Lin Kai is a licensed pharmacist with 17 years at the hospital dispensary counter, and author of The Pharmacist's Guide to Supplements That Actually Work and The Pharmacist's Guide to Herbal Supplements. He writes to help you separate science from marketing — one pill, one article at a time.

Most supplement advice online comes from people who have never held a prescription bottle. His doesn't. Every article here goes through the same evidence check he does at work: Cochrane reviews, FDA and NIH documents, clinical trial data — read critically, explained plainly.

Working on a supplement product, label, or health article yourself? He offers independent supplement-label review and evidence-checking for small brands, writers, and businesses — a licensed pharmacist's second pair of eyes before your claims go public. https://www.fiverr.com/kailin_pharmaci
