Quick answer

For skin, hair and nails, zinc, selenium and vitamin C are central: zinc contributes to the maintenance of normal hair, nails and skin, selenium to normal hair and nails, vitamin C to normal collagen formation for the skin. Good products combine these recognised nutrients sensibly with one another.

Skin, hair and nails are often regarded as a mirror of the body's overall supply. If you want to support them from within, you should know which nutrients play a recognised role for their maintenance. With the goal of skin, hair & nails, it is therefore about targeted micronutrients – above all certain trace elements and vitamins with clear EU health claims. This guide classifies the most important substances and shows suitable Scheunengut products.

An honest note right at the start: no preparation conjures up firmer skin or stronger hair overnight. Skin, hair and nails grow slowly and reflect the supply over weeks and months. The following recommendations therefore rely on nutrients with recognised EU health claims for their maintenance and openly classify what role plant-based ingredients and enzymes play in this.

What matters for the goal of skin, hair & nails

For the maintenance of skin, hair and nails, zinc and selenium in particular are backed by authorised EU health claims. Thus: Zinc contributes to the maintenance of normal hair, Zinc contributes to the maintenance of normal nails and Zinc contributes to the maintenance of normal skin. For hair and nails, selenium is also relevant: Selenium contributes to the maintenance of normal hair and Selenium contributes to the maintenance of normal nails.

Another key nutrient for the skin is vitamin C, because it is involved in collagen formation: Vitamin C contributes to normal collagen formation for the normal function of skin. In addition, antioxidants protect the cells in everyday life: Vitamin C contributes to the protection of cells from oxidative stress and Zinc contributes to the protection of cells from oxidative stress.

Besides these vitamins and trace elements, many products rely on plant-based companions or enzymes such as bromelain and papain, which are traditionally used. For such plant and enzyme ingredients there are no specific EU health claims. The nutritionally justified role for skin, hair and nails is therefore taken on in the products by the added micronutrients such as zinc, selenium or vitamin C.

Our product recommendations

Extensive lungwort complex optimised with vitamin C

This 14-in-1 complex combines traditionally used lungwort with vitamin C. For the skin, the vitamin C base is decisive, because Vitamin C contributes to normal collagen formation for the normal function of skin and Vitamin C contributes to the protection of cells from oxidative stress. A broadly based herbal complex with a clear skin reference through the contained vitamin C. View the extensive lungwort complex with vitamin C

Gastro-resistant bromelain complex with papain and rutin

This complex combines the traditionally used enzymes bromelain and papain with rutin in gastro-resistant form. Enzymes and secondary plant substances such as rutin have long been valued; there are no specific EU health claims for skin, hair and nails for them. If you want to supplement your nutrient concept with an enzyme-based complex, you will find a well-thought-out formulation here. View gastro-resistant bromelain complex

Foundations first

Beautiful skin, strong hair and firm nails do not arise from capsules alone. The basis is a balanced, nutrient-rich diet with sufficient protein, healthy fats, fruit and vegetables, plus enough fluid, good sleep and a moderate approach to sun and stress. If you eat a varied diet, you already take in many of the mentioned nutrients through food. Food supplements are then sensible when individual nutrients are difficult to cover, in special phases of life or when you want to supplement zinc, selenium or vitamin C in a targeted way. They are a supplement, not a substitute for healthy habits. Pay attention to the recommended intake amount and avoid overdosing the same nutrient through several products.

Also not to be underestimated are factors that act on skin, hair and nails from the outside. Mild care, sufficient sun protection, a moderate approach to heat and chemicals when styling, as well as enough sleep pay off visibly on the appearance. Stress and smoking also leave traces over time. A targeted nutrient supply through zinc, selenium or vitamin C supports the maintenance of normal structures from within, but cannot make up for these external influences. You therefore benefit most from a combination of a nutrient-rich diet, a gentle care routine and a healthy lifestyle. Food supplementation fits in here as one building block that starts in a targeted way where the supply through the diet is difficult, and that unfolds its contribution over a longer period.

How to find the right product

When choosing, orient yourself by the micronutrients that are backed by authorised statements for skin, hair and nails: zinc, selenium and vitamin C. A sensible product clearly states these nutrients and does not put them behind plant-based ingredients. If your focus is rather on hair and nails, a selenium-containing product is the obvious choice; if the skin is in the foreground, vitamin C plays a supporting role because of its role in collagen formation.

Secondly, take your diet into account. Zinc is found in whole grains, legumes, seeds and animal foods, selenium in nuts and fish, vitamin C in fresh fruit and vegetables. If you eat a varied diet, you already cover a lot; supplementation is sensible where you suspect gaps. In this way you avoid taking many products in parallel and start in a targeted way at one point.

Thirdly, think of patience and regularity. Since skin, hair and nails renew themselves only slowly, a targeted nutrient supply unfolds its supporting contribution over a longer period. Therefore choose a product that you can integrate well into your everyday life, and keep an eye on the overall intake of the individual nutrients through the labels.

Frequently Asked Questions (FAQ)

Which nutrients are most important for skin, hair and nails?

Backed by authorised EU health claims are above all zinc, selenium and vitamin C. Zinc contributes to the maintenance of normal hair, nails and skin, selenium to the maintenance of normal hair and nails, and vitamin C to normal collagen formation for the normal function of skin.

How quickly do you see results?

Skin, hair and nails renew themselves slowly over weeks and months. A targeted nutrient supply therefore acts supportively over a longer period. Patience and regularity are more important than short-term expectations. The mentioned claims describe the maintenance of normal structures.

What does vitamin C do for the skin?

Vitamin C is involved in the body's own collagen formation. It applies: vitamin C contributes to normal collagen formation for the normal function of skin. In addition, vitamin C contributes to the protection of cells from oxidative stress.

Do enzymes such as bromelain act on the skin?

Bromelain and papain are traditionally used enzymes for which there are no specific EU health claims for skin, hair or nails. The justified role for this goal is taken on in products by the added micronutrients such as zinc, selenium or vitamin C.

Can I combine several products?

Yes, as long as you observe the recommended daily dose of the individual nutrients. If several products contain, for example, zinc, you should add up the amounts to avoid overdosing. A look at the labels helps to keep track.

Note: In the case of existing illnesses, during pregnancy and breastfeeding or when taking medication, please speak with your doctor before use.
