The impact of dietary supplements on skin, hair, and nails

Written on February 15, 2025, by Pauline de Santarome

Dietary supplements are attracting growing interest among those seeking to improve the appearance of their skin, hair, and nails. These products provide essential nutrients to improve skin health, strengthen hair, and promote nail growth. However, dietary supplements should not replace a balanced diet. It is recommended that you consult a healthcare professional before starting any program, as the effectiveness of these products may vary depending on individual lifestyle habits.


Hair, nails, and skin

Nutritional requirements for healthy skin, hair, and nails


The health of our skin, hair, and nails is closely linked to our eating habits, as these tissues require an adequate supply of essential nutrients to remain healthy.


Essential nutrients


Vitamins play a crucial role in this process. For example, vitamin A promotes skin cell regeneration, while vitamin E protects cells from oxidative damage. B vitamins, such as biotin, are essential for strong hair and nails.

Minerals such as zinc and iron are also essential. Zinc contributes to skin healing and collagen production, while iron prevents hair loss. Omega-3 and omega-6 fatty acids are essential for maintaining hydrated and elastic skin, as well as promoting hair growth.


The impact of nutrition on physical appearance


A balanced diet has a direct impact on physical appearance. Nutritional deficiencies can manifest themselves in dull skin, brittle hair, and fragile nails. Conversely, a nutrient-rich diet promotes radiant skin, shiny hair, and strong nails.

It is therefore essential to incorporate a variety of foods into our diet, including:

  • Fruit,

  • Vegetables,

  • Whole grains,

  • Lean protein sources,

  • Healthy fats.


By ensuring that our nutritional needs are met, we actively contribute to maintaining the health and appearance of our skin, hair, and nails.


Are beauty supplements effective and do they work?


Beauty supplements often raise questions about their effectiveness. In reality, their impact varies from person to person. Some people report significant improvements, while others see more modest results, or even none at all. These products contain active ingredients that are touted for their benefits for the skin, hair, and nails. However, it is important to note that their effectiveness is not universal.


Dietary supplements should be considered as a supplement and not as a miracle solution. They support a healthy and balanced diet, but they cannot replace a healthy lifestyle.

Specific dietary supplements


Dietary supplements play an increasingly important role in our daily lives, meeting specific needs related to our lifestyle, diet, or goals.


Dietary supplements for the skin


Dietary supplements for the skin have become essential allies in maintaining healthy, radiant skin. Antioxidants, such as vitamin E, play a crucial role in fighting free radicals responsible for skin aging. Similarly, collagen helps maintain skin elasticity, promoting firmness.


Dietary supplements for hair


Dietary supplements play an essential role in maintaining healthy hair. Biotin, also known as vitamin B8, promotes hair growth and strengthens its structure. Iron, which is essential for proper oxygenation of the follicles, helps prevent hair loss. Amino acids, which are essential components of proteins, are fundamental for the formation of keratin, a key element in hair structure.


Among dietary supplements, Santarome's Sublime Hair Strength & Growth Tablets stand out. These supplements offer a complete solution for strengthening and boosting hair growth from within, providing a pleasant way to take care of your hair on a daily basis.


Dietary supplements for nails


Dietary supplements for nails are an effective solution for strengthening their health. By incorporating essential elements such as zinc, silica, and vitamin C, these supplements promote nail growth and strength.

Among dietary supplements, Keratin tablets and Sublimes Cheveux Force & Croissance plant extractsfrom Santarome stand out thanks to their ESSENTIA™ Complex, combining aromatherapy and gemmotherapy. By incorporating a trio of plants such as horsetail, rocket, and blueberry, this supplement helps improve the condition of nails and promote their growth.


Recommendations for use and precautions for dietary supplements


If you are about to start taking dietary supplements, it is important to follow the dosage and instructions indicated on the packaging. Never exceed the recommended dose, as this will not guarantee faster results and may even be harmful.

We strongly advise you to consult a healthcare professional before taking any supplements. They will be able to assess your needs, take into account any potential drug interactions, and provide you with personalized advice.



The impact of dietary supplements on skin, hair, and nails is undeniable, although results vary from person to person. They can help improve skin condition, promote hair growth, and strengthen nails. However, it is essential to emphasize that supplements cannot replace a balanced diet. The positive effects also depend on the quality of the products chosen.
