Riboxin in sports

In the body inosine (riboksin) supports the transport of oxygen to the cells of the heart and skeletal muscles. It helps to synthesize ATP (our main fuel), and supports blood flow. Despite the fact that in the 90s there was a lot of hype because of inosine in sports, studies have shown that it has little positive effects for physical activity. Inosine origins include brewer’s yeast and meat by-products such as heart and liver. It is also formed naturally in all human tissues, especially in the heart and skeletal muscles.

Riboxin in bodybuilding

Inosine gained popularity among active people in the early 1990s. It is a precursor to adenosine. His supporters argued that the drug can promote oxygen exchange, insulin release, muscle building, and increase energy and endurance for workouts. Unfortunately, most of the research carried out with the addition of inosine, showed that this nutrient is significantly behind the expected effects. Riboxin was also quite effective for athletes who felt tired during the competition and preparation for them. But still, there are much more effective drugs to increase energy and endurance. Especially in bodybuilding, the athlete tries to choose products that will help to solve his problems with maximal effectiveness. For example, to increase muscle mass, reduce fat and increase productivity. Unfortunately, Riboxin will not be able to give you at least some of these effects. Riboxin for weight loss also does not work, so use it on cutting phase of program makes no sense.

Among the fans of “old school” sports pharmacology, it is believed that Riboxin tablets can increase energy and endurance through energy production by regenerating the primary fuel used by muscles. They can supposedly help stimulate blood circulation and transport increased oxygen to muscle cells.

But, of course, everyone decides for themselves what pharmaceutical industry increases athletic performance. If you still decide to try this drug on yourself, then we will describe further medical benefits and how to take Riboxin athletes.

Inosine in medicine

Inosine may be useful in controlling some forms of heart disease, such as irregular heartbeat. Some studies have also shown that Riboxin can be useful for people with Tourette’s syndrome and neurological disorders. It can be prescribed for the treatment of ulcers of the stomach and duodenum.

From the above it can be concluded that inosine can be useful in:

  • fatigue and physical weakness;
  • lack of oxygen;
  • violation of immune function;
  • cardiovascular diseases;
  • Tourette’s syndrome;
  • peptic ulcer of the stomach and intestines.

How to take Riboxin

If you wonder: how to take Riboxin in sport, we can give you an approximate recommendation on dosage and regimen. It should be taken before meals. Athletes take from 1.5 to 2.5 g of Riboxin a day. But you need to start with a smaller dose of 0.6 – 0.8 g dividing it into 3 or 4 doses. If you notice that there are no side effects, feel free to increase the dosage to the recommended limits. The cycle lasts a month (4 weeks) the minimum and maximum up to 3 months.

If you have kidney failure or gout, then use Riboxin is strictly contraindicated. Be attentive to your body and then you will get more benefit than harm from the drugs you use.

Riboxin side effects

Inosine is considered to be a safe drug. Despite the absence of side effects, long-term use and a significant excess of the dosage of Riboxin should be avoided. The study, which was attended by 7 people, showed that high doses of inosine (from 5000 to 10000 mg per day for 5-10 days) can increase the risk of problems with kidney stones and gout. Inosine safety for young children, pregnant or nursing women is not established. If you feel an allergic reaction, itching on the skin, you should immediately stop using the drug and consult a doctor. You can also take antihistamines.
