Life Extension Vitamin D3 with Sea-Iodine™, 125 mcg (5000 IU) – Immune Support, Bone Health, Thyroid Health – 1 Daily, Gluten-Free, Non-GMO – 60 Capsules

I am a Life-Extension customer because I believe in their products and research behind them. I've been using this product for quite a few years now and my Vitamin D level is great! This is a quality product. I purchase from Amazon on occasion because it is very easy if I want tot ship vitamins to family members at different locations. I highly recommend. Best of health to us all during this pandemic!

Good product.

Taking it for years and it’s great for my body

First time trying this brand, but with thyroid issues, I was thrilled to find a D3 option with iodine! Very easy to swallow, flavorless and a great price point! Efficacy equally pleasing.

Just what the Dr. Ordered

I take this and their Iron with protein (I believe that is what it’s called) and my hair has stopped falling out after having a certain virus! It’s very effective. Side note: I eat sea salt almost strictly and don’t get enough iodine. The D was the bonus part for me, but also needed. This is definitely one of my go-to trusted brands!

Good product

This is the only brand I use because I trust life extension. This D3 has the amount of units that I want to use and the sea iodine to make it more absorbable.
