RULE 1 CLEAN GAINER Clean Gainer sits in an interesting position within the Rule 1 range — it's the step between their protein powders and the R1 Mass Gainer, designed for people who want to add size and calories without the full 1,260-calorie sledgehammer of the Mass Gainer. At 560 calories per serve with a 3:1 carbohydrate-to-protein ratio, it delivers genuine mass-building support in a more measured, everyday-usable format that's also considerably easier to stomach and digest than the larger gainer. What separates Clean Gainer from most products in this category is the thoughtfulness of both the carbohydrate blend and the protein matrix. Where many mass gainers lean heavily on cheap maltodextrin and a single protein source, Rule 1 has built Clean Gainer around a six-ingredient carb blend that includes multiple organic whole-food sources, a four-protein matrix covering fast and slow digestion, and a genuine lipid blend using functional oils. No creamers, no gums, no amino spiking, no soy protein, and no banned substances — consistent with Rule 1's approach across everything they make. The carbohydrate blend Clean Gainer draws carbohydrates from six sources, each contributing something different to the overall energy and nutritional profile of the formula. Maltodextrin provides the fast-release glucose polymer base — the primary driver of caloric density and rapid glycogen replenishment post-training. Organic Quinoa is a complete grain source that contributes slow-releasing complex carbohydrates, dietary fibre, and a complete amino acid profile — making it a nutritionally meaningful addition rather than empty starch. Organic Blueberry Powder contributes natural fruit-sourced carbohydrates alongside antioxidant polyphenols, giving the carbohydrate blend a subtle whole-food nutrition dimension. Ginger Root Powder is included for its digestive support properties — ginger is well established for reducing gastric discomfort, bloating, and nausea, which makes it a practical and thoughtful inclusion in a high-carbohydrate formula where digestive tolerance can be a challenge. Organic Rice Bran adds slow-releasing complex carbohydrates with naturally occurring fibre, vitamins, and minerals, moderating the overall digestion rate of the carb blend. Oat Fibre contributes dietary fibre to support satiety, digestive health, and a gradual energy release curve. The 4g of dietary fibre per serve is a meaningful amount for a mass gainer. Together, these six sources deliver 99g of total carbohydrates per serve with just 9g of total sugars and only 4g of added sugars — a notably clean sugar profile for a product of this caloric density. The four-source protein matrix Where the R1 Mass Gainer uses three whey sources only, Clean Gainer uses a more comprehensive four-protein blend that covers fast, medium, and slow digestion rates in a single serve. Whey Protein Concentrate provides a rich amino acid profile and a naturally creamy texture — the fast-acting primary protein source. Whey Protein Isolate brings higher protein concentration with lower fat and lactose, improving the overall protein quality and digestibility of the blend. Milk Protein Isolate is a complete milk-sourced protein that contains both whey and casein fractions in their natural ratio, contributing a medium-pace digestion profile and a calcium-rich amino acid contribution. Micellar Casein is the slowest-digesting protein available, forming a gel in the stomach that releases amino acids steadily over a four-to-seven-hour window. Its inclusion in Clean Gainer makes this a genuinely multi-phase protein formula — fast-absorbing whey delivers aminos immediately post-training while the casein sustains protein availability for hours afterward, supporting muscle protein synthesis well into recovery. The 30g of protein per serve delivers over 14g of essential amino acids and more than 6g of BCAAs from the natural content of the protein blend. The lipid blend Most mass gainers carry whatever fat ends up in the formula incidentally — Clean Gainer takes a different approach with a deliberate four-oil lipid blend delivering 5g of fat per serve. Medium Chain Triglycerides (MCTs) are rapidly metabolised for energy — bypassing the usual fat digestion pathway and entering the bloodstream quickly, where they can be used as a direct fuel source rather than stored. Flaxseed Powder contributes plant-based omega-3 alpha-linolenic acid (ALA) alongside lignans and fibre. Avocado Powder provides monounsaturated fatty acids — the same healthy fat profile that makes whole avocados a staple in performance nutrition — alongside fat-soluble vitamins and phytosterols. Sunflower Oil Powder contributes polyunsaturated fatty acids including linoleic acid, rounding out a diverse fat profile that covers multiple fatty acid types rather than relying on a single oil source. Per serve (two scoops): 560 calories 99g total carbohydrates (4g dietary fibre, 9g total sugars, 4g added sugars) 30g protein (over 14g EAAs, over 6g BCAAs) 5g total fat (3.5g saturated) 280mg calcium 570mg potassium 310mg sodium 4.8mg iron Key features: 560 calories per serve — practical mid-range mass gainer 3:1 carbohydrate-to-protein ratio Six-source carbohydrate blend including Organic Quinoa, Blueberry, Rice Bran, Oat Fibre, and Ginger Four-source protein matrix: WPC, WPI, Milk Protein Isolate, and Micellar Casein Functional lipid blend: MCT, Avocado, Flaxseed, and Sunflower oils No creamers, no gums, no amino spiking, no soy protein, no banned substances 5.0 stars / 6 reviews / 100% recommend Available in 15-serve and 30-serve sizes Contains milk and soy Flavours available: Chocolate Fudge, Chocolate Peanut Butter, Cookies & Cream, Vanilla Creme Who is it for? Clean Gainer suits hard gainers who want a more nutritionally sophisticated mass support product than a basic maltodextrin-and-whey formula — people who care about the quality of what they're using to build size, not just the raw caloric number. The 560-calorie serve is practical for daily use between meals or post-workout without being overwhelming, and the organic whole-food carbohydrate sources and multi-phase protein matrix make it a noticeably better quality product than most of the mass gainer category. It's also the right choice for anyone who wants the mass-building benefits of a gainer but found the R1 Mass Gainer's 1,260-calorie serve too heavy on the stomach or too calorie-dense for their current phase. Directions: Mix two scoops with 420–480ml of water, milk, or your preferred beverage in a shaker cup or blender. Consume post-workout or between meals to support daily caloric intake. Can also be blended with fruit, nut butter, and ice for a protein-fortified smoothie, or blended with whole milk and ice cream for a higher-calorie shake option. Do not use as a sole source of nutrition. Warning: Not suitable for children under 15 years of age or pregnant women. Should only be used under medical or dietetic supervision. This product is not a sole source of nutrition and should be consumed in conjunction with a nutritious diet and an appropriate training or exercise programme. Contains milk and soy.
