Start every day with confidence—Vitamin D3 is a vital nutrient your body naturally produces with sunlight, but many of us don’t get enough. This essential vitamin helps your body absorb calcium and phosphorus, supporting strong bones and teeth. It also plays a key role in keeping your muscles working normally and your immune system functioning as it should. Life Extension’s Vitamin D3 softgels deliver a generous 5,000 IU per serving, making it simple to top up your daily intake—especially during the darker months or if you spend more time indoors. Choose a daily routine that helps you stay on track with your wellbeing goals.
