At 50mg per full dropper (1ml), Lazarus Naturals High Potency, THC-Free Isolate Tincture is great for day and nighttime relief for anyone looking to avoid all other cannabinoids. If you want a Cannabidiol (CBD) tincture strictly this is the one for you. Our recommended daily use for all our tinctures is 25mg per-day — 12.5mg in the morning and 12.5mg 2 hours before bed. Using hemp grown on their farms, Lazarus Naturals renders CBD-rich extract from the plant using an ethanol-based process. Then they refine the extract via fractional distillation and crystallization into CBD isolate. All Lazarus CBD tinctures are third-party tested for potency, pesticides and heavy metals. Their testing process ensures they offer a product that is natural, safe and consistent. All test results are available on their website lazarusnaturals.com under the Test Results tab for each product.
