The Best Weight Loss Muscle Gain Supplements, Reviewed

#1Best Overall

MuscleTech Nitro-Tech Ripped Whey Protein

MuscleTech Nitro-Tech Ripped Whey Protein
Protein per scoop30g
Servings per tub40 scoops
Key ingredientswhey peptides, isolate
Added compoundsC. canephora robusta, L-carnitine
Tub weight4.0 pounds
Check Latest Price →

What We Like

  • High 30g protein per serving
  • Includes studied metabolism-boosters
  • Large 40-serving container size
  • Designed for lean muscle and weight management

Trade-offs

  • Requires twice-daily mixing and meal timing
  • Full 60-day use recommended for cited results

A 30-gram protein serving combined with clinically referenced metabolism-supporting ingredients creates a formula specifically engineered for simultaneous muscle support and weight management. This makes it a logical central choice for disciplined individuals following a structured diet and exercise plan who want a single supplement to address both goals. The large four-pound tub supplies a two-month supply at the directed twice-daily use, aligning with the 60-day study timeframe mentioned.

The trade-off is a protocol. You must mix it twice a day, 30 to 60 minutes before your two largest meals. It’s not a simple post-workout shake. For someone seeking a simpler, single-ingredient protein hit without the added compounds or specific schedule, the Pro Nutrition Labs Her Natural Whey Protein offers a more straightforward, compact option at one pound.

Best for: Disciplined athletes on a timed meal plan seeking a combined muscle-building and weight-management powder. Not ideal for those wanting a simple, occasional-use protein or a highly portable supplement.

#2Best For Women

Pro Nutrition Labs Her Natural Whey Protein

Pro Nutrition Labs Her Natural Whey Protein
Protein per serving20g
Calories per serving110
Carbohydrates per serving3g
SweetenerStevia
SourceGrass-fed whey isolate
Check Latest Price →

What We Like

  • Low-calorie, high-protein formula for weight management
  • Sugar-free and free from artificial fillers
  • Naturally sweetened for a clean taste profile
  • Compact 1-pound container is easily portable

Trade-offs

  • Single-pound size is small for high-frequency users

With 20 grams of protein packed into just 110 calories, this formula is engineered for a specific calorie-conscious math. It’s built for someone whose primary goal is leaning out while preserving muscle, not necessarily for someone aiming to pack on mass with a huge calorie surplus. The grass-fed whey isolate and stevia-only sweetening align with a clean-ingredient philosophy, which matters if you’re skeptical of proprietary blends and artificial additives.

Pro Nutrition Labs Her Natural Whey Protein delivers a focused 20 grams of protein in a 110-calorie serving, which provides a clean nutritional profile for post-workout recovery or a diet-friendly shake. Unlike blends such as Ancient Nutrition’s Grass Fed Whey + Fat Loss, it omits added metabolism boosters, positioning it as a straightforward protein supplement. The one-pound container size suits individual use rather than high-volume household supply.

Best for: Women seeking a clean, low-calorie protein powder to support a weight loss and muscle maintenance diet. Not ideal for those seeking maximum muscle growth with high protein per serving or additional fat-burning compounds.

#3Best 2-in-1 Builder & Shredder

Nutrex Research Anabol Ripped

Nutrex Research Anabol Ripped
Product TypeCapsules
Count60 capsules
Key Function2-in-1 muscle builder & thermogenic
Target SupportMuscle protein synthesis & recovery
Packaging Weight0.1 pounds
Check Latest Price →

What We Like

  • Combines anabolic and thermogenic support in one formula.
  • Aims to support post-workout recovery and training consistency.
  • Compact, lightweight bottle for easy transport.

Trade-offs

  • Only 60 capsules, requiring frequent repurchase for ongoing use.
  • Formula complexity may not suit those seeking single-ingredient supplements.

Nutrex Research Anabol Ripped combines anabolic support with thermogenic ingredients in a single formula, which simplifies a supplement stack for lifters focused on both muscle growth and metabolic activity. This 2-in-1 design aims to aid muscle protein synthesis and post-workout recovery while supporting calorie utilization, fitting into a structured training and nutrition plan. The advanced formula is intended for those who want to address muscle development and body composition goals without managing multiple separate products.

A single 60-count bottle weighs just 0.1 pounds, making it exceptionally portable for a gym bag. With daily use, the supply lasts for a standard two-month cycle, offering a compact, pill-based alternative to powdered supplements like the larger MuscleTech Nitro-Tech Ripped Whey Protein. This product delivers its combined muscle-building and thermogenic support in capsule form, eliminating any need for mixing or preparation.

Best for: Men following a structured fitness program who want a combined muscle growth and thermogenic support supplement in a single capsule.

#4Best With Clinically Studied Blend

Ancient Nutrition Grass Fed Whey + Fat Loss Blend

Ancient Nutrition Grass Fed Whey + Fat Loss Blend
Protein per serving23 grams
Key functional blendClinically studied fat loss blend
SourceGrass-fed whey & organic A2/A2 milk
Servings per container18
FlavorVanilla Cinnamon
Check Latest Price →

What We Like

  • Includes a clinically studied ashwagandha and cinnamon blend.
  • Uses organic, grass-fed, and gut-friendly A2/A2 milk protein.
  • Formulated to support metabolism and lean body composition.
  • Convenient powder form mixes easily into water or smoothies.

Trade-offs

  • Only 18 servings per container requires frequent repurchase.
  • Combines two goals, which may not suit those seeking pure muscle gain.

The inclusion of a clinically studied fat loss blend with organic cinnamon and ashwagandha is the defining feature. This positions the product for the buyer who wants a single powder to address both sides of the body recomposition equation, supporting metabolism and calorie burning while delivering 23 grams of protein for muscle support. Its use of grass-fed, organic A2/A2 milk protein is a thoughtful touch for those prioritizing digestibility and sourcing.

With 18 servings per container, this protein blend will require more frequent reorders compared to bulk options like the 4-pound MuscleTech Nitro-Tech Ripped. Its formulation includes a clinically studied fat loss blend, which some buyers may find adds a layer of substantiation for its intended metabolic and weight management support.

Best for: The buyer seeking a protein powder combined with a clinically studied blend for weight management and metabolic support. Not ideal for someone needing a high-volume, cost-per-serving bulk protein for muscle building alone.

#5Best Beef Protein Isolate

MuscleMeds Carnivor Shred Beef Protein

MuscleMeds Carnivor Shred Beef Protein
Protein per serving23g
Dietary profile0 lactose, 0 sugar, 0 fat
CertificationsHalal Certified
Servings per container28
Check Latest Price →

What We Like

  • Includes metabolism-boosting compounds like green coffee bean
  • Beef protein isolate avoids dairy and lactose entirely
  • Halal certification meets specific dietary requirements
  • Formulation aims to reduce hunger and curb cravings

Trade-offs

  • The 175mg caffeine per serving is a substantial stimulant dose
  • At 2.3 pounds, it offers fewer servings than larger whey options
  • Beef protein is a niche alternative to more common dairy or plant proteins

A 23-gram hit of hydrolyzed beef protein isolate makes this a definitive pick for anyone who needs to build muscle but can’t tolerate dairy. The inclusion of 175 milligrams of caffeine alongside green tea and yerba mate creates a legitimate thermogenic stack, so this powder is doing double duty as a pre-workout and a protein source. It suits the skeptical tinkerer who wants a single, consolidated product and doesn’t mind the stimulant kick. The Halal certification and complete absence of lactose or sugar are clear, practical wins for specific dietary protocols.

The trade-off is that you’re committing to a beef-based protein, which is less common and might not blend or taste like the whey you’re used to. Compared to something like the MuscleTech Nitro-Tech Ripped, which is a whey isolate, you’re getting a different amino profile and a much more aggressive stimulant blend. This isn’t a gentle, before-bed shake. It’s a metabolic tool for a specific window, and the container size is modest, so you’ll be reordering it more frequently than a four-pound tub.

Best for: Dairy-free lifters seeking a combined protein and thermogenic stimulant boost. Not ideal for anyone sensitive to caffeine or preferring a simple, unflavored protein powder.
#6Best For Carb Utilization

Alpha Lion Gains Candy DHB Berberine

Alpha Lion Gains Candy DHB Berberine
Key IngredientDihydroberberine (DHB)
Form60 capsules
Primary FunctionCarbohydrate utilization support
Dosing FrequencyUp to 3 times daily
Target UseBefore carb-dense meals
Check Latest Price →

What We Like

  • Features the GlucoVantage form of DHB.
  • Designed to direct carbs to muscle, not fat storage.
  • Versatile for fat loss, muscle support, and pumps.

Trade-offs

  • Requires precise timing relative to meals for effect.
  • Mechanism hinges heavily on dietary carbohydrate intake.

Alpha Lion Gains Candy uses GlucoVantage, an implementation of dihydroberberine known for inhibiting fat cell growth, which targets the body’s response to carbohydrates. The formula is intended to help store carbs as muscle glycogen and use them for energy instead of storing them as fat. This mechanism makes it a consideration for those seeking to manage fat storage while continuing to eat carbohydrate-dense meals.

Its utility is intrinsically linked to your carbohydrate intake. This is not a magic pill for a poor diet but a potential tool for managing a moderate one. A straightforward protein powder like MuscleTech Nitro-Tech Ripped builds muscle through direct amino acid delivery. In contrast, Gains Candy operates on a more metabolic level by attempting to influence where your existing calories are stored. It functions as a supplementary strategy, not a foundational one.

Best for: Disciplined individuals with a moderate-to-high carbohydrate intake seeking to improve nutrient partitioning for body composition. Not ideal for those on a strict ketogenic or very low-carb diet.

#7Best Stimulant-Free Fat Burner

Unaltered CLA Weight Loss Pills

Unaltered CLA Weight Loss Pills
Key IngredientConjugated Linoleic Acid (CLA)
Serving Size3 softgels
CLA per Serving3,000 milligrams
SourceSafflower oil standardized to 80% CLA
Servings per Bottle30
Check Latest Price →

What We Like

  • Stimulant-free formula with no caffeine or jitters
  • 3,000 mg clinically studied CLA per serving
  • Designed to support lean muscle mass during weight loss
  • Simple one-ingredient, no-proprietary-blend formulation

Trade-offs

  • No metabolic stimulants for immediate energy boost
  • Targeted primarily at men in their 30s and 40s

A 3,000-milligram dose of conjugated linoleic acid per serving provides a stimulant-free mechanism studied for supporting body fat reduction and lean mass preservation. This makes the Unaltered CLA pills a logical choice for the active man who wants to run a caloric deficit without the wired feeling or crash of caffeine-based burners. It works quietly in the background, which suits anyone stacking it with a pre-workout or coffee, or who simply prefers their supplements not to interfere with sleep.

Its stimulant-free, caffeine-free formula means there is no metabolic kickstart or surge of energy, so the pills work biochemically in the background. This requires pairing them consistently with training and diet, contrasting with stimulant-based fat burners like Old School Labs Vintage Burn. The product uses a single, studied ingredient with no proprietary blend, and the full 3,000 mg CLA dose is printed on the label.

Best for: Active men seeking a non-stimulant, single-ingredient fat loss aid to pair with their existing training and nutrition, particularly during a cutting phase. Not ideal for those seeking an immediate energy boost or appetite suppression from their supplement.
#8Best Non-Stimulant Drink Mix

BPI Sports CLA + Carnitine Shredded

BPI Sports CLA + Carnitine Shredded
Key IngredientsCLA plus L-Carnitine
Caffeine ContentZero caffeine
Servings per Container50 servings
FlavorTropical Mango
FormDrink mix powder
Check Latest Price →

What We Like

  • Stimulant-free formula avoids jitters
  • Supports fat conversion to energy
  • Mixes easily into cold water
  • Stacks with any pre-workout

Trade-offs

  • Requires consistent diet and exercise for results
  • No protein content for muscle synthesis

A caffeine-free drink mix combining CLA and L-Carnitine means you can support your metabolism and energy levels without the crash or sleep disruption common in stimulant-based fat burners. This suits someone who wants a daytime or nighttime metabolic aid that plays well with their existing pre-workout or cardio routine. The tropical mango flavor and easy mixing make it a practical addition to a hydration habit, which is useful for long-term adherence. It’s from a brand with a decade-plus track record in sports nutrition, which offers some peace of mind in a crowded market.

This is a stimulant-free drink mix designed to support weight management, not a protein supplement. For those aiming to build muscle, a dedicated protein powder like MuscleTech Nitro-Tech Ripped would be necessary alongside it. The formula combines conjugated linoleic acid and l-carnitine to aid the body’s conversion of stored fat into energy, making it a focused metabolic support tool when used with diet and exercise.

Best for: Athletes and gym-goers seeking a non-stimulant metabolic boost to pair with cardio and a disciplined diet. Not ideal for those looking for an all-in-one muscle-building protein or a pill-form convenience.

#9Best Premium Thermogenic

Old School Labs Vintage Burn

Old School Labs Vintage Burn
Product TypeThermogenic Fat Burner
Form120 Capsules
Key ClaimPreserves lean muscle
Key ClaimAppetite suppressant
OriginMade in the USA
Check Latest Price →

What We Like

  • Formulated to support fat-focused metabolic activity
  • Helps manage hunger and reduce cravings
  • Provides clean, steady energy without jitters
  • Made in the USA with high-quality ingredients

Trade-offs

  • Only 120 capsules per container
  • Weighs 0.3 pounds; lighter than protein powders

A premium thermogenic’s job is to support a defined, toned look without sacrificing muscle, and Vintage Burn is formulated specifically for that fat-focused metabolic activity. It suits someone who wants a clean, steady energy boost to power through their day and workouts, backed by a formula that also aims to curb appetite. This is for the disciplined user who prioritizes a comprehensive, made-in-the-USA approach to their supplement stack over a simple stimulant kick.

Old School Labs Vintage Burn is formulated to support fat-focused metabolic activity while helping preserve lean muscle, which targets a more defined physique. The bottle is 5.0 inches tall and weighs 0.3 pounds, making it a compact supplement that stores easily in a gym bag or cabinet. Unlike stimulant-free options such as Unaltered CLA pills, this formula includes a component for clean, steady energy without jitters, a feature for users whose daily routine can utilize that support.

Best for: Disciplined individuals seeking a comprehensive, multi-benefit thermogenic to support energy, appetite control, and muscle preservation during a cut. Not ideal for those seeking a high-volume, meal-replacement powder or a strictly stimulant-free fat burner.

#10Best With Ashwagandha

Unaltered Muscle & Fat Burner Bundle

Unaltered Muscle & Fat Burner Bundle
Key ingredient600 mg Ashwagandha Extract
CLA dosePotent dose of CLA
Additional ingredientsKorean Red Ginseng, Tribulus Terrestris, Vitamin D3
Stack compatibilityPairs with protein, creatine, pre-workout
Check Latest Price →

What We Like

  • Ashwagandha shown to enhance muscle strength and size
  • CLA scientifically shown to reduce body fat mass
  • Red Ginseng aids in reducing muscle soreness
  • Supports hormone balance with Tribulus and Vitamin D3

Trade-offs

  • No serving size or capsule count provided in the feature bullets
  • Requires consistent use for CLA fat mass reduction effect

This bundle’s 600 mg of Ashwagandha extract is a key dose shown to enhance muscle strength and size, offering a foundation for those aiming to improve body composition. It pairs this with CLA, which is scientifically shown to reduce body fat mass in overweight individuals with consistent use, targeting both muscle and fat. The formula includes Vitamin D3 and Tribulus Terrestris to help maintain hormone balance for sustained vitality, making it a candidate for men looking to stay active as they age.

This product is highly specific. It is not a protein powder or a standalone thermogenic but a hormonal and metabolic support bundle. For the primary goal of adding lean mass through protein synthesis, the MuscleTech Nitro-Tech Ripped Whey Protein provides a more direct route. However, if you are fine-tuning a full supplement stack and want targeted support for recovery, hormone vitality, and fat loss, this bundle’s combination of herbs and fatty acids fills that particular niche.

Best for: Men looking for a hormone-supporting supplement to pair with an existing workout stack for muscle preservation and fat reduction. Not ideal for those seeking a high-protein meal replacement or a fast-acting thermogenic fat burner.

How We Evaluated Weight Loss Muscle Gain Supplements

Our research focused on manufacturer specifications, documented ingredient profiles, and patterns in expert round-ups from fitness and nutrition sources. We prioritized formulas that combined a substantial protein source with clinically studied metabolism-supporting compounds, as these directly address the dual goals of fat loss and muscle growth. Key criteria included protein type and dose per serving, the presence and dosage of supporting ingredients like thermogenics or nutrient partitioners, and practical factors like container size and mixability.

Since this is a research-based evaluation, we cannot verify individual results or account for personal biochemical variability. Our aim is to provide a clear comparison of what each product is designed to do, based on its labeled formulation and intended use case.

What To Look For In Weight Loss Muscle Gain Supplements

The right supplement aligns with your primary goal, dietary restrictions, and tolerance for stimulants. Look for a formula that supports your protein intake and provides targeted metabolic or hormonal support without unnecessary fillers.

Prioritize a high-quality protein source (20-40g per serving) and check for clinically studied supporting ingredients. Consider your caffeine sensitivity and whether you prefer a powder for meal replacement or convenient pills.

Protein Source and Dose

Protein is foundational for muscle repair and growth, and it can enhance satiety during a calorie deficit. Whey protein isolate is a fast-absorbing, complete protein, while options like beef isolate cater to dairy-free needs. Research suggests consuming 20-40 grams of protein, particularly around workouts, effectively supports muscle building. The serving size and total servings per container determine both value and convenience for daily use.

Supporting Active Ingredients

Beyond protein, look for ingredients with evidence for supporting metabolism or nutrient partitioning. These include compounds like conjugated linoleic acid (CLA), green tea extract, ashwagandha, or berberine. For a thermogenic effect, check caffeine content, which can vary from zero to a significant amount per serving. A product combining these with protein creates a true supplement stack approach in a single formula.

Form and Practicality

Your daily routine dictates whether a powder, capsule, or drink mix works best. Powders offer meal-replacement versatility but require mixing. Capsules provide convenience but no protein. Also, assess the container size; a small tub may be portable but requires frequent repurchase, impacting long-term cost. For those focused purely on losing fat and gaining muscle, a stimulant-free pill or a non-stimulant drink mix might be the ideal stackable component.

  • Check the label for a “proprietary blend” which hides individual ingredient doses.
  • Note if the product requires specific timing, like with meals or pre-workout, for claimed effects.
  • Verify certifications if you need dairy-free, gluten-free, or halal options.

The most effective supplement is the one you will use consistently alongside a disciplined diet and training plan.

Frequently Asked Questions

Which supplement is best for weight loss and muscle gain?

The best single supplement combines adequate protein with metabolism-supporting ingredients. Our top overall pick, MuscleTech Nitro-Tech Ripped, exemplifies this with 30g of protein per serving and studied metabolism-boosters. For a different approach, the Ancient Nutrition Grass Fed Whey + Fat Loss Blend pairs protein with a clinically studied herbal blend for simultaneous fat loss and muscle gain.

Which diet is best for fat loss and muscle gain?

A diet with sufficient protein, a moderate calorie deficit, and strength training is essential. Supplements are tools within this framework, not replacements. Protein powders can help you hit daily targets, while specific supplements for recomposition like berberine or CLA may offer additional support when diet and training are already dialed in.

What should I take for weight loss and muscle gain?

Start with a high-quality protein supplement to ensure adequate intake for muscle preservation. Then, based on your needs, consider adding a separate thermogenic or nutrient-partitioning aid. Many find a combined product like the Nutrex Research Anabol Ripped simplifies this, offering a combination for fat loss and muscle in one capsule.

What are the best supplements for weight loss and muscle building?

The most evidence-backed categories are protein powders (whey, casein), creatine, and certain thermogenics like caffeine and green tea extract. Our list includes specialized options within these categories, such as the Alpha Lion Gains Candy DHB Berberine for improving carb utilization and the Unaltered CLA Weight Loss Pills as a stimulant-free choice.

Are there different supplements for men and women?

While fundamental physiology is similar, some formulas are marketed with gendered nutrient focuses. For example, they may include added iron for women or testosterone-supporting herbs for men. Our picks include the Pro Nutrition Labs Her Natural Whey Protein, a clean protein for women, and the Unaltered Muscle & Fat Burner Bundle, which includes ingredients for hormone balance often targeted in men’s supplements.

The Bottom Line

For disciplined athletes following a timed meal plan, the MuscleTech Nitro-Tech Ripped Whey Protein is the best overall choice, delivering high protein with metabolic support. Budget-conscious buyers or those with specific needs should look to our award winners, like the stimulant-free Unaltered CLA pills or the dairy-free MuscleMeds Carnivor Shred.

Ultimately, the most important factor is choosing a supplement that aligns with your diet, training consistency, and personal tolerance for ingredients like caffeine. No pill or powder replaces the fundamentals of nutrition and resistance training for body recomposition.
