Reta3

Product Overview of Reta3

Reta3 is a dietary supplement in capsule form. It combines plant extracts, amino acids and essential minerals. It is intended to support weight balance, appetite control, metabolism and healthy blood sugar regulation as part of a calorie-controlled diet.

The product is made by Reta3. Each daily capsule contains seven active ingredients: guarana extract, apple cider vinegar extract, Jerusalem artichoke inulin powder, L-glutamine, L-leucine, zinc citrate and chromium picolinate. The amounts of each ingredient are listed in the composition table below.

The formula works on several fronts at once. Guarana provides natural caffeine, which is associated with thermogenesis and energy. Apple cider vinegar contains acetic acid, which may slow gastric emptying and moderate the rise in blood glucose after a meal. Inulin is a soluble fibre that swells in the stomach and may increase the feeling of fullness. Chromium and zinc contribute to the normal metabolism of macronutrients.

Reta3 is a food supplement, not a medicine. It is not a substitute for a varied and balanced diet or a healthy lifestyle, and it is not intended to diagnose, treat or prevent any condition. Anyone with a medical condition or taking medication should speak to a doctor or pharmacist before use.

Listed Ingredients in Reta3

Ingredient	Dosage	Role
Guarana Extract (Paullinia cupana)	100 mg	Rich in natural caffeine; stimulates thermogenesis and lipolysis (fat breakdown); boosts metabolic rate and physical energy; supports mental alertness and reduces perceived fatigue during calorie restriction
Apple Cider Vinegar Extract	100 mg	Contains acetic acid, which slows gastric emptying and blunts post-meal blood glucose spikes; promotes satiety; supports healthy digestion and may help reduce overall calorie intake
Jerusalem Artichoke Inulin Powder	100 mg	Soluble prebiotic fibre that swells in the stomach to increase feelings of fullness; ferments in the colon to feed beneficial gut bacteria, supporting digestive health and regularity; helps moderate appetite
L-Glutamine	50 mg	Conditionally essential amino acid supporting intestinal mucosa integrity and gut barrier function; may help reduce sugar and carbohydrate cravings; supports muscle recovery during calorie-controlled diets
L-Leucine	50 mg	Branched-chain amino acid (BCAA) that activates the mTOR pathway to stimulate muscle protein synthesis; helps preserve lean muscle mass during weight loss; supports stable energy metabolism
Zinc (Citrate)	15 mg	Essential trace mineral and cofactor for over 300 enzymes; contributes to normal macronutrient metabolism (carbohydrates, fats, proteins); supports normal fertility, immune function and protein synthesis; contributes to normal cognitive function
Chromium (Picolinate)	40 mcg	Enhances insulin sensitivity and receptor binding; contributes to normal macronutrient metabolism and maintenance of normal blood glucose levels; may help reduce sugar cravings linked to glycaemic fluctuations

Reported Benefits

Reta3 is intended to support natural weight balance and body composition management. It is designed for use alongside a controlled diet, not as a stand-alone solution. The formula combines several ingredients that act on appetite, metabolism and blood sugar.

Appetite and cravings are addressed through fibre and amino acids. Jerusalem artichoke inulin is a soluble prebiotic fibre that swells in the stomach and may increase the feeling of fullness. L-glutamine may help reduce sugar and carbohydrate cravings, and chromium may help limit cravings linked to glycaemic fluctuations.

Metabolism and energy are supported by guarana. Its natural caffeine content is associated with thermogenesis, the production of heat from calories, and with lipolysis, the breakdown of fat. Guarana may also support mental alertness and reduce perceived fatigue during calorie restriction, with a lighter stimulant load than some larger-dose products.

Blood sugar support comes mainly from apple cider vinegar and chromium. Acetic acid in the vinegar may slow gastric emptying and soften the rise in glucose after a meal. Chromium contributes to the maintenance of normal blood glucose levels, and zinc and chromium together contribute to normal macronutrient metabolism.

Finally, L-leucine is a branched-chain amino acid that stimulates muscle protein synthesis and may help preserve lean muscle mass during a calorie-controlled diet. Inulin also feeds beneficial gut bacteria, supporting digestive health and regularity, while L-glutamine supports gut barrier integrity. Zinc further contributes to normal immune function and cognitive performance.

Known Side Effects

Reta3 is generally well tolerated when used as directed. Dry mouth has been reported rarely, affecting up to 1 in 1,000 users. It is usually mild and short-lived.

Because the formula contains inulin fibre, some people notice mild digestive discomfort such as bloating or gas during the first days of use. This is typically transient as the gut adapts. Drinking plenty of water with the capsule may help.

Guarana contains natural caffeine. In people who are sensitive to caffeine, it may cause mild jitteriness or difficulty sleeping, particularly if the capsule is taken late in the day. Taking it with lunch or dinner, as directed, may reduce this. If any symptom is persistent or troublesome, stop use and seek advice from a healthcare professional.

When Not to Use This Product

Reta3 should not be used by anyone with a known allergy or hypersensitivity to any of its ingredients. It is not recommended for children or for pregnant or breastfeeding women.

People who are sensitive to caffeine, or who have an existing heart rhythm condition, should consult a doctor first because of the guarana content. People with diabetes, or who take medication that lowers blood sugar, should also seek medical advice and monitor their levels closely, since the formula may affect glucose metabolism.

The supplement should not be used as a substitute for a varied and balanced diet. Do not exceed the recommended daily dose. If you take any prescription medicine or have an ongoing medical condition, speak to your doctor or pharmacist before starting.

Who May Consider This Product

Reta3 is designed for healthy adults who are following, or planning to follow, a calorie-controlled diet and want additional support with appetite control. People who struggle with frequent snacking or strong cravings for sugar and carbohydrates may find the fibre, L-glutamine and chromium content relevant.

It may also suit adults who experience energy dips during calorie restriction. Guarana provides natural caffeine, and L-leucine is included to help preserve lean muscle mass while body weight is being managed. Those with busy routines may appreciate that the dose is one capsule per day.

It is not intended for children, pregnant or breastfeeding women, or people with diabetes, heart rhythm conditions or caffeine sensitivity unless a doctor has approved its use. The product does not replace a balanced diet or medical care.

Directions for Use

The recommended dose is one capsule per day. Swallow it whole, without chewing, with two large glasses of water. It should be taken approximately 15 to 30 minutes before a meal, or during a meal, either lunch or dinner.

For those who have difficulty swallowing capsules, the capsule may be opened and its contents mixed with water. Taking it at lunch or dinner rather than late in the evening may help avoid sleep disturbance from the natural caffeine in guarana.

Do not exceed the recommended daily dose. Use the supplement alongside a varied and balanced diet. If you are unsure whether it is suitable for you, or if you take regular medication, ask a doctor or pharmacist before starting.
