Popularity1.2/5
1,300 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other home health monitors: bathroom scales, blood pressure monitors, pregnancy and ovulation tests, thermometers, body composition monitors, stethoscopes, glucose monitors and pulse oximeters we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
['This value-size bottle holds 250 softgels at 1,000 IU each, a lower, everyday-style potency rather than the higher-dose options common elsewhere in this roundup. At $7.19 for 250 softgels, the per-unit cost is among the lowest in this lineup.', 'The label states it is gluten-free and non-GMO with once-daily dosing. The maker markets it for immune system support, bone health, and whole-body health.', 'Review volume here is lighter than on some other Life Extension products in this set, with 1,300 ratings, but the 4.8 average and roughly 1,000 monthly buyers still point to consistent satisfaction.']

Frequently asked questions
Is 1,000 IU enough for daily use?
It is a common everyday maintenance dose used in many general-purpose D3 products, lower than the 5,000 IU or higher options in this roundup. A healthcare professional can advise on what potency fits your needs.
How long will a 250-count bottle last?
At one softgel a day, it is built to last well over eight months.
What does the maker claim it supports?
The label markets it for immune system support, bone health, and general whole-body health. These are the maker's stated claims, not medical guarantees.
