Provides the natural D3 form of vitamin D (cholecalciferol)

Softgels deliver vitamin D3 in a base of organic flaxseed oil, which enhances absorption due to the fat-soluble nature of vitamin D

Available in tablets or softgels, each providing 1000 IU of vitamin D3

Available in various bottle sizes, including an economical 500-softgel size 

Natural Factors Vitamin D3 provides the natural form of vitamin D that is essential for the absorption of calcium and phosphorus. These minerals are needed for successful bone mineralization and maintenance, as well as muscle function and proper nerve transmission.

Each tablet delivers a single 25 mcg (1000 IU) dose of vitamin D3 so that sufficient levels can be maintained conveniently when dietary intake and exposure to the sun’s ultraviolet rays is low. When combined with an adequate calcium intake, each daily tablet will help prevent the brittle, weak bones of osteoporosis and support a healthy immune system. Vitamin D3 is also an important factor in reducing the risk of cognitive dysfunction.

Vitamin D3 1000 IU is available in both 90 and 180 tablet bottles and is suitable for vegetarians. It contains no artificial colours, preservatives, sweeteners, or common allergens, making it a safe product that can be recommended for the health of both mother and child during pregnancy and lactation. This product contains no GMOs and is a key factor in the maintenance of good health. 

Vitamin D3 is an essential fat-soluble vitamin made naturally in the skin from exposure to the sun’s ultraviolet rays. The sunlight converts cholesterol within the skin into a form of vitamin D3 called calciol. This is converted by the liver into calcidiol (25-hydroxyvitamin D3), which is the inactive form of vitamin D3 circulated and stored in the body. The kidneys convert calcidiol into the active form of vitamin D3 called calcitriol (1,25-dihydroxy-vitamin D3).

Vitamin D3 increases calcium absorption in the gut to sustain steady blood calcium and phosphate concentrations that enable normal bone mineralization. As a hormone, it regulates cellular production of important proteins and peptides.

Vitamin D3 helps increase the number of receptors on immune system cells to help them fight pathogenic bacteria and viruses. It helps white blood cells recognize foreign invaders and may also influence the release of protective proteins when there is an infection.

Vitamin D3 may benefit cognition by protecting neurons and supporting their development. Its receptors are found on many different tissues in the body, including those in muscles, the prostate, and the heart, indicating that vitamin D3 has more effects than we currently know.

It looks really cool and striking.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.

Stunning Gentleman's Watch
Color: Grey
This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.

Good Tissot Watch
Color: Grey
Arrived on time, in its original box, include a 2 year international warranty, into the box include a book with the Tissot brand history in Switzerland. Algo a second book with a whole catalog of Tissot watches men and women. The watch looks better when you put in on your wrist. The “naval” blue really gives the clock a classy look. The stainless steel workmanship is really good, the metal is bright and perfectly polished. The metal wristband quality is very good, did not have any problem to adjust the size , I went to my preferred clock workshop for this job, they extracted a few pieces of the band to fit to my small wrist size. Have to get used to the butterfly latch, but after a few days, now I learned to open and close it without any effort. The clock it’s very accurate, I’ve been using my Tissot for near a month and it just increased a few seconds per week. I do the setup and check accuracy with my pc clock. In short, It”s a good value watch, nice, good looking, accurate.
