00:00This common supplement may slow aging, but experts urge caution.

00:05Vitamin D, often called the sunshine vitamin, has long been recognized for its vital role in bone health.

00:12Now, emerging research suggests it might also help slow down the aging process,

00:16though too much could potentially increase disease susceptibility.

00:20A recent study at Augusta University tracked 1,031 participants with an average age of 65 over 5 years.

00:27Researchers found that vitamin D supplementation protects telomeres,

00:32the protective caps on chromosomes that naturally shorten as we age.

00:36Participants taking 2,000 IU daily preserved about 140 base pairs of telomere length compared to the placebo group.

00:44Beyond bone health, vitamin D facilitates calcium absorption and plays a significant role in immune function.

00:50Its anti-inflammatory properties may help preserve telomere length by reducing inflammation that accelerates aging.

00:56However, experts caution against high-dose supplementation without medical guidance.

01:01The study's 2,000 IU exceeds current recommendations of 600 IU for adults under 70 and 800 IU for older individuals.

01:11Some scientists warn that excessively long telomeres might paradoxically increase disease risk.

01:17Vitamin D dosage varies by individual factors such as baseline levels and sun exposure.

01:22While promising for aging, essential health practices like a balanced diet, exercise, and stress management support telomere health.

01:31Moderation and personalized care are crucial to leveraging vitamin D's benefits without risk.
