What is in Aura

Aura contains 15,000mg of hydrolysed marine collagen (Type I and III) plus 8 supporting vitamins and minerals — each chosen for a specific role in skin, hair, or nail health. Every ingredient is dosed at meaningful levels backed by published research or EFSA-authorised health claims. Nothing is included as a label filler.

Why does the collagen dose matter more than anything else?

15,000mg of hydrolysed marine collagen is the foundation of Aura’s formula. Marine collagen is predominantly Type I and Type III — the collagen types that make up 80-90% of human dermal collagen. This is fundamentally important. Your skin needs Type I and III collagen to maintain structure, elasticity, and resilience. Animal collagen sources like beef or chicken contain primarily Type I with some Type II (cartilage collagen). Marine collagen, sourced from fish, is naturally high in both Type I and Type III, making it better matched to the collagen your skin actually contains.

The hydrolysis process breaks marine collagen down into small peptides during manufacturing — typically in the 2,000 to 5,000 Dalton molecular weight range. This enzymatic processing makes the peptides small enough for efficient absorption through the intestinal wall. Unhydrolysed collagen would be far too large to absorb. The hydrolysis is not optional — it is essential to bioavailability. Aura uses hydrolysed marine collagen specifically because this form can actually reach your bloodstream in meaningful quantities.

The 15,000mg dose exceeds every published clinical trial examining collagen supplementation. The highest-dosed studies used 10,000-12,000mg per day and showed improvements of 17-22% in skin elasticity and hydration. Aura sits above this evidence curve. In liquid form, this dose achieves approximately 80% assimilation at the intestinal level (León-López et al., 2019) — meaning approximately 12,000mg of the 15,000mg dose actually reaches your bloodstream. This is substantially higher than the doses used to demonstrate clinical efficacy.

What do the vitamins and minerals actually do?

Vitamin C is an essential co-factor for collagen synthesis. Without adequate Vitamin C, your body cannot form stable collagen molecules regardless of how much collagen peptide precursor you consume. Pullar et al. (2017) established this relationship clearly — Vitamin C is required for the enzyme prolyl hydroxylase to function, and this enzyme cross-links collagen molecules into stable, functional structures. If you are deficient in Vitamin C, you can take unlimited collagen but your body cannot construct functional collagen from it. Aura includes Vitamin C to ensure that the collagen substrate can be properly synthesized. The EFSA-authorised health claim states: “Vitamin C contributes to normal collagen formation for the normal function of skin.” This is not marketing language — it is a mechanistic statement of how Vitamin C functions.

Retinol (Vitamin A) at 100% NRV supports skin cell turnover and cellular differentiation. Retinol is one of the most well-researched anti-aging ingredients in dermatology, with decades of evidence supporting its role in maintaining skin architecture and promoting appropriate skin cell turnover. It works at the cellular level to help maintain the epidermis and support the barrier function of skin. Retinol is included in Aura to support the surface layers of skin while the collagen works on the deeper dermal structure.

Vitamin D3 at 700% NRV supports skin barrier function and immune regulation in the skin. The high NRV reflects the widespread Vitamin D deficiency in the UK, particularly during winter months when sun exposure is minimal. Vitamin D receptors are found throughout the skin, and Vitamin D plays crucial roles in maintaining the skin barrier and regulating immune responses within skin tissue. Aura’s high dose reflects both the typical deficiency levels in the population and the legitimate role Vitamin D plays in skin health.

Biotin (Vitamin B7) is one of the most frequently requested ingredients in hair and skin supplements, and for good reason. The EFSA-authorised claim states: “Biotin contributes to the maintenance of normal hair and skin.” Biotin is included in Aura at a meaningful dose rather than trace amounts — the dose is high enough to actually support its biological function rather than simply appearing on the label. Biotin supports keratin synthesis, which is essential for hair and nails.

Pantothenic Acid (Vitamin B5) carries the EFSA-authorised claim: “contributes to normal synthesis and metabolism of steroid hormones, vitamin D and some neurotransmitters.” It supports the body’s broader synthesis machinery — including the machinery that produces collagen and maintains skin structure. Pantothenic acid also supports skin hydration and barrier function.

Vitamin K2 works synergistically with Vitamin D3. While Vitamin D regulates calcium absorption, Vitamin K2 directs calcium metabolism and deposition. Together they support proper mineral metabolism, which plays an important role in bone health and cellular function, including skin cells. Vitamin K2 also supports vascular function, which is relevant to skin health.

Zinc at 100% NRV carries multiple EFSA-authorised claims: “contributes to the maintenance of normal skin, hair and nails.” Zinc is also essential for protein synthesis and immune function. Zinc deficiency is associated with poor wound healing and skin integrity issues. By including Zinc at 100% NRV, Aura ensures adequate supply for all of these zinc-dependent functions.

Selenium carries the EFSA-authorised claim: “contributes to the maintenance of normal hair and nails.” Selenium is also a critical component of selenoproteins, which have antioxidant properties and protect against oxidative damage to skin cells. UV exposure, pollution, and normal metabolism generate reactive oxygen species that damage skin. Selenium helps neutralize these threats.

Why is hyaluronic acid included alongside collagen?

Hyaluronic acid (HA) is the skin’s primary humectant — a molecule that attracts and holds water. A single gram of hyaluronic acid can hold up to one thousand times its weight in water. Collagen provides the structural scaffold of skin. Hyaluronic acid provides hydration within that structure. Together, they address the two main dimensions of skin aging: structure (collagen) and hydration (hyaluronic acid). This is why combining them makes biological sense — they work on different aspects of skin health.

Sato & Kinugasa (2025) published research in Nature’s Scientific Reports demonstrating that oral sodium hyaluronate improves skin hydration, barrier function, and visible signs of aging in healthy adults. Kawada et al. (2014) showed that ingested hyaluronic acid at 120mg daily produced statistically significant improvements in skin moisture content within 3-6 weeks in participants with dry skin. Hsu et al. (2023) reviewed the evidence comprehensively and confirmed that oral hyaluronic acid supplementation is effective for improving skin hydration.

Including hyaluronic acid in Aura means you are addressing both collagen density and hydration in a single daily shot. Rather than taking separate collagen and HA supplements, Aura provides both in a formulation designed to work together. The collagen rehydrates from the inside, and the hyaluronic acid amplifies the skin’s capacity to hold and retain that hydration.

How do all the ingredients work together?

The Aura formula is designed as an integrated system, not a collection of individual ingredients included for marketing appeal. Marine collagen provides the structural building blocks that your dermis needs. Vitamin C ensures those building blocks can be properly assembled into functional, cross-linked collagen molecules. Zinc and Selenium protect against oxidative damage that would otherwise degrade existing collagen and damage skin cells. Biotin supports hair and nails directly, addressing all three components of the “hair, skin, and nails” category. Hyaluronic acid hydrates the structure that collagen provides.

Vitamins A and D support skin cell turnover and barrier function at the epidermal level, while collagen works on the dermal level. Pantothenic acid supports the overall synthesis machinery your body uses to maintain all skin structures. The formula addresses collagen structure, protein synthesis, oxidative protection, hydration, cellular turnover, and barrier function — the key dimensions of skin aging.

Evening timing amplifies the formula’s design. Collagen synthesis and cellular repair peak during deep sleep, when growth hormone levels are elevated and cortisol levels are low. Taking Aura in the evening means this entire nutrient profile — the collagen substrate, the synthesis co-factors, the protective antioxidants, and the hydration support — is circulating during the deep sleep window when your body is most actively synthesizing collagen and repairing skin. This is not arbitrary timing. It is biologically aligned with your body’s own circadian rhythm of collagen synthesis.

People Also Ask

Why doesn’t Aura contain Vitamin E?

Aura’s formula focuses intentionally on nutrients with direct, EFSA-authorised roles in collagen synthesis, skin maintenance, and structural support. Vitamin E is a valuable antioxidant and is supported by research for skin health, but it is also widely available through diet in foods like nuts, seeds, and vegetable oils. Including it would add to the label and the cost without adding to the specific collagen-support and structural-protein mechanism that Aura is optimized for. The formula prioritizes depth over breadth — meaningful doses of carefully selected ingredients rather than trace amounts of many ingredients.

Is the Vitamin D3 dose safe at 700% NRV?

Yes. The Recommended Nutrient Intake (RNI) for Vitamin D is set conservatively at 5 micrograms (200 IU) daily, which has not been updated significantly in decades despite new evidence. The UK government’s Scientific Advisory Committee on Nutrition (SACN) recommends 10 micrograms daily as a more appropriate minimum, and many health professionals recommend higher intake, particularly for those with limited sun exposure or living in northern climates. The safe upper limit established by EFSA for Vitamin D3 supplementation is 100 micrograms daily. Aura’s dose is well within this safe range and reflects more contemporary scientific understanding of Vitamin D requirements.

Can I take Aura if I have a fish allergy?

No. Aura contains marine collagen, which is derived from fish. If you have a documented fish allergy, this product is not suitable for you and you should avoid it. Fish allergens are proteins, and while hydrolysis breaks down the collagen structure, allergen proteins may still be present in the final product. If you have a fish allergy, you might consider alternative collagen sources like bovine collagen, though these are Type I-heavy and less dermatologically optimal than marine collagen.

Are there any artificial additives?

Aura uses minimal additives: natural apple flavour, steviol glycosides and sucralose for sweetness, and organic raspberry, blueberry, and red beet powder for colour. There are no synthetic colours, no preservatives, and no artificial additives beyond these minimal flavouring and sweetening agents. The focus is on the active ingredients — the collagen, vitamins, minerals, and hyaluronic acid — rather than on packaging the supplement in a complex matrix of excipients.

Every ingredient in Aura is there for a documented reason — backed by published research or an EFSA-authorised health claim. The 15,000mg collagen dose exceeds published trial doses, the supporting nutrients ensure your body can actually use it, and the evening timing aligns with your body’s natural collagen synthesis peak.
