Check the original label ↗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.
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?
The gelatin softgel is animal-derived. Confirm both the 25 mcg strength and 90-count pack; other Life Extension vitamin D products have different strengths, counts or added ingredients.
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.
