OPA Oxy-Charge (formerly sold as Oxy-Burn) is a stimulant capsule. It's built around caffeine, plus glucomannan, green tea extract, raspberry ketones, yohimbe, kola nut and L-carnitine, and a 60-capsule bottle is $29.99. This guide covers what's in each blend, what the research says about each ingredient, and who should skip it. It's a stimulant, so it isn't for everyone.
Key Takeaways
- Oxy-Burn is now called OPA Oxy-Charge. The formula is the same, and the old product link points to the new page.
- Each capsule has three proprietary blends, so the exact caffeine and yohimbe amounts aren't listed.
- Caffeine reliably raises alertness. For the other ingredients, human evidence at these amounts is limited.
- Yohimbe carries safety warnings from the NIH. Skip this product if you have a heart condition, high blood pressure or anxiety, or if you take antidepressants.
- Take one capsule in the morning, never more than two in 24 hours, and none after 4 PM.
What's in each capsule
| Blend (per capsule) | Amount | Ingredients |
|---|---|---|
| Energy & Focus Blend | 425 mg | Caffeine anhydrous, phenylethylamine HCl, glucomannan |
| Botanical Blend | 40 mg | Raspberry ketones, yohimbe powder, green tea extract |
| Metabolic Blend | 7 mg | Kola nut, L-carnitine base |
Other ingredients: gelatin, rice flour, magnesium stearate, silicon dioxide, FD&C Red #40 and titanium dioxide.
Because these are proprietary blends, the caffeine per capsule isn't listed. If you also drink coffee, tea or energy drinks, keep that in mind. The FDA cites 400 mg of caffeine a day as an amount not generally linked to harmful effects in healthy adults.
What the research says about each ingredient
- Caffeine: It reliably raises alertness. The NIH Office of Dietary Supplements (ODS) notes that people build a tolerance to it.
- Glucomannan: This is a soluble fiber from konjac root. Studies usually use 2 to 4 grams a day, which is far more than fits in one capsule.
- Green tea extract: ODS and the NIH LiverTox database note rare reports of liver problems with concentrated extracts. Stop and see a doctor if you notice dark urine, yellowing skin or stomach pain.
- Raspberry ketones: Most of the research is in animals or lab studies, not people.
- Yohimbe: NCCIH says there isn't enough reliable evidence for any use. It also reports links to heart attacks, seizures, high blood pressure and a rapid heart rate.
- Phenylethylamine (PEA): There's very little human research on it.
- L-carnitine: Studies use 1 to 3 grams a day. The 7 mg blend here is a small fraction of that.
Who it may suit
- Healthy adults who already handle caffeine well and want a capsule instead of coffee
- People who see it as a stimulant for energy and focus, not a shortcut on diet or exercise
Who should skip it or ask a doctor first
- Anyone with high blood pressure, heart rhythm problems, heart disease, anxiety or a seizure history
- People taking antidepressants (especially MAOIs), blood pressure medicine, other stimulants or other caffeine products
- Anyone pregnant or breastfeeding, and anyone under 18
- Anyone with liver disease
- People who are sensitive to caffeine or have trouble sleeping
- Anyone avoiding gelatin or artificial colors (Red #40 is listed)
Price per day
At $29.99 for 60 capsules, it's about $0.50 a day at one capsule.
