Frequently Asked Questions

4VIA™ is a doctor-formulated structured systems nutrition brand built around a Morning + Night daily ritual.

The ritual combines Intelligent Systems Nutrition™, the comprehensive morning drink formula, with Rest Phase™, the melatonin-free evening formula. Together, they are designed around day-to-night biology, long-term consistency and clinically informed daily-use dosing.

4VIA is pronounced “for via” and means “for life.” The name reflects the brand purpose: a structured daily nutrition ritual designed for consistency and long-term use.

Structured systems nutrition is the 4VIA approach to everyday nutrition: organising foundational nutrients, digestive ingredients, plant compounds, botanical ingredients, functional mushrooms and selected bioactives into a coherent daily architecture, rather than presenting them as an unstructured ingredient list.

For 4VIA, that structure includes a comprehensive morning formula, a complementary evening phase and a framework built around 12 interconnected systems of health.

Intelligent Systems Nutrition™ includes selected greens, fruits and plant ingredients, but 4VIA is not positioned as a conventional greens powder.

It is better understood as a Morning + Night structured nutrition ritual: a comprehensive morning formula combined with a complementary melatonin-free evening phase. The difference is not simply ingredient count. It is the architecture.

Intelligent Systems Nutrition™, or ISN, is the comprehensive 4VIA morning drink formula. It contains 111 ingredients structured through BioArchitectureMatrix™, including vitamins, minerals, fruits, greens, fibres, live bacterial cultures, digestive enzymes, functional mushrooms, botanicals, amino acids, polyphenols and selected cellular bioactives.

Rest Phase™ is the 12-ingredient 4VIA evening formula. It is designed as the complementary night phase of the daily ritual and is melatonin-free.

The complete ritual combines Intelligent Systems Nutrition™ in the morning with Rest Phase™ in the evening. Together, they contain 123 components and are designed around a structured daily routine, phase-based nutrition and long-term consistency.

Morning and evening are different parts of the daily routine. Intelligent Systems Nutrition™ provides the comprehensive morning foundation, while Rest Phase™ provides a distinct evening phase.

This allows 4VIA to be structured as a daily ritual rather than forcing every component into one formula or one moment of the day.

Intelligent Systems Nutrition™ can be used as the comprehensive morning formula on its own. However, the complete 4VIA system is designed as a Morning + Night Ritual. Using ISN in the morning and Rest Phase™ in the evening provides the full structured daily ritual as intended.

BioArchitectureMatrix™ is the formulation architecture behind Intelligent Systems Nutrition™. It organises the morning formula into connected nutritional layers: foundational vitamins and minerals, digestive and microbiome ingredients, structural compounds, botanicals, functional mushrooms, polyphenols and selected cellular bioactives.

BioArchitectureMatrix™ refers to ISN specifically; Rest Phase™ is the separate evening phase of the wider ritual.

4VIA is built around 12 interconnected systems of health:

• Energy
• Immunity
• Cognition & Nerves
• Heart Health
• Hormonal Balance
• Gut & Digestion
• Liver Health
• Thyroid Function
• Muscle Support
• Bones & Cartilage
• Skin, Hair & Nails
• Cell Protection

These areas are anchored through relevant included vitamins and minerals using authorised health claim language.

Gut-centred architecture means that Intelligent Systems Nutrition™ treats digestion and the microbiome layer as an important part of the wider formula foundation. ISN includes fibres, live bacterial cultures, digestive enzymes and plant ingredients alongside its broader nutrient, botanical and bioactive architecture.

Intelligent Systems Nutrition™ contains 111 ingredients organised through BioArchitectureMatrix™. Its ingredient groups include vitamins and bioavailable mineral forms; fruits, greens and anthocyanin-rich plant ingredients; fibre, live bacterial cultures and digestive enzymes; functional mushrooms; botanical extracts; amino acids and structural compounds; polyphenols; and selected cellular bioactives.

Key formula features include Vitamin D3 with K2, dual-form Vitamin B12, magnesium bisglycinate, live bacterial cultures, digestive enzymes, functional mushrooms, maca, fenugreek, shilajit, CoQ10, nicotinamide riboside chloride, astaxanthin and spermidine-rich wheat germ extract.

No, and that is intentional.

A “clinical dose” is not one universal benchmark. It refers to the amount used in a particular study, for a particular population, outcome and period of time. Many clinical trials examine a single ingredient at a higher dose over a relatively short intervention.

4VIA is formulated differently. Intelligent Systems Nutrition™ is a comprehensive daily nutrition formula designed for consistent, long-term use across multiple interconnected systems of health. Selected pillar ingredients are included at clinically aligned or research-led amounts where appropriate. Other ingredients are used as supporting components within broader nutritional layers, with their doses determined by their role in the complete formula.

The objective is not to reproduce the highest standalone trial dose of every ingredient in one scoop. Doing so would create an unnecessarily large and potentially poorly tolerated formula. Instead, 4VIA uses clinically informed, long-term appropriate, multi-system daily-use dosing, balancing evidence, ingredient interactions, total daily exposure, tolerability, taste and consistency.

This means 4VIA should not be interpreted as 111 separate high-dose supplements compressed into one serving. It is one structured formula in which different ingredients have different roles and dosing priorities.

Ingredients within Intelligent Systems Nutrition™ are used at different dosing levels according to their function within the BioArchitectureMatrix™:

Essential nutrient foundation
Vitamins, minerals and trace elements are supplied in clearly declared amounts, with reference intake values shown where established.

Clinically aligned pillar ingredients
Selected ingredients are included at amounts informed by published human research and established daily-use ranges. Examples include 1,000 mg MSM, 30 mg saffron extract, 120 mg sodium hyaluronate, 4 mg astaxanthin and 10 billion CFU of live cultures.

Research-led functional ingredients
Ingredients such as nicotinamide riboside, CoQ10, black seed extract, spermidine and maca are included at meaningful daily-use amounts selected for their role within the wider formulation.

Supporting architecture
Botanicals, fruits, greens, mushrooms, fibres, amino acids and digestive ingredients complete specific formulation layers. These are not presented as standalone clinical protocols. They work as supporting parts of the complete nutritional architecture.

Every ingredient is not expected to perform the same function or require the same dose. The formula is built around hierarchy, interaction and long-term daily use, not ingredient count alone.

Ingredient count alone cannot determine whether a formula is appropriately dosed.

Intelligent Systems Nutrition™ contains a 15 g serving, but its ingredients do not all have the same purpose or dosing requirement. Vitamins and trace minerals may be effective at microgram or milligram amounts, live cultures are measured in CFU, enzymes are measured by activity, standardised botanical extracts may be more concentrated than whole-plant powders, and major structural ingredients require larger amounts.

4VIA therefore does not divide 15 g equally between 111 ingredients. The formula uses a dosing hierarchy. Foundational nutrients and selected pillar ingredients receive defined, meaningful amounts, while other ingredients support broader formulation layers.

4VIA is not designed to reproduce 111 separate standalone supplement protocols. It is designed as one comprehensive, clinically informed daily nutrition formula.

Intelligent Systems Nutrition™ includes selected nutrient forms such as riboflavin-5′-phosphate, pyridoxal-5′-phosphate, calcium-L-methylfolate, Vitamin K2 as menaquinone-7, magnesium bisglycinate and selenomethionine.

ISN uses two forms of Vitamin B12 — methylcobalamin and hydroxocobalamin — within its wider nutrient architecture. It provides 65 mg magnesium in the morning formula, while the complete Morning + Night Ritual provides 150 mg magnesium per day across both phases.

4VIA is built around Energy, Immunity, Cognition & Nerves, Heart Health, Hormonal Balance, Gut & Digestion, Liver Health, Thyroid Function, Muscle Support, Bones & Cartilage, Skin, Hair & Nails and Cell Protection.

These areas are anchored through included vitamins and minerals with recognised nutrient contribution language. For the full ingredient-to-benefit breakdown, visit the Benefits page.

ISN contains vitamins and minerals that contribute to normal energy-yielding metabolism and reduction of tiredness and fatigue, including B vitamins, Vitamin C and Magnesium. It contains Vitamins A, C, D, B6, B12, Folate, Zinc and Selenium, which contribute to normal immune function.

It also contains nutrients contributing to normal mental performance, cognitive function, psychological function and normal functioning of the nervous system, including Pantothenic Acid, Zinc, Iodine, B vitamins, Vitamin C and Magnesium.

The wider architecture is anchored through included nutrients: Vitamin B1 and Potassium for heart-health claim anchors; Vitamin B6 for hormonal activity; Calcium for digestive enzyme function; Choline for liver function; Iodine and Selenium for thyroid function; Vitamin D, Magnesium and Potassium for muscle function; Vitamins D and K, Calcium, Magnesium and Vitamin C for bone and cartilage claim anchors; Zinc, Selenium, Biotin and Vitamin C for skin, hair and nail claim anchors; and vitamins and minerals including Vitamins C, E, B2, Zinc, Selenium, Copper and Manganese for protection of cells from oxidative stress.

4VIA is designed around consistency rather than overnight transformation. Individual experience can vary depending on diet, lifestyle, routine and nutritional status. Some people may notice that the ritual fits naturally into their day quickly, while the wider value of structured daily nutrition is best understood through continued, consistent use over time.

Intelligent Systems Nutrition™ has an açaí, blueberry and pineapple flavour profile with subtle cocoa and vanilla undertones. It is designed to taste berry-forward and natural.

Its naturally deep berry-burgundy appearance comes from colourful plant ingredients within the formula, including purple sweet potato, black carrot, blueberry, açaí and beetroot. It is not a conventional green drink.

One daily serving of Intelligent Systems Nutrition™, or one 15 g scoop, contains 17 kcal.
