Effective female fat burner supplements can do wonders for your weight loss, energy levels, and self-confidence.
But, they can also do a lot of harm if you don’t make the right choice.
With plenty of female fat burners on the market these days, picking the best one is similar to finding a needle in the haystack.
That’s why I’ve decided to review two of the best fat burner products - Leanbean vs Hourglass.
I’ve compared their ingredients, side effects, pricing, and answered some frequently asked questions to help you reach the final verdict.
So, let’s see which product comes out on top.
What Is LeanBean?
Leanbean is produced by Ultimate Life, a renowned company from the supplement industry. It’s an effective fat burner and appetite suppressant with some added vitamins and minerals like B6, B12, and Zinc, which are vital for your body functions, reducing fatigue, and enhancing endurance.
Most fat burning supplements popular among users contain harsh stimulants and other harmful substances which may be dangerous for your health. 
Leanbean doesn’t. (I’ll write more about the ingredients in a bit.) Its formula is claimed to be 100% natural and safe, letting you confidently enjoy your lean reshaped figure worry-free. 
What Is Hourglass
Just like Leanbean, Hourglass is specially designed by one of the world's leading supplement companies - Propura - to meet the requirements of a female body. Both supplement formulas are fully transparent, contain vitamins, and both products are available from official websites only.
Hourglass is claimed to be a completely natural fat burner low in stimulants. Still, it contains caffeine from Guarana and tea, which may enhance your weight loss process when taken in moderate doses but may also cause jitters.  
Hourglass’s ingredients that trigger thermogenesis may help you reduce fat, speed up metabolism, and treat cellulite effectively, enabling you to get that hourglass shape for the coming summer.
But, according to many users’ reviews, it’s mainly focused on suppressing appetite.
Leanbean vs Hourglass: Common Ingredients
The following are fat-burning ingredients both these supplements contain. Some of them may not be the same but very similar.
Glucomannan is the key ingredient in both supplements. While Leanbean contains a good amount of it, the lower dosage in Hourglass seems to be insufficient for the best results.
B6 and B12 Vitamins
Both Leanbean and Hourglass formulas contain enough Vitamins B6 and B12 - essential for keeping normal energy levels, which enables you to fight cravings and fatigue.

The triggered thermogenesis  in combination with capsaicin (from cayenne pepper) and other similar ingredients like caffeine may suppress your appetite,  and bring about better fat loss results. 
Caffeine from green coffee in Leanbean and green tea extract in Hourglass also triggers thermogenesis effectively  , leading to faster fat burning , and enabling you to jump into that tiny bikini this summer and feeling proud of it.
Catechins and Chlorogenic Acid found in these ingredients are also powerful antioxidants.
Both Leanbean and Hourglass formulas contain certain unique ingredients. Let’s see which ones and compare their benefits.
Unique Leanbean Ingredients
A generous dose of Hydroxycitric Acid (HCA) found in the skin of Garcinia Cambogia fruit or tamarind is said to aid appetite suppression and weight loss. 
Some studies have shown that HCA stops an enzyme that turns sugar into fat.” Catherine Ulbricht, Pharmacist
Not only does it help to burn fat, but it also raises your serotonin levels making you feel happy and fit.
Curcumin extracted from this spice is another important natural Leanbean ingredient proven to burn calories and fat by slightly raising your temperature.  Plus, it can improve your immunity.
A low-carb diet and vigorous exercise regimen may lead to Zinc deficiency, which may further affect your blood glucose level, protein synthesis, carb, and fatty acid metabolism, among many other essential functions.

Besides antioxidants, this super fruit is abundant in dietary fiber, essential amino acids, vitamins, minerals, and other positive substances beneficial to your overall health.
Unique Hourglass Ingredients
Guarana is a widely-known, yet not sufficiently researched stimulant that is contained in the Hourglass fat burner. 
It boosts your energy mainly due to the combination of tannins, caffeine, and catechins - some of which are also thermogenic and promote weight reduction. Moreover, it’s believed to increase fat oxidation for enhanced fat loss.
Overdosing may make you feel anxious and jittery, and cause many other side effects, so be careful.
Caffeine and other compounds in energy drinks can boost heart rate and blood pressure. Caffeine can cause heart cells to release calcium, which may affect heartbeat, leading to arrhythmia. The drinks may also disrupt the normal balance of salts in the body, which has been linked to arrhythmia as well.

Among numerous other health benefits, this “sunshine vitamin” in Hourglass can help you lose a few pounds and fight depression  so that you always feel great in your perfectly shaped figure.
Studies show that people who lack this vitamin are prone to obesity, whereas women who take it with Calcium lose weight more easily. 
Side Effects Comparison
According to my findings, there are barely any side effects reported from Leanbean supplement users, whereas I couldn’t find enough evidence about any potential Hourglass side effects.
Since both fat burning products use optimal doses of natural ingredients, we may conclude that they’re safe in general.
However, I’d suggest that you always check the supplement labels to ensure they don’t include any ingredients you’re allergic or sensitive to.
Also, it would be wise not to take these fat loss pills at least several hours before going to bed, because you may find it hard to fall asleep due to the stimulants like caffeine from Guarana or green tea.Always be careful with caffeine because overdosing may cause headaches, heart palpitations, and other toxic or even fatal outcomes.  
Caffeine in weight-loss products and dietary supplements may be listed on the labels as guarana, kola nut, yerba mate, green tea extract, or green coffee bean extract.
National Institutes of Health
Neither Leanbean nor Hourglass fat burners are cheap, but they both appear to offer good value for the money.
Leanbean currently has 180 capsules capsules, which is enough for one month of use. Plus, it comes with generous discounts for bulk orders, free shipping to the USA and UK, money back guarantee, as well as a free home workout or healthy eating guide, depending on the package.
At the moment, Hourglass supplement costs much higher on a per bottle basis containing 90 capsules, i.e. 30-day supply, with free worldwide shipping.
LeanBean vs Hourglass: Who's the Winner?
With years on the market, both of these fat burners give great results and have been designed with women in mind.
But, based on my own experience, my friends’ comments, and many other Leanbean and Hourglass fat burner reviews which other users have shared, my recommendation goes to the Leanbean supplement.
Its formula may be more effective in fighting stubborn belly fat as it’s stronger yet unaggressive, and contains more natural ingredients without stimulants. 
What’s more, it seems safe with very few reported side effects, and is reasonably priced too.
