Grüns turned daily nutrition into a gummy and got the vitamin forms right, which is not what we expected. Methylated folate, methylcobalamin, K2 as MK-7, real D3. The catch is what makes a gummy a gummy: 8g of sugar per daily serving, all of it added. That is the whole review in two sentences, but the details matter. Here they are.
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 Better Than They Need to Be
Gummy vitamins are usually where formulation quality goes to die. Cheap forms, low doses, and sugar doing the heavy lifting. Grüns did not do that.
Folate is L-5-MTHF, the bioactive form. B12 is methylcobalamin. B6 is P5P. Vitamin D is real D3 at 800 IU, which is a meaningful dose rather than a token one. Vitamin K2 is MK-7 at 120mcg, which is notably higher than AG1's roughly 29.5mcg and much closer to studied levels. Zinc is citrate.
That is a better panel than most meal replacement shakes costing three times as much. Credit where it is due.
Two weaker positions: iron as ferrous fumarate, which is a common choice but harder on digestion than bisglycinate, and selenium as sodium selenite rather than selenomethionine.
6g of fiber is genuinely useful
More fiber than Huel's 7g per meal on a per-calorie basis, and more than most shakes in the category deliver. It comes largely from tapioca fiber and organic inulin. Inulin is a real prebiotic, though it causes bloating in some people, so start with a smaller portion.
The Sugar Problem
8g of added sugar per daily serving. That is the trade-off for making nutrition taste like candy, and it deserves a clear-eyed look.
For context, that is more added sugar than any meal replacement we have audited. Shakeology, which we criticize heavily for it, has 5g. Soylent has 9g. Grüns sits at 8g and delivers 50 calories and no protein alongside it.
Is 8g catastrophic? No. It is roughly two teaspoons, and current guidance puts a reasonable daily ceiling near 25g to 36g. But it is not nothing, it is a daily habit by design, and if you are managing blood sugar or actively reducing added sugar this is a poor vehicle for a multivitamin.
Grüns offers a sugar-free variant. If the vitamin forms are what attracted you, that is the more sensible version and worth checking the panel on directly.
Zero protein
Worth being explicit since this site is about meal replacements. Grüns has no protein at all. It is a multivitamin in gummy form with fiber and a greens blend. It does not replace anything you eat.
Transparency
Vitamins and minerals are individually disclosed with amounts and forms, which is more than AG1 or IM8 manage.
The Core Nutrients Blend at 8,670mg is where the disclosure stops. Every organic fruit, vegetable, mushroom and greens ingredient sits in that single figure, and Grüns markets heavily on that list: kale, spinach, spirulina, acai, shiitake and dozens more. A blend of that size split across 30-plus whole-food powders means small amounts of each, and there is no way to check.
Whole fruit and vegetable powders in a gummy are a garnish on top of the vitamin panel, not a serving of vegetables. Treat the produce list as marketing and the disclosed vitamins as the actual product.
The Clinical Study
Grüns cites a 12-week double-blind, randomized, placebo-controlled study in 120 healthy adults aged 23 to 59, reporting increased absorption of folate and vitamin C.
That is a real study design and more than most competitors run. Read the claim precisely though: it measured nutrient biomarkers, meaning it showed the vitamins are absorbed. That is a reasonable thing to demonstrate and a low bar. It is not evidence of a health outcome, and the "35,000+ studies" figure elsewhere on the site refers to the broader literature on the ingredients, not research on Grüns.
Value
From about $1.07 a serving on subscription, following a permanent price cut, Grüns is the cheapest product discussed here by a wide margin. AG1 is $2.63 and IM8 is $2.61.
For a well-formed vitamin panel with real D3, high-dose K2 and methylated B vitamins, that is good value. You are paying a third of the price of AG1 for arguably better-disclosed vitamin content, and accepting 8g of sugar and no research program on the finished product beyond the absorption study.
Who Should Take Grüns
It makes sense if you want a well-formulated multivitamin you will actually remember to take, you like the format, you want strong K2 and D3 coverage, and 8g of daily added sugar fits your diet. Or if you take the sugar-free version.
It does not make sense if you are managing blood sugar, actively cutting added sugar, expecting the produce blend to replace vegetables, or looking for anything that substitutes for a meal.
Frequently Asked Questions
Is 8g of added sugar a dealbreaker?
Depends on your diet. It is about two teaspoons daily. If the rest of your intake is low in added sugar it is manageable. If you are managing blood sugar or cutting sugar, choose the sugar-free version or a capsule multivitamin.
Do Grüns replace eating vegetables?
No, and this is the most important thing to be clear about. The organic produce sits inside one 8,670mg blend across dozens of ingredients. It is a small amount of each. You still need to eat vegetables.
Are Grüns better than AG1?
On disclosed vitamin content, arguably yes, and they include Vitamin D and more K2 at a third of the price. AG1 has the published research program and no added sugar. Different trade-offs.
Are they safe for kids?
Grüns sells a separate kids version with adjusted dosing. Do not give the adult product to children, and check with a paediatrician first.
Will the inulin cause bloating?
It can, especially early on. Inulin is a fermentable prebiotic fiber and 6g is a decent amount. Start with half a pack for a week if you are sensitive.
Bottom Line
Grüns is a better-formulated product than the gummy format suggests. Methylated folate, methylcobalamin, real D3, K2 MK-7 at 120mcg, 6g of fiber, individually disclosed vitamin amounts, and about a third of AG1's price.
The 8g of added sugar is the real cost, and the whole-food produce blend is marketing rather than a serving of vegetables. If you want the vitamin panel without the sugar, look at the sugar-free version. And do not confuse any of this with food: 50 calories and zero protein replaces nothing.
