Description

Thorne’s D-5,000 contains 5,000 IU of high-quality vitamin D3 and is NSF Certified for Sport®. Although it is well known that direct sunlight is a natural source of vitamin D, many individuals, especially the elderly, don’t get enough vitamin D from sunlight or from their diet. Be sure you get the vitamin D your body needs with Thorne’s easily absorbed Vitamin D-5,000.

Either of Thorne’s D-1,000 or D-5,000 can be an ideal way to maintain an optimal level of vitamin D in healthy individuals.*

What does NSF Certified for Sport mean on this vitamin D supplement?

NSF Certified for Sport® means the product has been independently tested and verified to contain exactly what's on the label, with no prohibited substances. This certification is trusted by professional athletes and sports organizations worldwide. For anyone subject to drug testing or simply wanting verified quality, this certification provides important peace of mind about what you're putting in your body.

Who should take Thorne Vitamin D-5,000?

This supplement is ideal for people who don't get adequate sun exposure, older adults with reduced vitamin D synthesis, athletes supporting muscle strength and performance, and anyone with low dietary vitamin D intake. The 5,000 IU dose is designed for individuals needing meaningful supplementation. Always consult your healthcare provider before starting any new supplement, especially at higher potency levels.

What are the main benefits of taking 5,000 IU of vitamin D3 daily?

Vitamin D3 at 5,000 IU supports healthy bones and teeth, promotes lean muscle mass, helps maintain muscle strength, and contributes to overall immune function. It's the same form your body naturally produces from sunlight, making it highly effective. This higher potency dose is especially beneficial for those who are deficient or have limited sun exposure throughout the year.

How should I take Thorne Vitamin D-5,000 for best results?

Take one capsule daily, preferably with a meal that contains some healthy fat, since vitamin D is fat-soluble and absorbs better alongside dietary fats. Consistency is key — daily supplementation helps maintain optimal blood levels over time. With 120 servings per bottle, one bottle provides a full four months of supply. Follow any specific guidance from your healthcare provider regarding dosage.
