Product Detail & Benefits


If you're not taking Race Caps Supreme, you simply are not getting the most out of your training! Several important substrates ("spark plugs"), such as Coenzyme Q10 (CoQ10) and idebenone, are crucial for the efficient production of energy from your food and oxygen intake. Exercise rapidly depletes these important nutrients. Taking Race Caps Supreme is like putting fresh spark plugs in your body, ensuring consistent, efficient energy production. In addition, CoQ10 and idebenone, as well as other ingredients in Race Caps Supreme, are superb antioxidants and key nutrients for cardiovascular health (idebenone is considered by many experts to be an important anti-aging nutrient, perhaps the most important one yet discovered). Other suppliers offer anemic attempts at an endurance supplement, but Race Caps Supreme stands alone as a safe, comprehensive, and effective formula promoting higher energy levels, increased endurance, and improved recovery. If there's one supplement to buy, this is it.


Note: The endurance enhancing benefits, general health benefits, and potential anti-aging benefits derived from Race Caps Supreme are cumulative. We recommend taking this product on a daily basis. For even greater and more amplified benefits take Race Caps Supreme with Mito Caps.

Rated 5 out of 5 by from Long time user I have used these for ultrarunning including 100 milers for 12 years and wouldn't start a race without them. I starting taking them daily 2 years ago and believe how quickly I recover from the many activities I subject my 64 year old body to.

Rated 4 out of 5 by from Old Guys Rule I have been using Race Caps Supreme for several years now and definitely have seen and felt the performance benefits. As a member of the over 50 crowd, Race Caps improve my performance on the longer, more technical outings... I take 3 race caps, 2 Anti-Fatigue and my Heed and I have fun riding against riders half my age !!

Rated 5 out of 5 by from Outstanding results I used the product as advertised and got great results. One a day on non workout days and I would use 2 an hour prior to workouts. After no activity for over 3 years I lost over 70 lbs and started training for a 5K Turkey Trot. My goal was to finish it nonstop in under 30 minutes. I took 3 an hour before the race and finished in 28:18. I didnt break any records but exceeded expectations and couldn't be happier.

Rated 5 out of 5 by from Race Caps Make a Noticible Difference I take these daily as advised and a few extra on big workout or race days. I notice and have the wattage PR's to prove that these make a difference. I really like them on days where I have long intervals where the legs usually fall off - but they don't when I keep these as part of my daily routine.

Rated 5 out of 5 by from Works everytime! I'm a 56 year old guy that still loves to grind it out riding my fatbike on the trails and roads here in Colorado. My pre-ride routine includes 2 to 3 RCS caps along with Hammer's AntiFatigue Caps and Endurance Aminos. They always seem to make me feel a little stronger, especially on the hills, and as a result I have more confidence in my ability to push through and ride like a kid again.

Rated 5 out of 5 by from A no brainer I began using Race Caps Supreme two years ago. I wish I would have known about them sooner. I use many Hammer products at different phases of my training and racing. Race Caps Supreme are part of all phases of my cycle. It is so effective at enhancing my energy/endurance during training/racing and aids in recovery. My muscles have never felt so great after long event. Race Caps Supreme are always on my list of race day supplies.
Date published: 2014-04-01
Rated 5 out of 5 by from I just started using Race Caps Supreme a few weeks ago while training for a big year of hilly trail races. My body during hard training runs of all types has been able to sustain a new, higher threshold and feels amazing the days after. At first, I kept waiting for the 2 day lag of soreness, but it never came. I directly contribute these to the added benefits from the RCS tablets. Excited to see if my performance continues to improve during my upcoming races when I combine these with the Race Day Boost tablets.
