Amazing Vitamin D drops

I have always been low on Vitamin D but not big on swallowing pills. While searching for the right product I found this product which happened to be organic and liquid. While I wasn't sure how the taste would be it was absolutely fine. This is def a Vitamin I can get use to. Please send coupons my way.

Dosage is a little weird - tastes like coconut oil

Overall I like this vitamin D. It’s kind of an oily consistency but not very oily. The flavor is kind of like a light flavored coconut oil. At least that’s what it tastes like to me.The dosage is a little odd to me because it says 20 drops for one ML and I looked in the mirror while I did it and 20 drops is only half of the dropperfull. The dropper is not marked at all but the bottle says that one whole dropperfull is one ML. So that would mean 40 drops would be the dosage. So I’m a little confused if I should use the entire dropper full for one ML or if I should use 20 drops which really only comes to half of the dropper. That is why it lost the star.It is clearly marked vegan although the directions and measurements are printed super tiny - but most bottles supplements do the same thing…

Good value, but not as convenient to use as other brands

Having taken vitamin D3 capsules for years, I decided to try D3 drops. I ordered several different brands (both with and without vitamin K2) to compare. Without laboratory analysis, it’s impossible for a consumer to know if one vitamin D3 oil is more effective than another, so I can comment only on the perceived quality and convenience of the product.All the drops tasted pretty much the same — oily and not great-tasting, but far from horrible. You could mix it in a drink, but it’s easier just to put it on or under your tongue. Also, all the drops claimed the same potency per drop, so it’s easy to compare apples to apples price-wise.THE GOOD: The Triquetra D3 drops are reasonably priced ($15.99 at time of order.)THE BAD:- I found the protective plastic wrapper impossible to remove easily; if it has a perforated tear strip, I couldn’t find it. I ended up up unscrewing and removing the entire top (which can be removed with the “security seal” completely intact), and then snipping the edge of the plastic strip with a scissors so I could remove it. Opening the bottle shouldn’t be that difficult.- The bulb on the eye dropper feels a little thin to me. It will probably last long enough to use all the product, but seems a little on the cheap side.- The top is not childproof (which may or may not matter to you).- The dropper has no measurement markings at all. You have to count drops, which is annoying and, I think, less accurate than having a printed scale on the dropper.- The recommended dosage (10,000 IU) seems to be outrageously high. Based on my research, reputable medical websites recommend far lower doses for most people. Of course, since it’s a liquid, it’s easy enough to do a little math and take whatever dose you want, but again, since there is no scale on the dropper, you’ll be busy counting drops while trying to release just one drop at a time.- The instructions claim that one full dropper is 1.0 ml, but compared to other medicine droppers I have which are labeled with a scale, one full dropper appears to be *more* than 1.0 ml (see photo), so be sure to count those drops carefully to get the dosage you want. (Seriously, would it have been so difficult for the manufacturer to add a readable scale to the eye dropper?! Talk about cutting corners…)- Since it doesn’t contain vitamin K2, I will need to take a K2 supplement separately. (Note re vitamin K2: From everything I’ve read, it is important to take Vitamin K2 with D3; they work synergistically to ensure that calcium is absorbed by your bones, not left clogging up your arteries. There seems to be much debate over whether there should be a specific ratio between the levels of D3 and K2, or whether the dosages of each are independent of one another. Read 5 websites and you’ll get 6 opinions on what the “best” ratio is. After much Googling, I decided to leave that fight to the nutrition scientists and go on faith that the relative dosage of each is appropriate in products which contain both.)For the price, I think the product is fine is you just want vitamin D3 and don’t mind carefully counting each drop.4 stars.

GREAT FOR FAST DELIVERY OF VITAMIN D

I love that this vitamin d is vegan and USDA organic. It is made with algae and MCT oil. It is packaged and labeled well with listed ingredients. The oil is light with a mild flavor that absorbs easily in the mouth. Priced well, easy to take, absorbs easily. A+

Easily Customized Daily Dosage Levels

I like the fact that your individually suited dosage rate is so easily adjusted by number of drops dispensed. Sublingual administration (drops placed under your tongue), or option to dilute in liquid that you drink adds even more flexibility. I’m trying to address my fatty liver condition, and I find the statement that through sublingual administration, this product bypasses the liver to be very encouraging.I’ll take 2 drops a day under my tongue to more than adequately cover the daily recommended value for Vitamin D3. At this rate, this bottle covers 300 days, and in my opinion, makes this item a tremendous value.U.S. Quarter Dollar shown in my photo for sizing comparison.Thanks for indicating if you’ve found my comments and photo helpful in your consideration of this product.

Wish they could get this straight.

From a quality and effectiveness standpoint, Triquetra is top shelf. Why the single star? To get attention. I have been a regular user of the D3+K2 liquid, which is fantastic. A dropper full under the tongue and the effects are immediate. I ran out and went to order it. Triquetra said it was out of stock and if I entered my email they would let me know when I could order again.

I received an email a few days later that it was available again. Clicked on it, ordered it. It wasn’t until it showed up that I realized that they had pulled the “Bait and Switch” on me—just the D3, no K2. Very, very unhappy about this.

easy to use and adjust dosage

Because of the dropper, it is easy to measure out the precise amount desired. Being liquid and sublingual, it is more effective than capsules. The taste is fairly neutral. The customer service is exceptional (they replaced a bottle that was cloudy and had a very different taste).

Life changing- seriously!

After being diagnosed with subclinical hypothyroidism and some subsequent fertility issues, it was found that my vitamin D was very, very low. I started taking 5000-8000 iu daily and within 4 weeks, my vitamin d levels were up to a normal level and my TSH was down to a more normal range. My symptoms lessened and I had more energy. My husband calls it my liquid sunshine.
Also- I am a very fair skinned person so normally I burn in the sun but ever since I started taking vitamin d tinctures, I haven’t gotten burned once and have even gotten a nice tan! Not sure if that’s related but thought it was pretty neat.
