Offered by Hi-Tech Pharmaceuticals, Black Widow 25 claims to burn fat quickly and reduce weight in a short time. It certainly includes some interesting ingredients, but there are some banned ingredients, such as ephedra. Should you put your money on this weight loss supplement? Here is our review to help you decide.
Black Widow 25 is one of many weight loss supplements available today, but it claims to be different and more powerful because it contains ephedra. It also has caffeine, green tea extract, and other ingredients that are supposed to improve your energy levels, elevate mood, and suppress your appetite at the same time. The presence of stimulants may lead to side effects though.
Black Widow 25 contains ephedra, caffeine, and other stimulants, so it is not safe for pregnant or breastfeeding women. Increased heart rate, nausea, vomiting, increased blood pressure, and insomnia are common side effects.
You will be paying $31.95 to get a 1-month supply of Black Widow 25.
Black Widow 25 makes big claims mainly because it combines stimulants such as ephedra, caffeine, green tea extract, guarana seed extract, and even yohimbe. Black Widow 25 may boost your metabolism a little, but you may end up dealing with several side effects, such as irritability, mood changes, insomnia, elevated heart rate, and more. It uses a proprietary blend, so it is hard to say exactly how much of each ingredient is there in each serving. The price is on the higher side and you may not get a refund depending on where you go to make a purchase. Our verdict: avoid Black Widow 25, pay attention to your diet and exercise regularly to lose weight in a healthy way.
While Black Widow 25 claims to be one of the best weight loss supplements out there, you may want to avoid it for so many reasons. Yes, its ingredient profile may look impressive, but that does not mean it is going to work for you, and that is mainly because so many of its ingredients are either under-dosed or not supported by scientific evidence. Some of its ingredients may actually lead to several side effects, such as ephedra.
One of many active ingredients in Black Widow 25 is ephedra extract. Usually used in Traditional Chinese Medicine, ephedra is an herb that may help treat asthma, bronchitis, and hay fever. It may also prove effective in the treatment of nasal congestion, cough, fever, chills, and cough. Many OTC remedies contain ephedra extract in the form of pseudoephedrine, but it is now banned in many countries because of its potential side effect. The FDA has banned supplements that contain ephedra, ephedrine, pinelllia, norephedrine, Sida cordifolia, or other forms of ephedrine.
Even if you get it through Black Window 25, you are not going to get significant reduction in your weight. Not much scientific evidence is available to support the weight loss properties of ephedra. Some studies suggesting that it may trigger fat loss have also included other ingredients in the mix. For instance:
For example, in a double-blind, placebo-controlled trial, 180 overweight individuals were placed on a weight-loss diet and given either ephedrine/caffeine (20 mg/200 mg), ephedrine alone (20 mg), caffeine alone (200 mg), or placebo, 3 times daily for 24 weeks. The results showed that the ephedrine/caffeine treatment significantly enhanced weight loss, resulting in a loss of more than 36 pounds as compared to only 29 pounds in the placebo group, a 7-pound difference. Neither ephedrine nor caffeine alone produced any benefit.
It means that ephedra may or may not help you lose weight, but it certainly exposes you to an increased risk of developing problems like nausea, mood changes, anxiety, palpitations, hypertension, heart attacks, seizures, and even death.
This proprietary blend also includes chromium picolinate. Many weight loss supplements contain chromium because it may help regulate glucose metabolism by making your body use insulin more effectively. It is also supposed to help with fat metabolism. Unfortunately, there is not enough scientific research confirming these claims associated with chromium supplementation.
At least 12 placebo-controlled studies have compared the effect of chromium supplementation (172–1,000 μg/day of chromium as chromium picolinate) with or without an exercise program on lean body mass and measures of body fat. In general, the studies that used the most sensitive and accurate methods of measuring body fat and lean mass (dual energy X-ray absorbtiometry or DEXA and hydrodensitometry or underwater weighing) did not find a beneficial effect of chromium supplementation on body composition.
However, some studies have found chromium effective in reducing weight. For instance:
Recently, a meta-analysis of 11 randomised, double-blind, placebo-controlled trials in 866 overweight or obese subjects found a significant 0.50-kilogram (1.10-pound) reduction in body weight with supplemental chromium (most exclusively in the form of chromium picolinate) at doses between 137 μg/day and 1,000 μg/day for 8–24 weeks. However, such a small change did not reach a clinically significant weight loss of ≥5% of the initial body weight.
Even in this case, you are not going to lose a lot of weight by using Black Widow 25. It may actually be quite ineffective because there is no information about how much of chromium picolinate is there in the formula. The same issue is associated with yohimbe – another ingredient in Black Widow 25 with little scientific evidence to prove its role in weight loss.
You have to take one capsule with each meal – so that will be three capsules a day. Do not take more than 3 capsules per 24-hour period.
Yohimbe is usually used to treat sexual dysfunction in men mainly because it works as an alpha-2 receptor antagonist. However, many weight loss supplements include it in the blend thinking that it affects body mass in a positive way. Unfortunately, studies have not shown consistent results to confirm the benefits of yohimbe to lose weight. For instance:
In a small clinical trial, yohimbine (5 mg taken 4 times/day) resulted in greater weight loss (mean weight loss 3.55 kg) than placebo (mean weight loss 2.21 kg) in 20 obese females (mean BMI 40 and 43 for placebo and yohimbine groups, respectively) who followed a low-energy diet (1,000 kcal/day) for 3 weeks.
It shows that yohimbe may help trigger weight loss, but other studies do not confirm these results. For instance:
A clinical trial in 47 men (weighing>20% more than ideal body weight), high-dose yohimbine (peak dose 43 mg/day) for 6 months had no effect on body weight or body fat compared with placebo.
The authors of a 2011 review of yohimbe concluded that no conclusive evidence indicates that yohimbe affects body weight or body mass.
The author of a 2010 review of yohimbe reached similar conclusions, noting that results from small human trials of yohimbine for weight loss are contradictory and the evidence base is insufficient to support a weight loss claim for this compound.
It means that you may not notice any change in your weight after taking Black Widow that contains yohimbe as a main active ingredient. Similarly, you should not hope for a quick reduction in weight just because you think it contains ginger root extract.
It supposedly works by boosting thermogenesis, which in turn increases the number of calories you burn throughout the day. Some supplement manufacturers believe ginger root is a good addition because it inhibits the absorption of fat in your body. There are some animal studies suggesting that ginger root can trigger fat loss, but human studies have failed to find reliable evidence. Some studies have actually found ginger extract completely ineffective in boosting weight loss.
This study looked at the effect of resistance training and ginger supplementation for 10 weeks on a group of 32 obese men. The men were split into four groups – placebo, ginger 1g/day, resistance training plus placebo, and resistance training plus 1g/day ginger. They found that although ginger did reduce obesity-associated inflammation, it seemed to have no significant impact on weight loss.
Black Widow 25 also provides you with a significant amount of caffeine. It also includes green tea extract and guarana seed extract, which add to the levels of caffeine in this supplement. Caffeine is supposed to work by increasing your metabolic rate. However, some experts say that there is little evidence suggesting that caffeine can lead to significant weight loss. It is thought that caffeine works by suppressing appetite and stimulating thermogenesis. The problem is that studies showing the positive effects of caffeine are done on animals or are of very poor quality. The addition of guarana provides you with even more caffeine – guarana extract contains more caffeine than coffee beans.
There are many other ingredients with no scientific evidence to work as a fat burner. Cayenne is one example. No studies show that it works as a fat burner. There is some evidence that it may help suppress appetite. By eating less, you may reduce your caloric intake, which may help reduce weight. This does not work for everyone and not all studies agree that capsaicin works this way. Similarly, Korean ginseng or Panax ginseng may offer some health benefits, but there is no reliable scientific evidence to support the use of Korean ginseng as a weight-loss aid. Some studies suggest that it helps your body metabolise carbs in a better way and causes weight loss. Not all studies agree though.
B-vitamins also fall in the same category of ‘ineffective’ ingredients. It is true that both vitamin B12 and vitamin B6 are essential for several bodily functions, but not many studies have found evidence to confirm that B-vitamins support fat loss. Vitamin B6 may help a bit because it stimulates the metabolism of lipids and may help burn excess fat. However, the problem is that getting excess vitamin B6 can overstimulate your thyroid gland, and it may help you lose weight but it can lead to hormonal imbalance, which results in serious health complications. Similarly, studies show that a low vitamin B12 levels can actually lower your weight – getting too much of it may increase appetite and result in weight gain.
Overall, it is clear that Black Widow 25 does not have scientifically proven fat burners, and it also includes banned ingredients, which may make you deal with some serious side effects. Considering its ingredient profile, it may not be the most affordable weight loss supplement either. So, do not waste your money and look for something that has scientifically proven ingredients and positive customer reviews.
Black Widow 25 contains several ingredients, and some of them are stimulants that may produce side effects but may still help boost fat loss. Here is what the official website says regarding what Black Widow 25 can do:
Unfortunately, it does not work the way you might think. It contains natural ingredients, but it can lead to several side effects because most of its so-called weight-loss benefits come from its caffeine content. Ephedra is a banned ingredient in many countries and also works as a stimulant. Guarana seed extract and yohimbe are also included because of their stimulating properties. Regular use of these ingredients may lead to several side effects, especially when you do not know much about how much of each ingredient is there in the blend. So, avoid it and look for a scientifically proven way to lose weight.
You can find many natural ingredients in Black Widow, including Ephedra extract, which is banned in many countries. Here is more about some other ingredients found in this weight loss supplement.
Black Widow 25 contains yohimbe that may cause side effects when you take high doses. There is no information about how much of it is there in this supplement, so you are always at an increased risk of experiencing side effects, such as hypertension, headaches, tachycardia, agitation, cardiac failure, myocardial infarction, and more.
You also find Korean ginseng in Black Widow 25 that can cause several side effects, such as skin rashes, dizziness, headaches, changes in blood pressure, increased heart rate, vaginal bleeding, mood changes, breast pain, diarrhoea, and other menstrual problems. In some cases, Korean ginseng is linked to serious side effects such as severe allergic reactions, liver damage, and a skin condition called Stevens-Johnson syndrome.
You get a significant amount of caffeine from Black Widow 25, which can also make you deal with problems like nausea, irritability, increased heart rate, palpitations, and mood changes. Caffeine can also interfere with your sleep and lead to insomnia.
You should not take it if you are pregnant or breastfeeding.
Black Widow 25 does not have many positive customer reviews, and it indicates that it is not as effective as it claims to be.
I have been using it for some time now but have not lost any weight.
I do not think it is for me because it makes me irritable and affects my sleep as well.
