Ranking The Best Supplements To Boost Metabolism

Why We Like Provitalize

Many women over 40 experience menopause symptoms due to a decline in estrogen levels. Unfortunately, menopause very often leads to a slower and more sluggish metabolism. 

The result is usually higher fat concentration in the belly, around the liver and abdomen, lower energy levels, chronic fatigue, brain fog, mood swings, and dry skin.

Provitalize contains two metabolism-boosting probiotic strains – B. Breve IDCC4401 and B. Lactis R101-8 designed to holistically address the root cause of a sluggish metabolism.  

The probiotics ensure the healthy growth of good bacteria in the gut. They also promote optimal balance of the flora in the intestinal walls. Finally, emerging research indicates they may also support healthier blood sugar and cholesterol levels. effective regulation of blood sugar levels and elimination of bad cholesterol. 

As a result, the supplement compensates for the body’s aging and slowing metabolism, helping you to lose weight, boost energy levels, concentrate better, and reduce mood swings. Other than those specific metabolic benefits, the vitamins and minerals contained in the natural compounds of the formula can also improve your general well-being by compensating for any deficiencies. 

Key Ingredients and Benefits 

  1. B. Breve IDCC 4404 – The compound was found to improve cholesterol metabolism. Furthermore, B. Breve IDCC4401 also lowered total cholesterol and LDL (low-density lipoprotein) cholesterol levels [1].
  2. B. Lactis R101-8  – Regular consumption has improved saturated fat metabolism in two studies. Other studies show benefits for managing key inflammation markers that could otherwise slow your metabolism if left unchecked [2].
  3. L. Gasseri SBT2055 – In two clinical trials, participants saw a reduction in abdominal visceral fats (belly fats) by up to 4.6%17 and 8.5%18, respectively. More importantly, L. Gasseri SBT2055 works naturally by blocking fat absorption and promoting fat excretion through the feces, helping your body use stored fat as a primary energy source [3].
  4. Phytoestrogens – Provitalize contains both curcumin (turmeric) and moringa leaves, which have anti-inflammatory properties. They have also been shown to promote greater hormonal balance by alleviating symptoms of estrogen decline [4]
  5. BioPerine® (black pepper extract) and Sunflower lecithin – Both active compounds have been shown to enhance the absorption of vitamins, minerals, and other beneficial properties of herbal formulas, further magnifying the benefits of other ingredients [5].

Why We Like the Slim Gut Bundle

If you need a quicker way to see visible results, then the Slim Gut Bundle is your best option. This holistic bundle combines the weight-management powers of Provitalize with ‘super fiber’ prebiotics in Previtalize.

The probiotics in Provitalize feed on these ‘super fibers’ to multiply faster and survive longer in the gut. This means women can see faster visible results, such as a boost in metabolism and reduced belly fat and cravings.

Key Ingredients and Benefits

  1. Healthy fibers – The bundle contains fructooligosaccharides (FOS), galactooligosaccharides (GOS), and inulin. They can help normalize bowel movements, aid digestion, balance blood sugar levels, reduce cholesterol, and boost metabolism [6] [7].
  2. Metabolism-friendly probiotics – The aforementioned L.Gasseri (SBT 2055), B.Breve (IDCC 4401), and B.Lactis (R101-8) are all part of the formula, helping to support the management of abdominal fats, increase insulin sensitivity, and improve bacteria balance in the gut. 
  3. Burdock Root – This is a natural compound used for hundreds of years to reduce inflammation without the possible side effects of mainstream medications. More specifically, it can address joint aches, dry skin, and the higher concentration of toxins in your blood due to a sluggish metabolism [9].

Why We Like Night Shred

Declining estrogen levels and disruptions in hormonal balance due to menopause can cause significant disruptions in how much you sleep and the quality of your resting time. 

During your sleep, your body burns significant amounts of energy to prepare you for the day ahead, so higher sleep quality directly correlates with greater weight loss

Night Shred’s unique formula specializes in improving sleep quality through a natural holistic approach, targeting common vitamin and mineral deficiencies and physiological systems crucial for healthy sleep. If you want to hit two rabbits with one stone, this supplement can be an excellent way to improve sleep quality and boost your metabolism. 

Key Ingredients and Benefits

The powerful blend of herbs and natural compounds contains powerful antioxidants, which can help you calm down, reduce muscle tension, manage anxiety, and fall asleep more quickly.  
  2. Fat-burning compounds – The formula contains 81mg of Grains of Paradise Seed Extract, CLA, and L-carnitine tartrate, all of which work on different pathways to increase thermogenesis, boost your metabolism, increase energy levels, and encourage the breakdown of fat as a primary source of energy. 
  3. Ashwagandha Root Extract – If your body is stuck in a perpetual ‘fight or flight’ response due to the chronically stressed reality of modern life, it’s tough to fall asleep or get deep rest without waking up. The natural herb has adaptogenic properties, which help reduce anxiety and stress management, helping you sleep better and reduce inflammation due to lower cortisol levels [10].
  4. Magnesium Oxide – Magnesium is one of the most crucial minerals necessary for optimal energy production in more than 300 biological processes within the body.

Why We Like Hydroxycut

Hydroxycut is a popular metabolism-boosting and weight-loss supplement with 5,000+ Amazon reviews and a solid 4-star rating on Amazon. The formula contains many of the most popular natural ingredients in other formulas, along with a few vitamins and minerals relevant to an optimal metabolic rate. 

If you are just starting out and seeking a straightforward metabolism booster, Hydroxycut is a solid choice. However, its metabolism-boosting properties are not as comprehensive and holistic as the other supplements on the list. 

Key Ingredients and Benefits

  1. Hydroxycut Complex – Hydroxycut contains a 604mg proprietary formula called Hydroxycut Complex, made of 200mg of Robusta coffee extract, 100mg of apple cider vinegar, and 204mg of coffee extract. The combined effect seeks to improve energy levels, boost thermogenesis, and increase cognitive function, helping you to build and maintain healthy habits.
  2. Essential vitamins Although the formula also contains vitamins like D and B, they will be helpful only if your current diet is lackluster and you need a way to compensate for a severe deficiency.

How to Choose The Best Metabolism Booster for Your Needs

Check for Third-Party Certification

As supplements can be sold without approval by the FDA, reliable supplement manufacturers get third-party certifications to distinguish their products as trustworthy. 

These certifications verify the ingredients and quantities claimed on the product label and that the product meets stringent manufacturing and performance standards. Established certifications to look out for include GMP, USP, NSF, Certified Organic, Non-GMO certified, etc.

All supplements made in the USA are under FDA regulation. The same applies to Canada and Australia. Ensure products you buy come from FDA/TGA-registered facilities using GMP-certified manufacturing processes. Many supplements, especially those purchased on eBay and Amazon, are manufactured abroad with little regulation.

Read The Ingredient Label

Look for science-based ingredients that can be easily absorbed by the body and come with a sufficiently high dosage to give health benefits. 

When it comes to the science behind natural compounds and healthy ingredients, always look at the research. Clinical trials help substantiate the efficacy of ingredients through proper tests. Look for a supplement with clinically tested ingredients for real benefits, and avoid those based on anecdotal evidence. It is even better if multiple studies are backing the product.

Furthermore, research not only the data behind an ingredient but also its ability to be effectively absorbed by the body. 

Supplements that the body can’t absorb are essentially ineffective. Your selection process should consider supplements with ingredients that enhance absorption. Also, look for high-quality capsules that break down at the right time for nutrients to be fully absorbed.

Examine the Refund Policy

A risk-free guarantee lets you try supplements without fear of losing money. If you try the product and don’t experience results, simply contact the manufacturer for a refund. A 60- or 90-day guarantee is the minimum a manufacturer should have as a show of confidence in their products. 

Also, avoid companies that make you jump through hoops. One common strategy companies use is “bottle return” – they require you to pay for return shipping and return the empty bottles before processing your refund.

How to Increase Your Metabolism

Nutritional Supplements Can Help With Belly Fat Loss

Nutritional supplements are the answer if you are wondering how to boost your metabolism without risking your health. 

They are made from safe and healthy ingredients, formulated to supply nutrients and other beneficial ingredients to the body in a natural and non-invasive way. 

Some nutritional supplements are designed with natural ingredients that boost metabolism and support your weight management efforts over time by targeting the root cause. The right combination of ingredients can help women naturally curb appetite, enhance metabolism, and prevent fat absorption.

This approach means it can take time for most women to experience results (typically 60-180 days). However, it doesn’t require extreme diets or excessive exercise, doesn’t risk your health due to unexpected side effects and health hazards, and can be sustainably used over the long term because the natural compounds are easily absorbable and utilized by the body. 

There are multiple categories of nutritional supplements with metabolism-boosting properties. Some of the most common ones include:

  1. Probiotics with metabolism-boosting effects – Choose specific strains with “thermogenic” properties that are clinically proven to increase metabolism, prevent fat absorption, and decrease abdominal fat by strengthening gut health, boosting microbial diversity, and lowering inflammation. Examples include B. breve IDCC4401, B. lactis R101-8, and L. curvatus HY7601 with L. plantarum KY1032.
  2. Fat absorption inhibitors – These ingredients, like chitosan and garcinia cambogia, naturally block fat from being absorbed from your diet or prevent storage. Unlike prescription-strength fat blockers that can cause digestive issues, these natural ingredients are gentler. They either bind to fat molecules or intercept the fat formation process. However, research on long-term effects remains inconclusive.
  3. Metabolism stimulants – The most common supplements contain green tea, coffee extract, capsaicin, and other compounds. These ingredients stimulate or support fat breakdown into energy – especially useful for women who experience low metabolism and fatigue. Just note that stimulants should not be consumed excessively, or you may risk heart palpitations, high blood pressure, and anxiety.

Weight loss medications have been clinically tested to reduce weight. Drug trials show participants can lose up to 5 – 15% of their body weight.

However, these aren’t for just anyone to take. Most physicians only prescribe them when someone has a body mass index (BMI) of 30 and greater or a BMI of 25 – 30 with a weight-related illness like type 2 diabetes, high cholesterol, or high blood pressure.

A big drawback of pharmaceutical fat metabolism boosters is they sometimes don’t resolve the root cause of the over-40s weight gain – such as hormonal cravings and sluggish metabolism. Left unchecked, the problem may worsen.

As with most prescription drugs, the side effects may make you wonder if it’s worth the risk. These include serious health issues like pancreatitis, seizures, heart palpitations, chest pain, insomnia, vomiting, uncontrolled bowel movements, and suicidal thoughts [11].

Increasing exercise frequency and adding muscle-strengthening activities is a great way to burn more calories during the activity and increase thermogenesis in your everyday life due to your higher muscle mass. 

It’s especially important to do some form of strength training specifically because menopause symptoms can also include the loss of muscle mass as you get older (muscle atrophy).

Experts like Dr. Axe suggest that strength training – such as lifting weights- can help improve metabolism because it builds lean muscle mass, which naturally uses more calories than body fat.

Working out alone is not sufficient to keep your metabolism in the healthy range. It must be combined with a healthy diet, a low-stress environment, an active lifestyle, and sufficient deep and restful sleep. In particular, metabolism boosters can be an excellent way to get an extra push and receive more motivation and energy to sustain those healthy habits.

The best diet for a metabolism-friendly lifestyle should be financially feasible, and sustainable over the long-term, compatible with your genetics and pre-existing conditions, and sufficient to offer you a balanced amount of every essential macronutrient (carbs, protein, and healthy fats), vitamins, and minerals. 

Experts like Dr. Axe recommend choosing a diet based on nutrient density and ensuring you eat the foods needed to provide you with the necessary nutrients instead of counting calories. However, instead of obsessing over calories, you can still count the rough amount you eat to ensure you are not in a severe caloric deficit (400 calories or more below the daily requirement for your unique needs).

Being in a caloric deficit can be healthy if it’s small, which can gradually lead to weight loss. But, if it’s a severe caloric restriction, you are not getting enough essential nutrients necessary for a quick metabolism, and your body is likely to shut down and slow your metabolism to preserve energy as a protective mechanism from starvation.

Frequently Asked Questions

You can expect to lose between 5% to 10% of your body weight if you consistently use the supplement according to the instructions and other healthy habits, like eating well, exercising regularly, and sleeping enough.

Combined with a good diet and regular exercise, the right supplement can enhance your efforts to eliminate stubborn belly fat. One study published in the peer-reviewed British Journal of Nutrition found that participants consuming Lactobacillus gasseri SBT2055 reduced abdominal fat  (visceral fat) by up to 8.5% over 12 weeks [13].

Yes, all belly fat burners listed above are safe because they are manufactured in regulated facilities, have transparent formulas, and contain only natural and clinically tested ingredients.

A study published in Today’s Annals of Internal Medicine suggests eating 30 grams of fiber daily can help you lose weight. Prebiotic fibers have also been shown to ease cravings, balance moods, and enhance the effects of probiotics [14].

Final Thoughts

Boosting metabolism is complex, and while there are FDA-proven pharmaceutical solutions, these solutions may carry adverse side effects or be aggressive.

On the other hand, building muscle, establishing an effective sleeping schedule, and staying on top of your diet requires much effort and time to master.

Metabolism boosters can be an excellent way to get an accessible and easy-to-use way of optimizing your metabolic rate, boosting energy levels, and alleviating menopause symptoms. However, those supplements are not a one-size-fits-all solution and shouldn’t come at the expense of building healthy habits.
