Supplements can be useful. Sometimes they’re even necessary. But figuring out if, when, and why you should use them is a more complicated question than most headlines, influencers, or supplement companies want to admit. In a perfect world, we’d get all the micronutrients, minerals, and performance-optimizing compounds we need from real food, sunlight, sleep, and clean living. In the real world, though—where stress is high, schedules are full, and food quality varies—strategic supplementation can fill gaps, enhance recovery, improve long-term health, or support performance.
But here’s the problem: the supplement space is a minefield. Outdated “bro science,” influencer hype, fairy-tale claims, and straight-up lies have created a noisy mess that makes choosing the right supplement—if you even need one—much harder than it should be. And remember: no two bodies are exactly alike. Your age, gender, activity level, medical history, diet, goals, and lifestyle all influence what your body might be missing (or absorbing poorly). Supplementation isn’t a one-size-fits-all solution—it’s a strategy. That strategy should begin with lab work, conversations with qualified professionals, and clear priorities.
Disclaimer:
This guide is not medical advice or a prescription. It’s an information tool designed to help you better understand what supplements may—or may not—support your personal health, performance, or longevity goals. Before starting any new supplement, consult with a qualified healthcare or functional nutrition professional, especially if you have preexisting conditions, take medications, or are managing complex health goals.
This ranked list attempts to prioritize supplements based on their value for longevity, healthy aging, recovery, and athletic performance—in that order. If your priorities are different, the ranking of these supplements might change or look quite different.
Each supplement is evaluated using scientific literature (not market hype), considering:

These commonly marketed supplements either lack strong evidence of benefit, are redundant, or may even pose risks. They don’t make the top 20 and generally aren’t worth your money—or your hope.
1. Glucosamine + Chondroitin
🧩
Claim: Joint repair and cartilage protection
❌
Verdict: Multiple large studies show minimal to no benefit beyond placebo. Any mild effect is likely anecdotal or driven by industry bias.

NEJM.
https://doi.org/10.1056/NEJMoa052771
2. Branched Chain Amino Acids (BCAAs)
🧩
Claim: Boosts recovery and muscle growth
❌
Verdict: If you consume adequate total protein, BCAAs offer no additional benefit and are a waste of money.

3. Testosterone Boosters (Tribulus, Fenugreek, etc.)
🧩 Claim: Raise testosterone naturally and build muscle
❌ Verdict: Strong placebo effect but little measurable improvement in T levels or performance in healthy men.

The best supplement plan isn’t the one with the most bottles—it’s the one that matches your physiology, lifestyle, and goals. Testing (like blood panels for vitamin D, ferritin, CRP, lipids, etc.) can reveal where your body actually needs support.
And with your test results in hand, the most likely best course of action is to reevaluate your nutrition, your sleep, your exercise, your stress management, and your relationships. And then decide if you need a supplement to fill any gaps.
Partnering with a health professional can help you:
I encourage you to learn more and be curious about topics like these. It's easy to get misled by what "experts" have to say and take it as fact. But with very few exceptions, scientists with the actual credentials and research are rarely on Instagram, YouTube, or TV. Sure, there are people like me who are the messengers and evangelists of this sort of information. However, my filter may come with biases, agendas, inaccuracies, or ignorance. As Timothy Leary, Ben Franklin, and Socrates used to say, Question Authority.
The sources used to support these rankings are easy to find. A Google search that begins with "NIH" (National Institute of Health) followed by whatever you're curious to learn about often leads you to a list of articles addressing your questions. ChatGPT can answer your questions and curiosities in more of a conversational manner but it's wise to ask it for its sources and fact check it. It's usually right but sometimes it's wrong.
Good luck! And I hope you found this interesting and made you more curious.
