Advanced Immunity Spectrum

I t meets my customers needs

Worth the value! Only two drops a dose versus .5 or 1ML, which means the bottle will last so much longer. And completely, 100% tasteless. Not that oily texture like others I’ve tried either! This will be my go-to from here on out!

My vitamin d levels are great using this stuff.

Just got my blood test after taking this for a while. My vitamin D level is very good now.

I use this everyday in my coffee and is a great supplement!

On my previous visit my Dr told me my vitamin D levels were low. I started taking this about 6 months ago and just had my follow up appt. Vitamin D levels were perfect. Couldn’t be any easier-just a few tasteless drops under the tongue and your good to go.

Did not do labs before to be able to speak to quality.

Great product easy to use. Several drops in my morning coffee each day.

Very easy to use, I add the drops to my son’s juice.

My 19 yr old son is vit D deficient and experiences insomnia, depression, panic attacks, and hair loss. He took D & K2 gummies for 4 months and they helped some, but due to sensory issues, the flavor and texture wasn't palatable. I bought the drops and he doesn't mind it. Has zero flavor and an easy to use dropper.Update: Son's mood greatly improved on day 3. Soon after taking, he's tired and sleeps soundly. I believe these drops are more effective than the gummies.Update Oct 30: Early Sept, son said the oil made his throat feel strange so I decided to add it in his food and continued this until the end of Sept. then stopped all together. A month has passed without taking it. He had his vit D level checked this week and results showed a huge increase from 19 to 70, putting him the normal range! Hair loss stabilized, panic attack is now periodic anxiety, sleeps many hours.1/13/24 Another update! I'm age 55-never had my D level tested until last week and the result was a big surprse: 16.9 so my doctor said to take 2000IU D3 daily which is 4 droppers of the liquid. My blood pressure is very low 90/60 so I'm going to start with half the dose for now. Will update when my D level is checked again.

This D3/K2 works. I've had a Vitamin D deficiency for 20+ years. I would get a prescription for Vitamin D pills from my doctor and as soon as I stopped taking them, my Vitamin D would go down again. I tried Ultra6 D3/K2 because I read that D3 should be taken together K2. It is so easy to take and it doesn't have a taste and it has a very light oil consistency. In October my Labs showed my D was down again. I took ultra6 and I just had my lab results come back today. My D levels are healthy! This works. I recommend Ultra6 Vitaminn D3/K2 to anyone that has a deficiency.

Quality vitamin D supplements are a necessity living in Alaska's interior. Even those of you with office jobs who don't see the sun much regardless where you live, may need to check out your D levels. Chronically low D seems to be an epidemic anymore. I had no idea how greatly a simple single vitamin effects so much of your health. I was tired all the time, my body was achy, I was depressed, my skin and hair looked terrible. I truly didn't know what was wrong (I am originally from Texas and outdoorsy so I got the D I needed). I also didn't know that a good diet still doesn't give the D you need, and living in northern latitudes sun exposure isn't strong enough. When I finally did the research it was clear that I was suffering from D deficiency, in just a year of living up here.I have seen HUGE improvements having taken this every day for about 5 months. It's tasteless and seems to be lasting forever. My kids take it without complaint. The liquid is absorbed easier than pill form. Seriously...get your D checked out, it's kinda a big deal. (Please tell me I'm not the only one who sees irony in that everyone needs some big D in their lives hahaha)

I have a gluten sensitivity, so when I eat anything that contains wheat, it impairs my body's ability to absorb nutrients. I was getting headaches, possibly from vitamin D deficiency since I have been deficient many times before.. at first I took another brand of vitamin D but, but I only had one pill of that. Immediately my headache went away. The next morning my headache was back, so I used this brand since I had it in my refrigerator. I took six drops or so of it and my headache went away again..I'll just continue to take a few drops of this every time a headache comes back. It seems to be working. I wouldn't say that this particular brand is superior to other brands, but I don't think there's anything wrong with it. I personally prefer the vitamin D's that are in olive oil since my doctor told me that I need to be taking more olive oil, but these drops are fine too..

This raised my vitamin D level, without side effects. My level has been low for quite some time. When I tried other supplements, they gave me panic attacks. Last summer I tried raising my vitamin D level via the sun (and I was making a point to get a lot of it), but that only brought my level from 19 to 24. In October, I started taking these drops, along with a magnesium supplement since I read that may be a reason why supplementation was raising my anxiety levels. I have averaged about 3 drops a day over the last 9 months and last week my levels were measured at 37 ng/ml. I probably could have raised it faster, but I didn't want to have adverse reactions.

This is an excellent product! I know that many people say they need more research to see if D3 can help lower blood pressure, but I can say this: I had a high blood pressure problem that my D3 gel pills didn't do much to help. But since taking this D3 sublingually, my BP has worked itself back to normal, and that's the only thing I did different. The taste is fine, the price is right, the packaging is careful, and the seller is supportive. I will always go to this seller because excellent products need the support of excellent service. I'm being completely honest and have not received any form of incentive for this product or my review. I just think they deserve an excellent review/rating, and consumers deserve to know!
