VERIFIED COMPANY i

Boosts Metabolism For Up To 24% Faster Fat Burn

Weight Loss Stack is shown to activate your body's natural thermogenesis within the first 30 minutes - targeting the metabolic pathways that govern fat oxidation, blood sugar and energy output. The specific blend helps your body turn food into clean energy instead of storing it as fat, so you burn more calories around the clock without the afternoon crash.

Cuts Cravings & Controls Appetite In 4 Weeks

Sugar cravings and constant snacking are two of the biggest reasons diets fail. Weight Loss Stack works to rebalance the hunger hormones - including ghrelin, leptin and insulin - so you feel fuller for longer on less food. Most users report noticeably fewer cravings within the first 4 weeks, making portion control effortless and weight loss far easier to sustain.

Supports Hormones & Energy For Women Of All Ages

Weight loss in women is closely tied to hormones, and Weight Loss Stack is formulated to work with a woman's body at every stage of life. The blend helps support healthy estrogen, cortisol and thyroid balance while reducing bloating and water retention, so your body can release stubborn weight more efficiently - for lighter, more confident days and results that actually last.

Proven Health Benefits Of The Weight Loss Formula

LeanBalance Complex lifestyle

What It Is

The Weight Loss Formula is a natural blend that supports your weight management journey from two angles at once: feeding your gut microbiome to help curb sugar cravings, and supplying a highly absorbable protein blend to keep you full and support your metabolism.

This natural formula helps you feel lighter, less bloated and more in control of your appetite - by supporting healthy digestion, keeping you satisfied for longer, and helping you snack less between meals without harsh stimulants or restrictive diets.

It lays the perfect foundation for sustainable weight management: a balanced gut that keeps cravings in check, a satisfied appetite, and steady energy that works with you, not against you.

The Weight Loss Formula is a done-for-you natural blend. Simply take it every day so it can gently curb cravings, support satiety and keep your energy steady - all without any disruptions to your daily routine.

  • Biotic — a pure GOS prebiotic fiber that feeds your beneficial gut bacteria, helping reduce sugar cravings and overeating, support smooth digestion and improve mineral absorption
  • OBVProt — a highly absorbable blend of milk protein concentrate and whey protein isolate, similar in composition to human mother's milk, that supports muscle maintenance, satiety and appetite control

Frequently Asked Questions

Find answers to common questions about our products

Preimmu Weight Loss Formula is made up of Preimmu® OBVProt and Preimmu® Biotic.

✔ Preimmu® OBVProt is a highly absorbable protein blend, similar in composition to human mother's milk, that supports muscle maintenance, satiety and appetite control

✔ Preimmu® Biotic feeds your good gut bacteria, helps reduce sugar cravings and supports a flatter, more comfortable tummy after meals

✔ Together, the two formulas provide targeted nutrients for daily well-being, supporting digestion, steady energy and stronger immunity

Start your morning by dissolving 1 sachet of Preimmu® OBVProt in warm water, milk, or a smoothie - a great way to replenish what the body has used overnight. You can add a spoonful of cinnamon, banana, avocado or berries to taste.

During the day, stir 1 sachet of Preimmu® Biotic into your coffee, tea, or any drink of your choice - it won't change the taste.

For heavy workloads, intensive physical activity, or for seniors, OBVProt can be taken 2–4 times a day. For best results, we recommend using both products consistently for at least 30 days.

OBVProt has a neutral taste that blends well with water, milk or smoothies -cinnamon, banana, avocado or berries can be added for extra flavor.

Biotic comes as a powder with a neutral, mildly sweet taste - it dissolves easily in any hot or cold drink without altering the flavour.

Our formulas are produced in the European Union in small batches to maintain ultra-high quality. They meet the most rigorous EU standards for safety and purity - some of the strictest standards in the world.
