Thermogenics are a class of supplements that encourage your body to produce heat. Typically, these products do so by increasing your metabolic rate, causing the body to burn more calories. These kind of supplements are plentiful enough that you can cycle through a number of different products. Rotating thermogenics in this way can help you stave off any built-up tolerance. Consult a physician for guidance when using thermogenic products.
Ask your doctor if using thermogenics is appropriate for you. Bring specific products you are considering using to a doctor visit, so your doctor can assess suggested dosing and ingredients. The U.S. Food and Drug Administration doesn't examine dietary supplements for safety prior to their release to the market; your doctor can help identify potential health risks. Some thermogenics such as ephedra, have been banned by the FDA after harmful effects in users were documented.
Compare the active ingredients of the thermogenics you plan to use. While caffeine is a common ingredient in these products, some products feature other stimulants and purported fat-burning ingredients as the primary ingredients. Note the similarities and differences in ingredient contents and amounts.
Decide how long you want to be cycling thermogenics and how long you want to use each product. Creating this time frame will drive your decisions on how much of each product you should buy and will allow you to plan around any events in your life, such as bodybuilding competitions or vacations. Check with your doctor once you have developed your time frame to gain insight into whether your plan is safe.
Organize your thermogenics into a cycling order. Try to space out products that have very similar ingredient contents, as using two like products in a row may lead you to build a tolerance to the common ingredients. Cycling will work best if the sequence of products you use reduces the likelihood of building a tolerance. Consider how long the manufacturers recommend using their products when deciding on placement of products in your schedule. Including a short break between the use of each product may help reduce your likelihood of building a tolerance.
