How much vitamin C does your body need?
Vitamin C is found in fruits and vegetables, among other foods. Your body cannot produce this nutrient on its own. Therefore, you need to regularly consume sufficient amounts through your diet.2 But what exactly does that mean?
The German Nutrition Society (DGE) recommends a daily intake of 95 mg of vitamin C for women. For men, the recommendation is 110 mg per day. If you are pregnant, breastfeeding, or smoking, your vitamin C needs may be higher. Your needs may also vary during periods of intense physical activity or under certain life circumstances.3,4,5
The European Union (EU) specifies a daily requirement of 80 mg of vitamin C for both genders. This is known as the Nutrient Reference Value (NRV for short). This serves as a guideline in the manufacture of dietary supplements when it comes to the dosage of vitamins and minerals.6
Which fruits are particularly high in vitamin C?
What comes to mind when you hear the term “vitamin C”? Most people immediately think of a lemon or an orange. But there are fruits that contain far more vitamin C. These include the acerola cherry and amla, the Indian gooseberry.
Acerola is native to Brazil and is one of the fruits richest in vitamin C. Depending on its ripeness and how it’s processed, 100 g of the fruit can contain up to 1,700 mg of vitamin C. Amla also provides several hundred milligrams of this nutrient per 100 g of fruit. By comparison, a lemon contains about 50 mg of vitamin C per 100 g of fruit.7,8,9
rubyni® Vitamin C—what’s in our capsules
One rubyni Vitamin C capsule contains 164 mg of acerola fruit powder and 359 mg of amla fruit extract, which together provide 212 mg of vitamin C. This corresponds to 266% of the daily value for vitamin C based on the Nutrient Reference Value (NRV*).
Two capsules provide 328 mg of acerola fruit powder and 718 mg of amla fruit extract and contain 425 mg of vitamin C, which is 531% of the NRV*.

rubyni® Vitamin C at a Glance
rubyni Vitamin C is a dietary supplement that contains two different plant-based sources of vitamin C: organic amla fruit extract (from Emblica officinalis) and organic acerola fruit powder (from Malpighia glabra).
We use select fruits from Brazil to make our organic acerola fruit powder. The amla fruit is also known as the Indian gooseberry. Our fruits are grown in the Ooty highlands, among other places—this region in India is known for amla cultivation.
The vitamin C content is standardized during the processing of the raw materials to ensure a consistent product composition.
Good to know:
Vitamin C: A Nutrient with Multiple Functions in the Body
You’ve surely heard that vitamin C supports the normal function of the immune system. But this nutrient is also involved in other processes in the body. Among other things, it contributes to normal collagen formation for the normal function of blood vessels, bones, cartilage, gums, teeth, and skin. Collagen is the most abundant protein in the human body and, among other things, an important component of connective tissue.1,10
In addition, vitamin C contributes to normal energy metabolism and helps reduce tiredness and fatigue.
Do you follow a vegetarian or vegan diet? If so, it may be a good idea to combine iron-rich meals with vitamin C: Vitamin C increases the absorption of iron from food, especially from plant-based foods such as legumes, oatmeal, or pumpkin seeds.1,4,11
What does vitamin C have to do with oxidative stress?
Vitamin C helps protect cells from oxidative stress. Oxidative stress can be caused by so-called free radicals. These are highly reactive molecules that occur naturally during metabolism or as a result of external factors such as radiation exposure, and can damage cellular structures.1,12,13
Vitamin C is also important for your nerves: It contributes to the normal functioning of the nervous system and to normal psychological function. It also supports the normal production of neurotransmitters. Neurotransmitters are substances that, among other things, transmit signals from one nerve cell to the next.1,14
Animals, People, and Vitamin C: Did You Know That?
Did you know that most animals can simply produce their own vitamin C? Dogs, cats, and many species of birds produce it in their bodies every day—without any fruit or dietary supplements.
Humans, however, are among the few exceptions. Just like monkeys and guinea pigs, we have lost the ability to produce vitamin C on our own over the course of evolution. That is why we must obtain it regularly through our diet.15
Vitamin C (ascorbic acid) occurs naturally in numerous fruits and vegetables, where it is incorporated into the natural food matrix along with other plant-derived compounds. For dietary supplements, vitamin C can either be extracted from such natural plant sources or produced industrially. In both cases, it is chemically the same ascorbic acid—the difference lies in its origin and its integration into the natural plant matrix.
What role does vitamin C play in the body (health claims)?
Vitamin C plays a role in numerous normal bodily functions:
Vitamin C
- contributes to the normal functioning of the immune system during and after intense physical activity*
- contributes to normal collagen formation
- for a normal function of the blood vessels
- for normal bone function
- for normal cartilage function
- for normal function of the gums
- for normal skin function
- for normal function of the teeth
- contributes to normal energy metabolism
- contributes to the normal function of the nervous system
- Contributes to normal mental function
- contributes to the normal function of the immune system
- contributes to the protection of cells from oxidative stress
- contributes to the reduction of tiredness and fatigue
- contributes to the regeneration of the reduced form of vitamin E
- increases iron absorption
*Applies when an additional 200 mg of vitamin C is consumed daily.

Is Rubyni Vitamin C vegan, gluten-free, and lactose-free?
Yes, rubyni Vitamin C consists of 100% vegan ingredients enclosed in a plant-based capsule shell (made from hydroxypropyl methylcellulose): The vitamin C comes from the fruits of the acerola and amla. All ingredients are vegan, lactose-free, and gluten-free.
What are the functions of vitamin C in the body?
Vitamin C contributes to many key bodily functions: It supports the normal functioning of the immune system, contributes to normal energy metabolism, and helps protect cells from oxidative stress. It also plays a role in normal collagen formation. This is important for the skin, bones, cartilage, gums, teeth, and blood vessels.1

EXPERIENCES THAT BUILD TRUST
Tobias Angerer
Cross-country skier
As a former professional athlete and health-conscious person, my physical performance and well-being are extremely important to me. That's why I take rubyni® with elderberries - it's now part of my daily routine. I am convinced of the positive effects of elderberries on my immune system, my energy levels and my fitness, especially during regeneration after periods of exertion.
Andrea Sokol
Phytotherapist | Nutrition and health consultant
I work as a nutrition and health consultant and am a trained phytotherapist. Transparency, sustainability and quality are very important to me. And I have to say that rubyni® has completely won me over as a brand. The capsules contain only extremely high-quality and natural ingredients whose effectiveness has been proven by studies and which provide the body with important nutrients. I have published several videos about my personal rubyni® journey on my YouTube channel Ohlala & Solala. There I tell you even more about what makes this dietary supplement so special from my point of view.
Hanna Kebinger
Biathlete
As a biathlete, I have to be fit and able to perform at the drop of a hat. I had big problems with that in the past. My body was repeatedly weakened and I had to put up with many setbacks. When I was looking for a solution to support my immune system in the long term, my naturopath introduced me to elderberries as a superfood, among other things. I now take rubyni® with elderberries every day. The capsules are also super handy when I'm on the World Cup circuit. Rubyni® is a valuable aid for me during stressful competition phases and my immune system is finally back on top form.
