In the human body, folic acid interacts with vitamin B12, pantothenic acid, and vitamin B7 (also called vitamin H or biotin). The signs of biotin deficiency can be hair loss, skin inflammation, skin pallor, mucous membrane inflammation, depression, drowsiness, anemia, blood sugar disorders, muscle pain, poor appetite, nausea, and insomnia. Besides, a person feels tired, irritable and depressed. Consequently, male libido and sexual activity reduce. In turn, this negatively affects sexual performance.
The researchers reasoned from other studies that when the degree of endothelial dysfunction and atherosclerosis are more severe, the effects of niacin and statins as lipid-lowering agents are also more apparent. Their current study seemed to bear this out. Also, in another study assessing the effect of a PDE5 inhibitor in patients using a statin, patients with higher baseline serum LDL-C had better improvement in erectile function after the use of a PDE5 inhibitor. This supports the researchers’ hypothesis that patients with potentially more serious endothelial dysfunction, such as those with higher LDL-C levels, may have better response to the combination usage of a PDE5 inhibitor and niacin.
Controlling stress, having a healthy diet, and getting enough sleep to create a good foundation for sexual satisfaction. But sometimes the basics aren’t quite enough. Millions of men experience erectile dysfunction (ED), but ED can usually be successfully treated with prescription medications like Viagra, Levitra, Staxyn, and Cialis. These drugs have helped men understand that ED isn’t all in their mind, have opened up the topic to a more honest discussion, and have transformed many men’s sex lives.

Having your current medication checked – if you are taking medication already, it could be that your erection problems are a side effect. Have a doctor check whether this is the cause of your problems and if it is, you might be able to switch medications and then find that your erectile dysfunction goes away completely – or at least improves. Medications that can cause erection problems include:
Also to be considered, patients were not using PDE5 inhibitors during the study period. Therefore it wasn’t determined whether the combined use with niacin can enhance the response of PDE5 inhibitors. Another limitation on the study results was the exclusion of the partner’s assessments. This would help to provide a more comprehensive assessment of the efficacy of niacin.
Researchers at Johns Hopkins University last year looked at 3,400 healthy Americans and found that men who were vitamin D deficient were 32% more likely to have trouble getting it up than those with sufficient levels, even after adjusting for other ED risk factors. In fact, the connection is so common, Walker says D levels are something he always checks in ED patients. Why? The sunshine vitamin is crucial for keeping the endothelial cells that line blood vessels healthy. Without enough of the stuff, blood flow is inhibited, affecting everything from your heart to your hard-on.

Aerobic exercises and pelvic floor exercises are two of the best methods to start with. As a matter of fact, you can see improvements on your condition without having to witness the side effects of other male enhancement products. For one, there are certain male enhancement products which should not be taken if you are suffering from other types of medical condition. For instance, if the product contains substances that may react to the male enhancement ingredients of a product, you may suffer from certain consequences.

Our bodies are designed to be active and in motion. By keeping active and engaging in regular aerobic exercise, you increase the blood flow to your muscles, and your penis along the way. One of the most interesting things about increasing your blood flow is that it becomes a signal to your blood vessels to grow and get wider. It benefits your brain, your heart, and your erection. The principle of "use it or lose it" is the best advise one can follow. In fact, if you don't engage in sexual activity at least once or twice a week, it would be beneficial to masturbate. This not only helps with prostate health, but encourages the blood vessels that contribute to your erection to maintain their patency and flow. 
The substance that gives hot peppers their kick can also give you some kick in the pants: Studies have associated the natural chemical with increased testosterone levels. In animal studies, capsaicin has also shown to increase the size of sex organs, while simultaneously decreasing belly fat. A 2014 study from France also found that men who ate more spicy food had higher testosterone levels than those who ate less. You can consume capsaicin via peppers, chili powder or a cayenne supplement.
Guay and Spark observed independently (unpublished data) that yohimbine was associated with a very poor response in cigarette smokers. This is believed to be relevant, because studies several decades ago may have included a large percentage of smokers, which only recently has been recognized as a risk factor for erectile dysfunction. We tested this hypothesis by studying nonsmoking men with documented organic impotence and by judging whether any possible effect might be related to adrenal or testicular hormones, which, to our knowledge, has not been studied.
Ginseng, specifically “red ginseng,” is known as the “herbal Viagra” that helps puts to rest men’s bedroom woes. Red ginseng is when the root has been steamed and then dried. The ginseng root is the part of the plant that is mostly used as a natural remedy when in its supplement form. However, the plant must be grown for a minimum of five years before it can be used. In a 2008 review, seven studies on red ginseng and ED, ranging in dosages from 600 to 1,000 milligrams three times a day, were found to provide evidence for the effectiveness of the herb in ED treatment.
The search criteria identified 210 studies from 1972 to 2010; on inserting randomized controlled trials only 26 studies were identified out of which only 5 met the inclusion criteria and 21 studies did not meet the inclusion criteria, hence, were excluded. Five (18, 24–27) randomized controlled trials (RCTs) met the inclusion criteria; studies involved the use of aerobic exercise in the management of ED, the IIEF was the assessment tool for ED and also involved control groups. A total of 385 subjects were involved: Lamina et al (25), n=43; Lamina et al (26), n=43; Esposito et al (18), n= 110; Kalka et al (27), n= 129; Maio, Saraed and Marchiori (24), n= 60.
ED can be caused by a handful of things, but one thing’s for sure: You need a healthy supply of the neurotransmitter nitric oxide (NO) to get and maintain an erection. NO is produced in nerve tissue and helps jolt your Johnson by relaxing the smooth muscle so blood can fill the penis. After the initial release of NO, your body releases a cascade of chemicals—including more of the neurotransmitter—to help keep you hard and happy, according to a study in the Proceedings of the National Academy of Sciences.

The response to yohimbine did not vary with patient age; the responders were 60.3 y of age vs 60.0 for the nonresponders (Table 4; P=0.106). The number of medical risk factors was slightly higher in the nonresponders (2.3 per person) compared with the responders (1.8 per person), but this difference was not significant (P=0.346). Documenting the quality of the men's erections in the office with a simple grading system showed a significant difference at the end of the study between responders and nonresponders. For the responders, the value was 3.0 compared with 1.9 for the nonresponders (P<0.001). This result correlated with the overall sexual satisfaction of patients who stated whether or not they were able to engage in regular sexual intercourse.
