Everything You Need To Know About Hair, Skin And Nail Supplements

You must have been living under an aesthetically unpleasing rock if you don’t know about hair, nail and skin vitamins. Since they took the world by storm in the mid ‘teens, they’ve changed the way we look at beauty and they’ve certainly changed the way we look at the humble supplement. This exciting concept of ‘beauty from the inside out’ has undergone a speedy evolution since it first bust onto the scene, so let’s take a closer look at all things skin-care supplements. 

What are beauty supplements?

Beauty supplements are founded upon the concept of supporting beauty from within. In the same way you take regular supplements to support your body’s health and wellbeing – such as magnesium for muscle health or vitamin C for immune health – beauty supplements can provide your body with the nutrients it needs for healthy hair, skin and nails. 

You can get supplements that target specific beauty concerns, such as skin elasticity, healthy hair,  or collagen formation, or ones that focus on certain skin-loving ingredients, like retinol. And, just like regular supplements, you can get beauty multivitamins for daily maintenance of general health and wellbeing with a twist - shiny, glowy beauty support.

How beauty vitamins work

The million dollar question is: do beauty supplements actually work? Just like regular supplements, beauty supplements support nutrient levels in the body when a person’s dietary intake might be inadequate. For example, retinol is part of the vitamin A family and is found in animal products such as meat, dairy and fish[1]. Consumption of retinol can help support skin health and structure. If you feel you need a little support in this area, then a beauty supplement could be a good way to support your daily vitamin A intake. 

One of the biggest ingredients in the beauty world is, of course, collagen. As we age, our natural collagen production slows down, but we can support our collagen levels through gelatin-rich foods like bone broth[2]. The body also needs vitamin C to support collagen production, which is found in dark leafy greens, berries, tomatoes, and citrus fruits[3]. In addition to enjoying bone broth with berries(!), you can consider a supplement that combines them together. 

While it would be great to get all the above beauty nutrients (and more!) from your diet alone, this can be a challenge for some people. This is one of the benefits of taking a regular beauty supplement, to help support nutritional levels in the body or simply ensure that you’ve got your hair, skin and nail nutrients covered – a bit like your beauty insurance policy. 

Can multivitamins improve skin?

Beauty multivitamins and supplements can support skin health when taken consistently. Consuming a beauty multi supports the health of skin by targeting the foundations with nutrients like vitamin A, vitamin C, niacinamide and zinc – from within. For a ‘double boost’ approach, you can take a daily beauty multi while continuing your topical skincare routine, to enjoy the beauty inside and out approach. 

What to look for in a beauty multivitamin

Beauty supplements are a highly trending area, with ingredients coming in and out of fashion at a rate that rivals a fashionista’s shoe collection. However, some old favorites are timeless pieces, like vitamin C, biotin, collagen, and hyaluronic acid. Generally considered to be amongst the best hair, nail and skin vitamins, keep an eye out for them when selecting your beauty multivitamin of choice.

You can also consider a multivitamin that looks at beauty more holistically. Swisse Beauty Multivitamin Beauty Complex doesn’t just contain nutrients that target skin health, it also contains ingredients that support your general health and wellbeing. For example, vitamin B3 supports vitality and helps relieve tiredness, and turmeric is traditionally used in Western Herbal Medicine to help relieve abdominal bloating. It also contains ashwagandha, traditionally used in Ayurvedic Medicine to help the body adapt to stress. We all know how stress, tiredness, and bloating can make you feel less than your dazzling self, so this unique formulation delivers a multi-level approach to beauty, by supporting you to both look and feel your best, inside and out.  

What vitamin is best for nails?

If you want healthy, strong nails, then biotin is your friend. Part of the B vitamins group (and also known under the aliases of B7 and vitamin H), biotin is necessary to assist healthy nail growth[4]. It is found in some meats, egg, seeds, nuts, and fish[5], and consuming biotin daily can make a positive difference to reducing brittle nails[6].  

What vitamin is best for skin and hair? 

Some vitamins which have been shown to have a positive impact on skin and hair health with daily supplementation are biotin[7][8] to support hair growth, vitamin C[9][10], and vitamin B3 (niacinamide) for skin health support[11]. Going beyond the realm of vitamins, you can also look for minerals like, zinc[12] to support skin health, and silicon to support hair and skin health, to help keep your locks glossy and shiny. 

How long does it take for hair, skin and nail vitamins to work?

Take hair, skin and nail vitamins for a minimum of three months on average, to start noticing a difference[13][14][15]. Importantly, you need to use them regularly and changes may vary from person to person. If you do want to give your beauty routine a boost, try making a beauty supplement part of your everyday skincare and wellness rituals, to help you look and feel your best from the inside out. 

Always read the label and follow the directions for use.
