Doctor's Best Vitamin D3 2500IU with Vitashine D3, Non-GMO, Vegan, Gluten Free, Soy Free, Regulates Immune Function, Supports Healthy Bones, 60 Count

My vitamin D level was very low. I live in the Northeast and winter doesn't allow me to get much sunshine. After taking this, my levels have returned to normal, so I know that this is effective. I am vegan so the ingredients are important to me. The dosage that works for me is one in the AM and 1 in the PM always with food. I have had no side effects, there is no icky taste and it is easy to use. I use the subscribe and save feature so that I don't run out.

I'm glad that this is vegan. I take one in the morning and one at lunch because I'm low in vitamin D.

Good product. We havee been taking these Vitamin D tablets daily for three weeks, and I’ve noticed a real boost in my overall energy and mood—especially on gloomy days. The capsules are easy to swallow, and the secure, resealable bottle ensures they stay fresh. Great value for the price, and I feel confident knowing I’m supporting my bone and immune health!

It is difficult to find a D3 product not sourced from lanolin to which I am allergic. There are very few products that do not use lanolin and they are generally prohibitively expensive. This product is the lowest cost that I've found and I've been happy with it. I have had a small decrease in my D3 blood level since using but I am still well in the acceptable range. I'm sticking with it.

I am vitamin D deficient which most people over 50 are. I believe in Dr. Berg’s knowledge and recommendations on supplements. I have not had bloodwork again since I have started taking these.
