Do beauty supplements replace a good skincare routine?

No—they complement each other. A topical skincare routine addresses the surface layer of skin: cleansing, protecting from UV exposure, and providing surface-level hydration. Beauty supplements work at the cellular and structural level, supporting the production of collagen, the hydration of cells from within, and the protection of cells from oxidative damage before it reaches the surface. The most effective approach combines good topical habits with targeted internal nutrition—because lasting skin health is built from both directions simultaneously.*

Can men use beauty supplements too?

Absolutely. Hair, skin, and nail health is not gender-specific, and the nutrients in these formulas—silica for collagen support, omega-7 for hydration, antioxidant berries for oxidative protection, biotin for keratin—are relevant for everyone. Men concerned with thinning hair, brittle nails, or skin aging will benefit from the same biological support pathways as women. Terry Naturally's Hair, Skin & Nail Essentials, Silica-20™, and Omega-7 are all appropriate for all adults.*

How long does it take to see results from beauty supplements?

Genuine structural improvements—stronger nails, less hair breakage, improved skin tone and moisture—typically emerge over time with consistent daily use. Nails grow approximately 3–4 mm per month, and a full new hair growth cycle takes months—so changes in nail strength or hair quality require time to become visible. Skin renewal is faster, and improvements in hydration and radiance from omega-7 and antioxidant support may be noticeable somewhat sooner. Consistency is the key factor.*

What is sea buckthorn and why is it in a beauty supplement?

Sea buckthorn (Hippophae rhamnoides) is a small orange berry known for an exceptionally dense concentration of bioactive compounds. It's one of the few plant-based sources of omega-7 fatty acids (palmitoleic acid), and contains beneficial bioactive components including vitamins A, C, and E, flavonoids, carotenoids, plant sterols, and essential fatty acids. Omega-7 fatty acids are important for the integrity of cell membranes throughout the body—including skin cells—where they help cells hold on to moisture. This translates into more hydrated, supple skin from the inside out.*

Why is silica better than taking a collagen supplement directly?

Collagen is a large protein, and when consumed as a supplement, it is broken down into amino acids and peptides during digestion—like any other dietary protein. Whether those amino acids are then reassembled into collagen in the body depends on the availability of cofactors, including silica. Silica plays a direct structural role in the collagen synthesis process itself. Optimizing silica levels gives the body the raw material it needs to build collagen at its own optimal rate—a more targeted and efficient approach than simply providing amino acid building blocks. The two can also be taken together for complementary support.*

What supplements are best for hair, skin, and nails?

The most effective approach combines nutrients that address collagen synthesis, cellular hydration, and oxidative protection. Silica (particularly from horsetail plant) supports collagen production directly—and Terry Naturally's Silica-20™ has been shown to support collagen production by up to 50%.† Omega-7 fatty acids from sea buckthorn support cell membrane hydration, which directly influences skin moisture and suppleness. Antioxidants like those from maqui berry and aronia berry protect skin cells from oxidative stress and support a radiant, even appearance. Biotin and millet oil round out the formula by supporting keratin production for strong hair and nails.* †In vitro evaluation on cultured human bone.

3 Targeted beauty formulas — each addressing a different pathway to healthier hair, skin, and nails*

Up to 50% Increase in collagen production supported by Silica-20™†

Inside-out Real hair, skin, and nail health is built from nutrition — not just topical creams

Summary

Healthy hair, skin, and nails are built from the inside out — no cream or serum can substitute for the right nutrition. This guide covers three Terry Naturally beauty supplements, each addressing a different layer: Silica-20™ for collagen support, Omega-7 from sea buckthorn for cellular hydration, and Hair, Skin & Nail Essentials for antioxidant protection and keratin support.*†^ Results build over weeks and months of consistent use.

Summarize with:

The beauty supplement market is loud—and often confusing. Influencers promote different products daily, ingredient trends come and go, and the shelf at any health food store can feel overwhelming. But the science of healthy hair, skin, and nails is actually quite clear: these structures are built from the inside out, and no topical product can substitute for the right nutritional foundation. Terry Naturally offers three research-supported beauty supplements that address the root causes of dull, brittle, or aging hair, skin, and nails—each one targeting a distinct pathway.*

Why nutrition is the foundation of healthy hair, skin, and nails

Hair, skin, and nails are all built from structural proteins—primarily collagen (the most abundant protein in the body, providing elasticity and firmness to skin) and keratin (the protein that forms the actual structure of hair and nails). Both require a steady supply of specific nutrients to be produced and maintained. When those nutrients are consistently available, the results show: skin holds moisture and resilience, hair grows with strength and volume, and nails resist breaking.

Topical creams and serums can support the surface layer of skin, but they cannot rebuild the deeper structural architecture where true skin health originates. That happens through nutrition—specifically, through the targeted nutrients that support collagen synthesis, maintain cellular hydration, and help protect cells from oxidative damage.*

Silica-20™: The collagen support most people have never heard of*

Collagen supplements have become enormously popular—but the best way to support collagen production isn't necessarily to take collagen peptides directly. The body's ability to synthesize collagen depends on the availability of key cofactors, and silica is one of the most important. Silica is a trace mineral that plays a direct role in collagen formation—and research has shown that optimizing silica levels can support collagen production in human tissue.*

Silica-20™ features a superior, bioavailable form of silica sourced from the horsetail plant, combined with beneficial trace minerals from the sea. Just two small tablets daily deliver a standardized amount of silica shown in research to support collagen production by up to 50%.† This matters for skin—supporting elasticity and a youthful appearance—and equally for hair and nails, which depend on collagen's structural role in the follicle bed and nail matrix.*

Silica is technically obtainable from food—but the amount absorbed from dietary sources is minimal. You would need to consume roughly 50 bananas to absorb approximately 8 mg of silica from food, illustrating why a supplemental source is so practical for anyone serious about collagen support.* Silica-20 is a vegan formula, making it accessible regardless of dietary preference.

Omega-7: The beauty fatty acid hiding in plain sight

Most people know about omega-3s for heart and brain health. Far fewer know about omega-7 fatty acids—a class of fats found in sea buckthorn berry that are increasingly recognized as the 'beauty omegas' for their role in skin hydration and cellular health.*

Omega-7 fatty acids are naturally present in cell membrane walls throughout the body, where they help cells retain moisture. This is especially relevant for skin cells, where adequate hydration directly influences how skin looks and feels—its suppleness, smoothness, and resilience. Dry, dull, or flaky skin is often a sign of cells struggling to maintain moisture at the membrane level, and omega-7 fatty acids support this function directly.*

Terry Naturally Omega-7 is sourced from the sea buckthorn berry—a small, bright orange berry often called a 'nutrient bomb' for its exceptional concentration of bioactive compounds. Sea buckthorn contain beneficial bioactive components, including vitamins, antioxidants, essential fatty acids, and plant sterols. Together, these compounds support supple, hydrated skin from head to toe, providing the kind of deep cellular moisture that topical moisturizers can't replicate.*

Hair, Skin & Nail Essentials: Berry antioxidants for a radiant appearance*

The third pillar of Terry Naturally's beauty supplement approach is antioxidant protection^—specifically the targeted antioxidant compounds found in deeply pigmented berries. Hair, Skin & Nail Essentials combines clinically studied maqui berry with aronia berry extract AB40™, plus additional skin-supporting nutrients including biotin and millet oil.*

The maqui berry extract in this formula provides delphinidins—a class of anthocyanin antioxidants that deliver strong protection against oxidative stress and have been studied for their support of radiant skin, even skin tone, and youthful appearance. These aren't just generic antioxidant claims—delphinidins are some of the most potent flavonoid compounds studied specifically in the context of skin health, and their inclusion in a concentrated, standardized extract gives this formula a meaningful level of skin-supportive activity.*

Aronia berry extract AB40™ complements maqui berry with its own rich supply of anthocyanins, promoting intensive skin support and contributing to the kind of glow that reflects genuine cellular health rather than surface-level cosmetic effect. Biotin rounds out the formula by supporting keratin production—the structural protein that directly builds hair and nails—while millet oil provides additional nourishment for hair growth and volume.*

How the three formulas build beauty from within*

Silica supports collagen

Silica is a trace mineral your body needs to make collagen — the protein that gives skin elasticity and firmness. Silica-20™ delivers a bioavailable form from horsetail plant, supporting collagen production by up to 50%.*†

Omega-7 hydrates cells

Omega-7 fatty acids from sea buckthorn become part of your cell membranes — including skin cells — helping them retain moisture. The result: supple, hydrated skin from head to toe, in a way creams can't replicate.*

Berry antioxidants protect*

Maqui berry delivers delphinidins — potent antioxidants studied for skin support, even tone, and radiance.^ Aronia berry AB40™ adds more anthocyanins, while biotin and millet oil support the keratin that builds hair and nails.*

Building a beauty supplement routine that works

Each of these three formulas addresses a different dimension of hair, skin, and nail health. Silica-20 targets collagen synthesis and structural support. Omega-7 addresses cellular hydration and moisture retention. Hair, Skin & Nail Essentials provides antioxidant protection and keratin support.^ Together, they create a comprehensive foundation that works from multiple angles—the way effective, science-backed nutrition always does.*

The most important thing to understand about beauty supplements is that they work cumulatively. Collagen synthesis improves over weeks and months of consistent silica intake. Cellular hydration builds with sustained omega-7 use. Antioxidant protection accumulates over time.^ Results from these formulas reflect the same principle as good skincare: consistency over time produces genuine improvement, not overnight transformation.*
