What’s inside this formula?
Thorne’s Vitamin D-1,000 is listed here in the vitamin d collection. This article looks at the selected 90 capsules — US label pack, then puts its ingredients into context.
Vitamin D helps the body absorb calcium and is needed for normal muscle and nerve function. Supplementation can correct inadequate intake or deficiency in an appropriate care plan. The reason for using it matters more than choosing the largest number on the front of a bottle.
The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.
The complete declared ingredient amounts
The current table uses a serving of 1 capsule. It declares Vitamin D3 25 mcg. These are manufacturer label amounts, not a personal dosing instruction.
The comparison detail that changes the decision
The 25 mcg vitamin D3 amount equals 1,000 IU. This capsule has no vitamin K declared in its active-ingredient table. The selected product has 90 labelled servings per container. Matching ingredient form and serving matters more than bottle count.
Excipients, cautions and evidence limits
Other listed ingredients: Leucine, Microcrystalline Cellulose, Silicon Dioxide, Hypromellose (derived from cellulose) capsule, Vitamin E (d-Alpha-Tocopherol). Add vitamin D from all supplements before choosing a product. Hypercalcaemia, kidney conditions and prescribed vitamin D treatment warrant clinician review. No independent batch test or exact-formula clinical outcome was verified in this review. Current Indian stock and delivered price remain unverified.
Where might it be useful?
Calcium absorption
Adequate vitamin D helps the body use calcium to maintain bones.
Normal muscle function
Vitamin D is needed for muscle movement; correcting deficiency is different from boosting performance in someone already sufficient.
What the research can — and cannot — tell us
Vitamin D has a well-established role in preventing deficiency disorders. Wider claims about weight loss, mood or routine disease prevention are not established for every user. D3 and D2 products, combination formulas and high-strength products should be compared using the actual vitamin amount.
What deserves your attention?
Add vitamin D from all supplements before choosing a product. Hypercalcaemia, kidney conditions and prescribed vitamin D treatment warrant clinician review.
Suitability comes before strength
Excessive supplemental vitamin D can cause serious harm, including high calcium and kidney problems. Review high-strength use and total combined intake with a qualified clinician.
Dietary details for this product
Dietary status not confirmed The reviewed current label does not explicitly establish vegan or vegetarian status for the complete formula. A cellulose capsule or dairy-free statement alone is not a whole-formula declaration.
A dietary label and an allergy assessment answer different questions. Check every ingredient, the capsule or softgel materials and the allergen statement on the pack you receive. If you take medicines, have a health condition, are pregnant or are choosing for a child, discuss the full formula with a qualified clinician.
