If you found a performance supplement that enhanced the functions and performance of your body’s three energy production pathways, and also effectively buffered lactic acid, you’d take it, wouldn’t you? Hammer Nutrition’s Race Day Boost is that product – and yes, it’s safe and legal! In the most extensive study to date on Race Day Boost’s primary ingredient, fit cyclists in a 40K time trial netted a whopping 8% improvement in performance time. The simple formula belies its profound effectiveness, aiding in increased cellular energy production and buffering performance-robbing lactic acid.

No matter what duration your event may be, a four-day loading dose of Race Day Boost prior to a key race can make a noticeable difference in your performance. This is a special product for special events, but if you intend to meet or exceed your race day expectations, you better have Race Day Boost in your arsenal.

Note – The MAXIMUM recommended time you can use this product is 4 TIMES per year.

Usage Info

Race Day Boost Capsules:

Take 4 capsules of Race Day Boost with food or juice 4 times per day (total of 16 capsules daily) for 4 days prior to competition.

If doing a multi-day event this protocol may be used:

  • Follow the same 4-day loading protocol as described above.
  • Take 4 capsules of Race Day Boost with Recoverite as soon as possible after the race, with another 4-capsule dose of Race Day Boost with food later in the day/evening.
  • Follow this twice daily “maintenance dose” protocol after each stage.

**This product must be tested in training prior to use for a race.


The majority of the studies of the main ingredient in Race Day Boost (RDB), sodium tribasic phosphate, showed remarkably positive, performance-enhancing results with administration of 1 gram (1000 mg) of the nutrient four times daily for four straight days. That is our dosage recommendation for most athletes. However, it is theoretically possible that lighter weight athletes may be able to achieve the same benefits using less of this nutrient.

With that in mind, here are some suggested usage instructions—based on a range of body weights—which you may want to test in your training:

Alternate Race Day Boost Loading Dose Protocol

Up to 57 kg
Day One: 4 capsules one time/day
Day Two: 4 capsules two times/day
Day Three: 4 capsules two times/day
Day Four: 4 capsules three times/day

58 – 72 kg
Day One: 4 capsules two times/day
Day Two: 4 capsules three times/day
Day Three: 4 capsules three times/day
Day Four: 4 capsules four times/day

73 + kg
Day One: 4 capsules four times/day
Day Two: 4 capsules four times/day
Day Three: 4 capsules four times/day
Day Four: 4 capsules four times/day

*It’s important to note that these are estimated doses. Each athlete must test this protocol for Race Day Boost in training before using it in the four days prior to a race.
