How it works

  • Very few foods naturally contain vitamin D, and most all D3 supplements are sourced from lanolin — the fat of lamb’s wool. 
  • These liquid drops are made from non-GMO, vegan lichen.
  • Vitamin D3, or cholecalciferol, aids the body in absorbing phosphorus and calcium, supporting immune functions and bone health. 
  • For those who are interested in megadosing vitamin D, this product contains 100 mcg (4000 IU) vitamin D per serving.

This tastes so good!

I am obsessed with the flavor of this vitamin D!

Vitamin D3 Mega dose 5 stars!

I had some lab work done and I was deficient on vitamin D3. I knew Mary Ruth's provided organic supplements and knew this is where I needed to get mine. Since taking the supplement my lab works are back in good standing and I'm feeling so much more energetic. I also take this with the magnesium calm and have been feeling so good. This is my go to brand and D3 recommendation to everyone! Taste good as well.

Love it!

This is a great way to get the extra vitamin d3 that my doctor says I need to take. The taste is not bad, interesting that has a pineapple flavor. The only reason I can’t give 5 stars is that the dropper is unmarked which forces me to guess as to the dose that I am actually consuming. Please fix this! People should not be taking supplements without knowing exactly what they are taking.

LOVE Mary Ruth's products

As a doula, I am always suggesting Mary Ruth's products. This Vitamin D drop was fantastic for myself though. The taste was subtle, and not overpowering. I usually take Vitamin D in the winter when I'm seeing a lot less sunshine, so super grateful for this.

Have A Question? Great, Ask Us!

Really. We are here to answer any question you may have.

Why take a megadose of D3?

Megadosing is a term to describe taking doses well over the regular daily recommended dosage of a vitamin. Limited studies have shown benefits to megadosing with specific vitamins and minerals but we always recommend that everyone check with their physician or healthcare professional before beginning any new wellness supplement to make sure the supplement is suitable for their health.

Where is the D3 sourced from?

Our D3 is sourced from wild-crafted, non-GMO, vegan lichen!

Why should I take the D3 drops over the D3 gummies or the D3 spray?

It would depend on your specific needs. The D3 gummies offer 1000 IU per gummy, while the D3 spray provides 800 IU per serving. If you are looking to supplement because of a deficiency, these megadose drops may be better for you, as they contain 100 mcg (4000 IU) which is over the recommended daily dosage. As with any supplement, it’s best to ask your physician or healthcare professional what would be best for you. Your physician, or healthcare professional knows you best, knows what other supplements or prescriptions you are already on, as well as knowing if you are facing any health challenges.
