Bloom Nutrition’s flagship product, Bloom Greens & Superfoods, is a powdered supplement containing a mix of dried greens, fruit and vegetable extracts, digestive enzymes, probiotics, prebiotic fiber, and adaptogens like ashwagandha, all sweetened primarily with stevia. The label lists dozens of individual components grouped into several proprietary blends, which can make it hard to figure out what you’re actually getting and whether any of it does anything meaningful. Understanding both the ingredients themselves and the evidence behind them matters, especially for a product that gained massive popularity through social media rather than clinical trials.
The Greens and Superfoods Blend
The core of Bloom Greens is a mix of dried, powdered plant ingredients. You’ll find organic wheat grass, organic barley grass, spirulina, chlorella, and spinach among the greens. The “superfoods” portion adds fruit and vegetable powders and extracts, including things like beet root, turmeric, rhodiola, and various berry extracts. These are marketed as a convenient way to increase your intake of phytonutrients, the beneficial compounds found in colorful plants.
The appeal of concentrated greens powders rests on the idea that dehydrating fruits and vegetables preserves their nutritional value. Research on this is mixed. A study examining phenolic content in fresh versus dehydrated produce found that retention of phenolics after dehydration ranged widely, from under 40% in spinach to over 90% in some apple preparations. Antioxidant capacity, measured by one common method, dropped even further: retention ranged from about 16% in tomato to roughly 65% in blackberry.1CyTA – Journal of Food. Phenolic content and antioxidant capacity in fresh and dry fruits and vegetables grown in Chile In other words, drying plants preserves some of their beneficial compounds but not all, and the amount retained varies enormously depending on the specific plant and the drying method used.
There’s an important caveat here. Bloom’s label does not disclose the exact amount of each individual greens ingredient because they are grouped into proprietary blends with only a total blend weight listed. You can see the order of ingredients within the blend (listed by weight, highest to lowest), but you cannot tell whether spirulina makes up most of the blend or just a sprinkle. This is a standard practice in the supplement industry, but it limits how much you can evaluate the product against research on specific greens doses.
Digestive Enzymes
Bloom Greens includes a digestive enzyme blend featuring enzymes like amylase, protease, lipase, cellulase, and lactase. The idea is that supplemental enzymes help your body break down food more completely, improving nutrient absorption. Your body already produces these enzymes naturally, but production can decline with age or certain health conditions.
A randomized, placebo-controlled trial in healthy middle-aged and older adults tested a mixture of six enzyme preparations, including proteases, lipase, amylase, and glucoamylase, taken alongside a mixed meal. The enzyme group showed faster absorption of leucine, an amino acid important for muscle, and higher postprandial glucose and fatty acid levels, suggesting the food was broken down more thoroughly. The researchers concluded that multienzyme supplementation improved macronutrient digestion, though the benefit for amino acid absorption was most pronounced in people with lower body fat and higher lean mass, and the effect was sex-dependent.2PubMed Central.

That sounds promising, but keep in mind that this trial used specific enzyme doses tested under controlled conditions, and the participants were older adults whose digestive function had already started declining. If you’re a healthy younger adult, you likely produce plenty of your own digestive enzymes, and the added benefit of supplemental ones may be negligible. People with diagnosed conditions like exocrine pancreatic insufficiency use prescription-strength enzyme supplements, but those are a different animal from what’s in a greens powder.
Probiotics and Prebiotics
Bloom includes a probiotic, and the label lists a colony-forming unit (CFU) count. The product also contains prebiotic fiber, with inulin being a common prebiotic in greens supplements. Prebiotics and probiotics are meant to work together: the prebiotic feeds beneficial gut bacteria, while the probiotic introduces additional live bacteria.
Inulin, when it reaches the colon, is fermented by gut bacteria. This fermentation generates short-chain fatty acids, which serve as fuel for the cells lining the intestine and play a role in regulating immune cell activity.3PubMed Central. Immunomodulatory effects of inulin and its intestinal metabolites Research on inulin supplementation in obese patients has explored links between gut microbiota changes and health outcomes, though untangling cause and effect in these studies remains difficult.4PubMed. Link between gut microbiota and health outcomes in inulin -treated obese patients: Lessons from the Food4Gut multicenter randomized placebo-controlled trial
The probiotic side has its own complications. Getting live bacteria to survive manufacturing, shelf storage, and then the acidic environment of your stomach is a genuine challenge. Processing conditions, temperature, dissolved oxygen, and the acids and enzymes in your digestive tract all threaten probiotic viability, and effective preservation and delivery technologies are needed to keep bacteria alive long enough to do anything useful.5Taylor & Francis Online. Bacterial viability retention in probiotic foods: a review Whether the probiotics in a shelf-stable, room-temperature powder like Bloom survive in meaningful numbers by the time they reach your gut is a real question, and one the label doesn’t answer. Some probiotic strains are hardier than others, and some manufacturers use microencapsulation to protect them, but without independent viability testing of the specific product, you’re taking it on faith.
Ashwagandha and Adaptogens
Ashwagandha is one of the most recognizable adaptogen ingredients in Bloom’s formula. Adaptogens are herbs traditionally claimed to help the body manage stress, and ashwagandha in particular has attracted a fair amount of research in recent years. Bloom uses ashwagandha root extract, which is consistent with the form used in most clinical trials.
A randomized, placebo-controlled trial tested ashwagandha supplementation over eight weeks in healthy adults. Even at a low dose of 30 mg per day, the ashwagandha group showed improvements in cardiorespiratory fitness, with higher VO₂max and maximal heart rate compared to placebo. Participants also had lower lactic acid levels during exercise, suggesting they stayed in aerobic metabolism longer, and reported less fatigue. The supplement was well tolerated, with no treatment-related adverse events and normal results across blood, liver, kidney, and metabolic panels.6PubMed Central. Efficacy and Safety of Low-Dose Ashwagandha Supplementation on Exercise Endurance: A Randomized, Placebo-Controlled, Double-Blind, Clinical Trial
The catch, again, is dosing. Bloom does not disclose the exact milligrams of ashwagandha per serving due to the proprietary blend structure. Clinical studies of ashwagandha typically use doses ranging from 30 mg of highly concentrated extracts up to several hundred milligrams of standard root extracts. Without knowing how much is in your scoop, you can’t compare your intake to what was used in a study that showed results. Ashwagandha also has some interactions worth knowing about: it can affect thyroid hormone levels, and people on thyroid medication or with thyroid conditions are generally advised to consult a doctor before using it regularly.
Sweeteners and Flavoring
Greens powders face a basic palatability problem. Dried spirulina, barley grass, and chlorella taste roughly the way you’d expect: earthy and bitter. To make the product drinkable, Bloom uses a combination of natural flavors, citric acid, and stevia leaf extract as a zero-calorie sweetener. Some formulations also include coconut water powder and fruit juice powders that contribute both flavor and mild sweetness.
Stevia has been a subject of interest not just as a sweetener but for its effects on the gut. Research into how stevia consumption affects gut bacteria has found a potential benefit on microbial diversity, though the effects appear to depend on how much stevia is consumed, how often, and what else is in the diet.7PubMed Central. The Effects of Stevia Consumption on Gut Bacteria: Friend or Foe? Unlike some artificial sweeteners that have been flagged for potentially disrupting the microbiome, stevia seems to be relatively neutral to mildly positive in this regard, at least based on what’s been studied so far. That said, the amounts of stevia in a daily serving of Bloom are small, and the practical gut-health impact of that quantity specifically is unknown.
Bloom Greens contains no added sugar, and the calorie count per serving is very low, typically around 15 to 25 calories depending on the flavor. The product is also marketed as being free of soy, gluten, and dairy, though “processed in a facility that also handles” disclaimers apply if you have severe allergies.
What the Research Says About Greens Powders Overall
Individual ingredients in Bloom have varying levels of evidence behind them, but what about greens powders as a category? The honest answer is that rigorous, large-scale clinical trials on branded greens supplements are scarce. One of the few published trials tested a different greens product and found that users scored marginally higher on vitality compared to placebo, and significantly higher on self-reported energy, though the researchers themselves described the findings as “positive but not conclusive.”8PubMed. Effects of greens+: a randomized, controlled trial That study wasn’t on Bloom specifically, and the formulations differ, but it’s representative of what the evidence looks like across the greens powder market: small trials, modest effects, and a lot of room for placebo effects to drive self-reported outcomes like “energy” and “vitality.”
The bigger picture is that no greens powder replaces actual fruits and vegetables in your diet. Whole produce contains fiber, water, and a full matrix of nutrients that interact with each other in ways a concentrated powder cannot replicate. The dehydration process, as noted earlier, loses a meaningful share of the original antioxidant and phenolic content. A greens powder might be a reasonable supplement on days when your vegetable intake is genuinely poor, but treating it as an equivalent trade for a salad or a bowl of berries overstates what the product delivers.
The Regulatory Landscape for Supplements Like Bloom
Bloom Nutrition is classified as a dietary supplement in the United States, which means it falls under a different regulatory framework than drugs or conventional foods. Under the Dietary Supplement Health and Education Act, supplements are regulated as foods through the FDA. The manufacturer is responsible for ensuring the product is safe and that label claims are truthful, but the FDA does not approve supplements for safety or effectiveness before they go to market. The law also established labeling requirements and Good Manufacturing Practice guidelines to ensure that preparation, packaging, and storage meet certain standards for purity, composition, and strength.9PubMed Central. Current regulatory guidelines and resources to support research of dietary supplements in the United States
What this means in practice is that Bloom can list its ingredients and make certain structure/function claims (“supports digestion,” “promotes energy”) without needing to prove those claims the way a pharmaceutical company would need to prove a drug works. You’ll notice that supplements carry a disclaimer: “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.” That disclaimer isn’t just legal fine print; it’s a signal that the health claims on the label haven’t been independently verified by regulators.
Third-party testing is one way consumers can get more assurance about what’s actually in a supplement. Organizations like NSF International and USP offer voluntary certification programs that verify whether what’s on the label matches what’s in the product, and whether the product is free of contaminants. Not all supplement brands opt into these programs, and checking whether a product carries a third-party certification mark is one of the more practical steps you can take as a consumer.
Why Bloom Got So Popular
It’s worth understanding that Bloom Nutrition’s rise was driven less by clinical evidence and more by social media marketing. Research into Bloom’s marketing strategy has shown that the brand relies heavily on lifestyle influencers on TikTok, who incorporate the product into their regular content. The strategy is essentially product placement: influencers mix the powder into their morning routines, film it, and the product gets associated with their curated healthy lifestyle. The brand uses influencers’ physical appearances to advertise the product while promoting a broader health and wellness narrative.10Carleton University Institutional Repository. #Bloompartner: The use of Influencer Marketing in the Growth of Health and Wellness Products
This matters because marketing reach and product effectiveness are entirely separate things. A product can go viral on TikTok and still have a thin evidence base. The influencers promoting Bloom are typically not nutrition scientists; they’re content creators with large followings and sponsorship deals. When someone with a million followers stirs Bloom into a glass of water and says they feel amazing, that’s a testimonial, not data. The popularity of the product is a reflection of effective branding, not validated health outcomes.
Common Misconceptions and Practical Considerations
One of the most persistent myths around products like Bloom is that they “detox” your body. Your liver and kidneys already handle detoxification, and no supplement removes toxins that your organs can’t handle. Bloom’s label, to its credit, doesn’t use the word “detox,” but the broader greens powder market leans into that language, and many consumers come to these products expecting a cleanse. If a greens powder helps you feel better, the explanation is more likely improved micronutrient intake or the placebo effect than any detoxification mechanism.
Another common confusion involves the difference between proprietary blends and transparent labels. A proprietary blend tells you which ingredients are in the product and the total weight of the blend, but it doesn’t tell you how much of each individual ingredient you’re getting. This is perfectly legal, but it makes dose comparisons to clinical research nearly impossible. Some competing greens powders have moved toward fully transparent labels that list every ingredient with its exact dose. If being able to compare your intake to studied doses matters to you, those products may be worth considering.
If you’re thinking about starting Bloom, a few practical notes. Greens powders can cause bloating and gas when you first start using them, especially if you’re not used to inulin or other prebiotic fibers. Starting with half a serving and increasing gradually helps. The product should be mixed into cold or room-temperature water; hot liquids can degrade both the probiotics and some of the more heat-sensitive plant compounds. And if you’re pregnant, nursing, taking prescription medications, or managing a chronic health condition, talk to your doctor before adding any supplement to your routine.
What Bloom Doesn’t Contain
Sometimes what’s absent from a product tells you as much as what’s in it. Bloom Greens does not contain significant amounts of protein, fiber, or calories. A single serving has a trivial amount of each, which makes sense given that you’re adding a small scoop of powder to water. It’s not a meal replacement and shouldn’t be treated as one. It also doesn’t contain the full spectrum of vitamins and minerals you’d find in a multivitamin; some formulations include added B vitamins or iron, but the amounts vary by product line and flavor.
The product is also free of caffeine in most formulations (Bloom sells separate energy-focused products that do contain caffeine). It doesn’t contain creatine, beta-alanine, or other sports-performance compounds found in pre-workout supplements. If you’re looking at Bloom as a performance aid, the ashwagandha is really the only ingredient with direct exercise-related evidence, and even that depends on whether the dose in Bloom is sufficient to match what was used in trials. For someone who just wants a convenient way to add some plant-derived nutrients to an otherwise decent diet, the product fills a narrow niche. For someone expecting dramatic health transformations, the evidence simply isn’t there to support that expectation.
