Whether you are focused on building muscle, losing fat, or simply supporting your overall health, the right supplements can make a meaningful difference when paired with proper nutrition and training. If you have already used our Protein Calculator or Macro Calculator, you know exactly how much protein, carbs, and fat your body needs each day. Supplements help you fill the gaps when whole foods alone fall short.
Use these calculators to determine your nutritional needs before choosing supplements.
In this guide, we review six supplements that cover the most common fitness needs: protein for muscle recovery, creatine for strength, a multivitamin for micronutrient gaps, omega-3s for joint and heart health, and a pre-workout for training performance. Every product below was selected based on third-party testing, ingredient transparency, value for money, and thousands of verified user reviews.
★★★★★ 4.7 out of 5 stars
Optimum Nutrition Gold Standard Whey has been the best-selling protein powder in the world for over two decades, and for good reason. Each scoop delivers 24 grams of protein from a blend of whey protein isolate, whey protein concentrate, and whey peptides. The mixability is outstanding, and the flavor range (with over 20 options) is unmatched in the industry.
Anyone looking for a reliable daily protein supplement. Particularly great for people who have used our Protein Calculator and discovered they need 120-180g of protein daily but struggle to hit that target through food alone. One or two scoops per day bridges the gap efficiently.
Pair with our Protein Calculator to determine your exact daily protein needs, then use our Macro Calculator to see how a protein shake fits into your overall macros.
Pros: Industry-leading taste and mixability, trusted brand with decades of testing, excellent amino acid profile, widely available
Cons: Contains artificial sweeteners (sucralose), not the cheapest per serving, contains soy lecithin
★★★★☆ 4.5 out of 5 stars
Myprotein Impact Whey consistently delivers solid nutrition at one of the lowest prices per gram of protein on the market. With 21 grams of protein per serving and a massive range of flavors (over 40), it proves you do not need to overspend to hit your protein targets. The brand is one of the largest sports nutrition companies in Europe and has built a loyal following for quality on a budget.
Students, beginners, and anyone who needs a high volume of protein powder without breaking the bank. If your calorie deficit plan requires high protein intake to preserve muscle while cutting, this is the most cost-effective way to get there.
Use our Calorie Deficit Calculator to set your target, then lean on Impact Whey to hit high-protein targets without excessive calories (only 103 calories per scoop).
Pros: Unbeatable price per serving, solid amino acid profile, huge flavor selection, frequent sales and discounts
Cons: Some flavors are inconsistent, mixability not quite as smooth as ON Gold Standard, bag packaging can be messy
★★★★★ 4.6 out of 5 stars
Creatine monohydrate is the most researched and effective sports supplement in existence. Thorne's version stands out because it is NSF Certified for Sport, meaning it has been independently tested to verify that it contains exactly what the label claims and nothing else. This matters if you compete in any tested sport or simply want the highest purity available.
Anyone engaged in resistance training or high-intensity exercise. Creatine increases phosphocreatine stores in your muscles, allowing you to produce more ATP during heavy lifts. Research consistently shows 5-10% improvements in strength and power output. It also supports muscle hydration and may benefit cognitive function.
As you build strength and lean mass with creatine, track your progress using our Body Fat Calculator. Note that creatine may cause 2-4 lbs of water weight gain initially, so use our TDEE Calculator to ensure your calorie intake supports your training goals.
Pros: NSF Certified for Sport, ultra-pure single ingredient, no taste or texture when mixed, excellent value at 90 servings
Cons: Premium price compared to generic creatine, unflavored only, initial water retention can mask fat loss on the scale
★★★★☆ 4.5 out of 5 stars
When you are in a calorie deficit or following a restricted diet, micronutrient gaps become more likely. Garden of Life Vitamin Code is made from raw, whole-food sourced nutrients rather than synthetic vitamins, which may improve bioavailability and absorption. It includes a blend of 23 fruits and vegetables along with live probiotics and enzymes.
Active individuals who are dieting or eating in a calorie deficit. When you reduce food intake, you also reduce micronutrient intake. A quality multivitamin acts as nutritional insurance, supporting immune function, energy metabolism, and recovery. Also excellent for anyone who does not eat a highly varied diet.
If your Calorie Deficit Calculator results show a significant deficit (500+ calories below maintenance), a multivitamin helps ensure you are not sacrificing essential micronutrients while losing weight.
Pros: Whole food sourced for better absorption, includes probiotics and enzymes, comprehensive nutrient profile, no synthetic fillers
Cons: Requires 4 capsules per day, higher price than synthetic multivitamins, large capsule size
★★★★★ 4.6 out of 5 stars
Omega-3 fatty acids are essential for recovery, joint health, and reducing inflammation from intense training. Nordic Naturals is the number one selling omega-3 brand in the United States, and their Ultimate Omega delivers a concentrated 1280mg of omega-3s per serving in the highly bioavailable triglyceride form. Every batch is third-party tested for purity and freshness.
Anyone who trains regularly and wants to support joint health, reduce exercise-induced inflammation, and maintain cardiovascular health. Omega-3s are especially important if you do not eat fatty fish at least twice per week. Research also suggests omega-3s may improve muscle protein synthesis when combined with resistance training.
Use alongside our Macro Calculator to ensure your fat intake includes adequate omega-3s. If your TDEE plan has you eating less dietary fat, supplementation becomes even more important.
Pros: High potency in triglyceride form, no fishy burps with lemon coating, award-winning purity testing, sustainable sourcing
Cons: Two soft gels per serving, higher cost than bulk fish oil, must be refrigerated after opening for freshness
★★★★☆ 4.5 out of 5 stars
Transparent Labs BULK stands out in a crowded pre-workout market by doing exactly what its brand name implies: being completely transparent about every ingredient and dose. There are no proprietary blends hiding underdosed ingredients. Every component is included at clinically studied dosages, making this one of the most effective pre-workouts available.
Lifters and athletes who want maximum performance from their workouts without mystery ingredients. Particularly valuable during a cutting phase when energy is lower due to reduced calorie intake. The moderate caffeine dose (200mg, roughly two cups of coffee) provides energy without the jitters or crash that higher-stimulant products cause.
When you are in a calorie deficit, training intensity often drops. A quality pre-workout helps maintain performance so you preserve muscle mass. Track your body fat percentage to confirm you are losing fat, not muscle.
Pros: Fully transparent label, clinically effective doses, clean ingredients with no artificial junk, great flavors
Cons: Premium price per serving, beta-alanine tingles can be uncomfortable for some, limited availability in retail stores
