About Best Selling Supplements
We are the internet's most comprehensive, independent resource for supplement and ingredient information. Our mission is to help consumers make evidence-based decisions about supplementation through transparent, unbiased, and thoroughly researched content.
Our Mission
The supplement industry generates over $50 billion annually in the United States alone, yet consumers often lack access to clear, unbiased information about what they're putting in their bodies. Marketing claims frequently outpace scientific evidence, and navigating the thousands of available products can be overwhelming.
Best Selling Supplements was founded to bridge this gap. We provide comprehensive, research-backed profiles for over 500 supplement ingredients, covering mechanisms of action, clinical evidence, optimal dosages, safety considerations, and practical recommendations.
We are not affiliated with any supplement brand or manufacturer. We do not sell supplements. Our only goal is to provide you with the information you need to make informed decisions about your health.
Our Values
Evidence-Based
Every claim on our site is backed by peer-reviewed research. We cite our sources and distinguish between strong evidence, moderate evidence, and preliminary findings.
Independent & Unbiased
We are not sponsored by any supplement company. Our brand reviews and ingredient ratings are based solely on quality, evidence, and value — never on advertising relationships.
Comprehensive
We cover every major supplement ingredient from A to Z, including vitamins, minerals, herbs, amino acids, probiotics, and specialty compounds. Each profile is a complete reference guide.
Practical
Beyond just presenting research, we translate findings into actionable recommendations. Our dosage guides, timing protocols, and stack suggestions help you apply the science to your daily routine.
