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.

    I would love to know the caffeine content in “Craze” by Driven Sports. It is fastly becoming everyone’s #1 preworkout supplement but of course, it’s a propietary blend. Thanks

  • ted

    Hi Scott, I listed it above. Caffeine in Craze is listed last in their proprietary ingredients and others that reviewed it estimated it at around 80mg. Thanks for the suggestion.

  • James M

    How much in Musclepharm Assault?

  • ted

    Hi James, Sorry Muscle Pharm doesn’t disclose or even estimate. 🙁

  • Kurt

    can someone please tell me how much caffiene is in superpumpmax per scoop please? thank you

  • ted

    Sorry Kurt, They won’t disclose it. Perhaps if you email them and threaten a lawsuit, then they might tell you.. I don’t know why these guys can’t at least disclose caffeine content.

  • Scott H

    I notice you have a couple BSN products listed above. Will they disclose the caffeine content in their N.O.Xplode 2.0 product? Thanks

  • ted

    For some reason BSN discloses for some of their products and for others do not. N.O. Xplode is a do not, sorry.

  • John

    I’m holding a container of N.O. Xplode in my hand right now. It states that one scoop contains approximately 200 mg of caffeine.

  • ted

    Thanks John, I can’t find that number posted anywhere online. BSN doesn’t list it on their site.

  • JJ

    how much caffeine in MRI Black Powder?

  • ted

    Not exactly sure since the don’t disclose, but the label says Caffeine, Green Tea Extract, Betaine Anhydrous are 202mg. So I would say the pure caffeine content is around 150mg+ per packet.

  • David Buddingh

    Caffeine in Synergenics Workout Mode is .025 mg. 1/199 of a 5 oz cup of decaf coffee.

    Can it be added to the list?

  • Brett

    I have been using BPI’s 1MR, and fell in love with how ‘motivated’ the product makes me. However, after the third bottle, I have developed serious headaches if I don’t take it one day (I work out every day). Obviously, it turns out to be caffiene headaches.. crap. Hence, why I searched this, and now I am amazed at what I discovered, and will stop using the product. Thanks for the info.
