Our collagen powder targets nail (and skin and hair) health from multiple angles: There's 17.7 grams of pasture-raised, grass-fed bovine collagen peptides (delivering types I and III collagen); vitamins C and E for enhanced collagen production and antioxidant support; hyaluronic acid for hydration; biotin to strengthen nails; and the protein building block L-glutamine. Plus, you can trust that each ingredient is rooted in science, and the excipients (aka, the "other" ingredients on the label) are clean and of the highest quality. A star supplement, we'd say.*

This tasty gummy features biotin, vitamin C, and folic acid for strong nails, as well as pre- and probiotics to support gut health (a welcome added benefit, don't you think?). As you chew on the candy-like gummy (serving size equals two gummies), take note of the tart flavor—it's all thanks to a berry antioxidant blend of cranberry, raspberry, cherry, strawberry, blueberry, and elderberry extracts.*

While bovine collagen peptides tend to be the most researched and potent, marine collagen is a great option for those who follow a pescatarian diet. The other main ingredient is the brand's signature crushed pearl powder (come on, that just sounds luxurious), which is chock-full of minerals like calcium.* 

These capsules contain Cynatine®, a clinically tested and bioavailable form of solubilized keratin, to help strengthen your hair and nails. Other star players in this multi-ingredient formula include biotin, MSM, hyaluronic acid, vitamins C and E, and horsetail extract (to name a few)—which research shows can help enhance nail health.*

We've said it before, and we'll say it again: There is no such thing as vegan collagen. There are vegan ingredients that support collagen health—like vitamins C and E for collagen synthesis or botanical antioxidants to protect the collagen you have from oxidative damage—but the actual collagen itself cannot be sourced from plants. That said, this supplement contains ingredients to bolster your body's natural production of collagen, like vitamin C, as well as a B complex and key amino acids. We should note that each packet contains eight capsules—something to keep in mind in case you're looking for single-capsule doses.*

These USDA-certified organic tablets contain 2,500 mcg of biotin, along with antioxidants from pomegranate, turmeric, amla (a berry that is rich in vitamin C), and green and rooibos teas. It's marketed as a collagen builder, so know that while there are no collagen peptides inside the formula, the ingredients are meant to support and protect your body's natural source.* 

To support a smooth, moisturized nail plate, look for a supplement with fatty acids—specifically, these softgels contain DHA and EPA, along with biotin, calcium, and vitamins C and E to strengthen and hydrate the nails, along with other essential prenatal micronutrients like iron, vitamin D3, and much more.*

Soluble keratin is the star ingredient here (500 mg!), but the formula is enhanced with biotin and resveratrol (a potent polyphenol) to support and protect healthy nail beds. Not only are you replenishing your body's keratin with this supplement, but it also helps encourage your body's natural production of the protein—so this is a formula with multiple avenues for nail health.*
