Coenzyme Q10 (CoQ10) – A crucially important nutrient (think: “catalyst” or “spark plug”) for the efficient production of energy from your food and oxygen intake. CoQ10 exists in every cell of the human body and facilitates proper functioning of all elements of energy production. Unfortunately, body stores naturally decline with age and are rapidly depleted during strenuous exercise, making supplementation essential.

CoQ10’s myriad of additional benefits include supporting the immune system, healthy blood pressure, aiding in the prevention of many forms of cancer, and playing a key role in the prevention of Parkinson's disease. It also helps promote healthy teeth and gums, and supports healthy skin by providing protection against UV radiation.

Idebenone – Supplies many of the same benefits as CoQ10, with some distinct advantages based on its more complex chemical structure. Perhaps the most remarkable feature of idebenone is its unique ability to operate under hypoxic (low oxygen) conditions, helping to produce energy and maintain high energy levels without creating free radicals, even at high altitude or during the most intense exercise sessions.

Vitamin E – A powerful antioxidant that, along with CoQ10 and idebenone, helps neutralize the free radicals naturally created during energy production. Vitamin E has numerous general health benefits as well, especially in regard to the cardiovascular and circulatory systems.

OxyAssist – A unique blend of nutrients which work in combination to enhance oxygen utilization, optimize fat burning, increase energy production, and buffer against acid build-up.

Trimethylglycine (TMG) – Helps convert fatty acids to energy. It has been used to treat muscular weakness and degeneration, due in part to its role in transporting oxygen to muscle tissues.

Inosine – Helps increase the oxygen-carrying capacity of the blood, allowing more oxygen to be delivered to working muscles, thereby reducing fatigue.

Krebs Cycle Intermediates – Supports the Krebs cycle (a.k.a. the citric acid cycle or the tricarboxylic acid cycle) by supplying precise amounts of the Krebs cycle intermediates malate, citrate, aspartate, lysinate and glycinate, which are chelators for the minerals calcium, magnesium, and potassium. Another Krebs cycle intermediate, alpha-ketoglutarate, is included as well.

Enzyme Blend (protease, amylase, glucoamylase, lipase, cellulase, phytase, maltase, and sucrase). Ensures proper digestion and absorption of this supplement.

Bioperine® – Black pepper fruit extract is used to support digestion and absorption. It has been shown to increase the absorption of important nutrients such as CoQ10 by over 30%.

Race Caps Reign Supreme

I recently bought Race Caps Supreme as a long time user of 1st Endurance Race Caps. In 2013, I ran 17 different endurance events, ranging from 5ks to Marathons; even qualifying and being accepted as a participant in Boston in 2014. Personally, I have found Race Caps Supreme to be a superior product ...

Still up for review...

I have been taking this for about 2 months now. I have not felt much of a difference at all. I am very active, so maybe my base metabolism and energy levels are too high to make an actual impact on performance.

Verified Reply - SteveThere are no animal/animal-derived ingredients in Race Caps Supreme. It is 100% acceptable for consumption by vegetarians/vegans.

Hi is this product recommend for children athletes (16 years old)?

Asked by Barn
Verified Reply - SteveTeenage athletes can certainly use Race Caps Supreme with no issues. That said, it's not as imperative a product as it is for older athletes, the reason being that younger athletes still have a sizable amount of Coenzyme Q10 in their body (CoQ10 is the main ingredient in Race Caps Supreme), and because younger athletes still have the ability to synthetize fair amounts of CoQ10 from the food they eat. Bodily levels of CoQ10 drop significantly with each passing decade, starting at age 30, and the ability to synthesize CoQ10 from food sources also decreases as we age. BOTTOM LINE: Your 16-year-old athlete may use Race Caps Supreme (1 capsule daily) without any issues at all; however, it is not a crucially needed product for a teenage athlete.

Hi you recommend taking Race Caps Supreme and the products in the PR kit together?

Asked by Barn
Verified Reply - SteveYou most certainly may include Race Caps Supreme with the products in the Race PR Kit. Keep in mind that Race Caps Supreme is a daily use supplement, while the products in the Race PR Kit are occasional use supplements. The reason why we recommend taking Race Caps Supreme on a daily basis--training days and non-training days--is because its nutrients, primarily Coenzyme Q10 and idebenone, are superb for many areas of general health, especially cardiovascular health. We discuss this in more detail at https://www.hammernutrition.com/knowledge/athlete-education-series/race-caps-supreme-aes-vol-3-14/

I take 200 mg of ubiquinol every day. How will taking race caps Supreme impact this. Can RCS help me not take the ubiquinol. Do I need both?

Asked by Ed
Verified Reply - SteveThe short answer to your question is that yes, you could still take some uibiquinol, if desired, but you could also fulfill most of your daily needs from Race Caps Supreme, half from its CoQ10 (Ubiquinone) content and half from its idebenone content. Here's why: Each capsule of Race Caps Supreme contains 30 mg of Coenzyme Q10 (CoQ10 -- Ubiquinone) and 30 mg of idebenone, a nearly identical nutrition to CoQ10. In the body, ubiquinone is converted to ubiquinol, which is considered to be the active form of CoQ10. Orally dosed ubiquinone needs to be broken down into ubiquinol, so when you buy a ubiquinol supplement you’re saving a metabolic step. One reason why we don’t use ubiquinol in Race Caps Supreme is because it is more expensive. And though there are some people who cannot convert ubiquinone into ubiquinol as efficiently as others, the overwhelming majority of people do not have that issue. However, to address that potential issue, and assist in absorption of CoQ10 (ubiquinone), we include various digestive aids. One is a Proprietary Enzyme Blend (protease, amylase, glucoamylase, lipase, cellulase, phytase, maltase, and sucrase), and the other is the well-researched standardized black pepper extract Bioperine™. The latter is of particular interest because it has been shown in reliable research to enhance the absorption rate of important nutrients such as CoQ10 by 30% (http://www.bioperine.com/index.php/coq10) The other reason why we prefer to use a dry powder CoQ10 is heat stability. A lot of people use Race Caps Supreme during their longer bouts of exercise, so a dry, more heat-stable form of CoQ10 is needed. Ubiquinol is supplied in liquid form or soft-gel form and is not quite as heat stable. Idebenone supplies many of the same benefits as CoQ10, with some distinct advantages based on its more complex chemical structure. Perhaps the most remarkable feature of idebenone is its unique ability to operate under hypoxic (low oxygen) conditions, helping to produce energy and maintain high energy levels without creating free radicals, even at high altitude or during the most intense exercise sessions. By taking 3 Race Caps Supreme daily, you will receive 90 mg of CoQ10 (ubiquinone) and 90 mg of idebenone, giving you a daily total of 180 mg of CoQ10 and "nearly identical to CoQ10" activity.

I have a long endurance event coming up (100 mile MTB race), which will probably last 9-10 hours. There are so many products that are said to help improve endurance (i.e., Race Caps Supreme, Anti-Fatigue Caps, Endurolytes, etc). If I had to choose one or two, what are the best products to take during an event of this nature?

Asked by Jeff
Verified Reply - SteveGreat question! First, Endurolytes supplies your body with electrolytes, so it's actually a part of your fuel, as important as the calories you're consuming to produce energy, and the fluids you're drinking to stay hydrated. So even though the product comes in capsule form, it's not really a supplement, but rather a fuel. That's why, out of all the products that come in capsules, Endurolytes ALWAYS comes first... you have to replenish electrolytes regularly during exercise! Race Caps Supreme is an extremely important product, not just because it enhances endurance, but mainly because its main components--Coenzyme Q10 and Idebenone--are so good for many aspects of overall health, especially cardiovascular health. Race Caps Supreme is a product that ALL people would benefit from EVERY SINGLE DAY, simply because of the wide-ranging benefits that it provides for multiple areas in human health. In terms of enhancing endurance, Race Caps Supreme often works right away for most people, though for others it may take a couple weeks of consistent use before noticeably tangible, endurance-enhancing benefits are seen. Anti-Fatigue Caps will work right out of the gate. As we exercise, ammonia is produced and accumulates, and the further we go, the more ammonia gets produced and the more of it accumulates in the blood and in the cells. Ammonia is a key culprit in fatigue, which, of course, robs endurance. By taking Anti-Fatigue Caps prior to exercise (2-4 capsules about 30 minutes prior) and hourly during (1-2 capsules), your body is supplied with nutrients that effectively scavenge this fatigue-causing ammonia. That will most definitely extend endurance. Out of all our Peak Performance supplements (https://www.hammernutrition.com/products/peak-performance/), Anti-Fatigue Caps gets my vote as the #1 product. One other product to consider is Fully Charged (https://www.hammernutrition.com/fully-charged/). Though promoted primarily as a pre-workout supplement, a lot of endurance athletes are experiencing MAJOR benefits by taking additional doses every 3-4 hours during extended bouts of exercise.

Can you take Race Caps Supreme if you also use Fully Charged before and during events?

Asked by KJ
Verified Reply - Hammer SteveYou can absolutely use Race Caps Supreme in tandem with Fully Charged. Race Caps Supreme contains CoQ10 and idebenone (and other nutrients), which are key substrates/catalysts ("spark plugs") for energy production. Race Caps Supreme is also a tremendous source of antioxidants. Take this product 15-45 minutes before exercise to give your body a head start on energy production capabilities and free radical neutralization. Take Race Caps Supreme every 60-90 minutes during exercise as well; think of this as "replacing the spark plugs" in your body, helping ensure more consistent energy production during prolonged exercise. Fully Charged contains a number of nutrients to address several areas in exercise performance... • Boosting nitric oxide levels • Increasing mental alertness • Enhancing fat utilization • Buffering acidity • Stimulating the production of ATP • Alleviating muscular soreness Take a dose of Fully Charged 5-30 minutes prior to exercise. Its beneficial effects have been tested and found to last at least 3 hours, oftentimes 4 hours. Still, many athletes have taken doses every 2 hours and reported outstanding benefits. Because there is such a minimal amount of caffeine in a serving (about 15 mg), and with no stimulants in the product, it can be taken every couple of hours if desired.

Can you take Race caps on workout days only?

Asked by Jun
Verified Reply - Hammer SteveYes, you can certainly take Race Caps Supreme only on workout days. However, you will not be receiving the full benefits that the product has to offer in terms of overall health, especially cardiovascular health. The main nutrients in Race Caps Supreme are so beneficial for the heart and many other organs, that even 1 capsule daily on non-workout days will be highly beneficial. Race Caps Supreme is headed up by Coenzyme Q10 (CoQ10), and you can read about its many benefits for general health at https://www.hammernutrition.com/blog/more-pep-in-your-step/

Hi, what is the difference between the PR kit and the Race Caps Supreme?

Asked by Ryan
Verified Reply - Hammer SteveRace Caps Supreme is a daily-use supplement. For athletic performance Race Caps Supreme contains a number of nutrients that act as catalysts (think "spark plugs") that help the body produce energy more efficiently from the calories you consume and the oxygen you breathe in. Any time you can positively influence energy production, you will enjoy greater endurance. Many of these same nutrients also have superb antioxidant properties, so Race Caps Supreme is excellent for enhancing recovery. The Coenzyme Q10 and idebenone components in Race Caps Supreme are extremely beneficial for cardiovascular health. The Race PR Kit contains three products: Anti-Fatigue Caps, Energy Surge, and Race Day Boost. These three products are not necessarily daily-use supplements. Anti-Fatigue Caps are to be taken prior to and hour during workouts and events, ideally the longer-duration workouts lasting 2+ hours, to help extend endurance by neutralizing the fatigue-causing effects of excess ammonia. Energy Surge is a "take it when you need it" supplement, meaning that you can use it anytime you need an extra boost of energy during a workout of race. During longer-duration workouts, the body's ability to make its own energy (ATP) may become greatly diminished. Taking Energy Surge during this time acts as a "primer" for the body's ATP "pump" to help it reestablish its own ATP-producing capabilities. Race Day Boost is a product that, once you've tested it in your training, you should reserve for your key events; it's not a daily-use or even occasional-use product. Instead, you take Race Day Boost in a loading dose protocol in the four days prior to an event. Race Day Boost enhances the performance of all three of the body's energy producing systems: The short-term ATP/CP system, the medium-term lactic acid energy system, and the long-term oxygen/aerobic energy system.

Do Race Caps Supreme contain caffeine? If so, how much?
