The Truth About Supplements: Which Ones are Worth Your Money (and Which are Just Hype)

The world of health and fitness supplements is a jungle. The shelves are packed with colorful containers promising everything from instant fat loss to massive muscle gains. It’s estimated that consumers spend billions every year on pills, powders, and potions, often without seeing any real benefit.

For anyone committed to long-term health, it’s important to understand the hierarchy of results:

1. Diet and Lifestyle: This is the foundation (sleep, real food, consistent training). This is 90% of your results.

2. Supplements: These are the finishing touches, designed to fill small gaps or slightly enhance performance. This is the remaining 10%.

If your foundation is shaky, no amount of supplements will save you. But once your core diet and training are solid, a few key supplements can provide real, evidence-based benefits.

Here is an honest breakdown of which supplements are genuinely worth your money and which ones are mostly marketing hype.

The Tried-and-True (The Essentials)

These supplements have the most scientific evidence and are generally safe and effective for filling common nutritional gaps or boosting performance.

1. Protein Powder (Whey, Casein, or Plant-Based)

• What it does: Provides a quick, convenient source of protein to support muscle repair and recovery (especially useful after a workout or when you need a high-protein snack).

• When it's worth it: When you struggle to hit your daily protein goal (aim for about 0.7–1 gram per pound of body weight).

• The Hype Check: Skip the fancy "muscle-building blends" and focus on a simple, high-quality powder with minimal added sugars.

2. Creatine

• What it does: This is the most studied and proven supplement for athletic performance. It helps your muscles generate more energy during short bursts of high-intensity exercise, leading to greater strength, power, and muscle mass over time.

• When it's worth it: If you do any type of resistance training (lifting weights). It works for almost everyone and is very safe.

• The Hype Check: You only need 3–5 grams per day. Don't worry about "loading" phases; consistency is key.

3. Vitamin D

• What it does: Essential for bone health, immune function, and mood regulation. Many people, especially those who live in northern climates or spend a lot of time indoors, are deficient.

• When it's worth it: If your blood work shows you are deficient, or if you get very little direct sun exposure (which is common, especially in the winter months).

• The Hype Check: Check with your doctor to find the right dosage for you, as taking too much can be harmful.

The "Maybe Worth It" (Depends on Your Diet)

These supplements are useful if your diet is lacking in a specific area, but they aren't necessary for everyone.

1. Omega-3 Fatty Acids (Fish Oil)

• What it does: Provides EPA and DHA, essential fats that reduce inflammation, support heart health, and contribute to brain function.

• When it's worth it: If you don't eat oily fish (like salmon, mackerel, or sardines) at least two times per week. The anti-inflammatory benefits can be great for recovery.

• The Hype Check: Look for a supplement that clearly lists the amounts of EPA and DHA on the label, and ensure the product is third-party tested for purity (to check for heavy metals).

2. Magnesium

• What it does: Helps relax muscles, supports hundreds of chemical reactions in the body, and promotes better sleep (as we discussed in a previous article!).

• When it's worth it: If you frequently experience muscle cramps, have high stress, or struggle with sleep (choose magnesium glycinate before bed).

• The Hype Check: Magnesium oxide is cheap but poorly absorbed. Choose glycinate or malate for better results.

The Hype Zone (The Budget Killers)

These supplements usually aren't worth the money for the average person and often make huge claims that the science simply doesn't support.

1. BCAA (Branched-Chain Amino Acids)

• The Reality: These three specific amino acids are important, but if you are already consuming enough protein (especially whey, which is rich in BCAAs), taking extra BCAAs won't provide any added benefit. They are mostly expensive, flavored water. Eat protein instead.

2. Fat Burners / Metabolism Boosters

• The Reality: These usually contain a huge dose of caffeine and various herbal extracts. They might make you feel jittery (like you're burning fat), but they do little to actually boost your metabolism or cause significant, lasting weight loss. They often carry risks like increased heart rate and anxiety. Focus on clean eating and consistent training.

3. Detox Teas / Cleanses

• The Reality: Your body has its own detox system: your liver and kidneys. These supplements are often just expensive laxatives and diuretics that cause temporary weight loss (water weight) and can be harmful to your digestive system. Focus on fiber and hydration.

The Final Word: Food First

No pill or powder can outsmart a poor diet. Supplements are exactly what the word implies: they are meant to supplement, or complete, a healthy, whole-food diet. If you are sleeping well, eating enough protein and vegetables, and training consistently, then consider adding one or two evidence-based supplements. If you aren't doing the basics, save your money and invest it in high-quality groceries instead.

The Magic of Magnesium: Why This Mineral Is Key to Better Sleep and Muscle Relaxation

When you think about health and fitness, you probably focus on protein, carbs, and maybe big minerals like calcium. But there's a quiet superhero that's essential for almost every function in your body: magnesium.

Magnesium is a mineral that your body uses in over 300 different reactions. Think of it as the "spark plug" that powers everything from your nerves and muscles to your bones and heart. It plays a huge role in energy creation and, most importantly for athletes and busy people, recovery and relaxation.

Unfortunately, many people aren't getting enough magnesium from their diet—some studies suggest up to two-thirds of the population is deficient. Even if you eat healthy, modern farming practices have sometimes led to less magnesium in the soil, meaning less in your food.

If you’re having trouble sleeping, getting muscle cramps, or feeling stressed and tense, low magnesium might be part of the problem. Here’s why this mineral is so magical for your fitness and well-being.

Magnesium: The Ultimate Muscle and Nerve Relaxer

When you work out, your muscles contract (tighten) to lift weights or move your body. After the workout is done, those muscles need to relax and release the tension. This is where magnesium steps in.

• Countering Calcium: When a muscle contracts, it’s often triggered by the mineral calcium. Magnesium works like a dimmer switch, blocking calcium from doing its job so the muscle can finally relax. Without enough magnesium, your muscles can stay slightly contracted, which can lead to cramps, tightness, and restlessness.

• Fighting Aches: Magnesium helps control inflammation in the body. By reducing the overall stress response, it can help cut down on the everyday aches and pains that come from hard training or just a busy life.

If you’ve ever had a painful Charley horse or unexplained muscle twitching, a lack of magnesium could be the culprit.

Magnesium: Your Natural Sleep Aid

Sleep is when your body does all its heavy lifting for recovery, and magnesium is a powerful tool for getting deeper, more restful sleep.

• Calming the Brain: Magnesium helps regulate neurotransmitters (chemical messengers) in your brain. Specifically, it helps activate the parasympathetic nervous system, which is the body’s "rest and digest" system. This calms your brain down and gets you ready for sleep.

• The GABA Connection: Magnesium binds to GABA receptors in the brain. GABA is the main calming neurotransmitter, it's what tells your brain to slow down. By boosting GABA activity, magnesium acts like a natural sedative, helping you fall asleep faster and stay asleep longer.

• Fixing Restless Legs: Many people who suffer from restless leg syndrome (that twitchy feeling that keeps you up) find relief with magnesium, allowing for a quieter, more still night's sleep.

Magnesium in Your Diet: Where to Find It

Before reaching for a supplement, the best place to get magnesium is from whole foods. Focus on these powerhouses:

• Dark Leafy Greens: Spinach and kale are kings of magnesium. One cup of cooked spinach can provide nearly 40% of your daily needs.

• Nuts and Seeds: Pumpkin seeds, chia seeds, and almonds are excellent sources. A small handful makes a perfect high-protein, high-magnesium snack.

• Legumes: Black beans, lentils, and chickpeas are budget-friendly and nutrient-dense.

• Whole Grains: Buckwheat and whole wheat are good sources, making whole-grain bread or oatmeal a smart choice.

• Dark Chocolate: Yes, a little bit of high-quality dark chocolate (70% cocoa or higher) is a delicious source of magnesium!

Should You Supplement?

If your sleep is poor, your stress levels are high, or you train intensely, a supplement might be a good idea. However, it’s important to know the different types of magnesium, as they do different things:

• Magnesium Glycinate: This is the most popular form for sleep and relaxation. It's easily absorbed and tends to be gentler on the stomach. Take it an hour before bed.

• Magnesium Citrate: This is best known for helping with constipation, as it draws water into the bowels. It's not typically recommended as the primary form for daily muscle or sleep support.

• Magnesium Malate: This form is often suggested for energy production and muscle pain. It may be better taken earlier in the day.

Like any essential ingredient, the magic of magnesium isn't in taking a huge dose, but in getting a consistent, healthy amount every day. When your magnesium levels are balanced, you’ll feel the difference: less muscle tension, a calmer mind, and deeper, more restorative sleep—all leading to better workouts and a healthier life.

Easy Tips to Hit Your Protein Goal

Getting enough protein each day is key if you want to build muscle, lose fat, or just feel better. But let’s be honest, sometimes it feels hard to get it in, especially if you’re busy.

The good news? It doesn’t have to be. Here are 5 simple tips to help you hit your protein goal every day without overthinking it. These ideas are simple, quick, and perfect for anyone on the go.

Why Protein Matters

Protein helps your body repair muscles after workouts, keeps you full, and gives you energy. Most people need about 0.36 to 1.0 grams of protein per pound of body weight daily, depending on their goals and level of activity. For example, if you weigh 150 pounds, aim for 105 to 150 grams of protein a day. These tips will make it easy to hit that number!

5 Easy Tips to Get More Protein

1. Add Protein to Breakfast
   Instead of starting with a carb-heavy breakfast (cereal, toast, etc…), start your day strong with a protein-packed breakfast. Try eggs (one large egg has 6 grams of protein) or blend a quick smoothie with protein powder (20-25 grams per scoop). Mix in some fruit and milk for flavor. It takes just 5 minutes to make!

2. Use a Protein Supplement
   Whole foods are great, but protein shakes and bars can help fill the gaps. They’re fast, easy, and perfect when you're busy. Look for whey isolate or plant-based protein powders for easy digestion, low-sugar protein bars or even ready to drink shakes.

3. Include Protein in Every Meal and Snack
   Don’t save all your protein for your ‘big meals’ like lunch or dinner. Instead, build your meals and snacks around your protein. It’ll help your body use the protein more efficiently (since you can only absorb about 35 to 50g of protein at a time) and keep you feeling fuller longer.

4. Batch Cook or Prep Protein in Advance
   When life gets busy, fast food wins, unless you’re ready ahead of time. Cook protein in bulk so you can grab and go. For example, grill or bake your chicken breasts for the week or hard-boil a dozen eggs. Spending about 30 to 60 minutes on the weekend meal prepping can save you hours (and stress) during the week. You can also keep grab-and-go snacks handy like yogurt (pro-tip: check out higher protein versions of Ratio or Oikos with up to 25g of protein per 5.3oz serving), beef jerky or protein bars. Stash some in your car, bag or desk so you’re never caught off-guard.

5. Track Your Protein (At Least for a Week)
   Most people think they’re getting enough protein, but when they track it they’re surprised. Try using MyFitnessPal or, for current clients, the built-in meal tracker with your Legacy Fitness & Nutrition program app. You’ll learn a lot from even a few days of logging. Work with your coach to figure out your goals to get the right amount of protein for you.

BonUS: High-Protein Foods That Are Easy to Prep or Grab

Here’s a list of protein-rich foods that are simple to prepare or buy:

• Yogurt: 15-25 grams per 5.3-ounce cup (again check out Ratio or Oikos for high protein options). Buy single-serve cups for convenience.

• Eggs: 6 grams per large egg. Boil a batch for the week.

• Chicken Breast: 25 grams per 4-ounce serving. Grill or bake in bulk.

• Canned Tuna: 25 grams per 5-ounce can.

• Protein Bars: 15-20 grams per bar. Look for low-sugar options.

• Edamame: 17 grams per cup. Steam and sprinkle with salt for a snack.

• Cottage Cheese: 25 grams per cup.

Final Thoughts

Hitting your protein goal doesn’t have to be hard. With these tips, you can eat enough protein even on your busiest days. Keep it simple, plan ahead, and choose foods you enjoy. Your body will thank you!
