Best Collagen for Women
Last Updated: [09/24/26]
6 Things the Best Collagen for Women Has in Common (And the One Scoop That Has All Six)
Most collagen powders promise better hair, skin and nails, but almost none deliver. There are six reasons why. A lot of what gets sold as "collagen" is made cheap, produced to sell, and never formulated to work. Here's how you tell the difference before you buy.
You Know Exactly Where It Comes From
Most collagen on the shelf is bovine, made from cattle hides left over from the beef and leather industry. Plenty of cheaper marine powders don't even name the fish. The best collagen tells you exactly what it's made from and where it was caught.
How to checkLook for the fish species and the ocean it came from, named on the bag or the product page.
holi (mane) is made from wild-caught North Atlantic cod, pollock and haddock. It's non-GMO and kosher.
It's a Full Collagen Complex, Not Just Type I
Your body makes more than one kind of collagen, and each one has a different job. Type I keeps skin firm, type III gives it bounce, and type IV helps hold its layers together. Most marine collagen is almost entirely type I, from one narrow source. A formula with more than one type gives your body a broader mix of building blocks to work with.
How to checkLook for the collagen types on the label. If none are listed, the brand isn't telling you.
holi (mane) has types I, II, III and IV, listed right on the label.
Real Grams of Protein per Serving
The amount is the whole point. Skin studies on collagen usually use 2.5 to 10 grams a day, and some gummies and capsules give you a gram or two per serving. Your hair and nails are made of protein too, so a scoop that's light on it is mostly packaging.
How to checkSkip the front of the bag. Find grams of protein per serving on the supplement facts panel.
holi (mane) gives you 16 to 24 grams of protein in two to three scoops.

It Brings the Glow, Not Just the Protein
Collagen gives your skin, hair and nails protein to work with, and that's only half of it. Pearl adds what collagen doesn't have. You get calcium and 30+ trace minerals, including magnesium and silica, plus antioxidant support. In a small 8-week placebo-controlled trial, people taking pearl powder showed higher antioxidant activity. It's also been a beauty staple for more than a thousand years, prized for luminous skin.
How to checkFlip to the ingredient list. If collagen is the only ingredient, you're getting protein and nothing else. Look for a formula that adds minerals and antioxidant support in the same scoop.
holi (mane) pairs marine collagen with saltwater pearl, so you get protein, 30+ trace minerals and antioxidant support in one scoop, without buying a separate pearl powder. We use saltwater pearl, about 10 times the cost of the freshwater pearl most brands use.
A Taste You Won't Notice
The best collagen is the one you'll take every day. Bovine powders can leave an aftertaste and some marine powders taste fishy, and that's usually when people start skipping days.
How to checkSearch the reviews for "aftertaste" and "fishy" before you buy.
holi (mane) is odorless and close to tasteless. Stir it into your latte, matcha or smoothie and you won't know it's there.
Enough to Take It for 90 Days
Collagen works on your body's timeline. Nails usually change first, within a few weeks, and skin and hair take a few months, which is why many collagen studies run 8 to 12 weeks.
How to checkCompare the cost per day over 90 days, not the price of one bag.
Our 90-day supply covers the full window, and at $2.80 a day it's the best value.
