"Nutrafol is a supplement with actual multi-mechanism evidence, not just a single ingredient like biotin. It contains hydrolyzed marine collagen as its core ingredient, plus saw palmetto, which is a 5-alpha reductase inhibitor that addresses androgenetic alopecia, ashwagandha to help with stress-related hair loss, and anti-inflammatory ingredients like curcumin. It addresses different root causes and can be genuinely complementary to your hair care routine, unlike taking a single ingredient biotin gummy at thousands of times the daily dose."

Dermatologist Gets Real About Hair Loss | Do Supplements Actually Work?

"Nutrafol has hydrolyzed Marine collagen, one of the key ingredients. Studies have shown that Marine collagen supplements can increase the growth of terminal and vellus hairs, so thick hairs and the baby hairs. It can also increase the diameter of terminal and vellus hairs as well as decrease hair loss. It also has Apple polyphenols as well as ashwagandha, shatavari, saw palmetto, cumin, and a whole host of different vitamins and minerals including A, C, D and E, B vitamins including biotin, iodine, selenium, and zinc. You have to take four pills a day."

"Both Nutrafol and Viviscal have clinical studies behind them. They both have hydrolyzed marine collagen as their core ingredient. I like Nutrafol for people who are also dealing with stress-related hair loss cuz they have ingredients to support that as well. I would say that these are the two clinical-grade hair supplements that I recommend most often to my patients."

"Let's take my daily dose of Nutrafol. I love it. Honestly, the majority of supplements out there are just complete BS and there's really not a lot of science backing them. Nutrafol is the exception. I have seen so many different doctors and specialists recommend Nutrafol. The before and afters are incredible. I took Nutrafol and saw so many good benefits. I really need to start taking it again."

"There are a few vitamin supplements that I recommend to my patients if they ask me for recommendations that can potentially support their hair regrowth journey and that's Nutrafol and the Viviscal. Both of those do contain biotin but it's not the biotin that's actually helping. It's their proprietary blend of active ingredients that is supporting that hair regrowth."

"Depending on the type of hair loss you have you may only need to take it for a certain amount of time, but for more progressive hair loss like androgenetic hair loss it definitely is more of a long-term treatment so it can get pricey. But yeah, of all the hair loss supplements out there, Nutrafol is definitely one of the few brands I recommend."

Dermatologist Compares Nutrafol & Viviscal

"Nutrafol launched in 2016 and has gained popularity much more quickly over the past few years amongst consumers and dermatologists alike. Nutrafol contains 21 ingredients that make up their trademark Cynatine complex, which is essentially a blend of phytoactive, plant-derived ingredients that have anti-inflammatory, antioxidant, and stress-adaptogens as well as DHT-inhibiting effects. Some of the ingredients you can find within their complex include curcumin, the main phytoactive from turmeric, and ashwagandha, to name a few. Nutrafol also contains amino acids, marine collagen, hyaluronic acid, and a few other vitamins and minerals that all make up those 21 ingredients. Nutrafol can help those who are undergoing a lot of stress-related hair loss and has been mostly studied in the context of improving androgenetic hair thinning, but because of all those antioxidants and adaptogens it could possibly improve stress-related hair loss."

"I do not like any supplements with biotin so I try to take supplements that do not have biotin. You can even try prenatal vitamins in addition to, for example, the vegan Nutrafol, which is my preferred type of Nutrafol if you're going to go down that route."

"I switched to Nutrafol because it not only had those basic vitamins that we need, but they also offered anti-inflammatory benefits that help with the stress hormones being released throughout your body. I originally went for the original Nutrafol and then switched to the vegan one because the pills are smaller. I have been consistent with Nutrafol. I had a pill box where I actually put them in, it's like a ritual every Sunday, and I just have been taking it twice a day."

Hair Loss Treatments That Actually Work for Women & Men! | Dr. Shereene Idriss

"It's a natural solution to promote hair growth that patients swear by. The company itself has shown results through their own studies, but don't underestimate placebo in helping yourself, especially when it comes to hair. Nutrafol helps with hormonal imbalance, inflammation, oxidative stress, and nutritional deficiencies because it's a multivitamin. If you're going to take Nutrafol, be careful I'm taking a multivitamin as well because you don't want to overdose on vitamin A or vitamin D. The trick to this is being very consistent with it over six months, which sucks because it's expensive. That is the reality, and you're not going to grow hair elsewhere on your body that doesn't happen."

"Nutrafol is definitely one you've seen more for, but because of the inclusion of an ingredient called saw palmetto in their Syneren complex, this is generally thought to be unsafe during both pregnancy and breastfeeding. The risk in pregnancy is much stronger because it inhibits DHT and that would inhibit hormones and fetal development. Breastfeeding, the risk of absorption and passing on is probably a lot less, but it's still probably something you should avoid. Nutrafol does have more studies in general, but because of the ingredient profile, it comes out as less ideal in the postpartum period."

"Years ago I did a deep dive on the ingredients behind Nutrafol, whether they work. At the start of 2025, the gastroenterology physician community is voicing concern for Nutrafol. There was a case report at the end of 2024 of a patient who developed extreme liver damage on Nutrafol, and her liver healed once she stopped it. Her doctor pointed out that Nutrafol has multiple ingredients that could be damaging to the liver. Maybe one or two of those ingredients in an otherwise healthy person at a small dose would be fine, but when you have multiple ingredients, multiple hits to the liver, in a pretty much otherwise healthy person, it tips things over the edge and can cause liver damage. The authors who took care of this patient and wrote up her case suggested that patients taking this dietary supplement should undergo monitoring of liver function to make sure they're not having some kind of adverse event. But Nutrafol isn't going to tell you that. Nutrafol isn't going to say this supplement may cause liver injury. They're not required to disclose that to you. Nutrafol is going to appear, for all intents and purposes, to be safe, to be natural, great for hair growth, even though the evidence on that is super weak. There's no real established efficacy data."

"The research for them in the absence of a true nutrient deficiency is pretty weak, and whether or not they're actually going to make a difference is really hard to say. The research just doesn't support that. I think a lot of people recommend supplements like Nutrafol because honestly I think a lot of it boils down to wanting to be able to offer something, but it's a slippery slope when there is such limited research behind these formulations. The other thing I will strongly caution against is biotin supplementation, which is often in these hair growth supplements. Biotin supplementation in the absence of a true biotin deficiency, which by the way is very rare, biotin supplements have not been shown to actually help with hair growth. The problem with biotin supplements is that they can interfere with the accuracy of blood work, and this can become very problematic for you."

"I've used Nutrafol for a long time, I used it for years, and I didn't see any difference with me whatsoever. The reason is because my problem isn't the nutrients. I'm a holistic nutrition and health coach, my nutrients are pretty spot on. The problem with me is the circulation, so if I already have a diet that is spot on and I already have adequate amounts of collagen, adequate amounts of biotin, adequate amounts of iron, I could do all of that and still not have hair growth because I don't have the circulation that's bringing it there. I could be taking these pills every single day for hair growth, but I'm already getting that with my own vitamin line, I'm already getting folate and iron and all of the stuff that I need to grow hair through my own nutrition line, so for me it was like, why am I taking this extra vitamin? That's not my problem. My problem isn't that I'm lacking vitamins, my problem is that I'm 55, genetically I don't have a long growth phase."

"Deficiencies are another very common cause of hair thinning. Now you can go to a doctor and get your labs drawn to see what you may be deficient in, or you can consider an all-in-one hair thinning supplement, one like Nutrafol. Nutrafol is an all-in-one hair supplement. They make it for men, they make it for premenopausal women, post-menopausal women, and vegan women as well. I regularly take Nutrafol to help with my hair."
