In this premiere episode of From A to Zinc, I sit down with Stanford nutrition expert Dr. Christopher Gardner to unpack the basics of dietary supplements — what they are, what they aren’t, and what you absolutely need to know before adding them to your routine.

From vitamins and minerals to probiotics and herbal extracts, we explore the six core supplement categories, demystify common myths, and get real about what supplements can (and can’t) do for your health. Dr. Gardner shares practical, research-backed advice on how to approach supplementation wisely — always starting with food first.

You’ll also learn:
•Why context is everything when it comes to nutrition
•The difference between fat-soluble and water-soluble vitamins
•Why not all supplements are created equal (and how to verify quality)
•Surprising facts about vitamin B12, D, and more

Final takeaway? “It’s not about chasing the next magic vitamin — it’s about your whole lifestyle.”
