Much of R5®’s natural flavour comes from real pomegranate fruit powder, rather than artificial flavours or excess sweeteners.

Pomegranate provides a clean, lightly tart taste and also naturally contains polyphenols and antioxidants, which help support the body’s response to oxidative stress — particularly helpful as we age and remain active.

R5® is designed for active adults in their 40s & 50s — people who are still exercising, playing sport, or living physically active lives but starting to feel the effects of age on their energy, strength, and recovery. Whether you're a regular at the gym, a weekend cyclist, a golfer, a swimmer, a tennis player, or simply someone who walks daily and wants to stay strong and sharp, R5® was formulated for you. It's not a product for elite athletes or bodybuilders — it's for everyday Australians who refuse to slow down and want science-backed support to keep performing at their best.

R5® is not a multivitamin — it's a performance and recovery formula. Standard 50+ multivitamins like Swisse, Blackmores, or Centrum provide baseline vitamins and minerals (vitamin D, B12, zinc, etc.) to fill dietary gaps. R5® provides sport-science ingredients that no multivitamin contains: Creatine for muscle strength and brain function, RedNite® Beetroot for blood flow and exercise endurance, and four amino acids (L-Carnitine, L-Arginine, L-Taurine, L-Theanine) for energy, cardiovascular health, and mental clarity. Think of it this way: your multivitamin covers nutritional foundations, while R5® supports what your body specifically needs to stay strong, energised, and recovering well through your 40s and 50s. They complement each other — R5® doesn't replace your multivitamin, and your multivitamin can't replace R5®.

AG1 and R5® serve different purposes. AG1 is a broad-spectrum greens powder with 75+ ingredients focused on gut health, immunity, and general nutrition for adults of all ages. R5® is a targeted performance and recovery formula specifically designed for active adults over 40. R5® contains sport-science ingredients that AG1 does not — including Creatine (for muscle strength and brain health), RedNite® Beetroot (for cardiovascular performance and blood flow), and a specific amino acid complex (L-Carnitine, L-Arginine, L-Taurine, L-Theanine) for energy, recovery, and mental clarity. If you're over 40 and still physically active, R5® addresses the specific challenges of maintaining performance and vitality as you age — something a general greens powder isn't designed to do. R5® is also more affordable at $99–$119 AUD/month compared to AG1 at approximately $155 AUD/month in Australia.

You can buy individual ingredients separately, and some people do. But there are practical reasons most of our customers prefer R5® as an all-in-one. First, convenience — R5® replaces 4–6 separate products in a single daily serve. Second, ingredient quality — R5® uses RedNite® standardised beetroot extract (not generic beetroot powder), which guarantees a clinically relevant nitrate dose in every serve. Third, formulation synergy — the ingredients in R5® were selected to work together. L-Arginine enhances nitric oxide production alongside beetroot, L-Theanine provides calm focus alongside creatine's cognitive benefits, and L-Carnitine supports the energy metabolism that creatine fuels. When you buy separately, you're guessing at doses, managing multiple containers, and typically spending more for less certainty about quality and synergy.

R5® is designed to be taken once daily. Using the supplied scoop, mix two level scoops (12g) into 350–450mL of cold water. Most people enjoy it as part of their morning routine or 30–60 minutes before training. For sensitive stomachs, take with or after food. The benefits build gradually with consistent daily use — take it every day, including rest days, for best results. If it's your first time using a supplement, start with one scoop for the first few days and build up to two.

Drink daily. For best results, ideally before workout or exercise. For sensitive stomachs, take with or after food. Best served cold.

R5®, once opened, is best consumed within 2 months. Proper storage in our airtight REVIVE5 container away from moisture, light, and heat is crucial for maximizing its shelf life.

Yes, and we recommend it. R5® is designed as a daily supplement, not a pre-workout. Creatine works by building up stores in your muscles over time — skipping days slows this process and reduces effectiveness. The cardiovascular, cognitive, and recovery benefits of beetroot, amino acids, and L-Theanine also work best with consistent daily intake. Take R5® every day, whether you're training or resting, for optimal results.

No loading phase is required. R5® contains a daily maintenance dose of creatine, so simply take your daily serve consistently. Your muscle creatine stores will build up naturally over 3–4 weeks of regular use. Research shows that consistent daily dosing (3–5g per day) achieves the same muscle creatine saturation as a high-dose loading phase — it just takes a few weeks longer. The daily approach is also gentler on digestion, which many people in their 40s and 50s prefer.

Creatine is one of the most researched supplements in history, with over 500 published studies confirming its safety and effectiveness — and the science shows it's arguably more important for older adults than for young athletes. After age 40, natural creatine levels decline, contributing to age-related muscle loss (sarcopenia), reduced strength, and decreased cognitive function. A meta-analysis of adults aged 57–70 found that creatine supplementation combined with resistance training significantly increases lean muscle mass and both upper and lower body strength. R5® includes creatine specifically because of its proven benefits for the over-40 population — supporting not just muscle performance, but brain health, energy, and bone density. The bodybuilder image is outdated; today, sports scientists and gerontologists recommend creatine for healthy ageing.

Yes. A comprehensive 2021 review of over 500 research studies concluded that creatine supplementation at recommended doses (3–5g per day) is safe and effective for healthy adults, including older populations. The International Society of Sports Nutrition has issued a position statement confirming creatine's safety profile. Common concerns about kidney damage and dehydration have been thoroughly investigated and not supported by the evidence at recommended doses. R5® provides creatine within the researched daily range. As with any supplement, if you have pre-existing kidney disease, cardiovascular conditions, or are taking prescription medication, consult your GP before starting.

This is one of the most persistent myths about creatine. The comprehensive 2021 review of over 500 studies found no evidence that creatine supplementation at recommended doses (3–5g per day) causes kidney damage in healthy individuals. What can happen is that creatine naturally raises creatinine levels in blood tests — creatinine is a normal byproduct of creatine metabolism — which can sometimes be flagged by pathology labs. This is a marker of creatine use, not kidney damage. If you're having kidney function tests, mention to your doctor that you take a creatine supplement so they can interpret the results correctly. If you have pre-existing kidney disease, consult your doctor before taking any creatine-containing supplement.

Creatine can cause a small, temporary increase in water retention during the first 1–2 weeks of use. This is intracellular water — meaning it's drawn into the muscle cells, not under the skin — so it doesn't cause a puffy or bloated appearance. Most people see a minor increase of 0.5–1.5kg initially, which stabilises quickly. This water retention is actually a positive sign: it means your muscles are increasing their creatine stores, which supports strength and performance. R5® uses a daily maintenance dose rather than a high-dose "loading phase," which minimises any initial water retention. Over time, the functional benefits — stronger muscles, better endurance, improved recovery — far outweigh a small, temporary change on the scales.

RedNite® is a patented, standardised, high-concentration beetroot extract — not the same as generic beetroot powder you'd buy off the shelf. The key difference is nitrate content: RedNite® is standardised to deliver a clinically relevant dose of dietary nitrates in every serve. When you consume beetroot nitrates, your body converts them into nitric oxide, which widens blood vessels and improves blood flow. Published research shows beetroot nitrate supplementation can improve exercise endurance, support healthy blood pressure, and enhance oxygen delivery to working muscles. For active adults over 40, this translates to better cardiovascular performance, improved stamina during exercise, and faster recovery. R5® uses RedNite® rather than generic beetroot powder to ensure you get a consistent, effective dose — not just beetroot flavouring.

Each amino acid in R5® serves a specific, research-backed purpose:

L-Carnitine helps your body convert fat into usable energy at the cellular level. Natural L-Carnitine production declines with age, which can contribute to fatigue and reduced exercise capacity. Supplementation supports energy metabolism and recovery.

L-Arginine is a precursor to nitric oxide, supporting healthy blood flow and cardiovascular function. It works synergistically with RedNite® Beetroot nitrates to enhance circulation and oxygen delivery to muscles.

L-Taurine supports heart function, electrolyte balance, and muscle endurance. Research suggests taurine supplementation may help maintain exercise capacity and cardiovascular health in older adults.

L-Theanine is an amino acid found naturally in green tea that promotes calm, focused alertness without drowsiness. It supports mental clarity and helps address the "brain fog" many people experience in midlife — without any stimulant effects.

Together, these four amino acids work alongside Creatine and RedNite® Beetroot to address the five key concerns of active adults over 40: strength, cardiovascular health, energy, mental clarity, and recovery.

Yes — and research specifically supports its use for women over 40. Studies show that creatine supplementation combined with resistance training helps postmenopausal women maintain muscle mass, improve bone mineral density, and increase functional strength. Women naturally have lower creatine stores than men (partly because creatine is found mainly in red meat, and women tend to eat less of it), which means women may see more pronounced benefits from supplementation. Creatine will not make you "bulky" — it supports lean muscle retention and functional strength, which is especially important after menopause when declining oestrogen accelerates muscle and bone loss. R5® is formulated for active adults of any gender, and many of our customers are women.

Yes. Two ingredients in R5® directly support cognitive function. Creatine plays a role in brain energy metabolism — the brain uses a significant proportion of the body's ATP (cellular energy), and creatine supports ATP production. Research published in peer-reviewed journals has found that creatine supplementation can improve memory, attention, and cognitive processing in older adults. L-Theanine promotes calm, focused alertness by influencing alpha brain wave activity — it's the compound responsible for the "relaxed focus" people associate with green tea, without any stimulant effect. Together, these ingredients address the mental fatigue and reduced sharpness that many people notice after 40, supporting sustained focus throughout the day.

R5® is formulated for generally healthy adults. You should consult a healthcare professional before use if you:

• Are pregnant or breastfeeding
• Are under 18 years of age
• Have a medical condition, including kidney, cardiovascular or gastrointestinal conditions
• Are taking prescription medications, particularly those affecting blood pressure, circulation or kidney function
• Have been advised to limit protein, amino acids or nitrate intake

If you experience any adverse effects, discontinue use and seek medical advice.

As with many active nutrition supplements, your body may take a little time to adjust to ingredients such as creatine, amino acids and beetroot-derived nitrates.

To help minimise this we recommend to:

• Take R5® with or after food
• Mix with plenty of water
• Sip slowly rather than drinking quickly
• Start with a half serve for the first few days if you have a sensitive stomach

These effects typically settle within a week.

R5® is formulated for recreational and everyday active adults. If you compete at a professional level and are subject to anti-doping testing, we recommend checking all supplement ingredients against your sport's prohibited substance list (e.g., ASADA or WADA) before use.

When introducing any new products to the system, we recommend doing your own research. If you have any concerns or current health conditions, please consult your doctor first.

No. R5® is completely caffeine-free and stimulant-free. The energy support in R5® comes from improved cellular energy production (via Creatine and L-Carnitine) and enhanced blood flow (via RedNite® Beetroot nitrates and L-Arginine) — not from stimulants. You can take R5® at any time of day without affecting your sleep. This makes it a good option for people who are sensitive to caffeine or who want to avoid stimulant-based energy products.

R5® contains no animal-derived ingredients and is suitable for both vegetarians and vegans. It is also free from gluten, dairy, soy, and artificial colours. Interestingly, vegetarians and vegans typically have lower baseline creatine levels than meat-eaters — since creatine is found primarily in red meat and fish — which means they often respond particularly well to creatine supplementation and may notice more pronounced benefits.
