3. The Technical Review Process
At HSN Blog, no content is published without undergoing a technical review and scientific validation process. Our aim is to ensure that every article meets the highest standards of quality, accuracy and transparency.
Scientific research
Each piece of content begins with a review of primary sources and high-quality scientific literature, including:
- Meta-analyses.
- Systematic reviews.
- Randomised controlled trials.
- Official position statements and scientific consensus statements.
We always prioritise the most up-to-date scientific evidence with the strongest methodological support.
Accessible yet rigorous scientific writing
We translate scientific evidence into content that is clear and useful for readers, while always maintaining terminological accuracy and avoiding exaggerated or scientifically unsupported claims.
Our approach aims to balance:
- Clarity and accessibility.
- Technical rigour.
- Evidence-based practical application.
Technical validation
Before publication, articles are reviewed by our Expert Committee, led by Carlos Sánchez (R&D Department) and Alfredo Valdés, who oversee the scientific accuracy, technical consistency and overall quality of the content.
Continuous updates
Science is constantly evolving. We therefore maintain an active commitment to reviewing and updating older articles whenever relevant new evidence emerges that may modify or expand upon the information published.
4. Our Sources of Information
All HSN Blog content is developed using an evidence-based approach, drawing on internationally recognised scientific sources and leading specialist databases.
We regularly use sources such as:
- PubMed / MEDLINE — National Library of Medicine.
- EFSA — European Food Safety Authority.
- Cochrane Library.
- JISSN — Journal of the International Society of Sports Nutrition.
- Google Scholar.
These platforms provide access to peer-reviewed research, official scientific position statements and publications of high academic relevance.
5. Editorial Independence and Transparency
Although HSN is a manufacturing brand, our editorial policy requires authors to discuss the benefits and limitations of each ingredient based exclusively on the available scientific studies, maintaining a neutral approach that safeguards readers’ trust.
Our commitment is to provide objective, transparent and evidence-based information, regardless of commercial interests or market trends.
Therefore:
- We do not make claims without scientific support.
- We highlight the limitations of studies where applicable.
- We clearly distinguish between strong evidence, preliminary evidence and expert opinion.
6. Our Commitment to Corrections
Honesty and transparency are essential parts of our editorial philosophy.
If we identify a technical error or a study becomes outdated due to new evidence, we are committed to updating the content promptly to ensure that the information we provide remains rigorous, useful and reliable.
If you identify an error in any of our articles, please let us know by contacting us at the relevant email address.
