Pure Prescriptions Perfect Immune Review
Perfect Immune by Pure Prescriptions is a capsule immune formula sold as a 90 capsule bottle, with 30 servings per bottle and a suggested use of three capsules daily with a meal containing dietary fat. The page describes the formula as covering four nutrients: Vitamin A as retinyl palmitate, Vitamin C as ascorbic acid, vegan Vitamin D3 derived from lichen, and zinc citrate. The brand states that most immune formulas use low-cost, poorly absorbed forms of vitamins and minerals, and that Perfect Immune uses clinically validated forms at therapeutic doses to cover immune activation, regulation and antioxidant protection. Vitamin A is presented as supporting immune cell development and the integrity of mucosal membranes in the respiratory and GI tracts. Vitamin C is described as a water-soluble antioxidant that protects immune cells during active responses and supports collagen synthesis in mucosal barriers. Vegan D3 from lichen (Cladina rangiferina) is positioned as an alternative to lanolin-derived D3, with the page stating it has the same bioactivity. Zinc is described as required for T lymphocytes, NK cells and neutrophils, and the page says the citrate form is more bioavailable than oxide forms. The page explains that the product is designed by Dr. Devin Ryerson at Pure Prescriptions, founded in 1999, and that every batch is said to be third-party tested for purity and potency. Usage guidance recommends daily use year round rather than only when sick, and mentions higher demand periods such as travel, seasonal changes, high workload and intense training. The page suggests a timeline in which reserves rebuild in the first weeks, vitamin D3 levels rise by week four, mucosal support builds by week eight, and full benefits are expected by week twelve, while noting results vary. The Supplement Facts list per capsule shows 499.8 mcg vitamin A, 500 mg vitamin C, 8.33 mcg vitamin D, and 5 mg zinc, with the zinc listed as zinc picolinate in that table, which differs from the zinc citrate named elsewhere on the page. Other ingredients are hypromellose capsule and ascorbyl palmitate. The page states the capsule is vegetarian HPMC rather than gelatin. Pricing on the page starts at $36.00 for the 90 capsule one-time purchase, with 3 pack and 6 pack options and an auto-delivery option. The page also promotes the product as part of a doctor's protocol alongside NAC, Digestive Defense and Magnesium Glycinate, and states that the product is made in the USA.
