Bloom Nutrition is a supplement brand best known for its greens powder. This page covers what is actually in the products, what the ingredients can reasonably be expected to do, and where the marketing outruns the evidence — including two claims this article previously repeated uncritically.
What Is Bloom Nutrition?
Bloom Nutrition is a US supplement company founded by Mari Llewellyn, selling greens and superfoods powders, pre-workout, whey protein and related products. It grew largely through social media, and its greens powder is among the most visible products in that category.
We have no commercial relationship with the brand and have not tested the products. Figures below come from published nutrition panels and should be checked against the tub you buy, since formulations change.
Greens and Superfoods: The Nutrition Panel
Per 1 scoop (about 6.9g):
| Nutrient | Amount | % Daily Value |
|---|---|---|
| Calories | 25 | – |
| Total Fat | 0.5 g | 1% |
| Sodium | 20 mg | 1% |
| Total Carbohydrates | 5 g | 2% |
| Dietary Fibre | 0.5 g | 2% |
| Sugars | 0.5 g | – |
| Protein | 0.5 g | – |
| Iron | – | ~9% |
The Scoop-Size Reality Check
This is the number that matters most and the one greens-powder marketing never emphasises: a serving is under 7 grams of powder in total.
That 7 grams has to contain every one of the “50+ ingredients” listed on the front. Once you subtract the fibre, flavouring and sweetener, the individual botanical and fruit extracts are present in small quantities — often far below the amounts used in the studies those ingredients are famous for. That is not unique to Bloom; it is how the entire category works.
For comparison, a single 80g serving of actual vegetables delivers more fibre than a scoop of greens powder, at a fraction of the cost. The panel above shows 0.5g of fibre and 0.5g of protein per scoop.
What a greens powder can reasonably do: add some micronutrients, act as a convenient habit, and taste pleasant enough that you drink it. What it cannot do: replace vegetables, or deliver clinically meaningful doses of dozens of botanicals from seven grams of powder.
Two Claims We Have Corrected
- “Natural caffeine from green tea, so no anxiety or insomnia.” This was on the page and it is wrong. Caffeine from green tea is chemically identical to caffeine from any other source, and it affects sleep and anxiety in exactly the same way. The source of caffeine does not change its effects — only the dose, your sensitivity and the timing do. If you are caffeine-sensitive, a “natural” pre-workout will still keep you awake.
- “Detoxifies the digestive system, which prevents bloating.” This was the brand’s claim, repeated here without comment. Your liver and kidneys perform detoxification; “detox” is a marketing idea rather than a physiological one. Some people do report less bloating on greens powders, which is plausible from the fibre and probiotic content — but that is a digestive comfort effect, not detoxification, and it is not universal. Greens powders make some people more bloated, not less.
Pre-Workout
Per scoop (about 5.6g), the published panel lists vitamin C 100mg, vitamin B6 25mg (around 1,470% DV) and vitamin B12 50mcg (around 2,080% DV).
Two things worth understanding about those numbers. Very high B-vitamin percentages are standard in pre-workouts and largely cosmetic — B vitamins are water-soluble and excess is excreted, so 2,000% DV does not give you twenty times the benefit. And the panel above omits the ingredient that actually does the work: caffeine. Check the caffeine content on the tub and count it toward your daily total alongside coffee and tea.
Long-term high-dose B6 supplementation has been associated with nerve problems, so it is worth knowing your total intake if you take several supplements containing it.
Whey Protein
Per scoop (32g): 90 calories, 0g fat, 170mg sodium, 1g carbohydrate, 1g fibre, 22g protein.
This is the most straightforward product in the range. 22g of protein for 90 calories is a good ratio, and unlike greens powders, protein powder does something measurable — it helps you hit a protein target. Judge it on protein per serving and price, the same way you would any whey.
Working Out What It Costs You
Prices change and vary by retailer, so rather than quoting a figure that will be stale: divide the tub price by the number of servings on the label. Greens powders are commonly sold in 30-serving tubs, pre-workout in 40.
Then compare that per-serving cost against what the same money buys in vegetables, or in a plain whey protein. That comparison, rather than the ingredient count on the front, is the useful test.
Who It Suits, and Who Should Check First
- Reasonable fit: people who already eat decently and want a convenient extra, or who genuinely enjoy the routine.
- Poor fit: anyone hoping to replace vegetables, or expecting the powder to fix bloating, energy or immunity on its own.
- Check with a doctor or pharmacist first if you are pregnant or breastfeeding, take medication (greens blends often contain vitamin K, which interacts with warfarin), have kidney disease, or are sensitive to caffeine.
As with any supplement, look for independent third-party testing such as NSF or USP — dietary supplements are not approved by the FDA before they go on sale.
FAQs about Bloom Nutrition
Some people report less bloating, which is plausible from the fibre and probiotic content. Others find greens powders make bloating worse. The brand’s claim that it “detoxifies the digestive system” is not accurate — your liver and kidneys handle detoxification. If bloating is persistent, that is worth discussing with a doctor rather than treating with a powder.
No. Caffeine from green tea is chemically identical to any other caffeine and affects sleep and anxiety the same way. What matters is the dose, your sensitivity and how late you take it — not the source.
No. A scoop is under 7 grams of powder and provides about 0.5g of fibre. A normal portion of vegetables provides considerably more, along with water and volume that help you feel full. Treat greens powder as an addition, not a substitute.
The brand states its greens powder is gluten-free. If you have coeliac disease, check the label on the tub you buy and look for explicit gluten-free certification, since formulations and manufacturing arrangements change.
It was founded by Mari Llewellyn, who built the brand after developing a following around her own fitness and nutrition changes.
