Cognitive clarity
Reduced caloric intake affects concentration and mental sharpness, particularly as your body adapts to a new intake level.
Citicoline & Korean Ginseng
Six areas. One formula.
Effects of the modern weight loss journey
GLP-1 medications reduce appetite by 30 to 60%. That's the point. But eating less means absorbing less of the nutrients your body depends on. CHAPTER. was built around six specific gaps, each addressed with clinical grade ingredients at doses that matter.
Digestive discomfort
Slowed gastric emptying is among the most commonly reported side effects. Nausea, bloating, and constipation are frequent, particularly in the first weeks.
Ginger, Sunfiber & DigeZyme
Hydration
Up to 20% of daily fluid intake comes from food. Reduced appetite means reduced hydration, compounded by nausea that makes drinking harder.
Full Electrolyte Matrix
Recovery & sleep
Magnesium deficiency disrupts sleep quality and physical recovery. Tiredness can quietly undermine the consistency your journey depends on.
Magnesium Bisglycinate
Muscle preservation
Rapid weight loss does not distinguish between fat and muscle. Without support, lean mass goes with it, and lean mass drives metabolism.
Creatine Monohydrate
Nutritional gaps
Eating dramatically less means absorbing dramatically less. B vitamins, magnesium, zinc, chromium. The micronutrients energy and mood run on.

The formula
26 ingredients.
All chosen with purpose.
Five areas of support. Each ingredient at a clinically considered dose. Nothing included for label appeal. Nothing underdosed.
Performance & cognitive support
3 ingredients
+
Micronised Creatine Monohydrate3,000mg
Muscle maintenance · Energy production
GLP-1 medications cause significant appetite suppression. Fewer calories mean accelerated muscle loss during weight reduction. Creatine at 3,000mg daily is one of the most evidence-backed interventions for preserving lean muscle mass during a caloric deficit.
Citicoline (CDP-Choline Sodium)200mg
Focus · Cognitive function
Reduced caloric intake directly impacts cognitive clarity. Citicoline at 200mg supports acetylcholine synthesis, a neurotransmitter central to focus and memory, helping address the brain fog commonly reported in early GLP-1 use.
Korean Ginseng Extract5mg
Adaptogenic energy · Clarity
A low-dose adaptogen included to support sustained energy and mental clarity without stimulant effects. Particularly relevant during the adjustment period of GLP-1 use, when fatigue is common.
Digestive comfort & gut health
3 ingredients
+
Sunfiber® (PHGG)500mg
Gut motility · Digestive comfort
GLP-1 medications slow gastric emptying, which disrupts gut motility. Sunfiber® is a clinically studied partially hydrolysed guar gum that supports regularity and digestive comfort without the bloating associated with many fibres.
DigeZyme® Digestive Enzymes50mg
Nutrient absorption · Digestive efficiency
When eating significantly less, getting maximum nutrition from every meal matters. DigeZyme® is a multi-enzyme complex that supports the breakdown of proteins, fats, and carbohydrates, improving nutrient absorption efficiency.
Ginger Root Extract8.75mg
Nausea relief · Digestive comfort
Nausea is among the most commonly reported side effects of GLP-1 medications, particularly in the first weeks of use. Ginger root extract is one of the most studied natural interventions for nausea and digestive comfort.
Electrolyte & mineral matrix
6 ingredients
+
Magnesium Bisglycinate & Malate100mg
Muscle function · Recovery · Rest
Magnesium deficiency deepens with reduced food intake. The bisglycinate and malate forms are chosen for superior bioavailability and a gentle digestive profile, critical given the GI sensitivity common in GLP-1 users.
Potassium Chloride & Citrate400mg
Hydration · Nerve function
Reduced food intake reduces potassium from dietary sources. Combined with lower hydration from eating less water-dense food, electrolyte balance becomes harder to maintain. 400mg supports fluid regulation and nerve signalling.
Sodium Chloride300mg
Fluid balance · Electrolyte replenishment
The primary extracellular electrolyte, included to complete the matrix alongside potassium and magnesium. Supports proper fluid balance when dietary sodium intake drops with reduced eating.
Zinc Bisglycinate5mg
Immune function · Metabolism
Zinc is frequently depleted with caloric restriction. The bisglycinate chelate form offers significantly better absorption than cheaper zinc oxide forms, meaningfully addressing what reduced food intake cannot supply.
L-Selenomethionine30µg
Antioxidant protection · Thyroid health
The organic selenomethionine form provides the best bioavailability of any selenium compound. Critical for thyroid hormone synthesis and antioxidant defence, both areas of relevance during significant metabolic change.
Chromium Picolinate20µg
Blood glucose · Macronutrient metabolism
Chromium supports insulin sensitivity and macronutrient metabolism. Particularly relevant for GLP-1 users, whose relationship with blood glucose is already the central focus of their medication. Picolinate is the most bioavailable form.
Vitamin B complex
8 ingredients
+
Vitamin B1 (Thiamine Hydrochloride)1.1mg
Energy metabolism · Nerve function
Essential for converting carbohydrates into usable energy and supporting nerve function. B vitamins are among the first micronutrients to fall with reduced food intake, and all eight are included at 100% reference intake.
Vitamin B2 (Riboflavin)1.4mg
Energy metabolism · Reduces fatigue
Plays a central role in energy production and the metabolism of fats, carbohydrates, and proteins. Particularly relevant during the dietary changes that accompany GLP-1 use.
Vitamin B3 (Nicotinamide)16mg
Energy metabolism · Nervous system
Supports energy metabolism and nervous system function. Also contributes to normal psychological function, relevant during the adjustment period of GLP-1 use.
Vitamin B5 (Calcium D-Pantothenate)6mg
Energy metabolism · Mental performance
Supports the synthesis of coenzyme A, involved in the metabolism of carbohydrates, proteins, and fats. Also contributes to normal mental performance.
Vitamin B6 (Pyridoxine Hydrochloride)1.4mg
Protein metabolism · Immune function
Critical for protein metabolism, important when dietary protein intake falls with reduced appetite. Also supports immune function and the regulation of hormonal activity.
Vitamin B7 (Biotin)50µg
Macronutrient metabolism · Hair & skin
Supports macronutrient metabolism and contributes to normal maintenance of hair, skin, and mucous membranes, areas that can be affected during significant weight change.
Vitamin B9 (Folic Acid)200µg
Cell division · Immune function
Supports cell division and immune function. Also contributes to normal amino acid synthesis, relevant when protein intake is reduced due to appetite suppression.
Vitamin B12 (Methylcobalamin)2.5µg
Energy metabolism · Reduces fatigue
Provided as methylcobalamin, the most bioavailable and metabolically active form of B12. Supports energy metabolism, red blood cell formation, and the reduction of fatigue.
All eight B vitamins at 100% reference intake.
Antioxidant & immune support
4 ingredients
+
Vitamin C (Calcium Ascorbate)80mg
Immune function · Collagen synthesis
Calcium Ascorbate is a buffered, gentle form of Vitamin C, well-suited to GI-sensitive users. Supports immune function and collagen synthesis, the latter particularly relevant when skin elasticity is affected by weight change.
Vitamin D3 (Vegan Cholecalciferol)5µg
Immune function · Bone health
Vegan D3 derived from lichen, the same bioactive form as animal-derived D3. Critical for immune modulation and calcium absorption. Deficiency is extremely common before dietary changes reduce intake further.
Vitamin E (D-Alpha Tocopherol)12mg
Antioxidant protection · Cell health
The natural D-alpha form offers superior bioavailability over synthetic DL-alpha. A key fat-soluble antioxidant protecting cell membranes from oxidative damage, important during periods of metabolic transition.
Vitamin A (Beta-Carotene)800µg
Immune function · Skin health
Provided as beta-carotene, the precursor form that converts to active Vitamin A as needed, eliminating any risk of toxicity from over-supplementation. Supports immune defence and skin integrity.
