Quality Vitamin C Supplement Using Stomach-Friendly Calcium Ascorbate Format

Effective vitamin C supplement with calcium ascorbate for improved digestive comfort during regular use. Good potency and value.

This review is from Amazon.com for product:

Nutricost Vitamin C with Zinc Supplement Capsules, 120 Servings - 1000mg Vitamin C, 45mg Zinc, Non-GMO, Gluten Free

Very good quality and quantity. Although I prefer calcium ascorbate which is easier on the stomach. Good for a everyday vitamin

Vitamin Basics & Tips

Vitamin C exists in multiple forms, with calcium ascorbate being a buffered, non-acidic variant that causes less gastrointestinal irritation compared to ascorbic acid. This makes it ideal for daily use, especially for individuals with sensitive digestion. The calcium component (10% by weight) also provides minimal supplemental mineral intake without affecting vitamin C absorption.

For optimal benefits, adults should aim for 65-90mg of daily vitamin C, not exceeding 2,000mg. Calcium ascorbate contains 10% calcium by weight, meaning a 1,000mg dose provides 100mg calcium. Pairing vitamin C with zinc enhances immune support, while combining it with iron supplements improves non-heme iron absorption by 2-3 times.

When choosing vitamin C supplements, consider both form and timing. Liposomal and mineral-bound varieties like calcium/sodium ascorbate offer better stomach tolerance. Divide doses throughout the day since the body excretes excess water-soluble vitamin C within 12 hours. Store supplements in opaque containers away from heat to prevent oxidation.

Liked product but short expiration: 600 servings expire in 6 months, check dates before buying.

Satisfied with Vitamin A quality, frustrated by limited expiration window for bulk servings. Urges expiration verification beforehand.
