Vitamin C may improve smokers' blood circulation

A dose of vitamin C may give a quick boost to the poorer-than-average blood circulation seen in healthy young smokers, a study suggests.
The study of 25 healthy men found that although smokers initially showed poorer results on a test of blood flow to the heart that changed after they took a large dose - 2 grams - of vitamin C.
Shortly after taking the vitamin, the 13 smokers showed blood circulation on par with that of the 12 non-smokers, according to findings published in a leading heart journal.
However, lest smokers think they can undo heart damage by chasing a cigarette with a vitamin C pill, the researchers say their findings underline the dangers of smoking.
Vitamin C is a potent antioxidant, a substance that helps clear the body of cell-damaging molecules called oxygen free radicals. Because of this, it's thought that the vitamin may counter the "oxidative stress" that smoking puts on the lining of the blood vessels - a mechanism by which smoking leads to artery disease.
The new study looked at the effect of oral vitamin C on coronary flow velocity reserve (CFVR), a measure of how well blood flow speeds up to help the heart when it's under high demands. Past research has shown that smokers show poorer blood-vessel dilation in response to blood flow, and have a diminished CFVR.
The research team used a non-invasive ultrasound technique to measure CFVR in smokers and non-smokers, before and after they took vitamin C.
They found that before taking the vitamin, smokers had a lower CFVR than non-smokers did. Two and four hours after the dose of vitamin C, however, smokers' average CFVR was "restored" to a more-normal level.
Though the men in the study were given a large dose of vitamin C, researchers pointed out that it's probably useless to take doses beyond 200 milligrams, because the body will excrete the excess.
Moreover, it's not clear that loading up on vitamin C can benefit smokers. Some trials have found that taking C supplements does not improve smokers' blood vessel function, at least in the short term.
Researchers said further, large-scale trials should look at whether daily vitamin C supplements cut smokers' long-term risk of coronary artery disease.

In general, a good daily multivitamin/mineral supplement improves your overall bodily functioning and boosts both your physical and mental health and well-being. Sometimes supplementation with specific nutrients may be more appropriate in order to address any individual specific needs. For example, CoQ10 is especially helpful for those at risk for heart disease, and Vitamins C and E, taken in combination to help ward off Alzheimer's disease. A multivitamin supplement usually contains the recommended daily dose of a variety of vitamins and other nutrients. Sometimes, multivitamin supplements are formulated for specific age groups, or individual conditions such as pregnancy. Multivitamins also are at their most efficient when they are in liquid form, as the body has been proven to absorb them five times more efficiently than multivitamins in pill form.

Many people report a feeling of general well being when they are taking their daily multivitamins regularly. The individual vitamins and nutrients in a quality daily multivitamin dose delivers to you their specific benefits of each individual vitamin, plus you get the combined (synergistic) benefits of all of the ingredients working together. Vitamin E, for example, a fat-soluble antioxidant vitamin helps to neutralize potentially damaging free radicals in the body and it is particularly important for the protection of cell membranes as well as maintaining healthy skin, heart and circulation, nerves, muscles and red blood cells. Vitamin C on the other hand is water soluble, but like Vitamin E, it is an antioxidant. It helps white blood cells combat infection, is essential for wound healing, for the formation of collagen, for healthy skin, and for the formation of other important structural materials in bones, teeth and capillaries. It also helps with the absorption of iron from plant sources. Vitamins D, K, A, and other nutrients in a multivitamin supplement all have specific beneficial effects on our bodies ranging from minimizing the risks of heart problems to helping to ward off Alzeheimer?s disease.

It is important to take your daily multivitamin in a liquid form regularly to enjoy these benefits to their fullest extent. Vigorous training, for example, increases the production of free radicals in the body. When involved in an exercise program, we should, therefore, increase the intake of antioxidants such as beta-carotene, vitamin C and vitamin E, and ensure you take adequate amounts of the proper vitamins and minerals required to maintain strong, healthy bones and joints such as calcium and iron. Also, older people over 55 years, convalescents, those who consume large amounts of alcohol, those with active, busy lives, people with colds, smokers, those exposed to excessive pollution, athletes and routine aspirin users need to take more daily and regular multivitamins.

Can I take ayurvedic medicines for infertility? My husbands sperm count is little bit low, and both of us are taking Ashwagandha churna with milk daily from past 3 months, how long should we continue this and can it be helful to get a child?
Has it worked out for any people ? We are trying for the second one from past 1 year, please suggest us.

I don't know if the Ashwagandha churna will work or not - but it has been used for a very long time in India as a restorative herb and specifically to increase potency/libido. My main concern with Ayurvedic medicine is not whether or not it works so much as whether or not it may contain high levels of heavy metal contaminaton - which has been a problem in India.

Before you seek out a doctor, I would suggest looking at lifestyle and supplement changes in the spirit of this section. After all, your husband does not have lowered sperm count due to a deficiency of pharmaceutical drugs, and 95% of those drugs have side effects. Low sperm count is becoming increasingly common in the US, likely due to increased toxic load, mineral deficiencies due to over-farmed soils, the SADS diet and processed food, and increasingly sedentary lifestyles. The average sperm count has dropped by over half in the last few decades.

Other common causes for low sperm count include:

* Infected semen
* Heat
* Obesity
* Pressure
* Frequent ejaculations
* Smoking, Excessive alcohol intake.
* Over exertion physically and mentally
* Zinc deficiency
* Infections present in prostate gland.
* Malformed genital organs.
* Anabolic steroid use

Here are some suggestions:

Lifestyle:

* Avoid the heat. High body temperatures have been shown to decrease sperm production. Avoid hot tubs, saunas and exposure to hot weather. Tight fitting shorts or prolonged laptop computer use also may increase the temperature of your testicles, decreasing sperm production.
* Make healthy lifestyle choices. Staying at a healthy weight and avoiding tobacco, excessive drinking and illegal drugs can all help reduce the risk of low sperm count.
* Have sex & masturbate less often - the more times you ejaculate, the less dense your semen will be. It's important to have sex on a regular basis around the time of ovulation, when your partner can get pregnant. But ejaculating more than a few times a week can reduce the number of sperm present in your semen. Maintain a gap of 3 days between two consecutive ejaculations.
* Refrain from habits like smoking, alcohol consumption etc. - Alcohol affects your liver function, which, in turn, causes a dramatic rise in estrogen levels. Even two drinks a day will have long-term effects on sperm production
* Exercise regularly.
* Eat Nutritious Food - Diet that's low in fat, and high in protein, vegetables, and whole grains is good for your health and for your sperm. Avoid bitter, astringent and spicy foods.Reduce caffeine intake
* Avoid heating of testicles - Wear loose, cotton boxer shorts, Avoid hot baths and saunas
* Lose any excess weight, which tends to cause testosterone/oestrogen imbalances.
* Reduce stress levels by learning relaxation techniques - Keep your mind and body healthy by regular practice of YOGA and MEDITATION.
* Massage body with herbal oil, which improves blood circulation.
* Make love in the early morning or afternoon. Sperm levels are often highest in the mornings

Supplements:

* Vitamin C protects sperm from oxidative damage. Supplementing vitamin C improves the quality of sperm in smokers. When sperm stick together (a condition called agglutination), fertility is reduced. Vitamin C reduces sperm agglutination, and supplementation with 200?1,000 mg per day increased the fertility of men with this condition in a controlled study. Many doctors recommend 1 gram of vitamin C per day for infertile men, particularly those diagnosed with sperm agglutination. However, a double-blind trial studying the effects of combined vitamin C and vitamin E supplementation found no improvements in semen quality among men with low sperm motility.
* Zinc deficiency leads to reduced numbers of sperm and impotence in men. Infertile men have been reported to have lower levels of zinc in their semen, than do men with normal fertility. Similarly, men with normal sperm density tend to have higher amounts of zinc in their semen, than do men with low sperm counts. In a controlled trial, 100 men with low sperm motility received either 57 mg of zinc twice daily or a placebo. After three months, there was significant improvement in sperm quality, sperm count, sperm motility, and fertilizing capacity of the sperm. The ideal amount of supplemental zinc remains unknown, but some doctors recommend 30 mg two times per day. Long-term zinc supplementation requires 1?2 mg of copper per day to prevent copper deficiency.
* Arginine, an amino acid found in many foods, is needed to produce sperm. Research, most of which is preliminary shows that several months of L-arginine supplementation increases sperm count, quality, and fertility. However, when the initial sperm count was extremely low (such as less than 10 million per ml), L-arginine supplementation produced little or no benefit. While some pregnancies have been attributed to arginine supplementation in preliminary reports, no controlled research has confirmed these claims. For infertile men with sperm counts greater than 10 million per milliliter, many doctors recommend up to 4 grams of L-arginine per day for several months.
* In a double-blind study of infertile men with reduced sperm motility, supplementation with selenium (100 mcg per day for three months) significantly increased sperm motility, but had no effect on sperm count. Eleven percent of 46 men receiving selenium achieved paternity, compared with none of 18 men receiving a placebo.
* Vitamin B12 is needed to maintain fertility. Vitamin B12 injections have increased sperm counts for men with low numbers of sperm. These results have been duplicated in double-blind research.34 In one study, a group of infertile men were given oral vitamin B12 supplements (1,500 mcg per day of methylcobalamin) for 2 to 13 months. Approximately 60% of those taking the supplement experienced improved sperm counts. However, controlled trials are needed to confirm these preliminary results. Men seeking vitamin B12 injections should consult a physician.
* L-carnitine is a substance made in the body and also found in supplements and some foods (such as meat). It appears to be necessary for normal functioning of sperm cells. In preliminary studies, supplementing with 3?4 grams per day for four months helped to normalize sperm motility in men with low sperm quality. While the majority of clinical trials have used L-carnitine, one preliminary trial found that acetylcarnitine (4 grams per day) may also prove useful for treatment of male infertility caused by low quantities of immobile sperm.
* Coenzyme Q10 (CoQ10) is a nutrient used by the body in the production of energy. While its exact role in the formation of sperm is unknown, there is evidence that as little as 10 mg per day (over a two-week period) will increase sperm count and motility. In one study, men with low sperm counts were given CoQ10 (60 mg per day for about three months). No significant change was noted in most sperm parameters, but a significant improvement was noted in in-vitro fertilization rates.
* Vitamin E deficiency in animals leads to infertility. In a preliminary human trial, 100?200 IU of vitamin E given daily to both partners of infertile couples led to a significant increase in fertility. Vitamin E supplementation may enhance fertility by decreasing free-radical damage to sperm cells. In another preliminary study, men with low fertilization rates in previous attempts at in vitro fertilization were given 200 IU of vitamin E per day for three months. After one month of supplementation, fertilization rates increased significantly, and the amount of oxidative stress on sperm cells decreased. .
* Preliminary research suggests that oral SAMe (S-adenosyl-L-methionine), in amounts of 800 mg per day, may also increase sperm activity in infertile men.
* Calcium is a key regulator of human sperm function. The concentration of calcium in semen determines sperm motility (i.e., the ability of sperm to move spontaneously). However, calcium deficiency has not been confirmed as a cause of male infertility nor is there any evidence that calcium supplementation improves male infertility.
* Asian ginseng may prove useful for male infertility. One preliminary study found that 4 grams of Asian ginseng per day for three months led to an improvement in sperm count and sperm motility.
* A small clinical trial found that healthy men who took dried maca powder had increased sperm counts and enhanced sperm motility.
* Other helpful herbs: Damiana, sarsparilla, saw palmetto, yohimbe, velvet bean, catuaba, chuchuhuasi and muira puama.

Why do my fingernails turn purple? when i am cold my fingernails turn purple my toes do too and my hands are always cold.
Why does that happen? is this normal?

Bluish or purple fingernail beds may be a symptom of peripheral cyanosis, which indicates oxygen deprivation.
purple finger nails usually is more noticeable when its cold. you probably just have poor circulation. also lack of a certain vitamin. It's most common in women. It also can be Raynauds disease which basically is a disorder of the blood vessels predominately in the hands and feet. Heres more info..Dark fingernails can be a sign of a few different health warnings, especially if you find fingernails turning purple.
Your nails should be a nice soft pinkish color indicating a healthy body, if you have dark nails such as your fingernails turn purple, then read on for possible causes....

Purple nails can be due to lack of oxygen in the body, sometimes people who smoke can experience purple fingernails as smoking reduces the amount of oxygen in the blood.

If you are a smoker and your fingernails are purple it is because your body is needing more oxygen and is taking this from other parts of your body such as your fingers, which is why you have a change in fingernail color.

You will experience purple nails if you are anemic or perhaps just low in iron. Taking vitamins for fingernails is a good idea. In the case of purple fingernails it is best to take an iron supplement first thing in the morning about an hour before breakfast and take it with a vitamin C supplement to help with absorption.

Sometimes dark nails can be contributed to circulatory problems, which will result in limited blood flow to your hands, legs and heart. Your blood vessels become blocked which obstructs the natural blood flow.
There are a couple of very powerful herbs you can take to help with your circulation, the first one is ginkgo biloba which has been used for centuries in helping improve circulation, and one which I take regularly is cayanne pepper.

I mix a small teaspoon of cayanne pepper in warm water, and drink it. It takes a bit of getting used to, but will definitely help you and if you are suffering from varicose or spider veins, it will help them too!

Exercise is another great way to help with circulatory problems, especially helping increase your oxygen intake.

People who suffer from anxiety can find their fingernails turn purple, along with anxiety can be dizziness and extreme shortness of breath.

Raynauds phenomenon is a disease which causes your veins to spasm and block blood to your hands and fingers causing fingernails turning purple. This is especially predominant when you are feeling stressed or exposed to the cold.

During an attack you can feel cold and numb from lack of blood flow and your fingers and toes may throb and tingle, fingernails may go from white to bluish purple to red.

If you have not been diagnosed with Raynauds phenomenon, and feel your purple fingernails could be this health problem, then seek a medical opinion.

If your fingernails are a purplish color bordering on black and the fingernail is separating from the nail bed, then you could be suffering from fingernail fungus.

You may find it is just because of poor circulation which is making your fingernails turn purple, taking the above mentioned herbs and exercising may help to bring your dark nails back to normal.

If this does not work, you are best to see a doctor so he can diagnose why you have dark fingernails.

How will one prevent from developing prostrate cancer? or avoiding prostrate problem in life

PROSTATE CANCER

You can reduce the risks of getting prostate cancer by doing the following things

PREVENTION OF PROSTATE CANCER
Prostate cancer can't be prevented, but you can take measures to reduce your risk or possibly slow the disease's progression.
The most important steps you can take to maintain prostate health ? and health in general ? are to eat well, keep physically active and see your doctor regularly.

a.- Eating well
i.- High-fat diets have been linked to prostate cancer. Therefore, limiting your intake of high-fat foods and emphasizing fruits, vegetables and whole fibers may help you reduce your risk.
ii.- Foods rich in lycopenes, an antioxidant, also may help lower your prostate cancer risk. These foods include
raw or cooked tomatoes,
tomato products,
grapefruit
and watermelon.
iii.- Garlic and cruciferous vegetables such as arugula, bok choy, broccoli, brussels sprouts, cabbage and cauliflower also may help fight cancer.

iv.-Soy products contain isoflavones that seem to keep testosterone in check. Because prostate cancer feeds off testosterone, isoflavones may reduce the risk and progression of the disease.

v.- Vitamin E has shown promise in reducing the risk of prostate cancer among smokers. More research is needed, however, to fully determine the extent of these benefits of vitamin E.

b.- Getting regular exercise
- Regular exercise can help prevent a heart attack and conditions such as high blood pressure and high cholesterol.
- When it comes to cancer, the data aren't as clear-cut, but studies do indicate that regular exercise may reduce your cancer risk, including prostate cancer.

- Exercise has been shown to strengthen your immune system, improve circulation and speed digestion ? all of which may play a role in cancer prevention.
- Exercise also helps to prevent obesity, another potential risk factor for some cancers.

- Regular exercise may also minimize your symptoms and reduce your risk of prostate gland enlargement, or benign prostatic hyperplasia (BPH).
- Men who are physically active usually have less severe symptoms than men who get little exercise do.

c.- Drug protection
Research on prostate cancer prevention has shown that the drug finasteride (Proscar, Propecia) can prevent or delay the onset of prostate cancer in men 55 years and older. This drug is currently used to control prostate gland enlargement and hair loss in men. However, finasteride also has been shown to contribute to increasing sexual side effects and to slightly raise the risk of developing higher grade prostate cancer. At the time, this drug isn't routinely recommended to prevent prostate cancer. However, if you're at higher risk for developing prostate cancer, discuss the use of finasteride with your doctor.

d.- Finally, nonsteroidal anti-inflammatory drugs (NSAIDS) might prevent prostate cancer.
- These drugs include
ibuprofen (Advil, Motrin, others)
and naproxen (Aleve).
- NSAIDS inhibit an enzyme called COX-2, which is found in prostate cancer cells.
- More studies are needed to confirm whether NSAID use actually results in lower rates of prostate cancer or reduced deaths from the disease.
