The Complete Guide to Supplements: How to Build a Stack That Actually Works

You can see supplements for almost everything. From supplements that help sharpen your training to those that speed up recovery and fill the nutritional gaps your diet might leave behind. 

However, supplements are exactly what the word describes; they should only support an already solid foundation. They don’t replace the nutritional and health basics. No pill, powder, or pre-workout can make up for inconsistent training, poor sleep, or a diet that’s missing the basics. 

This guide is for anyone who has asked: What supplement should I take? 

If you are still wondering which supplements are best for your goals and needs, we’ll provide some guidance. Instead of chasing trends or loading up on 20 different products with loads of different ingredients, you’ll learn how to evaluate supplements based on evidence, your specific goals, and what your body actually needs. 

TL;DR: Complete Guide To Supplements

• Build the foundation first: protein, creatine, and key micronutrients where needed.
• Add supplements based on your specific goal instead of random products..
• Effective ingredients and proper doses are much more than the number of ingredients.
• Look for reputable third-party testing and transparent labels.
• Consistency matters more than constantly changing your supplement stack.

How to Think About Supplements: Evidence Tiers

Not all the supplements are the same, and the research to back them up is going to vary a lot. Some ingredients have decades of clinical trials behind them. Others, while they are promising, are still in the early stages of research. 

Understanding the different tiers behind supplements makes it easier to decide where to spend your money and where to be more cautious. Supplements fall into 3 main tiers based on well research supports their use.

Evidence Tier	What It Means	Common Ingredients
Tier 1: Strong Evidence	Backed by consistent, well-established research demonstrating benefits for specific health or performance outcomes.	Protein, Creatine, Caffeine, Beta-Alanine, Electrolytes
Tier 2: Moderate or Situational Evidence	Research supports potential benefits, but effectiveness may depend on the individual, intended use, or specific conditions.	L-Citrulline, Nitrates, Collagen, Greens, Adaptogens
Tier 3: Emerging or Limited Evidence	Early research suggests possible benefits, but more high-quality human studies are needed to confirm effectiveness.	Nootropics, NMN, Resveratrol, Many Proprietary Blends

Tier 1 — Strong Evidence

These are ingredients that have consistent, well-documented research supporting their benefits:

• Protein: Supports muscle growth and repair by providing the amino acids your body needs to build and maintain muscle [1].
• Creatine: Helps improve strength, power, and high-intensity exercise performance by increasing your muscles’ rapid energy supply [2].
• Caffeine: Increases alertness and energy while helping improve focus and exercise performance [3].  
• Beta-alanine: Helps delay muscular fatigue during hard, high-intensity exercise by increasing muscle carnosine levels [4].
• Electrolytes: Help maintain hydration, fluid balance, and normal muscle and nerve function, especially when you’re losing fluids through sweat [5].

Even with strong evidence, how useful they are still depends on context. That’s why you should consider the dose, your current nutrition habits, and how demanding your training is. For example, a marathon runner and a powerlifter won’t get the same value from the same electrolyte protocol. 

Tier 2 — Situational or Moderate Evidence

This tier has ingredients with real benefits but offers more conditional support. 

• Citrulline: Useful for those chasing better pumps and improved endurance during their training [6]
• Nitrates: Good option for endurance athletes looking to boost blood flow and exercise efficiency [7]. 
• Collagen: Might help support joint health or connective tissue recovery [8].
• Greens: Relevant for those who struggle to hit their daily vegetable intake through whole foods. 
• Adaptogens: May appeal to those managing high stress levels or looking to support recovery and hormonal balance [9].

Keep in mind that these aren’t necessarily foundational to everyone. It depends on what you are looking to get out of the supplement (like increased muscle pumps or reduced stress). They’re worth considering once your basics are covered, not before. 

Tier 3 — Emerging or Limited Evidence

The last tier is those that are emerging or have limited evidence. These supplements include: 

• Nootropics: These are meant to help improve cognitive function, supporting your focus, memory, and mental clarity [10].
• Longevity compounds: Substances like NMN or resveratrol, which are marketed to help slow aging and extend healthspan [11].
• Many proprietary blends: Multi-ingredient formulas where the exact dosages are hidden behind a “blend,” making it hard to assess their true effectiveness [12]

Some of these ingredients have genuinely promising research. But promising isn’t the same as proven. It’s worth distinguishing between ingredients with early, exciting data and ingredients with the long-term, replicated research you see for Tier 1 ingredients. 

Now, while proprietary blends might include well-researched ingredients (like those in Tier 1), be cautious because you don’t truly know the dosage. And with supplements, dosage is everything. 

We go over a more detailed breakdown of these ingredients here.

The Foundational Layer: Start Here

Before adding anything, it’s important to understand what makes a supplement “foundational.” These ingredients are tier 1: backed by decades of research, used consistently across populations, and showing reliable results. 

While these are foundational supplements with substantial research behind them, whether you need to supplement them depends on your diet, training, and individual needs.

Protein

How much protein you eat matters far more than whether it comes from food or a shaker bottle. Protein powder isn't mandatory or magical, but it can be a handy supplement when you can't meet your protein needs. 

The daily recommended intake is based on weight. According to the International Society of Sports Nutrition, most exercising adults should aim for 1.4 to 2.0 grams of protein per kilogram of body weight [1].

This means that someone who weighs 80 kilograms (176 lbs) should eat 112 to 160 grams of protein. For some people, this intake is easy to get from foods, but for others it’s a hassle. That’s where protein supplements can help. 

Protein powders come in different types:

• Whey protein digests quickly and offers a complete amino acid profile, making it a popular option post-workout
• Plant-based options like pea, rice, or blends can provide enough protein while still meeting your amino acid needs.
• Casein protein digest more slowly, making them ideal for general use or an overnight snack. 

Browse our protein supplements collection to find the format that fits your diet and training style. 

Creatine

Creatine is one of the most researched and well-established performance supplements available. It’s associated with improvements in strength, power output, and training capacity. Newer research also suggests possible benefits for cognitive function [2, 13].  

While creatine comes in different forms, the standard option is creatine monohydrate. It’s the most extensively studied version and typically the most cost-effective. 

A typical daily intake falls between 3-5 grams, taken consistently rather than timed around workouts. 

Explore our creatine supplements collection to find the right option for your routine. 

Core Nutrients to Consider

While several micronutrients matter, three often come up in supplement conversations: vitamin D, omega-3s, and magnesium. 

• Vitamin D: It often depends on blood levels, sun exposure, and vitamin D intake through foods [14].
• Omega-3s: Consider them if your diet includes little fatty fish or you follow a plant-based diet [14]. 
• Magnesium: Needs vary depending on diet quality, training, volume, and individual factors [15]. 

Keep in mind that none of these are an automatic must-have for everyone. They’re worth evaluating against your own diet and, when appropriate, discussing them with a healthcare provider.

Goal-Based Supplements: Build on the Foundation

Once you have your foundation covered, you can start considering adding supplements based on what you’re actually trying to accomplish. This is where your supplement selection becomes personalized.

As we go through the supplements below, we'll be going through ingredients rather than strictly categories. This is because some, such as "pre-workouts, may have products with vastly different ingredients.

Type/Goal	Why To Take	Common Ingredients
Increased Energy	Boost alertness, reduce fatigue, and maintain energy during workouts or daily activities.	Caffeine, B Vitamins, Rhodiola, L-Theanine
Greater Mental Focus & Clarity	Support concentration, mental alertness, memory, and cognitive performance.	Alpha-GPC, L-Tyrosine, Lion's Mane, Citicoline
Strength & Performance	Improve strength, power output, muscular endurance, and high-intensity exercise capacity.	Creatine, Beta-Alanine, Sodium Bicarbonate, HMB
Fuller Muscle Pumps	Promote blood flow, nitric oxide production, and muscle fullness during training.	L-Citrulline, Nitrates, Glycerol, Nitrosigine
Better Recovery	Support muscle repair, reduce soreness, and help maintain training performance.	Protein, Creatine, EAAs, Tart Cherry
Deeper Sleep	Support relaxation, sleep onset, and overall sleep quality.	Magnesium, Melatonin, L-Theanine, Ashwagandha
Improved Hydration	Maintain fluid balance, replace electrolytes, and support performance during prolonged exercise.	Sodium, Potassium, Magnesium, Glycerol, Taurine
Health & Wellness	Address nutritional gaps and support immune function, digestive health, and general well-being.	Multivitamins, Vitamin D, Omega-3s, Probiotics, Greens

Energy

If your main goal is to feel more alert and capable during training, a few targeted ingredients tend to cover the most bases. 

Caffeine is the most popular, and most effective, supplement used for energy. It stimulates the central nervous system, increasing alertness and reducing perceived fatigue. This can help you feel more energetic and sustain exercise performance [3].

L-Theanine when combined with caffeine, L-theanine may promote alertness and attention while moderating some of caffeine's unwanted effects [16].

L-Tyrosine helps produce dopamine and norepinephrine and may help maintain cognitive performance during stressful or demanding situations [17].

Various Adaptogens, such as ashwagandha and rhodiola, may help with fatigue and stress, although effects and evidence vary considerably by ingredient [9].

B-Vitamins, particularly B6 and B12, play essential roles in converting carbohydrates, fats, and proteins into usable energy. However, taking extra B vitamins doesn't necessarily increase energy if you're already getting enough.

Explore our energy supplements collection to find the best supplement to cover your energy needs. 

Recovery & Sleep

Recovery and sleep supplements focus on muscle repair, reducing muscle soreness, and improving overall recovery. However, treat them as two different categories. This can help you choose the option you need based on what’s actually limiting your progress. 

Some of the most popular recovery supplements contain your foundational supplements along with other beneficial choices.

Protein provides a complete amino acid profile needed to repair exercise-damaged muscle tissue and support muscle protein synthesis [1].

BCAAs provide leucine, isoleucine, and valine, three essential amino acids. Some studies suggest reduced muscle soreness, but benefits are inconsistent. EAA products provide all nine essential amino acids, although neither is usually necessary when adequate complete protein is consumed.

Creatine helps replenish cellular energy and may support recovery by improving glycogen restoration and reducing some markers of exercise-induced muscle damage [2, 13].

Tart Cherry is gaining popularity as it’s rich in polyphenols that may help reduce exercise-induced inflammation and DOMS. This can possibly help return muscle function quicker [19].

Sleep-focused supplements are compounds that may help improve the overall quality of your sleep and duration. This includes ingredients such as: 

Magnesium supports normal nervous-system function and may improve certain aspects of sleep, particularly in people with inadequate magnesium intake [20].

Melatonin helps regulate your sleep-wake cycle and can make it easier to fall asleep, particularly when your circadian rhythm is disrupted [21].

Ashwagandha may help improve sleep quality and reduce stress, which can make it easier to relax and sleep [22].

L-Theanine may promote relaxation and reduce stress without causing strong sedation, potentially supporting better sleep quality. It’s commonly paired with caffeine [23].

Hydration & Endurance

Hydration supplements help maintain fluid balance, replace electrolytes lost through sweat, and support muscle function during exercise. They're especially useful during prolonged workouts, intense training sessions, or exercise in hot and humid conditions.

Electrolytes help maintain hydration and normal muscle and nerve function. During significant sweat loss, replacing electrolytes can help prevent dehydration-related declines in performance and perceived energy.

For example, someone training for an hour in a climate-controlled gym has very different hydration needs than someone running a summer half-marathon

Glycerol is a lesser-known ingredient that's becoming increasingly popular for its potential hydration benefits. Commonly used in endurance sports and increasingly found in gym-focused supplements, glycerol helps the body retain fluids and supports hydration. This can potentially improve endurance and performance during prolonged exercise, particularly in hot conditions.

Taurine may also support hydration by acting as an osmolyte, helping regulate fluid balance, cell volume, and cellular hydration.

Explore our electrolyte and hydration supplement collection to help you stay hydrated and perform your best. 

Improved Pumps And Blood Flow

Ingredients for performance and improved pumps are those 

L-Citrulline is used to increase nitric oxide production. This can support blood flow and muscle pumps, with potential benefits for muscular endurance.

Nitrates, commonly found in beetroot extract, help increase nitric oxide production in the body, promoting blood flow and oxygen delivery to working muscles. This may improve exercise efficiency, endurance, and performance during high-intensity exercise, while also supporting muscle pumps during resistance training.

Glycerol, while historically been used in endurance exercise, has become increasingly popular in pre-workouts for the gym. It helps the body retain fluids and supports muscle hydration, potentially contributing to fuller pumps, although the evidence for this specific benefit is still limited.

Immune & Daily Wellness

Immune and daily wellness supplements cover a broad range of products designed to support your body’s everyday functions, from immune defense to digestive health and overall vitality. 

Unlike protein or creatine, these supplements are best approached as goal- or situation-specific additions rather than universal foundations. 

Green powders are worth considering if your diet is consistently low in vegetables or you’re looking for a convenient way to fill micronutrient gaps (like when you are traveling). 

Gut-health products, like certain probiotics, may help with specific digestive conditions, depending on the strain and dose. Digestive enzymes have targeted uses, such as lactase for lactose intolerance, and should be selected based on the underlying issue.

Mushroom supplements such as lion’s mane, reishi, and chaga are gaining popularity due to their potential effects on cognitive health and immune-supporting benefits [9].

Keep in mind these are more specific and many are for non-sports needs. Therefore, don't automatically think you need these and look at your overall health needs. Get your foundational nutrition in order, and then layer these in where they make sense to help you reach your goals. 

Browse our gut-health, mushroom, or greens and superfoods collection to help you find the one that might cover your needs. 

Stim Vs Stim-Free Pre-Workouts

"Stim" and "Stim-Free" refers to two broad categories of pre-workout and essentially define if they have stimulants. This includes things like caffeine or coffee bean.

Both stim and stim-free pre-workouts can contain the same performance-enhancing ingredients; other than the inclusion of a stimulant, their formulas can look identical. The key is choosing a formula with effective doses rather than simply looking for the longest ingredient list.

Check out our full-breakdown here.

How to Read a Supplement Label

Once you know what category of supplement you’re looking for, the next skill is to learn how to read a supplement label. This helps you choose an effective product over a weak one. 

Dose Matters More Than Ingredient Count

Most pre-workout ingredients have a minimum dose of effectiveness; this simply means that you need to consume a certain amount to receive benefits. 

A supplement with three well-dosed, evidence-backed ingredients often outperforms one with 15 different ingredients at negligible amounts. A long ingredient panel can look impressive, but If their ingredients aren’t dosed effectively, their effectiveness is impacted. 

For example

• Pre-Workout A = 300mg Caffeine + 6,000mg Citrulline 
• Pre-Workout B = 10mg Caffeine + 50mg Citrulline Malate +20mg Beta-Alanine + 10mg Creatine Monohydrate + 5mg L-Tyrosine + 10mg Taurine + 5mg Betaine Anhydrous.

Even though Pre-workout B has 3X more ingredients, they’re all terribly underdosed so Pre-Workout A is the better product.

Therefore, when evaluating a product, compare the listed amount of each active ingredient with the dose supported by research. You also need to be careful with proprietary blends, especially unknown brands.

Without transparency, it’s difficult to know whether you’re getting a meaningful dose of anything you’re taking. 

Active Ingredients vs. Other Ingredients

Every supplement label includes a Supplement Facts panel that lists the active ingredients and their amounts. Below or beside that, you’ll typically find “other ingredients,” such as flavorings, sweeteners, capsule material, and flow agents that help with manufacturing but don’t contribute to the supplement’s effect. 

When you evaluate a product, focus on the ingredients relevant to its intended purpose, rather than being swayed by a long list of inactive additions or the marketing claims on the front of the supplement. 

Third-Party Testing & Certifications

Independent testing can help verify label accuracy and screen for specified contaminants, depending on the program. Athletes in tested sports should look for a sport-specific certification that includes banned-substance screening. This matters even more for anyone who’s competing in tested sports. 

How to Build a Supplement Stack

Now that you know the foundation supplements, understand what to look for in them; here’s how you can put it all together. 

A Simple 3-Step Framework

1. Build the foundation. Address your diet first, then you can fill in any obvious supplementation gaps. This usually includes protein, creatine, and any micronutrients missing from your diet. In some cases, you may want to get bloodwork done to confirm whether you need to supplement (like with vitamin D).
2. Add one goal-specific supplement. Choose it based on your primary goal, which can be performance, recovery, hydration, or sleep. Add one at a time to make it easier to tell whether it’s working for you.  
3. Reassess after 4–6 weeks. Evaluate whether the addition is providing enough value to justify keeping it in your routine, or whether it’s time to adjust. 

How to Stack Supplements Safely

While you can combine supplements, it does require a bit of attention to avoid overlapping: 

• Check for ingredients that show up in more than one product you’re taking, like caffeine. 
• Track your total caffeine intake across products like pre-workouts, coffee, and other caffeinated beverages (even black tea). 
• Avoid accidentally doubling up on beta-alanine, nitrates, vitamins, minerals, or other shared active ingredients. 
• Factor in any medications, health conditions, or other individual contraindications. 
• Consider using single-ingredient products when possible.

Remember never to add a supplement without talking with your healthcare provider first. They can guide you on whether the supplement is right for you, especially if you have an underlying condition or take chronic medications. 

Consistency Matters More Than Novelty

Supplements that rely on regular intake (like protein and creatine) only deliver results when you take them consistently over time. Constantly swapping out established basics for whatever ingredient is trending tends to affect your progress rather than accelerate it. 

The most effective stacks usually are often the simplest ones, and those you consistently take for months. Once you’ve found a routine that works, a subscription with your favorite supplements can help you stay consistent without having to think about reordering, and it can save you money over time.

Quick Guide To The Best Supplement Stacks

Here’s a quick guide to the best supplement stacks for different goals. These can work well with any of the brands in our collection page.

The Foundation Stack

A foundation stack covers the basics before adding supplements for more specific goals. The emphasis should be on filling nutritional gaps and using supplements with broad evidence for supporting health, training, and recovery.

• Protein
• Creatine
• Omega-3s
• Vitamin D
• Magnesium

Energy supplements primarily work by increasing alertness, reducing perceived fatigue, or supporting cognitive performance. They can be particularly useful before training or during mentally demanding periods.

• Caffeine
• L-theanine
• L-tyrosine
• Electrolytes
• B vitamins when intake is inadequate

Sleep Stack

Sleep supplements can support different aspects of sleep, including relaxation, sleep onset, and sleep quality. Which ones make sense depends on why you're having trouble sleeping in the first place.

• Magnesium
• Melatonin
• L-theanine
• Ashwagandha

These supplements are commonly used to support connective tissue and joint health, particularly among people who train frequently or place substantial repetitive stress on their joints.

• Collagen or gelatin
• Vitamin C
• Omega-3s
• Curcumin

Frequently Asked Questions

Which supplements are actually worth taking?

It depends on your diet and goals. Protein, creatine, and micronutrients you’re lacking are a good starting point, followed by goal-specific supplements like pre-workouts or electrolytes.

How do I know if a supplement is high quality?

Look for transparent labels, evidence-based ingredient doses, reputable manufacturers, and third-party testing. Check our full certification breakdown to learn what different certifications mean.

Can I take multiple supplements together?

Usually, but check for overlapping ingredients such as caffeine, beta-alanine, vitamins, and minerals. Combining products can unintentionally push your total intake beyond recommended amounts, so review your full stack and consult a healthcare professional when necessary.

Do I need to cycle supplements?

It depends on the ingredient. Some, like caffeine, may benefit from taking periodic breaks to manage tolerance. Others, like creatine, work best when taken consistently. Regular intake helps maintain elevated muscle creatine stores, which gradually return toward baseline after supplementation stops.. 

The Bottom Line

Supplements work best as a supporting layer, not a substitute for a solid diet and consistent training. Start with the basics: protein, creatine, and any micronutrients missing from your diet before adding anything else. 

From there, choose additions based on specific, defined goals, and prioritize evidence, effective doses, transparent labels, and quality testing over hype or ingredient count. 

Just remember that when you're building a stack, complication doesn't mean effective. In reality, the best stack is the one that meets your needs. For some, that may mean a full line-up. For others, it may just mean some protein and creatine. So, if you are ready to build yours, subscribe and save on the products that make up your core routine.
