Reta3

Clinic Overview of Reta3

Reta3 is a dietary supplement in capsule form. It brings together plant extracts, amino acids and essential minerals in a single daily capsule. The formulation is designed to support weight balance alongside a sensible eating pattern, rather than to replace one.

The product is made by Reta3. Its seven active ingredients are guarana extract, apple cider vinegar extract, Jerusalem artichoke inulin powder, L-glutamine, L-leucine, zinc citrate and chromium picolinate. Each one has a defined role, and the doses are listed in the table below.

Reta3 is aimed at adults who want help with appetite control, cravings and metabolism while they manage their calorie intake. It may also suit people who notice energy dips or a pull towards sugary food between meals. It is not intended for children, or for pregnant or breastfeeding women.

The way it works is straightforward. Inulin and apple cider vinegar act on fullness and the pace of digestion. Guarana provides natural caffeine to support energy and thermogenesis. Chromium and zinc contribute to normal macronutrient metabolism, while L-leucine and L-glutamine support muscle and gut health during a controlled diet.

Formulation Breakdown of 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 fiber 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 glycemic fluctuations

What Patients Hope to Gain

The main aim of Reta3 is to support natural weight balance and body composition management. It does this through several routes at once, which is why the formula combines fibre, minerals, amino acids and plant extracts rather than relying on one active.

Appetite and cravings are the first area. Jerusalem artichoke inulin is a soluble prebiotic fibre that swells in the stomach and increases the feeling of fullness. Apple cider vinegar contains acetic acid, which slows gastric emptying and promotes satiety. L-glutamine may also help reduce sugar and carbohydrate cravings.

Metabolism and energy are the second area. Guarana is rich in natural caffeine and is known to support thermogenesis, the body's heat production, and fat breakdown. It can lift physical energy and mental alertness, which many people find useful when they are eating less. The formula offers a natural energy boost without a heavy stimulant load.

Blood sugar is the third area. Apple cider vinegar helps blunt post-meal glucose spikes, and chromium picolinate contributes to the maintenance of normal blood glucose levels. Zinc and chromium together contribute to normal macronutrient metabolism, meaning how your body handles carbohydrates, fats and proteins.

Finally, Reta3 looks after muscle and gut health. L-leucine activates the mTOR pathway and helps preserve lean muscle mass during weight loss. L-glutamine supports the integrity of the gut barrier, and zinc supports normal immune function and cognitive performance.

Side Effects and Tolerability

Reta3 is generally well tolerated, but as with any supplement, some people notice effects. The most commonly reported is mild digestive discomfort, such as bloating or gas, during the first days of use. This is linked to the inulin fibre and is typically transient as your gut adjusts.

Because guarana contains natural caffeine, you may feel slightly jittery or find it harder to sleep if you take the capsule late in the day. Taking it with lunch or dinner, as directed, and avoiding other strong caffeine sources around the same time can help. Dry mouth has also been reported, but it is rare, affecting up to 1 in 1,000 users.

If any symptom is persistent or bothers you, stop taking the product and speak to a doctor or pharmacist.

Who Should Seek Advice First

Do not take Reta3 if you have a known allergy or hypersensitivity to any of its ingredients. Check the composition table carefully before you start. The product is not recommended for children, or for pregnant or breastfeeding women.

Because guarana is a source of caffeine, people with caffeine sensitivity or an existing heart rhythm condition should consult a doctor first. Likewise, if you have diabetes or take blood sugar-lowering medication, speak to your doctor before use. Apple cider vinegar and chromium act on glucose metabolism, so your levels should be monitored closely.

Reta3 is a food supplement and should not be used as a substitute for a varied and balanced diet. Do not exceed the recommended daily dose. If you are on any regular medication or have a long-term health condition, ask a healthcare professional for advice beforehand.

How It Is Made and Quality Standards

Reta3 is manufactured and marketed by Reta3, which is listed as the producer of the formulation. As with most food supplements, the product is made in capsule form with a defined list of active ingredients and stated doses, so you can see what each capsule contains.

In the supplement sector, good practice generally means using ingredients of consistent quality, controlling doses from batch to batch, and storing the finished product away from heat and moisture. We do not cite specific certifications for this product, because none are documented in the information available to us.
