Dear Performance Nutrition Leaders,
This week: Nitrate + BFR, the latest news, and an important supplement partnership model.
💡 LATEST RESEARCH
Beetroot juice has a well-established evidence base in endurance sport. Its application in strength and power contexts is less settled.
A new randomised, double-blind, placebo-controlled study tested whether beetroot juice supplementation could amplify the adaptive response to blood flow restriction training.
Twenty male university students were assigned to either a BFR training group or a BFR plus beetroot juice group, with the supplemented group receiving 8 mmol of dietary nitrate per day throughout a one-week pre-loading phase and a four-week bilateral knee extensor and flexor BFR programme.
Both groups improved from baseline. Under fatigued conditions, the BFR plus beetroot juice group showed significantly greater improvements in bilateral CMJ height (p = 0.012, d = 1.307), peak force, and rate of force development compared to BFR alone.
Dietary nitrate is reduced to nitrite via the enterosalivary cycle and subsequently to nitric oxide through the nitrate-nitrite-NO pathway, improving muscle blood flow and reducing the oxygen cost of contractions.
The sample was small and drawn from a university sports cohort rather than elite athletes. Habitual dietary nitrate intake from food was not controlled for.
For practitioners using BFR in rehabilitation or load-managed training blocks, nitrate supplementation should be considered as a concurrent nutrition strategy.

Most supplement partnerships in elite sport work the same way. Brand pays a fee. Club wears the logo. Athletes post on social.
The IM8 and Inter Miami deal is structured differently.
IM8 is a daily performance supplement brand co-founded by David Beckham and owned by Prenetics. Inter Miami is the MLS club Beckham co-owns.
Under the multi-year agreement, IM8 becomes the club's exclusive Official Health Supplements Partner — and according to the club, Inter Miami has taken an equity stake in Prenetics, the first time it has taken an ownership position in a brand partner.
And important for us, it shows the value of sports nutrition.
The flagship product, Daily Ultimate Essentials, is an all-in-one powder containing 92 ingredients, engineered to replace 16 separate supplements in a single daily serving.
The product is NSF Certified for Sport.
Prenetics has confirmed it will be made available to all Inter Miami players and staff at the Florida Blue Training Center, with a dedicated IM8 Nutrition Center being built inside the facility.
Practitioners are often under-resourced. A well-structured brand partnership can be one of the few realistic routes to upgrading the environment they work in.
