Biotin and beta-carotene from 100% plant-based sources

How much biotin does your body need?

Your body’s cells cannot produce biotin (= vitamin B7) on their own, and the body can store this water-soluble vitamin only in limited amounts in the muscles, liver, and brain^.2 You must therefore obtain it regularly through your diet.

A healthy and varied diet is an important foundation for ensuring an adequate intake. Biotin is found in various foods in varying amounts. Sources include yeast, liver, eggs, legumes such as soybeans and lentils, as well as whole-grain products and oatmeal.^3,10,11

The German Nutrition Society (DGE)⁴ provides the following estimates for an adequate intake:

• For adults and pregnant women, 40 micrograms (µg) of biotin daily,
• 45 µg per day for breastfeeding women.

The European Union (EU) specifies 50 µg of biotin per day as the so-called nutrient reference value (NRV for short).⁵ In the manufacture of dietary supplements, the NRV serves as a guideline for the labeling of vitamins and minerals.

In certain life situations, dietary biotin intake can vary from person to person. Dietary supplements can help ensure an adequate intake of biotin.

Beta-Carotene and Vitamin A: What’s the Difference?

The term “vitamin A” refers to various fat-soluble compounds with vitamin A activity. They play a role in various normal bodily functions, such as vision, immune function, and cell differentiation. The most important form of vitamin A is retinol. Natural sources of preformed vitamin A are exclusively animal-based foods such as liver, fish, eggs, and dairy products.^6,7

In contrast, beta-carotene (β-carotene) is a precursor to vitamin A and is therefore also called provitamin A. It belongs to the group of carotenoids found in plants. However, only a small portion of these plant pigments serve as precursors to vitamin A—beta-carotene is the most important of these: Your body can convert it into vitamin A.^6,7

Beta-carotene, which is also fat-soluble, is found, for example, in carrots, apricots, pumpkin, and bell peppers, as well as in green leafy vegetables. For people who follow a vegetarian or vegan diet, foods rich in beta-carotene are an important source of vitamin A.⁷

rubyni^® Biotin Plus at a Glance

rubyni Biotin Plus is a dietary supplement made from natural and standardized plant extracts:

• The extract from sunflower seeds (Helianthus annuus) and cilantro leaves (Coriandrum sativum) naturally provides biotin (vitamin B7). Both raw materials come from certified organic cultivation in India. They are gently processed using lemon juice and coconut vinegar as natural solvents.
• Biotin is combined with beta-carotene, a carotenoid that gives carrots their characteristic color. It is a natural precursor to vitamin A. For our product, we use a gently extracted extract from carrots ( Daucus carota subsp. sativus ), which is free of fructose.

• rubyni Biotin Plus is rounded out with a pure extract of grape seeds (Vitis vinifera) and olives (Olea europaea). It provides two phytochemicals from the polyphenol family: OPC (oligomeric proanthocyanidins) and hydroxytyrosol. The raw materials come from France and are standardized for their polyphenol content.

Biotin – Not Just for Skin and Hair

Biotin (vitamin B7) is also known as vitamin H. This refers to its importance for hair and skin.¹⁰ Biotin helps maintain normal hair and skin—as well as normal mucous membranes.¹

In addition, biotin performs other functions in your body: It contributes to normal energy metabolism, as well as to the normal metabolism of macronutrients. These include carbohydrates (sugars), proteins, and fats. Biotin also plays a role in the normal functioning of the nervous system and normal psychological function.^1,11
