How Much Caffeine Is in OxyShred Thermogenic Fat Burner?

You just unboxed a sleek tub of OxyShred, the neon label promising thermogenic fire and serious energy. The ingredients list is a wall of chemicals, and the one thing you really want to know — the caffeine count — isn’t always front and center. Guessing wrong could mean jitters by noon or an accidental overdose on stimulants.

The research-backed answer is 150 mg per scoop for the standard formula. That’s roughly one and a half cups of coffee squeezed into a single serving of powder — enough to feel a serious lift, but not so much that you’re automatically over the safe daily line. The catch is that OxyShred comes in multiple versions, and the caffeine content climbs sharply depending on which tub you grabbed.

How 150 Mg Compares To Other Caffeine Sources

To make sense of 150 mg, it helps to stack it against familiar drinks and other pre-workouts. A standard 8-ounce cup of brewed coffee delivers roughly 95 mg of caffeine, according to typical USDA data. That means one scoop of OxyShred packs about 60 percent more caffeine than your morning mug.

A typical energy drink like a 16-ounce Monster runs around 160 mg, putting OxyShred’s single scoop in the same ballpark. But OxyShred is a fine powder, not a canned beverage, so it’s easier to accidentally double up — and some users do reach for two scoops out of habit, which pushes the total close to 300 mg.

The FDA considers 400 mg per day a safe upper limit for most healthy adults. A single scoop uses about 38% of that allowance, leaving room for other caffeine throughout the day if you’re tracking your intake carefully.

Why The Caffeine Count Varies By Version

The confusion around OxyShred caffeine starts with EHP Labs’ product line. The standard blue-and-white tub is the entry point at 150 mg per scoop, but the brand sells multiple formulations with very different stimulant profiles. Picking up the wrong tub can double your caffeine without warning.

A separate study on a ready-to-drink product called OxyShred Ultra Energy measured 180 mg of caffeine per serving, according to NIH data. And the manufacturer’s own product listing for OxyShred Hardcore shows a total of 275 mg of caffeine per scoop, derived from a three-source blend of caffeine anhydrous, guarana seed extract, and green coffee bean extract.

• Standard OxyShred (blue tub): 150 mg caffeine per scoop. This is the version most commonly found in supplement stores and used in the peer-reviewed research.
• OxyShred Hardcore (black tub): 275 mg caffeine per scoop. Nearly double the standard version, drawing caffeine from three separate botanical sources.
• OxyShred Ultra Energy (RTD can): 180 mg caffeine per 500 ml can. A liquid format studied for its effects on resting energy expenditure.
• Two-scoop standard serving: Approximately 200 mg total caffeine when using the standard formula at double the recommended single scoop, per some commercial formulation data.

The takeaway is simple: always check the label on the specific tub you bought. If it says OxyShred Hardcore, you’re looking at 275 mg — a dose that alone uses 69% of the FDA’s daily caffeine ceiling.

Where The 150 Mg Figure Comes From

OxyShred contains green coffee bean extract as a natural caffeine source, plus inulin fiber for appetite support and a proprietary thermogenic blend. The caffeine doesn’t come from a single isolated source — it’s the total of several botanical ingredients that each contribute small amounts of stimulant compounds.

A peer-reviewed study published through PMC used OxyShred Thermogenic Fat Burner as the active treatment in its research protocol and confirmed the 150 mg caffeine per serving figure directly from the product label used in the trial. That makes this number the most authoritative benchmark available, stronger than a retailer’s webpage or a forum post.

For context, 150 mg sits comfortably in the moderate range for thermogenic supplements. Many popular fat burners hover between 100 and 200 mg per serving. It’s enough to trigger a noticeable boost in energy and focus, but not so high that it’s automatically risky for a caffeine-tolerant adult.

OxyShred Version	Caffeine Per Serving	% Of FDA Daily Limit
Standard (blue tub)	150 mg	38%
Ultra Energy (RTD)	180 mg	45%
Standard — 2 scoops	~200 mg	50%
Hardcore (black tub)	275 mg	69%
Typical pre-workout (average)	200–300 mg	50–75%

Caffeine content climbs quickly across the product line. If you’re new to thermogenic supplements, the standard 150 mg version is a reasonable starting point — jumping straight to the Hardcore formulation could overwhelm your system.

What Affects Your Personal Tolerance

Caffeine sensitivity varies widely between individuals. Someone who drinks coffee daily may barely notice 150 mg, while a caffeine-naive person could feel anxious and jittery within 30 minutes. Body weight, liver enzyme activity, and even genetics play a role in how long the stimulant effect lasts.

Here are some factors to consider before your first scoop:

1. Your baseline caffeine tolerance: If you regularly consume 200–400 mg daily from coffee or energy drinks, 150 mg is a modest addition. If you rarely use caffeine, start with a half scoop.
2. Timing of the dose: Thermogenic supplements can disrupt sleep patterns. Taking OxyShred too late in the day — especially after 2 PM — may cause insomnia or restless sleep.
3. Empty stomach risk: Some users take OxyShred first thing for maximum effect. Taking it on an empty stomach increases the chance of nausea or gastrointestinal discomfort.
4. Hydration needs: Caffeine has a mild diuretic effect. The manufacturer recommends drinking extra water throughout the day when using the product.
5. Combining with other caffeine sources: If you have coffee, tea, or soda within a few hours of your scoop, the total accumulates quickly toward the 400 mg daily limit.

Individual responses differ, so it’s wise to start low and assess how you feel before adjusting the dose upward.

Safety Signals And Side Effects To Watch For

The majority of OxyShred users tolerate it well, but side effects are reported frequently enough to deserve attention. Some users describe feeling jittery or anxious within the first hour, which is consistent with caffeine’s known effects on the nervous system.

Per the standard OxyShred 150 mg analysis from a commercial supplement retailer, the product delivers about the caffeine equivalent of one and a half cups of coffee. For most healthy adults, that is a moderate amount. But thermogenic supplements also contain other stimulant compounds and herbal extracts that can amplify or lengthen the caffeine experience beyond what coffee alone would produce.

Headaches, increased heart rate, and trouble sleeping are the most commonly reported complaints. In rare instances documented in medical literature, certain “fat burner” supplement ingredients have been linked to more serious outcomes — though those cases involved different products with different ingredient profiles. If you have a history of heart arrhythmia, high blood pressure, anxiety disorders, or are pregnant or breastfeeding, discuss the product with your healthcare provider before use.

Side Effect	Common Trigger Or Context
Jitteriness or anxiety	High caffeine sensitivity; taking on empty stomach
Insomnia or restless sleep	Dosing after early afternoon; stacking with other stimulants
Increased heart rate	Combining caffeine sources; underlying heart sensitivity
Nausea or stomach upset	Empty stomach ingestion; high stimulant dose

The Bottom Line

Standard OxyShred delivers 150 mg of caffeine per scoop — a moderate dose that fits within FDA guidelines for most adults, but the Hardcore version jumps to 275 mg. Your individual tolerance, the specific version in your tub, and what else you consume that day determine whether that scoop feels energizing or overwhelming.

A registered dietitian or your primary care doctor can help assess whether a 150 mg thermogenic supplement fits into your overall caffeine intake and health profile, especially if you take other medications or have any underlying conditions that sensitive to stimulants.
