Bloom Nutrition
High Energy Pre-Workout
Our analysis — editorial take, not from the label
Markets itself as a clean, women-founded pre-workout, but two proprietary blends mean 220mg is the only active-ingredient amount disclosed on the label — the citrulline, beta-alanine, and beet root amounts are folded into an undisclosed 4.68g blend.

Cautions
- 220mg caffeine (about two cups of coffee) sits inside a 1.26g proprietary blend; the other blend ingredients (tyrosine, theanine, rhodiola, ginseng, huperzia) have no individual doses disclosed.
- The 4.68g Performance Blend contains an undisclosed beta-alanine amount, so tingling/flushing intensity is unpredictable.
- Sweetened with sucralose and acesulfame potassium, not sugar.
Formulated for healthy adults — not intended for anyone under 18. Performance studies use roughly 3–6 mg of caffeine per kg of body weight, which puts 220 mg at the studied amount for a 37–73 kg adult. Full health & safety notes
Product details
Where this label sits
Bloom Nutrition High Energy Pre-Workout sits in the moderate stim tier of the Scoop Sense pre-workout database, which spans 0–400 mg of caffeine per serving. The label uses at least one proprietary blend, so a blend total stands in place of the individual amounts inside it. It runs 30 servings per container at the full labeled serving. Everything on this page comes from the manufacturer's supplement facts panel as of July 2026 — never from the marketing page.
Key ingredients & studied doses
- Performance Blend (L-Citrulline Malate, L-Citrulline, Beta Alanine, Beet Root Extract) · 4.68 g blend. This is a proprietary blend — the label discloses a combined 4.68g weight but not each ingredient's individual amount, so the citrulline and beta-alanine doses can't be compared to the amounts used in published pump or endurance studies.
- Green Tea Leaf Extract (Caffeine) · 220 mg caffeine. The only stimulant amount printed on the panel; roughly two cups of coffee worth of caffeine, sourced from green tea rather than synthetic anhydrous caffeine.
- Clean Energy & Focus Blend (L-Tyrosine, L-Theanine, Rhodiola, Asian Ginseng, Huperzia serrata) · 1.26 g blend (includes the 220 mg caffeine above). Beyond the disclosed caffeine figure, the remainder of the 1.26g is split among five more ingredients with no individual doses listed, so their contribution can't be judged against research amounts.
Flavors & sweetener
Available in flavors such as Sour Peach Ring, Raspberry Lemonade, Sour Gummy, and Bahama Mama, sweetened with sucralose and acesulfame potassium rather than sugar.
Who it's best for
Most regular gym-goers — the caffeine dose is in the range of about two cups of coffee. Skip it if you want every individual dose disclosed on the label. Derived from the label figures above — not medical advice.
How we log this label
Every entry is built the same way: we read the current supplement facts panel, log each disclosed dose, compare it against the amounts used in published research, flag proprietary blends, and state the cautions plainly. The full methodology explains each step.
This label against the research
How we evaluate labelsEach bar shows the amount commonly used in published human research, and where this label's dose falls against it. Research amounts are context, not a recommendation — they are not doses, and nothing here is medical advice.

Beta-alanineundisclosed
This label does not state beta-alanine on its own — it sits inside “Performance Blend (L-Citrulline Malate, L-Citrulline, Beta Alanine, Beet Root Extract)”, disclosed only as a combined 4.68 g blend. A combined total is not a dose of anything named inside it, so there is nothing here to compare against the research. Studied amounts run 3.2 g to 6.4 g.
Source: Rezende et al., Frontiers in Physiology 2020 — “It seems that substantial amounts of BA are required to increase MCarn, with most studies using doses of ~3.2–6.4 g·day−1, for periods ranging from 4 to 24 weeks.”
-
Citrullineundisclosed
This label does not state citrulline on its own — it sits inside “Performance Blend (L-Citrulline Malate, L-Citrulline, Beta Alanine, Beet Root Extract)”, disclosed only as a combined 4.68 g blend. A combined total is not a dose of anything named inside it, so there is nothing here to compare against the research. Studied amounts run 6 g to 8 g.
Source: Gough et al., European Journal of Applied Physiology 2021 — “The most commonly employed dose of CM is a single acute 8 g dose”

Performance studies most often use 3–6 mg per kg of body weight, which works out to roughly 200–400 mg for most adults. The FDA cites 400 mg a day as an amount not generally associated with negative effects in healthy adults.

L-theanineundisclosed
This label does not state l-theanine on its own — it sits inside “Clean Energy & Focus Blend (L-Tyrosine, L-Theanine, Rhodiola, Asian Ginseng, Huperzia serrata)”, disclosed only as a combined 1.26 g blend (includes the 220 mg caffeine above). A combined total is not a dose of anything named inside it, so there is nothing here to compare against the research. Studied amounts run 100 mg to 200 mg.
Source: Payne et al., Nutrition Reviews 2025 — “In theanine-only, low-caffeine, or caffeine-free interventions, the median theanine dose was 200 mg (IQR, 100.45-212.5).”
-
L-tyrosineundisclosed
This label does not state l-tyrosine on its own — it sits inside “Clean Energy & Focus Blend (L-Tyrosine, L-Theanine, Rhodiola, Asian Ginseng, Huperzia serrata)”, disclosed only as a combined 1.26 g blend (includes the 220 mg caffeine above). A combined total is not a dose of anything named inside it, so there is nothing here to compare against the research. Studied amounts run 2 g to 2 g.
Source: Colzato et al., Frontiers in Behavioral Neuroscience 2013 — “In separate sessions participants were exposed to either an oral dose (powder) of 2.0 g of l-Tyrosine (TYR)”
One or more amounts on this label sit inside a proprietary blend, so the individual doses behind the blend total cannot be compared at all.
Common questions about Bloom Nutrition High Energy Pre-Workout
How much caffeine is in Bloom Nutrition High Energy Pre-Workout?
220 mg per full labeled serving — roughly 2.3 small cups of coffee. Within the Scoop Sense pre-workout database (0–400 mg per serving) that places it in the moderate stim tier. The FDA cites about 400 mg per day as an amount generally not associated with negative effects in healthy adults, and coffee, tea, and energy drinks count toward the same total.
Why does Bloom Nutrition High Energy Pre-Workout make my skin tingle?
The 4.68 g blend of beta-alanine. The prickling (paresthesia) in the face, neck, and hands is generally considered harmless, is dose-dependent, and fades on its own — typically within about an hour. Most beta-alanine studies use 3.2 g per day.
What does the proprietary blend in Bloom Nutrition High Energy Pre-Workout hide?
The Performance Blend (L-Citrulline Malate, L-Citrulline, Beta Alanine, Beet Root Extract) lists 4.68 g blend as a combined total. A blend total tells you the sum of its ingredients, not the individual doses inside it — which is why blend entries can't be checked against studied amounts.
