Science & Ingredients
Creatine Monohydrate 3000mg
Reason for inclusion:
Creatine supplementation improves high-intensity exercise performance by increasing the body’s ability to rapidly regenerate ATP, which supports strength, power and repeated high intensity efforts. It also supports cognitive performance and recovery and is classified as a Group A supplement within the AIS Supplement Framework. Supplementation guidelines recommend a daily dose of 3-5g with muscle saturation achieved in approximately four weeks with consistent consumption.
Mechanism and Cognitive Synergy:
Beyond its well-established physical benefits, creatine plays a critical role in cellular energy homeostasis throughout the central nervous system. Because the brain is an incredibly metabolically active organ, maintaining optimal phosphocreatine stores helps buffer cellular energy demands during periods of acute sleep deprivation, mental fatigue or intense cognitive load. This ensures a consistent supply of cellular fuel to support memory task execution, executive function and overall mental resilience.
L-Theanine 200mg
Reason for inclusion:
L-theanine promotes a calm, focused state by increasing brain wave activity, dopamine and glutamate, often reducing stress and anxiety. Evidence shows benefit for cognitive and mood outcomes when supplemented in a 100-200mg single-dose especially when paired with caffeine.
By specifically targeting and elevating alpha brain wave activity, L-theanine supports a state of "wakeful relaxation". This allows for the support of sustained attention, sharper focus and improved error-recognition during complex tasks, all while fostering a composed, level-headed mindset under pressure.
L-Tyrosine 400mg
Reason for inclusion:
L-tyrosine is a precursor of dopamine, noradrenaline and adrenaline, which are involved in mood, motivation, attention and stress response. L-tyrosine may support cognitive attention, working memory and reaction time.
Research suggests that L-tyrosine's benefits become most apparent when the body and mind are under cognitive or physiological load, which is exactly the conditions Altyr Rise is built for. It pairs directly with L-theanine in the formula, which promotes a calm, focused state without sedation, while L-tyrosine supplies the neurotransmitter precursors needed to maintain attention and decision-making as that demand continues. Where caffeine forces alertness through stimulation, L-tyrosine supports the brain's own capacity to sustain focus, which is why it sits at the center of Altyr Rise's stimulant-free approach to performance.
Sodium 304 mg (elemental)
Reason for inclusion:
Sodium is the principal electrolyte in extracellular fluid, helping regulate fluid balance and supporting nerve impulse transmission and muscle contraction. It also contributes to intestinal fluid absorption and fluid retention during rehydration. As the main electrolyte lost through sweat, sodium is particularly relevant for active individuals.
We selected Himalayan pink salt as a source of sodium for our formulation. Each serving of Altyr Rise provides 304 mg of elemental sodium to contribute to sodium replacement alongside adequate fluid intake.
Potassium 153 mg (elemental)
Reason for inclusion:
Potassium is the principal electrolyte inside cells, supporting intracellular fluid balance and the electrical gradients required for normal nerve signalling, muscle contraction and heart rhythm. Working alongside sodium through the sodium–potassium pump, it helps maintain normal cellular function.
We selected potassium citrate as a source of potassium suitable for our drink formulation. Each serving of Altyr Rise provides 153 mg of elemental potassium to complement dietary intake and support these essential physiological functions.
Magnesium 125 mg (elemental)
Reason for inclusion:
Magnesium is a cofactor in more than 300 enzyme systems, including those involved in energy production, protein synthesis and neuromuscular function. It supports glycolysis and oxidative phosphorylation pathways that generate cellular energy and helps regulate the ion transport required for normal nerve signaling and muscle contraction.
We selected magnesium citrate as a well-absorbed source of magnesium suitable for our drink formulation. Each serving of Altyr Rise provides 125 mg of elemental magnesium to complement dietary intake and support these essential physiological functions.
Vitamin B3 10mg
Reason for inclusion:
Vitamin B3 is essential for energy production, as it forms the coenzymes NAD+ and NADP+, which are required for hundreds of metabolic reactions that convert carbohydrates, fats and proteins intake usable cellular energy. It also supports cell signaling, nervous system and digestive system function.
Vitamin B6 3mg
Reason for inclusion:
Vitamin B6 is essential for amino acid metabolism, neurotransmitter synthesis (including serotonin and dopamine) and red blood cell formation. It also plays a key role in glycogen breakdown and immune system function, helping the body to convert food into useable energy.
Vitamin B9 400ug
Reason for inclusion:
Vitamin B9 is essential for DNA synthesis, cell division and red blood cell formation, making it critical for growth and tissue repair.
Vitamin B12 4ug
Reason for inclusion:
Vitamin B12 is required for the synthesis of fatty acids, and in conjunction with Vitamin B9, for DNA synthesis. Adequate intakes of vitamin B12 are essential for normal blood function and neurological function.
Red Beet Extract
Reason for inclusion:
Red beet extract provides colour through naturally occurring pigments called betalains. We selected it to give Altyr Rise its colour without artificial colouring agents.
Thaumatin
Reason for inclusion:
Thaumatin is a naturally occurring sweet-tasting protein extracted from fruit. Its high sweetness intensity means only a small quantity is needed. We selected it to provide sweetness and help balance the flavour of Altyr Rise without artificial sweeteners.

Olivia brings a level of scientific rigour to Altyr that is rarely seen in the supplement industry. Her practical experience matches her academic credentials. Working directly with elite Rugby Union and high-performance motorsport, Olivia has spent years translating clinical nutrition science into feasible, real-world protocols that produce measurable outcomes at the highest levels of professional sport. She understands not just what the research says, but what it means for a human body under genuine physical and cognitive demand.
When Sam and Shane approached Olivia to collaborate on Altyr Rise, her first question was simple. Show me the evidence. Every ingredient, every dose, every claim was put through the same rigorous scrutiny she applies to her doctoral research. What emerged from that process was a formula she was confident enough to put her name behind. Olivia played a central role in the design and development of Altyr's scientific framework, reviewing the clinical literature on each ingredient, validating the dosing rationale, and ensuring every element of the formula reflects the current standard of evidence in sports nutrition and general health science.
She continues to guide Altyr's scientific direction as the brand grows and its product range expands. In an industry built on proprietary blends and undisclosed doses, having a performance dietitian with elite sport experience on the founding team isn't a marketing exercise. It's the reason you can trust what's in every serve.
Backed by Science
Stimulant-based supplements target alertness. Altyr Rise takes a different approach: bringing together ingredients involved in cellular energy metabolism, neurotransmitter synthesis and electrolyte balance. Its focus is the physiology behind performance, not stimulation.
These systems are interconnected. Producing and using energy, maintaining fluid balance and regulating nerve and muscle activity all contribute to how we function physically and mentally. Altyr Rise brings these complementary roles into one daily formula, designed to support the body’s own energy processes alongside the foundations of good nutrition, hydration and recovery.
The formulation follows a simple principle: select ingredients not only for their individual roles, but for how those roles fit together. Energy metabolism provides the foundation, electrolytes support normal cellular and neuromuscular function, and L-theanine and L-tyrosine offer a complementary rationale for calmness and cognitive readiness.
Zero stimulants. A physiology-led formula built around the systems that support physical and cognitive performance.
