Sublimely amazing

I’ve be using the Bone Broth, “Redwood,” the Vitamin D and the prebiotic and probiotics with amazing results. I highly recommend UMZU to anyone seeking greater wellness in their lives.

Feeling great / Ease of use

This is an easy to use supplement. My mood is top notch. I add my drops to all of my juices, smoothies, and even my Total Sleep. Recommend to all, especially those used to sunless winters and seasonal depression. Recommend by this Canadian.

Messy Dropper

Been taking it with breakfast & feeling energetic all morning. The light oil tends to leak out of the dropper, making the cap & bottle slippery. Don't know if topical application (my oily hand) is of any use. Please advise.

Love this product

This is great, no bad after taste and if you need a boost of your Vitamin D3 there is not better way than UMZU Liquid. I can tell that my mood is better, I actually think I am sharper now after taking this product compared to the over the counter D3 you buy in the store. I love UMZU Products and will continue to order when needed

Great Product. Good Company!

I love the pure ease of taking D3 in this form.. no capsules to swallow. I can also add this into a drink if need be.. I actually add this to my cat's food. So we are ALL gaining from the benefits. Cheaper to build the immune than recover it, both in people and animals.

Skeptical at first but I knew I had circulation issues. I’ve never really been very veiny or vascular. Just finished my first bottle, started seeing result around end of week 1. Love it. Veins popping in my arms now.

D3 works for me

I haven’t been sick since I started taking it. It’s easy to take and taste isn’t bad at all. I feel more active and seem to get out of bed easier than before I started taking it. I’m pleased so far.

Definitely a difference!!

It’s been over 2 months since I’ve been regularly taking D3; I have totally felt a difference in my mood has been stressful and since taking this I feel less wound up and not in control. I don’t get as frustrated with the things that are inherently out of my control, and have the level headedness to tackle the things that are in my control that I need to tackle. Over all I’ve felt a big difference in my frustration/stress levels...been stacking with Mucana and that’s been great! Totally love all Umzu products I’ve tried so far...have plans to expanding my daily supps once I start getting paid from new job!

Liquid Sunshine!

This is the easiest way to get this crucial nutrient! I’ve always been D3 deficient, even when I take a supplement in pill form, but after using this daily for two months my levels are normal. Highly recommend!
