Who doesn't know caffeine?

Caffeine is extremely popular around the world. If you want to add caffeine to your supplementation - we have an excellent offer for you! Caffeine with the addition of grapefruit extract in a convenient form of capsules will surely appeal to you. But let's start from the beginning. As you probably know, caffeine is a plant alkaloid that in its pure form is a bitter white powder. The effects of caffeine are similar to those of other methylxanthines (including those found in various teas and chocolates). These effects include mild stimulation of the CNS (or central nervous system), including wakefulness and cognition1.

Caffeine and physical activity

Caffeine reduces fatigue and increases concentration and alertness, and athletes regularly use it as an ergogenic agent, i.e. supporting exercise capacity. Caffeine-induced performance gains have been observed in both aerobic and anaerobic sports. According to scientific research, even smaller amounts of caffeine (1.0-2.0 mg/kg) can improve performance. It is most likely related to e.g. with reduced neuromuscular fatigue2. Caffeine is popular not only before physical activity, but also among people working mentally, due to the fact that it helps to increase alertness (measured as the speed of reaction time) and supports the improvement of focus and concentration3.

What is naringenin?

Our product Caffeine has been enriched with grapefruit extract, which is now standardized for the content of naringenin. You're probably wondering what kind of relationship this is. Well, naringenin belongs to a subgroup of flavonoids known as flavanones and is found mainly in citrus fruits and tomatoes. Citrus flavonoids exhibit a variety of biological properties4. The most recognized effect of flavonoids is their antioxidant activity. Naringenin is known as a free radical scavenger. And as it is well known, the regulation of cellular production of antioxidants plays an important role in the functioning of the human body5. In addition, the potential of naringenin to modulate glucose and lipid metabolism still arouses considerable interest and is the subject of numerous studies4.

What properties does grapefruit extract have?

Grapefruit supports the body's immunity, supports the defense system3. When it comes to naringenin itself, it has a wide biological effect on the human body. This includes reducing biomarkers of lipid peroxidation and protein carbonylation (this applies to the oxidation of amino acid residues), promotes carbohydrate metabolism, increases antioxidant defense, scavenges reactive oxygen species, modulates the activity of the immune system. It has also been reported to have a high ability to modulate signaling pathways related to fatty acid metabolism, which promotes fatty acid oxidation6.
