Description
Peak Performance Slimferno – Grapefruit-Lemon
With a unique blend of carefully selected ingredients and a fresh grapefruit-lemon flavour, this 240 gram jar offers a convenient way to integrate active components into your daily routine.
Active Ingredients & Science
This process is especially important during physical activity when the body needs to mobilise energy reserves efficiently. The tartrate form is chosen for its stability and bioavailability, meaning the body can absorb and utilise the ingredient more effectively than other forms.
Sinetrol® XPUR – Plant-Based Energy and Antioxidants
Sinetrol® XPUR is a patented blend of citrus fruits and plant extracts combining grapefruit, sweet orange, guarana, blood orange, and bioflavonoids. This ingredient is particularly notable for its content of natural bioflavonoids – polyphenolic compounds found in citrus fruits known for their antioxidant properties. Blood orange adds additional antioxidants and a unique flavour profile. The combination of these ingredients creates a synergistic effect where the different plant components work together to support the body's natural processes. The bioflavonoids are especially valuable as they can be absorbed alongside vitamin C, enhancing their biological effectiveness.
Taurine – Cellular Function and Muscle Support
Taurine is a conditionally essential amino acid naturally produced in the body but often added to performance products to support specific functions. During intense exercise, taurine concentrations in muscles may decrease, making supplementation particularly relevant for athletes.
L-tyrosine – Cognitive Function and Stress Management
L-tyrosine is an amino acid that serves as a precursor to several important neurotransmitters, including dopamine, noradrenaline, and adrenaline. These neurotransmitters are critical for mental focus, motivation, and attention – all factors important during both exercise and daily activities. During periods of stress or intense mental effort, the body's tyrosine reserves can become depleted, potentially affecting cognitive performance. This makes the ingredient particularly valuable for those combining physical training with mental demands.
Caffeine – Energy and Mental Alertness
Caffeine is a well-established ingredient that acts as a central nervous system stimulant. In Slimferno, caffeine comes from two sources: directly added caffeine and from guarana in the Sinetrol® XPUR blend, creating a gradual and sustained energy effect rather than a rapid peak followed by a crash.
Green Tea Leaf Extract – Antioxidants and Metabolic Support
Green tea leaf extract is rich in catechins, a type of polyphenol with powerful antioxidant properties. The most studied catechin in green tea is EGCG (epigallocatechin gallate), known for its ability to support the body's natural metabolic processes. The combination of green tea leaf extract with caffeine is particularly interesting as these two ingredients have been shown to work synergistically to support focus and energy.
Panax Ginseng Extract – Adaptogen and Energy Support
Panax ginseng, often called Asian ginseng, is a classic adaptogen used in traditional medicine for centuries. Ginseng contains ginsenosides, active compounds that can support energy levels, mental clarity, and physical performance.
Choline Bitartrate – Cognitive Support and Cellular Function
Choline is an essential nutrient important for several bodily functions, including brain function and muscle control. It is a precursor to acetylcholine, a neurotransmitter critical for memory, focus, and muscle contractions. Choline bitartrate is a stable form of choline that can be effectively absorbed by the body. For athletes, adequate choline intake can support both mental performance and muscle contraction during exercise.
Vitamin C (L-ascorbic acid) – Antioxidant Protection
Vitamin C is a water-soluble vitamin and a powerful antioxidant that plays many important roles in the body.
Chromium (III) – Nutrient Metabolism
Chromium is a trace element involved in carbohydrate and fat metabolism. It can support normal blood glucose levels and may influence how the body utilises nutrients for energy. Chromium (III) is the biologically active form of this mineral and is often included in performance products for its support of metabolic function.
Inositol – Cellular Signalling
Inositol is a natural compound involved in cellular signalling and can affect several metabolic processes. It is a component of phospholipids, which are important for the structure and function of cell membranes.
Raspberry Extract – Antioxidant and Flavour Component
Raspberry extract adds both flavour and antioxidant compounds to the formula. Raspberries contain ellagic acid and other polyphenolic compounds that can support the body's natural antioxidant defences.
Benefits & Uses
Energy and Mental Focus During Training
The combination of caffeine from both directly added caffeine and guarana in Sinetrol® XPUR creates a dual-action energy effect.
L-carnitine tartrate plays a central role in this formula by supporting the body's ability to mobilise and utilise energy reserves efficiently.
Antioxidant Protection During and After Exercise
Intense exercise generates oxidative stress in the body as muscles work hard and consume oxygen. Slimferno contains several antioxidant ingredients: vitamin C, bioflavonoids from Sinetrol® XPUR, catechins from green tea leaf extract, and ellagic acid from raspberry extract. Together, these ingredients create a comprehensive antioxidant defence that can help neutralise free radicals and support the body's natural recovery processes.
Support for Muscle Contractions and Cellular Function
Taurine, choline, and L-tyrosine work together to support muscle contraction and cellular function.
Adaptive Stress Management and Recovery
Panax ginseng extract acts as an adaptogen that can help the body manage both physical and mental stress.
Daily Energy and Mental Performance
The combination of caffeine, L-tyrosine, panax ginseng, and green tea leaf extract can support mental focus, motivation, and attention during work, study, or other mentally demanding activities. The fresh grapefruit-lemon flavour also makes it a pleasant way to get this energy.
