Independent supplement research analyst specializing in metabolism support and weight loss supplements. I evaluate products based on clinical evidence and safety data rather than marketing claims.
A digital nomad, travelling across the planet.
I'm Jacob O'Brien, the publisher and primary reviewer behind this website.
I started reviewing dietary supplements in 2026 after struggling to find honest, research-based information that wasn't just marketing disguised as reviews. This led me to develop a systematic evaluation framework based on clinical evidence rather than promotional claims.
I am NOT a medical doctor, registered dietitian, or licensed healthcare professional. I am an independent publisher who specializes in analyzing publicly available supplement research and consumer safety data.
Always consult your healthcare provider before using any dietary supplement.
Areas of Focus:
- Weight loss supplements
- Metabolism support products
- Thermogenic fat burners
- Supplement ingredient safety
- Clinical research analysis
What I Evaluate:
For each supplement I review, I analyze:
- Ingredient transparency and dosage disclosure
- Clinical evidence from peer-reviewed research
- Safety profiles and potential side effects
- Customer experience patterns across platforms
- Business practices and refund policies
- Marketing claim accuracy
This focused specialization allows me to develop deep expertise in metabolism-related supplements rather than superficial coverage of all supplement categories.
I follow a systematic evaluation framework for every product:
1. Research ingredient profiles using PubMed and NIH databases
2. Compare product dosages to amounts used in clinical studies
3. Review safety data from FDA and medical institutions
4. Analyze 50-200+ customer reviews for real-world patterns
5. Verify business transparency and refund policies
6. Assess cost-benefit vs. similar products
This process takes 8-15 hours per comprehensive review.
