Sports Research - 純素 D3 5000iu + 維生素 K2 -100 微克，60 粒素食軟膠囊

Why did you pick this product vs others?:It's a great product and I can tell It's working.

It's the best vitamin D3 I've ever taken, and I say this with good reason, since I've never managed to get my vitamin D level to 60 nmol/L, which is what I currently measure and maintain.Something very important to note is that we always have to check (read the description) what other ingredients are included in the formula, and here EVERYTHING is healthy and without surprises.Finally, if we don't activate it with sunlight, it's useless.

Been taking them for years. The formula changed at some point, but it does what it's supposed to.

The vitamins come in an attractive container and are the quality I expected. I cannot say they have made a difference, as you need to take them more than a couple weeks. But, I expect them to work and improve my immune system and more.

After listening to many Joe Rogan podcasts with health experts, they convinced me to use it and I have for many months now.  I am going to keep using it.
