What Is Estrin-D?

By HighYa Research Team
Published on: Feb 13, 2017

Branded as the first diet pill for “real women,” Estrin-D promises to boost metabolism and burn more calories, support hormonal balance, and provide all the energy you’ll need—even when you’re not working out.

In other words, it claims to address the three essential factors needed to successfully lose weight. Not only this, we’re told you’ll lose weight in all the right places, while looking and feeling younger.

Look, there’s no question that shedding pounds can deliver widespread benefits, including boosted self-image, increased energy, and a more youthful appearance.

But the real question here is: can Estrin-D deliver real-world weight loss? Or, at least better weight loss than exercising regularly and adhering to a sensible diet?

Even then, will Estrin-D provide the most value for your dollar? That’s exactly what we help you discern.

Do You Remember When You Could Lose 10-15 Pounds in a Few Days?

If so, (outside of illness and injury) one of two things probably occurred. Either a) you had an incredible metabolism that should’ve been scientifically studied, or b) you went on a crash diet.

If it’s the former, congratulations! If the latter, crash diets (even for a brief period of time) can lead to side effects like nutrient deficiency, dehydration, cardiac stress, a weakened immune system, and even a slowed metabolism—making you much more likely to quickly regain anything you’ve lost.

What’s the point in saying all of this? Some of the first words consumers read on the Estrin-D website are,Remember when you could lose 10 or 15 pounds in just a few days?”

First, unless your health was compromised, we think very few real-world consumers will relate to this statement.

Second, in our opinion, while the manufacturer doesn't expressly say it, this statement could foreseeably set unrealistic expectations about the amount of weight Estrin-D might reasonably help someone lose.

Why? According to the CDC, healthy weight loss is 1-2 pounds per week. This is because a pound of fat is equivalent to 3,500 calories. So, by reducing your intake by 500 calories per day (through a combination of diet and exercise), you can expect to lose about a pound or so per week.

Given this information, is there anything contained in Estrin-D that will help improve your weight loss results, outside of what you could achieve through diet and exercise?

Are Estrin-D’s Ingredients Effective For Weight Loss?

While there weren’t any ingredients listed on the Estrin-D website, we called customer service and spoke with a friendly representative who let us know it contains the following (take two capsules 15 minutes before each main meal):

  • Yerba Mate
  • Guarana Seed
  • Caffeine
  • Damiana Leaf
  • Green Tea
  • Ginger Root
  • Kola Nut Seed
  • DHEA
  • Schisandra Fruit Powder
  • Chinese Skullcap Root
  • Rhodiola Crenulata Root
  • Cocoa Seed
  • Jujube Fruit
  • Black Tea
  • Vitamin D
  • Vitamin B6
  • Magnesium

According to authoritative websites like WebMD and Examine.com, none of these ingredients have sufficient clinical evidence proving them to be effective for the weight loss or hormonal balance promoted by Estrin-D.

This isn’t to say they’re not without their benefits, though. For example, ginger may help address nausea, osteoarthritis, and dizziness, while DHEA seems to be effective for aging skin and depression.

Schisandra may help improve mental performance (as might caffeine), cocoa may reduce high blood pressure, and vitamin D could help treat psoriasis.

Taken together, it doesn’t appear the available clinical evidence supports the manufacturer’s claims. Will these ingredients cause any harm, though?

What About Potential Estrin-D Side Effects?

If you’ve ever consumed too much caffeine, you know that it can cause temporary jitteriness, nervousness, and insomnia. This is especially relevant if you’re sensitive to stimulants, since Estrin-D contains the natural caffeine found in yerba mate and black tea, as well as added caffeine (along with no dosages listed).

Further, DHEA can sometimes cause acne, hair loss, and high blood pressure. For rhodiola and jujube, side effects are largely unknown.

Outside of this, the most common side effect associated with these ingredients is mild digestive upset.

How Much Does Estrin-D Cost?

Estrin-D is available in the following quantities:

  • 30-Day Supply (2 x 90ct bottles): $79.99
  • 60-Day Supply (4 x 90ct bottles): $127.98

Like most Covaxil Laboratories products, Estrin-D comes with a 30-day money back guarantee, less S&H. In order to request one, you'll need to call customer service at 800-898-5153 for an RMA.

Important note: All Estrin-D orders are subject to an arbitration agreement, which means you’ll waive your rights to a related trial by jury or joining a class action lawsuit.

Are these prices delivering real-world results?

What Can We Learn About Estrin-D Reviews & the Company’s Public Reputation?

Estrin-D seemed to have been around for a few years at the time of our research, so there was a fair amount of online customer feedback.

On Amazon, Estrin-D had 65 customer reviews and an average rating of 3.8 stars. There, common compliments referenced effective results (lost weight, increased energy, reduced appetite) and competitive price.

On the flip side, common complaints related to no results and high stimulant content, leading to jitteriness, nervousness, upset stomach.

Estrin-D had a similar 4-star rating on Walgreens.com and Walmart.com, with much of the same feedback.

While digging around, we learned that a class action lawsuit was filed in 2008 for a weight loss supplement named Akävar, which appeared to be only a rebranded version of Estrin-D. According to the suit:

“Akävar has not undergone scientific evaluation by a team of doctors, nor has Akävar been tested in controlled random clinical trials.”

However, it’s important to note that Estrin-D was marketed at that time by a company named Basic Research, who was also the defendant a 2006 false advertising settlement that cost the company $3 million.

On the other hand, Estrin-D is currently marketed by Covaxil Laboratories who makes other popular supplements like Triadlean, Trivestin, and NuraDyne. Searching online, they appear to be the same company.

Here on HighYa, NuraDyne had one reader review and a 2-star rating, who complained that it didn’t work.

Obviously, none of this is to necessarily imply what you’ll experience with Estrin-D. We’re just providing you with the relevant information.

Does Estrin-D Have Any Competition?

As you probably understand already, Estrin-D is swimming in competition. Type “weight loss supplement” into your nearest search engine, and you'll have more options than you could ever hope to try—most of which make the same claims as Estrin-D.

And if you add menopause-specific supplements to the mix, your options only increase exponentially. This includes popular options like Leptigen, Metabo Matrix, Aptulux, Ageless Female, Estrinol, and Slimfy.

Like most nutritional supplements, these products tend to come with less-than-stellar customer feedback (typically two stars or lower) claiming that they didn’t work as advertised. Or that if they did, the results often weren’t worth the price.

Clearly, Estrin-D comes from a completely different manufacturer than these other products, and also seems to come with mostly positive consumer reviews, so there’s not necessarily a direct link.

Given this common feedback, though, we think you might want to keep your expectations realistic.

What Can “Real Women” Expect From Estrin-D?

While the manufacturer never tells us who “real women” are, based on what we learned during our research and from authoritative websites, it seems unlikely that Estrin-D will help any women lose meaningfully more weight than diet and exercise alone.

Sure, Estrin-D's caffeine content (again, we're not told how much) could foreseeably provide an energy boost and somewhat curb appetite, but the ingredients in its formulation don't appear to be anywhere near as effective as the manufacturer advertises for helping to shed unwanted pounds.

What can you do from here? The HighYa team’s only goal is to pass along the information and leave the final decision up to you.

From this perspective, if we were looking to get the most value for our money (after all, we’re consumers too!), we’d probably speak with our doctor about any weight loss issues we’re experiencing, who can help formulate a plan.

At that time, we could also ask if they believe Estrin-D’s ingredients will deliver results in line with its not-insignificant price.
