There’s no shortage of powders, capsules and “beauty gummies” promising better skin from within. But while ingestible beauty is having a moment, the reality is far less about trends and far more about fundamentals.
To separate marketing from evidence, I spoke with naturopath Brie Brazenor from Baseline Naturopathics, who takes a science backed, whole body approach to skin health.
At its core, she explains, skin is a reflection of what’s happening internally, from digestion and nutrient status to inflammation and hormones. It’s this understanding that’s driving the rise of ingestible beauty, shifting the focus from quick topical fixes to supporting the body’s underlying processes.
Rather than chasing trends, Brazenor points to a core group of nutrients with consistent evidence behind them. Vitamin C, vitamin A, zinc, omega 3 fatty acids, polyphenols, vitamin E and collagen all play a role.
“These nutrients contribute to both the synthesis of skin, supporting the production, repair and regeneration of skin tissue, as well as the protection of skin,” she says.
Put simply, some nutrients help build skin, while others help defend it. Collagen, vitamin C and vitamin A are central to collagen production, while omega 3s, vitamin E, zinc and polyphenols work to protect against inflammation, environmental damage and premature ageing.
Collagen, in particular, has become the headline act in ingestible beauty and according to Brazenor, it is one trend that holds up under scrutiny.
“There is now high-quality evidence supporting collagen for skin health,” she says. “It provides key amino acids that form the building blocks of the skin’s collagen matrix.”
Research shows improvements in skin elasticity, hydration and wrinkle depth can begin in as little as four weeks, with relatively low daily doses and stronger results over time. Some studies also suggest these benefits can persist even after supplementation stops, pointing to longer term structural changes rather than short term hydration.
Not every ingredient that appears in beauty supplements carries the same weight. Biotin is often included but tends to be effective only in cases of deficiency, something that is relatively uncommon in otherwise healthy adults. Hyaluronic acid remains a standout in topical skincare, but when taken internally, the evidence is still limited. Marine collagen is less about effectiveness and more about preference, offering an alternative source for those who avoid bovine products, with similar outcomes.
When it comes to results, there is no one size fits all timeline. Skin has a relatively fast turnover, so some people may notice subtle improvements within a few weeks, but this depends heavily on individual health, nutrient status and what is being addressed.
Where many people go wrong is in the products themselves. Brazenor emphasises that quality and dose matter far more than clever packaging.
“Look for products with minimal fillers and check the equivalent to amount on the label so you know how much of the active ingredient you are actually getting,” she says.
It is also where many trend driven products fall short, prioritising flavour and marketing over formulations that actually deliver.
If there is one point, Brie is most clear on, it is that supplements are not the foundation of good skin.
“Healthy skin primarily comes from diet and lifestyle,” she says.
That means focusing on the basics, a wholefood, varied diet rich in colourful fruits and vegetables, healthy fats and adequate protein, alongside hydration, sleep and sun protection. Supplements can play a role, but they work best as support, not a shortcut.
If you are looking to support your skin from within, these are the products worth considering, focusing on collagen, antioxidants and essential fatty acids.
Happy Mammoth Prebiotic Collagen Protein Price $79.99
BUY IT HERE
A multi-tasking powder that combines collagen with prebiotics, supporting both skin structure and gut health. Given the strong link between digestion and skin, this is a more considered option than standalone collagen. Easy to add to smoothies or coffee, and a good choice if you are looking to support both gut and skin in one step. What sets it apart is the inclusion of prebiotics, which help feed beneficial gut bacteria, something often overlooked in beauty supplements. It also delivers a functional dose of collagen rather than token amounts, which is where many products fall short.
The Holistic Ingredient Marine Collagen with Hyaluronic Acid Price from $62.99
BUY IT HERE
A marine based collagen option for those who prefer not to use bovine sources. While hyaluronic acid is better supported topically than internally, the collagen component still delivers the key amino acids needed for skin structure, hydration and elasticity. Marine collagen is typically more easily absorbed due to its smaller peptide size, making it a popular choice for those focused on skin specific benefits. The addition of hyaluronic acid leans into hydration support, even if the strongest evidence still sits with topical use.
Anthogenol Capsules From $86.96
BUY IT HERE
A potent antioxidant supplement derived from pine bark extract. Rich in polyphenols, it helps combat oxidative stress, one of the major contributors to skin ageing, and supports overall skin resilience. It is particularly known for supporting circulation, which can have a flow on effect for skin health and clarity. As an antioxidant focused supplement, it complements collagen by helping protect the skin you are working to build.
Nordic Ultra Omega Lemon Soft Gels $67.35
BUY IT HERE
High quality omega 3 fatty acids to support skin barrier function and reduce inflammation. Particularly beneficial for dry, reactive or ageing skin where maintaining hydration and calmness is key. Nordic Naturals is known for its purity and low oxidation fish oils, which is critical when it comes to effectiveness. The lemon flavour also makes it more palatable than standard fish oil, which can be a barrier for consistency.
Fusion Health Hair, Skin and Nails Price $71.99
BUY IT HERE
A broad spectrum formula containing a mix of vitamins and minerals designed to support hair strength, nail health and skin integrity. Best suited if you suspect you may be lacking in key nutrients rather than as a one size fits all solution. It includes key nutrients like zinc and vitamin C, which play roles in both skin repair and protection. As with most combination formulas, the effectiveness comes down to whether the doses are therapeutic for your individual needs.
Mother SPF Natural Physical Sunscreen SPF 50 Price $52
BUY IT HERE
Because no supplement replaces daily sun protection. This zinc based sunscreen provides broad spectrum protection without chemical filters, making it a solid everyday option to prevent premature ageing. Physical sunscreens like this sit on the skin to reflect UV rather than absorb it, which can be gentler for sensitive skin. It also aligns with a prevention first approach, still the most effective anti ageing strategy we have.
