Product description

Thermogenesis: The Science Behind Fat Burning

It’s a generally accepted theory that energy cannot be created or destroyed, but it can change form — and that’s true for the human body, too. Energy enters our bodies through the food we eat; the amount of energy contained in food is measured in calories. As we eat, those calories are either converted for use or stored, often as fat.



Thermogenesis literally means “production of heat.” When metabolic rates rise, energy increases and releases stored fat. This release of fatty acids further generates heat to burn fat cells and convert calories. NatureWise Thermo Blend includes ingredients formulated to increase metabolism and energy, promote fat burning, and support weight loss.*

Natural Energy Without Added Caffeine

For high intensity workouts, some studies suggest that thermogenics may improve muscle endurance and aerobic exercise performance.* However, many products that promise a boost in energy can contain large amounts of synthetic caffeine anhydrous. .



Caffeine anhydrous is generally considered safe in small doses, but people may experience negative effects with larger doses, such as anxiety, dry mouth, gastrointestinal discomfort, and muscle twitches.



NatureWise ThermoBlend contains only naturally occurring caffeine, provided by the ingredients green tea extract, guarana seed extract, and cocoa; and synephrine, from bitter orange. These stimulating ingredients are all natural and research supports their thermogenic properties.* We do not add manufactured caffeine anhydrous to our formula.

User questions & answers

Question:	How many kilos should i expect to lose aproximately in 1 month if i exercise regularly and control my diet? Can i lose like 4 kilos or less
Answer:	The answer depends on how much excess body weight you are carrying. Someone 100 lbs overweight would lose probably 20-25 lbs while someone 30lbs overweight would probably lose only 8-15. 85% of weight loss is diet. If you changed your diet completely and did som cardio, you would see more benefits versus someone who did cardio 6 days a week and didn't really change their diet. Pills are always a great supplement to a clean diet and exercise, but pills alone rarely yield great results.
Question:	The product description states that the supplement contains Ashwaghanda. The ingredients list does not include this ingredient. which is it
Answer:	I am looking at my bottle now, and it does include Ashwagandha. Specifically, it reads, "Ashwagandha Extract (Withania somnifera) (root) (1.5% withanolides) 50mg"
Question:	Where are the ingredients from? label only claims it was bottled in the usa
Answer:	We appreciate your question. All our supplements are manufactured in the United States.

Answer:	Thank you for reaching out. Yes, our Thermo Boost is Non-GMO, vegan & gluten free.

Turn Up the Heat & Boost Your Burn

Thermogenesis is the body’s process of burning calories to produce heat. This raises your metabolic rate & prompts your body to burn stored reserves for energy. Thermogenesis happens naturally when you exercise, & is one of the reasons that exercise promotes the reduction of body weight. But the more you work out & lose weight, the more efficient your body becomes at converting calories into energy, until eventually your weight reaches a plateau.

NatureWise ThermoSparkcontains plant extracts, herbs & nutrients selected to support the metabolism & and promote thermogenesis. It includes natural ingredients like Green Tea, Guarana, Yerba Mate, Rhodiola, Cayenne, & Kola Nut, plus Advantra Z, a patented bitter orange extract that’s proven to boost metabolism & encourage a healthy weight when combined with a nutritious diet & exercise.*

Clinically Researched Extract

Advantra Z is an extract of bitter orange, which is high in naturally-occuring p-synephrine, a non-stimulating metabolic enhancer. It’s clinically researched to positively affect the metabolic rate and support healthy weight maintenance without negatively affecting blood pressure or heart rate.*

Natural Thermogenics

Stimulant herbs like Green Tea, Guarana, Kola, and Yerba Mate are high in naturally-occurring caffeine, which promotes energy production and metabolic activity without the jittery effects of artificial caffeine. Cayenne pepper is high in capsaicin, another thermogenic ingredient.*

Energizing Adaptogens

Ashwagandha and Rhodiola are adaptogenic herbs that support energy and metabolic health through the endocrine system by promoting thyroid function and supporting the adrenals. They also support the body’s resistance to stress, encouraging the reduction of cortisol levels.*

Antioxidant Power

Potent antioxidants in Green Tea, Yerba Mate, Olive Leaf, Ashwagandha, and Rhodiola may help to neutralize free radicals and eliminate toxins that are released during exercise and can lead to muscle fatigue.*
