
Commonly reported positives include steadier energy without a caffeine crash, better regularity, sharper focus and the convenience of a single sachet. Commonly reported negatives are the price, a taste that not everyone enjoys, and mild bloating or digestive changes during the first week, which is typical when adding probiotics and fiber.
IM8 suits busy adults, frequent travelers and people already spending a lot on separate supplements who want to consolidate into one premium, certified product. It is a poor fit for budget-conscious buyers, people who prefer single-ingredient supplements with full dose control, and anyone who is pregnant or on medication without medical advice.
Our verdict: IM8 is a serious, well-certified product rather than a celebrity novelty. Essentials Pro is a credible alternative to AG1 for people who prefer sachets and a broader formula, and the guarantee lowers the risk of trying it. The longevity product is more speculative. If the price fits your budget, start with Essentials Pro on a quarterly plan and see how you feel.
