Real beauty comes from within, so supplementation is one of the best ways to improve skin’s well-being — complementing your extensive routine with a slew of ingestible, radiance- and elasticity-boosting ingredients like collagen, peptides, hyaluronic acid, and NAD, across formats such as powders, hydration packets, capsules, and even gummies.
Finding supplements for skin that will align with your goals is no walk in the park, as this is one of wellness‘ hottest categories, and, understandably, hundreds of brands are hopping on the bandwagon as we speak. But iHerb, a global online retailer specializing in vitamins, minerals, and other health solutions, is here to simplify the process: getting you one purchase closer to the complexion of your dreams.
Right now, you can build out your supplement regimen for less on iHerb’s website, since it just kicked off a 30th Anniversary Sale that’s slashing prices by up to 30 percent on approximately 20,000 products — read: personal care, pet grooming essentials, protein chips, the best anti-aging serums on the market, and beyond — from over 600 participating brands.

Best Skin Supplements to Shop at iHerb’s Anniversary Sale 2026

best peptide supplement
Vital Proteins Collagen Peptides Supplement
Over 10,000 units of this powder were bought in the last 30 days, and its hype is nothing if not well-warranted. The kosher-, gluten-, dairy-, and sugar-free supplement has a 20-ounce volume (that’s about 28 servings) and promises to support skin, bones, hair, nails, and joints alike with its 20 grams of collagen peptides per serving. These overachieving proteins are linked to optimized skin hydration-slash-elasticity and bone mineral density — results that you’re sure to experience with consistent intake of the powder, which can be mixed into everything from water and coffee to smoothies and oatmeal.
The pictured iteration is flavorless, but you can also stock up on this Vital Proteins fan favorite in chocolate, lemon, or salted caramel at iHerb.

best skin hydration supplement
k2o by Sprinter Advanced Skin Hydration Mix Supplement, Strawberry Lychee
k2o is Kylie Jenner’s line of beauty-forward, on-the-go drink mixes and the latest manifestation of her alcohol brand Sprinter. Above is a popular formula in a desirable flavor, featuring a blend of five electrolytes, hyaluronic acid, and bioactive collagen peptides. In turn, it serves multiple purposes — enhancing internal hydration, helping the skin barrier retain moisture, and reducing the appearance of fine lines.
To savor that tropical-coded strawberry lychee taste and the sticks’ rolodex of benefits, simply mix one packet into 16 ounces of water, pouring the final concoction over ice. There are no bad-for-you additions in sight, only natural flavors, vegetable juice for color, and citric acid for a pleasant tartness.

best collagen supplement
Ancient Nutrition Beauty Within Multi Collagen Protein Supplement, Guava Passionfruit
If your skin has been struggling to generate collagen independently, aid the efforts with Ancient Nutrition’s Beauty Within Multi Collagen Protein — a powder made up of clinically studied contents (specifically, 10 types of food-sourced collagen) that lead to better outcomes for skin, yes, but also hair, joints, and digestion. According to the brand, the dietary supplement “improves the appearance of crow’s feet after four weeks and skin tone after eight weeks,” thereby enriching the work of your go-to LED mask or facial device.
Vitamin C and probiotics round out the product’s ingredient list, so you better believe greater glowiness and a more resilient skin barrier will be yours to relish in due time, too.

best nad supplement
ProHealth Longevity NAD Triple Boost Supplement With NMN
NAD is a naturally occurring coenzyme that’s vital to processes like metabolism and DNA repair. Found in every living cell, NAD shuttles around other cellular components to turn food into energy, fixes damaged genetic material, and otherwise ensures your body’s firing on all cylinders. NAD+ is the active form of NAD, and it is just this element that ProHealth Longevity’s NAD Triple Boost Supplement concentrates on.
The offering is so effective and coveted, only eight bottles are still in stock at iHerb, so waste no time in grabbing a few of your own while they’re 30 percent off. Third-party lab-tested and created in a facility that follows Good Manufacturing Practices (GMP), the capsules stabilize NAD levels amidst age-related declines, speed up the coenzyme’s production, and convert it into the kind of energy that can last all day: by tapping NMN, a molecule that your bod utilizes to make NAD.
Crucially, NAD contributes to healthy cellular aging, promotes cellular turnover, and can fix cellular damage caused by the sun — making it a skin care salve through and through. Let your own skin feel the difference by taking three caplets per day with food.

best gummy supplement
Nature’s Way Alive! Hair, Skin & Nails Supplement Gummies
As iHerb’s #1 bestseller in the “Hair, Skin & Nails Formulas” category, this gummy supplement tastes great and performs even better. Chewing two gummies a day will unlock a plethora of perks such as lustrous hair, a dewy complexion, and fortified hair follicles — courtesy of their vitamin C, hydrolyzed collagen, and biotin inclusions. It’s easy to mistake this baby for a sweet treat, but know that it swaps unnecessary sugars for a complex of fruits and vegetables (think carrots, açaí, beets, brussels sprouts, and plums) that will diversify your overall diet.
Still hesitant to incorporate the Nature’s Way top hit into your habit-stacking rituals? iHerb delivers peace of mind with its Quality Promise: encompassing freshness, authenticity, and rigorous testing.

best vitamin supplement
Vital Nutrients Vitamin A Softgels Supplement
The star of the show here is fish liver oil–derived vitamin A, plain and simple. Lacking in bells and whistles, the Vital Nutrients supplement can fully dedicate itself to one central task: propping up the amount of vitamin A in your body. For those not aware, this essential nutrient plays a key role in vision, immune function, and skin health — cutting back on hyperpigmentation, fighting oxidative stress, addressing acne, and even tackling conditions like psoriasis.
Vital Nutrients has made sure that the softgels’ vitamin A is not only bioavailable but also of an ideal dosage, because you deserve efficiency and potency when it comes to supplements for skin.

best biotin supplement
Micro Ingredients Biotin Softgels Supplement
Meet Micro Ingredients’ Biotin Softgels, which are sold at iHerb with enough servings to last you a whole year and pride themselves on “exceptional quality,” as the clean-label supplements company puts it. Combining 10,000 micrograms of hyaluronic acid (for flooding skin cells with moisture) and 25 milligrams of biotin (also for keeping the skin barrier thoroughly quenched) in each gel capsule, the non-GMO buy has a tight yet targeted resume, ultimately revealing a plumper, glowier face.
Adding this biotin supplement to cart will also put you just a dollar away from iHerb’s free shipping threshold, as all orders over $25 qualify for this indulgence. Translation: Pair it with more editor-approved selections in our roundup and prepare to greet your most nourished skin to date.
