Vitamin C plus bioflavonoids to meet your daily basic needs: This supplement is ideal for daily use and can be taken throughout the day to ensure a continuous supply. It supports your immune system and protects your cells from free radicals (oxidative stress). The buffered, stomach-friendly vitamin C is combined with the valuable bioflavonoids quercetin, rutin, and hesperidin—inspired by nature, since vitamin C in fruits and vegetables is always found together with bioflavonoids.

NATURAL DIETARY SUPPLEMENTS FOR YOUR HEALTH

What is vitamin C good for?

Vitamin C, also known as ascorbic acid, is an essential vitamin that the body cannot produce on its own. We therefore rely on obtaining it through our diet.
Vitamin C is important for many bodily functions, such as the immune system. It supports both the innate and adaptive immune systems. White blood cells, or leukocytes, contain particularly high levels of vitamin C. As a result, the body’s need for vitamin C increases during an infection. This makes TISSO’s vitamin C ideal when you notice an infection coming on.

Vitamin C can do so much more. This all-around powerhouse performs the following functions in our bodies:

As an antioxidant, it protects our cells from oxidative stress.
It supports collagen production and is therefore essential for healthy skin, bones, cartilage, teeth, and blood vessels.
Vitamin C is beneficial for the nervous system and for mental health.
It also promotes iron absorption and helps reduce tiredness and fatigue.

Contains valuable bioflavonoids: quercetin, rutin, and hesperidin

Bioflavonoids belong to the group of polyphenols. They are powerful antioxidants found in plants that protect them from UV rays, insects, and other pathogens. Bioflavonoids also offer many health benefits for us humans. Studies have shown that they possess antiviral and antibacterial properties. As a result, they also support our immune system—ideally when taken together with vitamin C.

High-Dose Vitamin C: When Is It Too Much?

Some supplements on the market provide up to 1 g of high-dose vitamin C in a single capsule. However, when 1 g (1,000 mg) is taken orally, only about 65–75 percent of the vitamin C is absorbed. Vitamin C that is not absorbed is broken down by the colon flora primarily into carbon dioxide (CO₂) and organic acids. For this reason, taking high doses of vitamin C can lead to gastrointestinal symptoms such as abdominal pain and diarrhea. In addition, excess vitamin C that the body has absorbed but does not need is excreted in the urine.

To ensure you get enough vitamin C throughout the day without overburdening your kidneys, TISSO’s vitamin C provides about 250 mg of vitamin C per capsule. To maintain plasma levels throughout the day, we recommend taking two capsules at least 5 hours apart.

A Comparison of Pro Vitamin C and Pro Vitamin C Ultra

We have two vitamin C products in our lineup. Both products contain buffered vitamin C as well as a high-quality bioflavonoid complex to provide you with additional phytonutrients and enhance the bioavailability of the vitamin C.

Pro Vitamin C It's ideal for meeting your daily basic vitamin C needs. Pro Vitamin C Ultra On the other hand, thanks to its special liposomal formulation, it is the ideal choice when vitamin C requirements are high or when vitamin C levels need to rise quickly and be maintained over an extended period. Such increased needs often arise during infections, intense physical activity, in older adults, and during pregnancy and breastfeeding.
