This review is from Amazon.com for product:

DEVA Vegan Vitamin D2 800 IU, Ergocalciferol Supplement with No Animal Ingredients, 90 Tablets, 1-Pack

I have had issues with some store bought vitamin D making me nauseous. This one does not do that! I am still waiting to see the test results again in a couple of months.

Vitamin Basics & Tips

Vitamin D plays a crucial role in calcium absorption, immune function, and bone health. Unlike water-soluble vitamins, it's fat-soluble and can be stored in body tissues, which explains why some people experience nausea with poorly formulated supplements - excess unabsorbed vitamin D may irritate the digestive system. The nausea-free experience described in the review suggests this product likely uses superior absorption methods like micellization or combines vitamin D with healthy fats to enhance bioavailability.

Regular blood tests (25-hydroxyvitamin D test) are recommended when supplementing, as optimal levels fall between 30-50 ng/mL. Deficiency symptoms include fatigue, bone pain, and frequent infections, while excessive intake can cause toxicity. Most adults need 600-800 IU daily, though some require prescription-strength doses. Natural sources include sunlight exposure (10-30 minutes midday), fatty fish, and fortified foods.

When choosing supplements, consider third-party tested products with complementary nutrients like vitamin K2 for proper calcium distribution. Those with digestive sensitivities should opt for emulsified forms or take supplements with meals containing healthy fats to improve tolerance and absorption.
