R5® is formulated for active adults in their 40s and 50s. This includes gym-goers, runners, cyclists, swimmers, tennis players, golfers, and anyone who exercises regularly and wants to maintain or improve their physical performance during midlife.

It is not designed for elite athletes, bodybuilders, or young fitness enthusiasts. The formula specifically addresses the physiological changes that occur in midlife — including declining muscle mass (sarcopenia), slower recovery, reduced cardiovascular efficiency, lower energy metabolism, and cognitive changes such as brain fog.

R5® is suitable for both men and women.

R5® contains seven active ingredients, each selected for its relevance to the health and performance needs of active adults in their 40s and 50s:

Creatine Monohydrate supports muscle strength, power output, brain function, and bone density. Creatine is one of the most researched supplements in history, with over 500 published studies confirming its safety and effectiveness. Research in adults aged 50 and over shows that creatine combined with resistance training significantly increases lean muscle mass, upper body strength, and lower body strength.

RedNite® Beetroot Extract is a concentrated, water-soluble beetroot powder standardised to contain 1.5%–2.75% natural nitrates. It supports nitric oxide production, which improves blood flow, oxygen delivery, and cardiovascular performance. Studies suggest beetroot nitrate supplementation can improve exercise endurance by 3–5% and support healthy blood pressure. RedNite® contains 5 times more nitrate and 10 times more antioxidants than standard beetroot powder. RedNite® is a trademark of Enovate Biolife, a part of OmniActive.

L-Carnitine L-Tartrate plays a key role in fat metabolism by transporting fatty acids into the mitochondria for energy production. It supports energy levels, body composition, and post-exercise recovery.

L-Arginine is an amino acid that serves as a precursor to nitric oxide, supporting blood flow, circulation, and reduced fatigue during exercise.

L-Taurine supports cardiovascular function, muscle endurance, electrolyte balance, and has antioxidant properties that help protect cells from oxidative stress.

L-Theanine promotes calm focus and mental clarity without drowsiness or stimulant effects. It helps address the mental fatigue and reduced sharpness many people experience in midlife.

Pomegranate Fruit Powder provides natural polyphenols and antioxidants that support the body's response to oxidative stress and aid recovery.

The full ingredient list, including flavouring and sweetener details, is available on the Ingredients page. Peer-reviewed research for each ingredient is available on the Studies page.

R5® is designed to be taken daily as a single drink. The ingredients work through several mechanisms:

Muscle and strength support: Creatine increases phosphocreatine stores in muscle, supporting ATP production during high-intensity exercise. This translates to improved strength, power, and work capacity.

Cardiovascular and endurance support: RedNite® Beetroot and L-Arginine both support nitric oxide production, which dilates blood vessels, improves blood flow, and enhances oxygen delivery to working muscles. This supports endurance, stamina, and cardiovascular health.

Energy metabolism: L-Carnitine facilitates the transport of fatty acids into mitochondria, supporting the body's ability to use fat as fuel and maintain consistent energy levels.

Mental clarity: L-Theanine promotes alpha brain wave activity, supporting focused calm without stimulants. Combined with the improved blood flow from beetroot and arginine, this helps address the cognitive decline many people notice in midlife.

Recovery and cellular protection: Pomegranate and L-Taurine provide antioxidant support, helping to reduce oxidative stress from exercise and daily activity.

The benefits of R5® build over time with consistent daily use. Most customers notice improvements in energy and training quality within 2–4 weeks, with optimal results typically observed after 60–90 days.

R5® vs multivitamins (Swisse, Blackmores, Centrum 50+): Multivitamins provide baseline vitamins and minerals to fill dietary gaps. R5® is a performance and recovery formula containing sport-science ingredients like Creatine, RedNite® Beetroot, and amino acids that multivitamins do not include. R5® does not replace a multivitamin — they serve different purposes and can be taken together.

R5® vs AG1 (Athletic Greens): AG1 is a broad-spectrum greens powder with 75+ ingredients, primarily focused on gut health, immunity, and general wellness. R5® contains 7 targeted ingredients chosen specifically for the performance and recovery needs of active adults in their 40s and 50s — including Creatine and RedNite® Beetroot, which AG1 does not contain. AG1 costs approximately $5.17 AUD per day compared to R5® at $3.30–$3.97 AUD per day.

R5® vs buying ingredients separately: Purchasing Creatine, beetroot extract, and individual amino acids separately would require 4–5 separate products, cost more per day, and create a more complex daily routine. R5® combines these in a single scoop with ingredients selected for their synergy.

REVIVE5 is an Australian-owned supplement company founded by Neill Johnston. The company makes one product — R5® — with a focus on simplicity, transparency, and science-backed formulation for active adults in midlife.

REVIVE5's approach is built on the idea that supplement routines should be simple enough to stick with daily. Rather than offering a range of products, the company focuses on delivering the key ingredients an active person in their 40s and 50s needs in a single daily drink.

R5® is formulated in Australia. The manufacturing process follows the HACCP Food Safety Program.

More about the company's story is available on the Our Story page.
