Generally, Arginine is seen as one of the least toxic of the amino acids and can be taken by healthy individuals without risk of adverse effects, even in relatively high doses. However, to reduce the risk of side effects, you should take only as much L-Arginine as can be found in foods that are high in this amino acid.
The main effects that have been reported by people taking L-Arginine include bloating, diarrhea, and abdominal cramps. However, these are generally mild and those who suffer from them will usually see the effects go away after several days once your body gets used to the increased L-Arginine intake. If the symptoms don’t go away, however, you should stop taking the supplement and see your doctor, since you may be sensitive or have an allergy to L-Arginine.
The usual recommended dosage for L-Arginine is from 5 grams to 30 grams when taken orally. For people who are advised to take this supplement to treat heart disease, the usual dose is around five grams a day to help reduce the risk of heart attacks and strokes. However, you should seek the recommendation of your doctor to determine the appropriate dosage for you to take.
However, there are certain types of people who should either avoid taking L-Arginine or use it with care. Women who are pregnant or those who are breastfeeding should either not take it or take the supplement only in small doses. Growing children should also use the supplement with caution since they usually already get the amount of Arginine they need from their daily diets and should only be given more when it is clear that they suffer from a deficiency.
In addition, if you are taking prescription medication, you should talk with your doctor first to determine if there are any possible contraindications that could lead to negative interactions. Never take an L-Arginine supplement without talking to a health professional or stop taking your maintenance medication since this may have serious health consequences.
There are also some indications that people who suffer from herpes should not take L-Arginine since it may increase the severity of outbreaks. However, this subject is still open to debate since there are also authorities who believe there is no link between Arginine and increased risk of herpes outbreaks. The Herpes Resource Center of the American Social Health Association, in particular, does not recommend eliminating Arginine-rich foods since they believe there is no evidence that they can result in more outbreaks.
To understand how L-Arginine can help with erectile dysfunction, you have to know how erections happen. There are spongy tissues known as corpora cavernosa that line the shaft of the penis, which are made up of small veins and arteries. When a man becomes aroused, the arteries in the corpora cavernosa dilate, allowing blood to flow into them and making the penis erect. When men suffer from high blood pressure and similar conditions that prevent arteries from dilating, they experience erectile dysfunction and consistently have difficulty sustaining erections.
L-Arginine helps to address erectile dysfunction by helping the body produce more Nitrous Oxide. This ensures normal dilation of the blood vessels so that men suffering from ED can achieve normal erections. L-Arginine supplements are often seen as a natural alternative to Viagra and similar remedies for sexual dysfunction.
Women who are suffering from sexual problems such as low sex drive and inability to have orgasms can also benefit from taking L-Arginine. Some research has suggested that these problems are related to poor blood flow in the clitoral tissue. Increasing Nitrous Oxide production in the body can result in more blood flowing to the clitoris. This can heighten its sensitivity and make it more responsive when stimulated during sex, making it more likely that women can achieve orgasm.
Arginine may also help boost the sex drive of both men and women. This could be because Nitrous Oxide is a neurotransmitter that helps the brain transmit signals between neural cells. In addition, the presence of more Nitrous Oxide in the body may also help make sex hormones such as testosterone more available to increase libido.
There are also some reports that men who suffer from low sperm counts or have poor sperm motility have enjoyed improved fertility and increased their chances of being able to conceive by taking L-Arginine daily. If the couple is trying to conceive through in-vitro fertilization, L-Arginine may help increase the chances of success by improving the quality of sperm.
L-Arginine supplements designed to treat sexual dysfunction work best when they are combined with yohimbe. Yohimbe is an herb that comes from the bark of a tree that is commonly found in Africa, and it contains yohimbine, a powerful stimulant. When used during sex, it helps to stimulate the brain and promote increased blood flow to the sexual organs. Thus, its effects compliment those of Arginine. But, it should only be used under the supervision of a doctor or health professional to avoid the risk of adverse effects.
