Black Widow 25 Review - Does This Hardcore Supplement Really Work? Are dangerous ingredients and side effects deal breakers?

Editor's Review: 3.5 / 5.0

black-widow-diet-pillsWell over half of all diet products on the market have absolutely NO scientific support. Let’s see whether or not Black Widow 25 is one of these. We decided to conduct an in-depth review, focusing closely on the side effects, ingredients, clinical studies and quality of customer care. We also took a good look at countless user comments posted online to see what people are saying. We then compressed all of the facts and feedback we found to give you the bottom line.

EDITOR'S TIP: Substitute Black Widow 25 with a proven fat burner such as Leptigen for better results.

What You Need To Know

First off, Black Widow 25 is a fat-burner made by Hi-Tech Pharmaceuticals, Inc. The ingredients are ephedra, vitamin B6, chromium picolinate, citrus aurantium (30% synephrine), vitamin B12, theobromine, white willow bark, yohimbe extract, caffeine anhydrous, kola nut, green tea, garcinia cambogia, panax ginseng, guarana, cayenne pepper, bladderwrack and ginger root. This company is located in Norcross, GA. They specialize in supplements for weight-loss, healthcare, muscle building and sexual enhancement. Black Widow 25 is intended to provide extreme energy, while assisting with weight management by boosting metabolism. It is taken daily and is fine for women and men.

Black Widow 25 has been available since 2013 and can be purchased via the company website. This product may give you an energy boost and it does contain some natural plant extracts, but read on…

Dangerous Ingredients – “Proceed With Caution?”

The first thing we considered with Black Widow 25 ingredients was that some could be dangerous. “We examined the formula used in Black Widow 25 capsules and must say we are very concerned about ephedra and synephrine. These are known for increasing blood pressure and causing accelerated heart rate,” says our Research Editor.

One customer commented, “Made my heart race like I just ran a marathon. No thanks!”

“Is this stuff safe? I feel real jittery and nauseous after taking,” asks another.

Serious Side Effects – “Another Concern”

Since Black Widow 25 capsules contain potent stimulants such as ephedra, they can obviously lead to some concerning adverse effects. One dieter revealed, “Pounding headache and heart racing after taking this product. Is that normal?”

According to another user, “This stuff will cause a major increase in blood pressure. No Joke.”

Our research has concluded that if a particular part of a weight-loss program or fat-loss supplement is especially concerning or bothersome (dangerous ingredients, high cost, serious side effects) the odds of real success are not good. Therefore if Black Widow 25 capsules do in fact cause serious adverse reactions in a number of people, this could be problematic.

The Science – “Proven Effective?”

Even though we at DietSpotlight search for clinical studies pertaining to each diet product we look at, we could not find any regarding Black Widow 25 capsules. We know that ephedra works, but we also can find a number of scientific reports that show verified side effects. Without so much against it, we’re not sure the dieter should take the chance on this one.

The Bottom Line – Does Black Widow 25 Work?

Hey – should you run out and buy this one today? While Black Widow 25 capsules do contain some natural plant extracts, we do not feel comfortable recommending this formula for safe weight management. The fact that this product contains ephedra is a big red flag. After all, this ingredient was banned in the United States. Furthermore, the actual cost of Black Widow 25 is not posted on the official website. Not to mention, there was an FDA investigation into this company.

If you would like to see more significant weight-loss results, we encourage you to go with a diet product that is both safe and backed by clinical trial results.

Among the best products we’ve seen in 2015 is one called Leptigen. This weight-loss pill contains a proprietary blend of four key ingredients, which are proven in documented clinical research to help increase fat loss and ignite metabolism. Moreover, we can’t locate any complaints of adverse effects and user reviews around the web express people are seeing real results.

Also, the makers of Leptigen are so confident in their product they’re offering a special trial offer, which is a good sign.

What You Should Know

Black Widow 25 contains 25 mg of ephedra. This supplement is banned under the laws passed by the Food and Drug Administration that control the sale of ephedra. Ephedra cannot be legally added to diet supplements per this law, so dieters need to be wary of ordering Black Widow 25 or any other diet pill claiming to contain ephedra. Many companies claim supplements contain ephedra, but a different extract is included in the formula than the banned ingredient proven to boost metabolism. In this case, the diet supplement would not be banned, but the supplement would not carry the benefits of ephedra, either.

List of Ingredients

  • Ephedra (Extract)
  • Citrus Aurantium (30% Synephrine)
  • White Willow Bark
  • Yohimbe
  • Caffeine Anhydrous
  • Guarana
  • Cayenne
  • Panax Ginseng
  • Ginger Root
  • Bladderwrack
  • Green Tea
  • Garcinia Cambogia
  • Kola Nut
  • Salicylic Acid USP
  • Theobromine
  • Chromium Picolinate
  • Vitamin B12
  • Vitamin B6

Product Features

Black Widow 25 contains ephedra, but the source of the ephedra is not revealed. This could mean the supplement is banned or it could mean the supplement contains an ineffective form of ephedra. If we take ephedra out of the equation, the supplement still poses risk of side effects from other ingredients. Aside from ephedra, Black Widow 25 contains eight stimulants - caffeine, theobromine, yohimbe, green tea, guarana, citrus aurantium, kola nut and garcinia cambogia. This is far too many stimulants. The dieter will feel increased energy, but that energy will soon be replaced with a racing heart rate and increased blood pressure. Other side effects may include nausea, vomiting, sleeplessness and death, in extreme cases. Despite the massive number of stimulants, we do find chromium picolinate on the Black Widow 25 ingredient list. At least the manufacturer was thinking about appetite control in addition to increasing metabolism. Chances are the dieter will not feel hungry when taking this supplement due to negative side effects of the stimulants, so the chromium is basically a useless ingredient.

Black Widow 25 is not the ideal weight loss supplement. The list of potential side effects is long and dangerous, not to mention the fact that the supplement contains ephedra. Ephedra is linked to at least two deaths and is currently monitored by the Food and Drug Administration. There are proven weight loss ingredients in this formula, but the effects of these ingredients are weighed down by the effects of the dangerous ingredients in the formula.

    I think it works great with weight loss.
    But the real thing i am worried about it is its side effects.
    I am using it from the last 2 days on empty stomach and then i go for a little jog in the morning and i go to gym in the evening..
    The very first day i feel a little disturbance in my heart beat.
    And on the day 2 i am not having any heart beat problem but having some bowel movement problem so i am worried should i continue with this supplemnt or should i discontinue it???
