The best natural vitamin C with acerola and rosehip

Vitamin C is the most important vitamin to protect health and boost the immune system.

Unfortunately, not all forms of vitamin C are equally efficient. Vitamin C based on ascorbic acid, which many vitamin C dietary supplements are, is significantly less effective.

Natural vitamin C with acerola and rosehip is the new dietary supplement from our 4Endurance Pro product line. It is a completely natural source of vitamin C, based on rosehip and acerola fruits.

The result?

High absorption and long-lasting effect in your body. And that's the best way to protect your health and boost your immune system.

Natural vitamin C 

Natural vitamin C dietary supplements contain different sources of vitamin C. Broccoli, pepper, Brussels sprouts, various types of exotic fruit ...

Our Natural vitamin C contains acerola and rosehip. This enables different types of release and is gentle to the stomach. Especially rosehip has been used for centuries and its effects and benefits have been proven by tradition.

Acerola and rosehip are two excellent natural sources of vitamin C.


Acerola is a fruit also known as the Caribbean cherry. Due to its amazing properties it is considered a superfood. It packs approximately 20 times more vitamin C than lemon, and due to the flavonoids and carotenoids it contains, its absorption is much better than broccoli or cauliflower.

The flavonoids and carotenoids in acerola are also a strong natural antioxidant that protect your cells from oxidative stress, free radicals, and harmful influences of the environment. They also reduce the levels of the stress hormone cortisol in your body.

Acerola - natural source of vitamin CAcerola is a great natural source of vitamin C.

The irony is that the riper the fruit (bright red), the less vitamin C it contains, while consuming an unripe fruit is not recommended. Consuming acerola in the form of a dietary supplement is the practical solution that provides all the benefits of the fruit without potential problems.

Acerola is a superfood with 20x more vitamin C than lemon.


Rosehip is one of the oldest ornamental plants. It grows in many gardens and is part of the traditional medicine. Rosehip tea has been used as medicine way before we were familiar with the concept of vitamin C and its benefits in alleviating cold, reducing fatigue, and boosting the immune system.

Rosehip is a rich source of vitamin C and a strong antioxidant. It contains bioflavonoids, ellagic acid, and phenols, which protect your cells from oxidative stress and the negative effects of the environment and boost your immune system. 

The best natural source of vitamin CRosehip has been used for centuries to boost the immune system.

Rosehip and vitamin C won't prevent or cure cold by themselves, but they can considerably improve the way you feel during illness, alleviate the symptoms, and support your immune system.

Rosehip is a powerful antioxidant and a very rich natural source of vitamin C.

Why supplement vitamin C?

During exercise your body is under severe stress, which weakens your immune system and you become more susceptible to infection.

An athlete needs a lot more vitamins and minerals than people who don't practice sports.

It is especially important to increase your vitamin C intake during temperature fluctuations and when your intake of fresh fruit and vegetables is reduced.

What's the difference between natural vitamin C and synthetic vitamin C?

Synthetic vitamin C, the so-called ascorbic acid, is significantly less effective than natural vitamin C.

Ascorbic acid created in a lab is in fact only an ingredient of vitamin C. We could go as far as to say that it is an imperfect form, as it doesn't contain the bioflavonoids and glycosides that are present in natural vitamin C.

Bioflavonoids function as a ionophore. In simple words, they allow vitamin C to be absorbed.

Furthermore, ascorbic acid competes in the body for absorption, which may have unwanted side effects.

  • Calcium depletion (because calcium tries to neutralize the excess acid in your body).
  • Digestive issues.
  • Stomach acid and irritated gastric mucosa (ascorbic acid is 10x more acidic than natural vitamin C).

Ascorbic acid is a preservative that destroys pathogenic microbes. Unfortunately, it can't tell the difference between good and bad bacteria, which can ruin your natural intestinal flora.

What's the recommended dose of vitamin C?

You can find many theories online on what the optimal dose of vitamin C is. In our opinion, in winter time, during increased effort (athletic or cognitive), stress, and weather changes, the optimal dose is 500 mg. Why?

Perhaps you heard that you can sustain sufficient levels of vitamin C with an intake of 75 mg of vitamin C per day, be it from food or supplements.

But this doesn't take into consideration different absorption levels of individual sources of vitamin C and the 3-4x greater needs of micronutrients of athletes during stress.

That's why 500 mg of vitamin C per day is the optimal and safest dose for healthy athletes who want to keep their immune system in top shape.

What are the symptoms of vitamin C deficiency?

Let's remember the sailors who during their long journeys without a source of vitamin C developed scurvy within a few months. 

Vitamin C deficiency, and consequently collagen deficiency, weakened their connective, bone, and vascular tissues. They were affected by disease, inflammations, anemia, and physical injuries. All until James Lind (and not James Cook, as it is falsely believed) provided his crew with citrus fruit.

Symptoms of vitamin C deficiencyVitamin C deficiency is devastating to your immune system.

Since then, vitamin C is considered as the vitamin of health and a strong immune system. It is involved in numerous body functions, including collagen production, iron absorption, correct function of the immune system, wound healing, and preservation of cartilage, bones, and teeth.

Can I intake too much vitamin C?

High doses of vitamin C, especially doses of 2000 mg or more, don't make sense, as your body won't be able to absorb such a high dose of vitamin C, and it will be quickly excreted from the system.

Even worse, excessive doses of vitamin C can over time lead to the development of kidney stones and cause false elevated values of glucose in your blood.

Ingesting more than 3000 mg of vitamin C per day can lead to stomach issues and indisposition, and vitamin C may develop a prooxidant effect (reversing its role), which harms your tissues instead of protecting them from free radicals. 


Natural vitamin C with acerola and rosehip is an excellent source of vitamin C with high absorption and long-lasting effect.

Temperature changes, stress, and increased physical exertion negatively impact your body.

A strong immune system is essential, especially for athletes, as their immune system is weakened during exercise, which makes you the most susceptible to infection.

Natural vitamin C is the best form of vitamin C, which allows you to absorb sufficient quantities of this vital vitamin. Trust the natural form of vitamin C!
