Everything You Need to Know About Vitamin C

Nature’s own energizers

Most energy products on the market are packed full of caffeine, sugar or excessive B vitamins. We challenged the status quo with a product that combines natural plant extracts for mental focus, along with sources of vitamin C to aid the immune system, the nervous system and to reduce tiredness and fatigue. Here’s what you need to know about our unique vitamin C products: C3 (available in Europe) and CX3 (available in the USA).

Clean label and natural ingredients

Both Puori C3 and CX3 are made from natural ingredients. In the body, vitamin C is in the form of ascorbic acid. Whilst there are limited differences in bio-availability of different vitamin C forms it is known that ascorbic acid can cause gastrointestinal problems in some people (1). For that reason, we chose vitamin C from natural sources, in the form of acerola, goji and rosehip, as well as mineral-bound ascorbates to make Puori C3 and CX3 suitable for those with sensitivities.

In addition, we use natural fillers such as inulin and starch rather than any synthetic fillers. We use natural stevia as a sweetener, with no sugar added, too.

Benefits from taking C3 / CX3

Immune function

Vitamin C contributes to the inner workings of the immune system (2). It is found in particularly high concentrations in immune cells suggesting an important role in protecting the body. Vitamin C deficiency leads to death of immune cells(3)

Additionally, the proven antioxidant properties of vitamin C are essential for immune cells to destroy invaders and is important for the regulation and movement of immune cells. In human trials, for individuals undergoing high levels of physical stress — for example, marathon runners or soldiers — vitamin C supplementation halved the incidence of colds. What this means for you is if you’re training regularly or putting your body under stress, then taking a vitamin C supplement may reduce the frequency of illness (4).

Oxidative stress

The main function of vitamin C in the body is as an antioxidant. Molecules known as free radicals are created by the body from normal body functions as well as from outside the body, for example exposure to pollution. An antioxidant such as vitamin C prevents free radicals from causing harm to our body’s tissues.  This is also particularly important after exercise. When we exercise, our tissues are damaged and become inflamed. A small amount of inflammation is beneficial and helps us grow stronger and recover faster, However, the balance is delicate – too much and recovery and progress may not be optimal (5)   

Nerve function

Nerves, like immune cells, have a high concentration of vitamin C. Vitamin C protects the cells from oxidative stress and is also needed for the nerves to ensure smooth signaling. Thus, vitamin C can help keep your nerve cells in your brain healthy and working correctly (6).

Reduction of tiredness and fatigue

Weakness and fatigue are common symptoms for vitamin C deficiency. A supplement with vitamin C can prevent deficiency reducing symptoms of fatigue.

Additionally, Ascorbic acid or vitamin C is one of the main regulators of iron balance. The role of vitamin C is to enhance the absorption of non-heme iron (7) from plant sources in the gastrointestinal tract. Iron contributes to haemoglobin formation which is the part of blood that transports oxygen throughout the body, thus playing an incredibly important role in providing adequate oxygen to your tissues and keeping you energized

This is why Puori C3 and CX3 are the perfect product to have to start the day, instead of coffee or tea. Alternatively, try them as a mid-morning or afternoon pick-me-up. Alternatively, consider using Puori C3/ CX3 as a pre-workout.
