Caffeine in Workout Supplements

caffeine-workout-supplementsWorkout Supplements can be a great way to help athletes get those few extra reps in at the gym.

Most of them make some extraordinary claims like “massive gains” and “extreme endurance”, however, we aren’t going to address the accuracy of those claims, but instead, focus on the caffeine content.

Most workout supplements contain a large dose of caffeine as one of the main active ingredients, which is primarily responsible for any “energy rush” experienced by the consumer.

The Most Caffeinated Pre-Workout Supplement?

Of the pre-workout products we’ve been able to track in the list above, Mr. Hyde by Pro Supps comes out as the leader.

Its 419 milligrams of caffeine per serving is from 3 different variations of caffeine.

  • Caffeine Anhydrous– The “typical” caffeine source found in most products.
  • Dicaffeine Malate- This is a combination of caffeine and malic acid. It is reported to be easier on the stomach and faster acting than caffeine anhydrous.
  • Caffeine Citrate– Caffeine is combined with citric acid in this version, which causes it to have faster results. This version has been used to treat asthma and severe migraines.
  • Caffeine Pterostilbene Cocrystal – Combining caffeine with Pterostilbene (a naturally occurring compound in blueberries) causes the caffeine to be released more slowly into the bloodstream over time.

Be careful with Mr. Hyde, never take more than the recommended dose and consider other caffeine sources you may be consuming.

Proprietary Blends

proprietary-blendMost of the workout supplements that we researched disguise the exact amounts of their active ingredients with the term proprietary blend. This simply is to prevent competitors from knowing exactly what their formulas are.

However, this isn’t very good for the consumer. Luckily, many of the brands have begun at least disclosing the caffeine content in their secret blends like the ones listed above.

With some other popular brands it’s still a mystery. Brands like MusclePharm, Animal Rush, SuperPump, Black Powder, HemoRage, Muscle Warefare, and Bull Nox still do not disclose how much caffeine is in their products.

Props to Cellucor for clearly displaying their caffeine content on all of their labels.

Too Much Caffeine?

With many of these products delivering 300mg of caffeine/serving, users should be cautious.

Pre-workout supplements made our Most Dangerous Caffeinated Products List as the 3rd most dangerous!

Especially if other caffeinated beverages or products are also being consumed during the same day such as coffee, tea, soda, and/or energy drinks.

It’s important for consumers to be aware of how much caffeine they’re consuming daily while using workout supplements. People with certain heart conditions, woman who are pregnant, or those sensitive to caffeine should be extremely cautious when using these supplements.

The DMAA Warning

Some of the workout supplements above may have once contained DMAA. This substance has been banned by the FDA who says the following:

DMAA, also known as 1,3-dimethylamylamine, methylhexanamine or geranium extract, is an ingredient found illegally in some dietary supplements and often touted as a “natural” stimulant. DMAA, especially in combination with other ingredients such as caffeine, can be a health risk to consumers. Ingestion of DMAA can elevate blood pressure and lead to cardiovascular problems ranging from shortness of breath and tightening in the chest to heart attack. Dietary supplements containing DMAA are illegal and FDA is doing everything within its authority to remove these products from the market.

While most of these products are off the shelves, they could still exist online or in products that may have been sitting around awhile. Consumers should double check the label before consuming any workout supplement.

  • Arthz

    Hi ted i want to try the buzz preworkout from

  • Arthz

    Ehp lab , is it safe ?

  • Ted

    Which of their products are you referring to?

  • coodyscoops

    Me too with mr. hyde if i just drink a quarter of the 8 ounces or water its mixed with it can take me a long way… and it tastes great

  • Danny Zuehlsdorf

    Very useful info here. Keep it up! Looking for caffeine content in Cutler Nutrition LEGEND. Is anyone pushing for companies to be required by law to disclose the amount of caffeine in their products?

  • Ted

    Hi Danny, thanks, we will. I just put in a quick call to them and they won’t disclose. Their day is coming as the FDA is cracking down on this practice. My best guess would be 300 mg of caffeine per scoop since they state “as much as 2 cups of coffee”. I would advise you to vote with your wallet and only buy products from companies that do disclose.

  • Nick Kaplafka

    I took bullnox and have worst head throbbing pain what can I do?

  • Mikey Bav

    C4 is by far my favorite. http://amzn.to/1Ku1rjK I think that it has the cleanest pre workout effect and I do not get jittery or any head problems.

  • Update: 08.17.2015 // We just released an improved version of Amino Ignite. The original was awesome, but we made it even better. The new label is blue instead of red. Still non-stimulant and naturally sweetened/flavored.

  • Bhathiya Rupasingha

    hello.2 years ago i used lipo 6 black and it make my heart pounding so much after finishing it then i used jym shred jym and arnold iron cuts but they dnt make me uncomfortable and no any heart pounding.now im going to get c4 ripped.is it safe?or is it dangerous like lipo 6?

  • Ted

    It looks like Shred Jym has 200mg of caffeine. Lipo 6 does not disclose caffeine but also has yohimbine which is another stimulant. C4 ripped looks like it has about 150-200 mg of caffeine but no other stimulants. My guess is that it was mainly the yohimbine that caused your reaction with Lipo 6.

  • Ray

    My bottle of cellucor c4 has 150mg of caffeine anhydrous.
