Often described as “beauty from within,” nutricosmetics are dietary supplements formulated to support hair, skin, and nail health through targeted nutraceutical ingredients. As beauty and wellness increasingly converge, more consumers are asking, “What are nutricosmetics?” and exploring holistic approaches to healthy aging and appearance.

Consumer demand for these products continues to rise, with market analyses projecting strong growth for the global nutricosmetics sector.¹ ²

This blog article will discuss key ingredients commonly used in nutricosmetics, popular nutricosmetic supplement formats, multi-ingredient formulations, and trends driving the nutricosmetics market.

What Are Nutricosmetics?

Nutricosmetics are ingestible products formulated with nutraceutical ingredients such as collagen peptides, antioxidants, vitamins, and botanicals to support beauty-from-within. Unlike topical products that act on the skin’s surface, nutricosmetics provide nutrients that may help nutritionally support and promote hair, skin, and nail health.

The concept is based on research suggesting that these nutraceuticals may influence physiological processes involved in maintaining a healthy appearance and normal skin structure.

How Nutricosmetic Supplements Work

A nutricosmetic supplement is formulated to provide targeted nutrients that support the normal structure and function of hair, skin, and nails. These ingredients can provide the nutritional building blocks involved in maintaining healthy skin structure, normal hair growth cycles, and nail integrity. After ingestion, they are absorbed through the digestive tract and distributed throughout the body, where they can participate in normal physiological processes.

When communicating product benefits, it is important to use appropriate structure-function language and avoid making medical or disease-related claims.

Ingredient form, dosage, and overall formulation can also influence bioavailability, or how effectively nutrients are absorbed and utilized. These products are typically available in a range of delivery formats, including tablets, capsules, gummies, powders, and functional beverages, giving consumers options that align with their preferences and lifestyles.

Key Ingredients Commonly Used in Nutricosmetics

A variety of nutricosmetic ingredients are commonly used to support normal body functions associated with skin, hair, and nail health. These include collagen peptides, hyaluronic acid, antioxidants, spermidine, biotin, and keratin.

Collagen Peptides

Beauty from within is a key trend driving the use of collagen peptides. Human clinical research has shown that supplementation with bovine-derived collagen peptides,³ ⁴ ⁵ collagen extract from chicken sternal cartilage,⁶ and marine collagen peptides⁷ ⁸ ⁹ may support a range of appearance-related benefits.

Depending on the source and study, reported outcomes have included improvements in the appearance of wrinkles, skin dryness and scaling, skin moisture, UV-related spots, cellulite, hair thickness, and nail growth.

Polyphenols

A study¹⁰ found that oral cacao powder rich in flavonoids and polyphenols significantly improved skin hydration, moisture retention, and the appearance of wrinkles. Another study¹¹ evaluating high-flavanol chocolate reported that cocoa flavanols may support skin photoprotection, while also assessing improvements in skin elasticity and hydration.

Exploring BCAA Types and Their Unique Benefits

In addition, a 2025 systematic review and meta-analysis¹² of dietary supplements for skin photoaging found that oral flavanols and other polyphenol supplements were associated with improvements in skin photoaging and overall skin elasticity compared with placebo.

Hyaluronic Acid

Hyaluronic acid is a natural substance found in human skin,¹³ that binds to water to help maintain hydration.¹⁴ ¹⁵ It helps the skin retain moisture and may reduce the appearance of fine lines and wrinkles.¹⁶ However, hyaluronic acid levels in the skin decline with age.¹⁷

Animal research¹⁸ has shown that orally supplemented hyaluronic acid can reach the skin. Human clinical research¹⁹ has also shown that a specific hyaluronic acid material significantly decreased the appearance of wrinkles, increased skin moisture content and elasticity, and reduced trans epidermal water loss compared with placebo.

Antioxidants (e.g., Lycopene, Beta-Carotene, Vitamin E, Selenium)

Two different studies examined the effects of supplementation with a combination of the antioxidants lycopene, beta-carotene, vitamin E and selenium on skin health.

The first study²⁰ found that the antioxidant combination reduced UV-induced skin redness, suggesting a potential protective effect against UV-related skin damage.

The second placebo-controlled study²¹ found that the antioxidant combination significantly increased skin density and thickness, parameters associated with skin structure and appearance. In addition, supplementation significantly reduced skin scaling and roughness.

Spermidine

Research²² has shown that spermidine can upregulate the expression of epithelial stem cell-associated keratins involved in normal hair growth.

Studies²³ ²⁴ have also shown that supplementation with spermidine, alone or in combination with nutrients such as methionine, vitamins, minerals, and polyphenols, may help reduce hair loss, increase hair shaft diameter, and prolong the anagen, or active growth, phase of the hair cycle.

In another study,²⁵ a rice germ extract source of spermidine was shown to increase nail growth and nail strength, as well as increase hair growth and hair thickness, while reducing hair shedding.

Biotin & Keratin

Biotin is involved in enzyme activity that supports the production of keratin, a structural protein found in hair.²⁶ Biotin deficiency may also contribute to hair loss.²⁷ Although biotin is one of the most popular nutrients used for hair health, there is little evidence that supplementation provides additional hair benefits in healthy individuals who already consume sufficient amounts.²⁸

Studies²⁹ ³⁰ have, however, shown that biotin supplementation may support nail health. Other research³¹ ³² has shown that supplementation with 500 mg of a specific keratin hydrolysate, combined with zinc, niacin, copper, pantothenic acid, vitamin B6, and biotin, may help reduce hair shedding and support the normal hair growth cycle.

Glutathione

Glutathione is an antioxidant that plays important roles in immune function and numerous other physiological processes.³³ ³⁴ ³⁵ Research has also examined its potential effects on skin appearance.

In one study,³⁶ glutathione supplementation was associated with reductions in skin pigmentation, under-eye wrinkles, and pore size. Another study³⁷ found that supplementation reduced UV-induced skin pigmentation compared with placebo. Additional research has reported similar findings.³⁸

Most Popular Nutricosmetic Supplement Formats

Tablets, capsules, and powders tend to be among the most popular delivery formats for these products. The best option often depends on the ingredients, serving size, and overall formulation.

For example, if the total ingredient load is around 1,000 mg, it may fit comfortably into two size 00 capsules. By contrast, a formula containing 2.5 g of collagen peptides may be better suited to multiple tablets or a powdered format. A qualified contract development and manufacturing organization (CDMO) can help determine the most appropriate dosage form based on formulation requirements and product goals.

Capsules

Hard gelatin or vegetarian capsules are versatile delivery formats commonly used in dietary supplements because they can accommodate powders, granules, and multi-ingredient blends. Their two-piece design supports efficient filling and precise dosing while offering compatibility with a wide range of vitamins, minerals, botanicals, amino acids, and other nutraceutical compounds.

Capsules also provide formulation flexibility, ease of manufacturing, and a convenient dosage form for combining multiple active ingredients. Once ingested, the capsule shell dissolves in the gastrointestinal tract, allowing the contents to be released for absorption and utilization.

Tablets

Tablets provide a stable and cost-effective delivery format while enabling precise dosing and consistent product quality. They can accommodate a wide range of vitamins, minerals, botanicals, and specialty ingredients commonly used to support hair, skin, and nail health.

Excipients, binding agents, and disintegrants help support tablet strength, uniformity, manufacturability, and appropriate breakdown after ingestion. Coating technologies can also improve appearance, mask unpleasant tastes or odors, enhance swallowability, and help protect sensitive ingredients from moisture, oxygen, and light, supporting product stability throughout shelf life.

In addition to conventional tablets, other options include chewable tablets, orally disintegrating tablets, also known as fast-melt or quick-dissolve tablets, and effervescent tablets.

Powders

Powder formulations offer considerable flexibility by allowing customizable dosing and the incorporation of multiple ingredients into a single serving. Because powders are typically dispersed in liquid before consumption, they can offer advantages in dissolution compared with some solid dosage forms. Formulators must consider ingredient stability, moisture sensitivity, and interactions among active compounds to maintain product quality throughout shelf life.

Taste-masking technologies, flavors, and sweeteners can be used to improve palatability, while solubility and dispersibility are important considerations for powders intended to be mixed with water, beverages, smoothies, or other liquids.

Vitaquest has expertise in particle creation, modification, and manufacturing using technologies such as fluid bed processing, oscillation, and roll compaction. Capabilities include wet and dry granulation, agglomeration, microencapsulation, spray coating, particle sizing, air drying, and specialty blending of liquid and powder components.

Depending on the formulation, these technologies can help improve powder flow and solubility, protect ingredients from degradation or interaction with other components, mask undesirable tastes, and support product stability.

Multi-Ingredient Formulations in Nutricosmetic Supplements

While single-ingredient products can support beauty-from-within positioning, multi-ingredient formulations are common in this category. There are several reasons for this. Nutraceutical ingredients may work through different mechanisms of action, complement one another, or support multiple areas such as skin, hair, and nail health.

Combining ingredients can also allow formulators to target a specific benefit from multiple angles.

When supported by appropriate research and formulation rationale, this approach may help create a more comprehensive product offering.

Trends Driving the Nutricosmetics Market

The global nutricosmetics market is projected to grow from $8.32 billion in 2026 to $15.98 billion by 2034, representing a compound annual growth rate (CAGR) of 8.50%, driven in part by demand for scientifically supported solutions that promote skin, hair, and nail health from within.³⁹ This aligns with market research reporting that 72% of women purchasing natural and organic beauty products believe in the concept of beauty from within, supporting demand for ingestible beauty solutions.⁴⁰

Consumers are also increasingly viewing skin, hair, and nail health as reflections of overall wellness. Industry experts note that modern consumers see beauty, health, and wellness as interconnected, helping drive interest in ingestible products such as collagen supplements, antioxidants, and other skin-support nutrients.⁴¹

Another trend is the growing interest in combining ingestible and topical beauty products as part of a more comprehensive approach. These products may provide complementary support by addressing appearance from different angles. For brands, this creates opportunities to develop products that fit within broader beauty and wellness routines while appealing to consumers interested in both inside-out and outside-in approaches to personal care.
