L-Theanine 200 mg Capsules

Welcome. For everyone who’s supplement-curious or supplement-overwhelmed, we recommend starting with the First5 — five core nutrients that are commonly missing from even the best diets, and that almost everyone would benefit from. Closing one or all of these gaps has a profound impact on how you feel today and on long-term health. To find your foundation, take the Woodstock Quiz — it identifies which of the First5 you actually need.

Pharmacist-formulated means every product is designed with clinical judgment — not marketing trends. We focus on evidence-based ingredients, well-researched forms, and meaningful doses, while avoiding unnecessary extras. The goal is simple: products that actually support your health and fit into real life.

Yes. All of our products are third-party tested for heavy metals like lead, cadmium, and mercury, as well as contaminants like E. coli, Salmonella, yeast, and mold. Every product we recommend must meet the Supplement Quality Standard — our internal benchmark for quality, manufacturing compliance, sourcing, and value. If a product fails any part of it, we don’t sell it.

No. The First5 are foundational nutrients that many people are missing, but your needs may vary. Some people benefit from all five; others only need one or two. Our goal is to help you focus on what your body actually needs — not take more supplements than necessary.

Most foundational nutrients work gradually. Some people notice changes in energy, sleep, or digestion within a few weeks, but meaningful benefits typically develop over 4–12 weeks of consistent use. Supplements support your body over time — consistency matters more than quick results.

Foundational supplements work best when taken consistently over time, but if a product isn’t the right fit, our team is here to help you adjust your plan. Our goal isn’t to sell more products — it’s to help you build a routine that actually supports your health.
