True Grit THERMO’s Ingredients

True GRIT Thermo

Can the new Ophiopogon extract make a difference? We hope so!

True Grit’s commitment to fully disclosed and non-proprietary labels means it’s easy to get into the “scientifically-dosed” ingredients, and see if THERMO lives up to its billing.  Will it take 1, 2, 3, or heaven-forbid 4 pills to get rid of that unwanted fat?

Just like with all of their other supplements, True Grit is bringing a new ingredient to the party, so let’s start our diagnosis there:

  • Ophiopogon Extract root (25mg)

    This extract comes from the root of the Ophiopogon japonicus tree and is also known as Dragon’s Beard.  It is traditionally used in Chinese Medicine to treat inflammation and cardiovascular complications.[1]

    You may be asking, “why is this included in a thermogenic then?”  Well, according to a 2013 study, orally supplementing with Ophiopogon Extract for 2 weeks resulted in weight loss and a decrease in the amount of adipose tissue (fat mass) in the obese.[2]

    What about the dosage?

    According to the study, the subjects received a pretty hefty dose of 300mg/kg of bodyweight to elicit the fat loss aspects of Ophiopogon Extract. There’s only 25mg contained in THERMO, so we’re not sure if that will correlate (it’s tough to draw conclusions on weight loss from rat studies anyway).

    Still, it is refreshing to see supplement industry continue to innovate by bringing newer ingredients into their products and not just rehashing the same ol’, same ol’ stuff with a shiny new label.

  • Caffeine (270mg)

    True Grit THERMO Ingredients

    The ingredients / supplement facts label

    No pre-workout, thermogenic, or any other supplement worth its salt is complete without a hefty dose of caffeine and THERMO does not disappoint.  Next to creatine, caffeine is the most researched supplement out there and has been shown repeatedly to be effective for fat loss, focus, energy, and mood improvement.[3,4,5,6]

    We won’t waste time explaining all the great benefits of caffeine as you are well aware of them, we’ll save the explaining for some of the other less publicized ingredients.

    Note that 270mg is from two capsules.

    This is an “above average” dose of caffeine, and seems to be what most users want. However, if you’re stimulant sensitive, you definitely want to start with one capsule.

  • Garcinia Extract (200mg)

    Harvested from the small Southeast Asian fruit, garcinia cambogia, Garcinia Extract is rich in hydroxycitric acid.  As you can see from the label above, True Grit’s THERMO has standardized 60% hydroxycitric acid.

    Garcinia extract works by inhibiting the enzyme that is required to synthesize fatty acids by the body, aka de novo lipogenesis. Additionally, various studies have noted positive effects in relation to appetite suppression and weight loss.[7]

    However, those studies have various confounding variables which negate the validity of Garcinia Extract as a viable weight loss supplement.  Based on the most current research, Garcinia has not been shown to be effective for losing fat in humans.[8,9]

  • Green Coffee Bean Extract (200mg)

    No other supplement in 2014 caught fire, and then came under that same fire, more than Green Coffee Bean Extract (GCBE).  Touted by the media and Dr. Oz as the next miracle weight loss ingredient, countless supplements were made including this ingredient based off a now retracted study.[10]

    Various studies have been conducted with dosages over 2x as much as is present in THERMO with no proof of weight loss.[11]  That’s not to say that GCBE is without merit as it has demonstrated the capability to help in lower blood pressure.

    More than likely, this was included to help with marketing the product and grab the attention of the Dr. Oz brigade.  We’d prefer to see companies putting truly “research-backed” ingredients in their formulas and not marketing ingredients that have since been shown to not work.

  • Coleus Forskohlii Extract (100mg)

    Used in Ayurvetic medicine, Coleus Extract (Forskolin) is an herb that has been shown to increase cAMP (cyclic adenosine monophosphate) levels in the body’s cells.  Why does this matter you ask?

    Well, increasing cAMP elicits similar benefits as exercise does in regards to mitochondrial enzyme activity in the body.[12]  This can lead to enhanced muscle protein synthesis in the body…GOOD STUFF!!!

    Additionally, Forskolin works synergistically with caffeine and seems to improve lipid (fat) metabolism through the same cAMP pathways discussed above.[13]

  • Green Tea Extract (100 mg)

    Green Tea contains a number of catechins and the most potent of those is EGCG, the form contained in THERMO.  EGCG’s benefits are well known in the areas of weight loss, antioxidants, and alertness.  We won’t waste anymore of your time expounding the claims of this as you have probably heard it a hundred time before.

  • Yohimbe Extract (12.5mg)

    Yohimbe is a naturally occurring alkaloid derived from the Pausinystalia yohimbe tree and the Rauwolfia Serpentina plant.  Yohimbe’s numerous benefits include:

    • Weight loss[14]
    • Appetite Suppression[15]
    • Enhanced Focus & Cognition[16]
  • Bioperine® (5.3mg)

    Bioperine is a patented form of piperine extracted from black pepper seeds.  It’s been known to increase the bioavailability of various minerals and nutrients and should aid in the absorption of these compounds.

True GRIT Fat Burner

What’s your Gritness?

Recommended Dosage for True GRIT Thermo

As with all stimulant based products, dosage will depend on each individual’s tolerance and reaction to the ingredients contained in this formula. If you don’t know how caffeine affects you, definitely start with 1 capsule and assess for a couple of days.

It is advised to take 2 caps 30-60 minutes before each of your 2 largest meals during the day.  As there are a number of stimulants contained in THERMO, it is best to avoid consuming it at least 5 hours prior to bedtime.

Final Thoughts

As our initial assessment shows, there is a hodgepodge of effective and not so effective ingredients contained in True Grit’s THERMO. We get it – there’s a marketing purpose to it, and far too many people are still searching for green coffee bean. But what we need to see when that happens are some effective ingredients. Thankfully here, that’s exactly what we get, and possibly more.

So that being said, it is refreshing to see a supplement company take a step forward and bring a newer ingredient to the party to see how it works.

While all the ingredients contained in THERMO aren’t “research-backed” to show effectiveness, it does show some promise to be a worthwhile thermogenic fat burner should you be in the market for something new.
