Review: Effective results - Cannot speak for anyone else's results, but this worked great for increasing my low vitamin D levels from the low 30s to the 50s. Taken with K2 helps with absorption. This was an alternative to taking a doctor prescribed D2 (plant based), that did not give this kind of results even after being on it for 2 years. ## Features - High Potency Vitamin D3 50,000 IU Weekly Supplement: Each capsule provides 1250 mcg (50,000 IU) cholecalciferol designed for once-weekly use to support immune health, calcium absorption, strong bones, and healthy teeth. - Supports Muscle Strength & Neuromuscular Function: Helps regulate calcium metabolism to promote muscle performance and neuromuscular health. Ideal for adults 40+ or individuals needing higher vitamin D support. - Vitamin D From Sunshine Without UV Exposure: Delivers the same active vitamin D3 form produced by sunlight, helping maintain optimal vitamin D levels for people with limited sun exposure or low dietary intake. - Clean & Allergen-Free Vitamin D3 Capsules: Free from gluten, soy, dairy, eggs, nuts, shellfish, and fish.
