Is OxyShred a fat burner? One serving, 23 women, 180 minutes
Is OxyShred a fat burner? It is sold as one. Its published trial gave one serving to 23 women for 180 minutes and reports calories burned, not fat lost.
Is OxyShred a fat burner? It is sold and formulated as one: a thermogenic powder built on caffeine, acetyl L-carnitine and plant extracts. The published trial this desk found naming it reported resting calorie burn up 121 to 166 kcal/day after one serving, measured over 180 minutes in 23 women. Fat loss is not among the outcomes its abstract lists.
This desk read EHPlabs’ OxyShred clinical trial page, its product page and label and the trial abstract (Journal of the International Society of Sports Nutrition, 2023) on 18 October 2026.
What did the OxyShred clinical trial measure?
Researchers at the University of Mary Hardin-Baylor and Texas Tech University gave 23 female college students (BMI 25 to 32.5, moderate caffeine users) one serving and a placebo on separate days, double-blind, after a 12-hour fast.
| Outcome | After one serving, per the abstract |
|---|---|
| Resting energy expenditure | Up 121–166 kcal/day at 30, 60 and 180 min |
| Systolic blood pressure | Up 3–4 mmHg at 30, 120 and 180 min |
| Free fatty acids | Up at 60 and 180 min |
| Fatigue | Down |
| Fat mass or body weight | Not among the outcomes listed |
On placebo, resting energy expenditure fell 72 to 91 kcal a day.
The product page calls OxyShred “scientifically proven” to raise caloric expenditure. The brand’s trial page says the result “does not confirm long-term weight loss” and names the tested product OxyShred Ultra Concentration.
How much caffeine is in OxyShred?
Its active blends are printed as totals only. Caffeine anhydrous sits in an 851 mg “Mood Enhancer Matrix” with L-tyrosine, taurine and huperzine A. Acetyl L-carnitine, CLA, raspberry ketones, bitter orange and green coffee bean extract share a 2,003 mg “Shredding Matrix”. Caffeine per scoop cannot be read off it. The FAQ credits caffeine with L-theanine; the ingredient list names no theanine.
Twice a day, tested once
The directions say twice daily for optimum results. The trial tested one serving. See our 21-study fat burner review and caffeine’s trials in milligrams; our OxyElite panel review does the same arithmetic on another stimulant.
Questions readers ask
Will I build a tolerance to OxyShred?
EHPlabs’ own FAQ says the body may adapt because OxyShred contains caffeine, and recommends a one-week break after each tub, especially after about four weeks of consistent use. The 2023 trial gave one serving on one day, so it says nothing about tolerance.
Is OxyShred vegan?
The brand says OxyShred contains no animal-based ingredients but is not officially certified vegan, because EHPlabs products are made in a facility that also processes whey protein. The same FAQ names the sweetener as sucralose, which it says has been evaluated for safety for decades.
How effective is OxyShred for fat loss results?
Neither the trial abstract nor the brand’s trial page read here reports a fat-loss result. The 2023 trial measured resting energy expenditure, heart rate, blood pressure, blood markers, hunger and mood for three hours after a single serving, and nothing longer.
The small print, meant
Nothing here promises an outcome, and weight is not a moral matter. These statements have not been evaluated by the Food and Drug Administration, no supplement is a substitute for medical care, and anyone on medication, pregnant or sensitive to stimulants should ask a clinician first.
