IM8 launched with a David Beckham co-founder credit and a Mayo Clinic and NASA advisory line, which is the kind of marketing that usually signals a thin product behind it. In this case the label is genuinely strong. IM8 uses better vitamin forms than AG1 and includes the Vitamin D that AG1 omits. It also carries the same proprietary blend problem and a celebrity price. Here is the audit.
Why this product has no score: our 10-point score is built to evaluate products intended to replace a meal, and it weights protein, calories and fiber heavily. Running a daily nutrition supplement through that framework would produce a low number that tells you nothing useful, because it is not trying to replace a meal. This review assesses it on what it actually claims to do: fill micronutrient gaps in a diet you are already eating. For scored meal replacements, see how we rank.

The Vitamin Forms Are the Best We Have Audited
This is IM8's real differentiator and it is not what the marketing leads with.
Folate is Quatrefolic, a branded 5-MTHF, the bioactive form. B12 is methylcobalamin. B2 is riboflavin-5-phosphate, the active form, which is uncommon. B6 includes P5P. Magnesium is bisglycinate, among the best absorbed and gentlest on digestion. Vitamin D is VegD3 from lichen, which is vegan-suitable D3 rather than the weaker D2 that most plant-based products settle for. Vitamin K appears as both K1 and K2 as MK-7.
Line that up against the category. Ka'Chava uses folic acid, cyanocobalamin, magnesium oxide and zinc oxide at $4.67 a serving. AG1 has good forms but no Vitamin D at all. IM8 covers the active forms and includes D3.
On vitamin quality alone, IM8 has the strongest panel of any daily nutrition product we have looked at.
It fixes AG1's biggest gap
Worth stating plainly, because these two get cross-shopped constantly. AG1 does not contain Vitamin D. IM8 contains 1,200 to 2,000 IU of vegan D3 alongside K2 MK-7, which is the pairing that actually makes sense for bone and calcium metabolism. If you were choosing between them on completeness, this is the deciding difference.
Where IM8 Falls Short
The blends are large and opaque
The disclosed vitamins and minerals are fully specified, which is good. Beyond that sit several substantial proprietary blends: a raw superfoods, greens, fruits and herbs complex at 4,100mg, a hydration electrolytes complex at 2,500mg, an MSM joint support blend at 1,000mg to 1,500mg, an adaptogens and mushrooms complex at 200mg, and a CRT8 complex.
Across 90-plus ingredients, most of the interesting non-vitamin content is unverifiable. A 200mg adaptogen and mushroom blend split across multiple ingredients is unlikely to deliver a clinically studied dose of any single one, and the label does not let you check.
Ingredient count as a selling point
"90 nutrients" and "replaces up to 16 supplements" are volume claims, not quality claims. Adding a 27th botanical at 10mg does not improve a formula, it improves the marketing copy. IM8's strength is its vitamin forms, and the ingredient-count framing distracts from the genuinely good part.
The advisory credentials need reading carefully
"Developed in collaboration with experts from Mayo Clinic, Cedars Sinai and NASA" describes individual advisors' affiliations. It does not mean Mayo Clinic or NASA endorse or have tested the product. That is a common construction in supplement marketing and it does real work on the reader. Treat it as advisory input, not institutional validation.
Price
$2.61 a serving quarterly and $2.97 monthly puts IM8 in the same bracket as AG1, and the quarterly rate requires committing to a 90-day supply upfront. It is a premium price, though unlike Ka'Chava the label largely justifies it.
IM8 vs AG1
The most common question, so directly:
IM8 wins on formulation. Better vitamin forms overall, riboflavin-5-phosphate and magnesium bisglycinate where AG1 uses standard versions, and critically it includes Vitamin D where AG1 has none.
AG1 wins on evidence. AG1 has published randomized controlled trials on the finished product. IM8 does not have a comparable published program, and its scientific credibility rests on advisory names rather than trials.
Both fail on transparency. AG1 conceals about 75 ingredients, IM8 conceals across 90-plus. Neither lets you dose-check the interesting content.
If you want the better-built formula, IM8. If you want the product with published trials behind it, AG1. Neither replaces a meal.
Who Should Take IM8
It makes sense if you want the most complete vitamin panel in active forms, you specifically want vegan D3 and K2 covered in one product, and you are comfortable with a subscription at this price.
It does not make sense if you want published trials on the finished product, you need verifiable doses on botanicals and adaptogens, or you are looking for anything that replaces a meal. At 20 to 40 calories it is a supplement, full stop.
Frequently Asked Questions
Is IM8 better than AG1?
On vitamin forms and completeness, yes, mainly because it includes Vitamin D. On published clinical evidence, no. Pick based on which of those you weight more.
Did David Beckham actually develop it?
He is a co-founder alongside Prenetics, a NASDAQ-listed biotech. The formulation work sits with the scientific advisory team. Celebrity involvement is a marketing asset and tells you nothing about the label, which in this case happens to be strong anyway.
Is IM8 a meal replacement?
No. 20 to 40 calories and no meaningful protein.
What is VegD3?
Vitamin D3 derived from lichen rather than lanolin, making it suitable for vegans. It is the more effective form compared with D2, which is what most plant-based products use.
Is the quarterly subscription worth it?
It drops the per-serving price from $2.97 to $2.61, roughly 12%, in exchange for committing to 90 days billed upfront. Try a monthly cycle first and confirm you will actually take it daily.
Bottom Line
IM8 is a better formula than the celebrity framing led us to expect, and the best vitamin panel we have audited in this category. Active B vitamins, magnesium bisglycinate, vegan D3 and K2 MK-7 together is a genuinely well-built stack.
It is held back by large opaque blends across 90-plus ingredients, credential-adjacent marketing that implies more institutional backing than exists, and no published trials on the finished product. If your priority is the best forms and complete coverage, it is the strongest option here. Just do not mistake it for food.
