The nails that peel.
The mirror at 6am.
60 gummies · 2 per day · biotin + marine collagen + vitamin C
It's a slow build of little things — the brush has more hair in it than it used to, the polish chips by Tuesday, the skin looks tired in the photo your friend posted. Two berry gummies a day for the four nutrients beauty science keeps coming back to. The kind of routine you can do over coffee, not at a clinic.

A quieter system
Three ways the shift shows up.
Skin
For the photo you almost untagged.
Marine collagen peptides feed your skin's own collagen-building work; vitamin C is the partner that makes the work happen. The pair every dermatologist on TikTok keeps mentioning.
Nails
The polish lasts the week.
Brittle, peeling nails are often a quiet zinc shortfall — and a cheap fix. Two months in, the nail tech notices before you do.

What's inside
The label is the whole story.
Every ingredient, the form we use, the dose per serving, the mechanism that makes it relevant, and the peer-reviewed study that backs it.
1000 mg per serving
Marine Collagen Peptides
Form: 1,000 mg hydrolysed marine collagen (per 2-gummy serving)
Hydrolysed collagen peptides from sustainable wild-caught fish sources. Studied for supporting the body's own collagen-synthesis pathway — skin elasticity, hair quality, and nail strength.

Biotin (Vitamin B7)
Form: 5,000 mcg biotin (per 2-gummy serving)
An essential B-vitamin cofactor in keratin synthesis. Studied as foundational support for hair and nail integrity — particularly in those with mild biotin insufficiency.
A review of the use of biotin for hair loss · Skin Appendage Disorders, 201760 mg per serving
Vitamin C (Ascorbic Acid)
Form: 60 mg ascorbic acid (per 2-gummy serving)
An essential cofactor for collagen synthesis. Without sufficient vitamin C, the body cannot stabilise the collagen triple-helix. Pairs with marine collagen by biochemical necessity.

Zinc (as zinc gluconate)
Form: 5 mg elemental zinc (per 2-gummy serving)
An essential trace mineral involved in skin and nail tissue maintenance. Zinc deficiency is one of the most overlooked drivers of brittle nails and skin that takes longer to recover.

Marine Collagen Peptides
“I’ve used collagen for a year or so - [brand removed] Collagen Peptides in my coffee every morning. Can’t really say if it’s good for my skin or not, but worst case scenario, it’s just an extra 20 grams of protein in my diet!”Read the original
“Interesting that your doctors are so against. My internist has a "won't hurt you" stance. I am 65 and have noticed a huge decrease in the overall joint stiffness when I first get up in the morning. I take VitaProtein Marine Collagen.”Read the original
“Good quality marine collagen do have benefit. It won't drastically remove wrinkles and all but it has good anti ageing benifit. Like smooth supple skin, increase hair growth,strong nails,less joint pain . Myself consuming it since 1.5 year. I take continuous for 4 months and then give break for 2 months then start again. To see benefits need to consume it regularly for six months. Just negative thing t is it's high on pocket. Always choose proper quality collagen and only marine and bovine collagen works , no vegan collagen. I consume chosen dermatology brand collagen.”Read the original
“I’ve tried to read as many scientific articles on benefits of collagen supplements I could find on pubmed. My personal conclusion was that we need more extensive studies. So far, some say they work a bit, others say not much. Some also say it’s a placebo effect. I would say: Give it a try for atleast 6 months (I feel every skin and hair remedy needs to be tried for 6 months to gauge the benefits) and see it for yourself. Everybody is different. What didn’t work for many might work for you. Edit: just noticed you have asked for vegan alternatives. Those are a scam! Only bovine and marine collagen have potential benefits.”Read the original
“I've removed all skin care creams and serums and only take collagen, that way it doesn't seem that expensive”Read the original
Biotin
“Semi-related and possibly worth investigating: Zinc citrate has helped calm my skin down - less breakouts, redness and sebum/shine I’ve been taking it for 2 years. (15mcg)”Read the original
“So I usually advise against biotin. I had a similar bad experience with the supplement. I was taking it regularly and started to get a ton of body itches. Couldn’t figure out why. Tried changing soap, laundry detergent, etc. and then I read that biotin can cause whole body itching. Dropped it and since been fine.”Read the original
“Biotin makes me breakout too! I’ve been on the search for a general multivitamin but most of them include biotin so I feel like I’m out of luck. Anyone have any biotin-free recommendations?”Read the original
“I’m on my second container of last week. These helped my hair and nails a lot. Hair is growing in thicker (more baby hairs). Nails are the strongest I’ve ever had but also use nail strengthening polish too. Not all attributed to the gummies but I’m positive they’ve helped.”Read the original
“Omg I just realized I’ve been getting cystic acne recently and was wondering why …. I’ve been taking biotin gummies. Thank you for this comment.”Read the original
“I have had good luck with them but I have nutrient absorption issues so my body might just be happy with any vitamins etc.”Read the original

Honest answers
Questions you actually asked
Is this vegan?
No — the collagen is marine-sourced (wild-caught fish). If you want a fully plant-based beauty support, look at our Beauty + Collagen Strips (vegan-collagen-builder formulation).
Why marine collagen instead of bovine?
Marine collagen peptides have a smaller molecular weight than bovine, which research suggests improves absorption. They're also a more sustainable choice when sourced from wild-caught fish byproducts.
How quickly will I notice anything?
Beauty supplements are cumulative. Most testers describe nail changes first (4–6 weeks), then skin texture (6–10 weeks), then hair changes (8–12 weeks — hair grows slowly).
Is the biotin dose too high for me?
5,000 mcg is a standard hair-skin-nails dose and is considered safe. Note that high-dose biotin can interfere with thyroid blood tests — if you're getting bloodwork, pause for 72 hours beforehand and inform your physician.
When should I take it?
Pick a consistent time — morning is easiest to remember. Take with or without food.
What's in the gummy base?
Organic tapioca syrup, organic cane sugar, pectin, natural berry flavour, citric acid, natural fruit-derived colours. Contains gelatin? No — this gummy uses pectin (fish allergen comes from the collagen, not gelatin).
Can I take it with my ashwagandha?
Yes — they don't conflict. Many testers use the gummies as their beauty-stack daily and the ashwagandha for evening calm.
Is it safe during pregnancy or breastfeeding?
Talk to your physician before adding any new supplement during pregnancy or breastfeeding.
What if it doesn't work for me?
Email contact@withanly.com within 30 days of delivery and we'll refund the full amount — you don't need to send the bottles back.
How fast does it ship?
From our US warehouse, USPS Ground typically arrives in 2–4 business days within the contiguous US.
