Hair and Nails
Strong hair and healthy nails are a visible sign of vitality. But their quality comes from within—and depends largely on a good supply of vitamins, minerals, and amino acids. Although hair and nails are primarily visible on the outside, they are formed inside the body—and that’s exactly where their strength, shine, and resilience are determined.
Thin hair, brittle nails, or slow growth can be signs that the body is lacking important nutrients.
But which vitamins and minerals play a role here? And how can you specifically support your hair and nails? Here, you’ll learn which essential nutrients strengthen your hair and nails from the inside out, how you can obtain them through your diet, and which natural supplements can effectively round out your nutrient intake.
Promote Healthy Hair Growth
Healthy, strong hair requires more than just external care. Above all, good blood circulation in the scalp and an adequate supply of nutrients are crucial. This is because new cells are constantly forming in the hair follicles—the hair’s tiny “growth centers.” For this process to run smoothly, they need a constant supply of oxygen, vitamins, and minerals. However, if this supply is disrupted—for example, by stress, nutrient deficiencies, or reduced blood flow—the hair roots react sensitively: growth slows down, the hair appears thinner, or it loses its strength.
Metabolic processes (e.g., energy, amino acid, and hormone metabolism) also play a central role. They ensure that nutrients are absorbed, transported, and utilized by the hair follicles. If these metabolic processes are overburdened or weakened, important nutrients often fail to reach the hair papillae (the hair’s nutrient supply centers) reliably.
That's why effective hair care starts from within. If you boost your metabolism and provide your hair roots and hair papillae with all the essential nutrients, you can enjoy shiny, strong hair in the long run.
The Best Vitamins for Healthy Hair
Our hair consists mainly of keratin—a structural protein that acts like a fine framework, making each hair strand strong and elastic. Your body needs important nutrients to produce keratin. These include:
- B vitamins such as vitamin B6 are needed for the formation of cysteine (a building block of keratin), while vitamin B7 (biotin) is directly involved in keratin formation and supports the maintenance of healthy hair.
- Zinc helps maintain healthy hair, supports cell division, and ensures that new hair cells can form.
- Copper plays a role in hair pigmentation, which is important for natural hair color.
- Iron is crucial for oxygen transport in the blood and thus also supplies the hair follicles.
- Collagen and proteins in general provide the building blocks for strong hair strands. They strengthen the structure and give the hair support.
A comprehensive basic supply of vitamins and minerals is provided, for example, by the Nutrient Package Basic with Pro Mineral Complete and Pro Multivitamin Complete, while Pro Krypto Balance is recommended when there is an increased need for B vitamins, zinc, manganese, and chromium.
Healthy nails aren’t just a sign of beauty. Rather, they’re like a small mirror reflecting your overall health. If they become brittle, soft, or have fine ridges running through them, this often indicates an imbalance in the body. That’s because stress, hormonal fluctuations, or a nutrient-poor diet can weaken the so-called nail matrix—the area under the cuticle where your nails begin to grow.
For your nails to grow strong, smooth, and resilient, your body needs a solid foundation.Keratin, the main component of your nails, can only be produced optimally when sufficient vitamins, minerals, and protein building blocks are available. Equally important are good blood circulation and an active metabolism, so that all nutrients reach the places where they’re needed.
So if you’re constantly struggling with brittle or slow-growing nails, external care alone is rarely enough. True strengthening begins from within—where new nail cells are formed and grow. In the next section, we’ll take a closer look at which nutrients are particularly beneficial for your nails.
The Right Nutrients and Vitamins for Strong Fingernails
Healthy nails need a solid foundation. This is what determines how well your nail matrix is nourished and how strong new nail cells grow. The following micronutrients play a key role in this process:
- Vitamin B6 supports the formation of cysteine—an important building block for the keratin in our fingernails. Vitamin B7 (biotin) also contributes to keratin formation and supports the maintenance of normal nails.
- Zinc contributes to the maintenance of healthy nails and helps protect them from oxidative stress.
- Copper supports fingernail health by contributing to both the maintenance of connective tissue and skin pigmentation.
- Silicon is a natural component of nails and can therefore strengthen their structure.
- Iron supports normal oxygen transport in the body, including to the nail root, also known as the nail matrix.
- Collagen contributes to the strength and elasticity of the nails and can positively influence their growth.
- Amino acids, as the building blocks of keratin and collagen, are essential for building healthy, strong nails.
For an optimal supply of all the important minerals and vitamins your fingernails need, the Nutrient Package Basic—which includes Pro Mineral Complete and Pro Multivitamin Complete—is ideal.
