RevBurn ReviewRevBurn is a fat burning supplement and thermogenic developed by Rev Labs. It has been formulated to increase energy and endurance, provide appetite suppression and control and support metabolic optimization.

Stimulants Are a Part of the Formula

One of the first aspects about this dietary supplement that you should know before you decide to purchase and try it is that RevBurn does contain more than one stimulant. Most notably it contains caffeine, phenylethylamine HCl and kola nut.

On the plus side, stimulants like caffeine are known to have an effect on the central nervous system. It is commonly believed that caffeine’s ability to elevate mood and metabolism could have a positive effect on individuals who are seeking to burn fat for weight loss.

For instance, one study suggests that when caffeine is ingested prior to aerobic exercise it can increase fat loss.

On the downside, there is no guarantee that ingesting caffeine, either via RevBurn or through other drinks or foods, will result in fat loss that will lead to measurable and long-term weight loss.  Additionally, caffeine and other stimulants can cause unwanted side effects, such as:

  • Jitters
  • Rapid heartbeat
  • Sleep disturbances
  • Anxiety
  • Headache

The suggested dosage is to take 1 capsule in the morning with 8-12 fluid ounces of water and to take 1 capsule in the afternoon or prior to your workout. Users should not have more than 2 capsules within a 24-hour period. Additionally, to decrease the potential risk of unwanted side effects, such as sleep disturbances, avoid taking these pills too late in the afternoon or the evening.

What Else to Consider

The makers of RevBurn say that when it is combined with exercise and a reduced calorie diet, it can help a user reach their weight loss goals as the ingredients within the formula can boost metabolism and fat-burning for up to 8 hours.

There is no clinical proof that this claim is true. Moreover, you should not assume that simply because this is a nonprescription weight loss aid that it is safe to take. If you have an existing medical condition, are taking prescription or over the counter medications or herbal supplements to treat a health issue, or are pregnant or nursing, you should consult with your doctor before taking RevBurn diet pills.

Xenadrine Ultimate

Xenadrine Ultimate ReviewXenadrine Ultimate is a dietary supplement designed for weight management support. It promises powerful weight loss and claims to deliver on this promise with a formula containing ingredients that have been scientifically researched. Its primary function is to boost metabolism and help keep you energized.

Xenadrine Ultimate is composed of two different complexes. There is a Weight Loss and Metabolic Intensity Complex (Robusta Coffee Bean, Caffeine Anhydrous, Yohimbe Bark), and a Xenadrine Ultimate Complex (Garcinia fruit, L-theanine, Spearmint Leaf, Autumn Olive Fruit, Ashwagandha Root and Leaf).

The key ingredients in Xenadrine Ultimate are believed to be ideal for weight loss and each has been scientifically researched. For instance, studies have found that green coffee bean (robusta coffee bean) may be an effective fat burner and energy booster. Garcinia cambogia may help with fat burning, appetite suppression and fat blocking. Caffeine may help with appetite suppression, boost mental alertness and can maximize fat burning when combined with physical activity. Ashwagandha is believed to help decrease the stress hormone, which can help prevent emotional weight gain. Spearmint leaf aids in digestion.

Although the official product page for Xenadrine Ultimate does provide links to studies for some of the ingredients it uses in its formula, be advised that none of them have ever been clinically proven effective for producing measurable weight loss.

There is 200 mg of caffeine per serving (2 capsules). Therefore, the full recommended dose will mean you are ingesting 400 mg of caffeine per day, which is slightly more than 4 regular mugs of coffee per day. This much caffeine can lead to an increased risk of unwanted side effects, especially if other caffeine or stimulants are ingested while taking this product. These effects may include: insomnia, sleep disturbances, restlessness, anxiety, rapid heartbeat, headache, etc.

For best results, take two capsules twice per day, 30 to 60 minutes before your two main meals. Use for 60 days with exercise and diet and stay hydrated by drinking 8 to 10 glasses of water daily. Avoid snacking between meals and don’t take the pills within 5 hours of bedtime.

That being said, it is recommended that you first assess your tolerance with Xenadrine Ultimate. For the first 3 days you start taking the pills, only take 1 capsule twice per day, 30 to 60 minutes before your main meals. From day 4 and onwards, if you are tolerating the dose well, you can up it to 2 pills, twice per day.

Prior to taking Xenadrine Ultimate, consider speaking with your healthcare provider. This is particularly prudent if you have an existing medical condition or are currently taking medications.
