过期日期与最好使用期的长度跟产品的种类和品牌有很大的关系。
易变质商品（如亚麻油或某些益生菌产品）通常有较短的有效使用日期。尽管我们的仓库是全空调气温调控，但这些易变质商品还是被冷藏存储（冷冻或冷藏库），以保持最大的新鲜度。
我们的进货部门会尽力的确认每一个商品的过期时间。不过，过期日的出入有的时候还是难免的。为了避免这类问题，我们的存货周转率在本行业甚至在各行业都是最高的。
Maintaining healthy levels of vitamin D can help mitigate cognitive decline. Plus, clinical trials confirm the importance of maintaining vitamin D levels for broad-spectrum health benefits, such as bone and immune system health. If you are already getting 1,000–3,000 IU of vitamin D in your multivitamin, Vitamin D3 5,000 IU is perfect for achieving optimal vitamin D levels.
Benefits at a Glance
Vitamin D is fat-soluble, and effects the expression of more than 200 genes in your body. It is essential for optimal health, and yet there is a widespread vitamin D deficiency. You can bring blood vitamin D to optimal levels2 through repeated sun exposure.
But sunscreens and low light in winter make that difficult, and the American Academy of Dermatology has reaffirmed that vitamin D should not be obtained from unprotected exposure to ultraviolet (UV) radiation from the sun or indoor tanning devices. Therefore, supplementing with the right amount of vitamin D goes a long way towards inhibiting vitamin D deficiency.
Vitamin D has multiple health benefits
Once vitamin D3 is produced in the skin or absorbed from food, it’s converted in the body to a metabolically active form known as calcitriol that does far more than just regulate your body’s calcium balance. Vitamin D affects cell differentiation, immunity, insulin secretion, blood pressure regulation, etc.
Perfect complement to multivitamins with vitamin D
We recommend that you supplement with 5,000 IU to 8,000 IU of vitamin D3 daily. And take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust your dosage so your optimal blood levels will be between 50–80 ng/mL year-round. So maintain optimal levels of blood vitamin D effectively and inexpensively with Life Extension vitamin D supplements!

Caution: Individuals consuming more than 2,000 IU/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 10,000 IU per day unless recommended by your doctor. Vitamin D supplementation is not recommended for individuals with high blood calcium levels. If you have a thyroid condition or are taking antithyroid medications, do not use without consulting your healthcare practitioner.
