A very cost-effective multivitamin with a wide range of essential nutrients, providing basic daily nutritional support. Its main strength is its affordability rather than superior nutrient forms or targeted benefits.
21st Century Sentry Adults (300 count) is essentially the same formulation as the 130-count version, offering a comprehensive multivitamin blend aimed at supporting overall adult health. It delivers 25 essential vitamins and minerals, generally aligning with daily recommended allowances. The primary advantage of this larger pack size is an even lower price per serving, reinforcing its position as a highly economical choice for daily nutrient supplementation. As with its smaller counterpart, the product utilizes some less absorbable forms of minerals like magnesium oxide and zinc oxide, and synthetic vitamin forms such as cyanocobalamin and DL-alpha-tocopheryl acetate. While widely popular due to its affordability and convenience, expert opinions often lean towards multivitamins with more bioavailable nutrient forms for enhanced health outcomes or addressing specific nutritional needs.
- Offers a comprehensive spectrum of vitamins and minerals to support general adult health.
- Exceptional price per serving due to the large quantity, making it highly economical for long-term use.
- High serving count (300 tablets) provides extended supply and convenience.
- Incorporates less bioavailable mineral forms (e.g., Magnesium Oxide, Zinc Oxide), which may hinder optimal absorption compared to chelated forms.
- Contains synthetic variants of certain vitamins (e.g., Vitamin B12 as Cyanocobalamin, Vitamin E as DL-Alpha-Tocopheryl Acetate) that may not be as effectively utilized by the body as their natural counterparts.
- The dosages for specific health goals are generally foundational and not optimized for therapeutic effects, which might require additional specialized supplementation.
- The inclusion of Vitamin K (Phytonadione) necessitates caution for individuals on anticoagulant medications, who should consult their physician.
- Contains iron (18mg), which can be excessive for individuals without an iron deficiency, particularly adult males and post-menopausal women, potentially leading to iron overload.

Selenium 70.0
Provides 55mcg of Selenium as Sodium Selenate. Selenium is an essential trace mineral with potent antioxidant properties, supporting thyroid health and immune system function. This is a suitable daily amount for general well-being.

Goals
General Health 75.0
This product excels in its primary purpose of supporting general health by providing a wide array of essential vitamins and minerals. Its affordability and comprehensive nature make it a practical choice for daily supplementation to address common dietary shortfalls.
Energy 70.0
The broad range of B vitamins (Thiamine, Riboflavin, Niacin, B6, Pantothenic Acid, B12), along with Iron and Magnesium, are essential for metabolic energy production. While effective in preventing deficiency-induced fatigue, dedicated energy supplements often provide higher potencies or more active nutrient forms for a more pronounced energy boost.
Bone Health 70.0
Essential components for bone health such as Calcium (400mg), Vitamin D3 (25mcg/1000 IU), Magnesium (50mg), Phosphorus, and Vitamin K are included. While the Vitamin D3 content is beneficial, the calcium dosage is moderate and magnesium relatively low for comprehensive bone density support without other dietary sources.
