Invigor8 Fat Burner is made and sold by Biomedical Research Laboratories, LLC. It is a thermogenic fat burner that contains eight natural ingredients that work together to burn fat, suppress appetite and boost energy, mood & metabolism.

Natural fat burner with positive reviews, but questionable purchase process.

Product Details

Invigor8 Fat Burner is one of several products in BRL’s Invigor8 line. The supplement’s eight active ingredients are:

  • Bacopa leaf extract, also known as brahmi, may help reduce anxiety and increase attention to boost mood. Unfortunately, it also produces a wide variety of side effects.
  • Chrysin is said to prevent the natural conversion of testosterone to estrogen, thereby increasing testosterone levels and potentially supporting the creation/retention of lean muscle mass. However, research in humans has not supported this claim.
  • Forskolin rook extract comes from a tropical plant related to mint and it may help fat cells release stored energy, which translates to more fat (and inches) lost.
  • Garcinia fruit extract contains hydroxycitric acid (HCA), which is said to have a slimming effect. However, research shows that this substance has little-to-no effect on actual weight loss.
  • Green coffee bean extract is a significant source of caffeine. It improves mood and focus, plus boosts metabolism and helps control cravings.
  • Green tea leaf extract is a powerful antioxidant that may help boost both metabolism and increase rate of lipolysis (fat breakdown) in the body.
  • Olive leaf extract is an anti-inflammatory substance that supports proper thyroid functioning to promote weight loss.
  • Raspberry ketones reduce appetite and increase rate of fat burn.

All of these ingredients are contained in a single veggie (cellulose) capsule.

Invigor8 Fat Burner should be taken twice per day at least 30-45 minutes before meals. For the first three days, take just one capsule at a time. After you have assessed your tolerance to the supplement, increase dosage to 2 capsules twice a day. The pills‘ website notes that “accustomed users” may even choose to increase their daily dose to 6 capsules: 2 pills three times a day.

Invigor8 Fat Burner: Reviewed

Invigor8 Fat Burner has received dozens of positive reviews, but that doesn’t mean you jump on the bandwagon right away. Here are some important positive and negative qualities of this supplement:



The biggest strength of Invigor8 Fat Burner is that it has dozens of positive customer reviews. Granted, these testimonials may or may not be coming from real users (only a couple have pictures)… but still a positive sign. More than the positive reviews, however, we appreciate that Invigor8 products come with an impressive 90-day return policy. They will accept any order back for a refund for up to 3 months, even if you’ve already taken all of the capsules.

On the other hand, many of the ingredients in this supplement can cause unwanted side effects. Thankfully, in our research, these capsules do not typically cause negative side effects – except keeping people up if they take the pills too late in the day. In actual use, the more worrisome issue is that the typical user takes anywhere from 4-6 pills per day (which can be very inconvenient), and the site runs a subscription service. If you order directly from BRL, be careful not to sign-up for a subscription to the supplements before you’re sure you like them.

How Much Does Invigor8 Fat Burner Cost?

Invigor8 Fat Burner costs $49.95 per bottle. Each bottle contains 120 capsules, which is equivalent to a one-month supply since users take 4 capsules per day. This is slightly more expensive than the average fat burner, but manufacturers do offer a generous 90-day, money back guarantee.

Final Recommendation

Despite the sure benefits of Invigor8 Fat Burner, it did not top Healthtalk Daily’s list of best appetite suppressants this year. Instead, we recommend 5 Star Fat Burner to burn fat, shed inches and lose weight faster. Unlike Invigor8, 5 Star Fat Burner is easy to take and does not cause any unwanted side effects. More, the site that sells them ( has dozens of testimonials with pictures and does NOT have any sort of subscription service.
