Thone makes good quality products in my opinion this one included. This D/K2 supplement has the ingredient K2-MK4 menaquinon, which requires more often dosing compared to the preferred K2-MK7. The liquid form makes it easy to split does at meals or with a snack throughout the day. Taste is neutral. The package top is like an essential oil bottle at works great with a little practice and patience. I take a dosage 2000-10000 IU of D a day depending on sun time, health, and mood. The bottle has qty 600 of 1000 IU servings. I haven't had my D levels tested to know if this supplement has improved them. The recommended levels are for minimum body functioning. Most people in modern society could use more.

First of all: Get your vitamin D from the sun Second: Okay, so you live in England like me. I combine this during winter with a Sperti lamp. After all, Vitamin D is only a marker of UV exposure, there is so much more going on that just Vitamin D when you get some skin in the game. I use this in various dosages a couple of times a week but only because my blood levels are always complete trash. The pretty: Glass bottle (no plastic to give me nightmares and doom-spirals) and is compact in the fridge. The bad: More expensive than the NOW Vitamin D drops and half the strength. Also, the NOW product does not use tocopherols. For some of us, tocopherols genetically cause neuroinflammation and have to use tocotrienols instead (this is due to the AA genotype for rs1695 - if ...

Both vitamin D and vitamin K2 support bone and muscle health, along with cardiovascular health and immune function. It is important to maintain an optimal level of vitamin D in the body through all stages of life, from fetal development to old age. Vitamin K2, a series of molecules known as menaquinones, exerts a more powerful influence on bone than does vitamin K1. The vitamin K2 in this formula is the well-studied MK-4. Combining vitamins D and K can provide greater support of the immune and cardiovascular systems than each offers separately. For example, vitamin D is necessary for calcium absorption, and vitamin K is important for directing calcium to the bones and away from the soft tissues, such as blood vessels and kidneys.

Thorne's Vitamin D/ K2 Liquid also provides nutritional support for oncology patients.One study in postmenopausal women found a combination of minerals along with vitamins D and K maintained healthy artery elasticity, compared to two other groups of women who received either minerals with vitamin D but not vitamin K, or placebo. Thorne's Vitamin D/K2 Liquid is in medium chain triglyceride oil, preserved with mixed tocopherols.
I rotate this with MegaQuinone by Microbiome Labs (it would be cool if iHerb would stock that product!) to ensure I get the full spectrum of Vitamin K. My diet is limited currently which bothers me and necessitates the need for supplements. Obviously, you should focus on getting your nutrition needs from food, but if you struggle like myself, then this is a decent product. My gripes are: 1. the price. 2. the use of tocopherols. For some of us, tocopherols genetically cause neuroinflammation and have to use tocotrienols instead (this is due to the AA genotype for rs1695, if you are interested and want to check for yourself).

Tocopherol/regular Vitamin E supplements themselves give me terrible brain fog and behavioural issues. The pros: It comes in glass, you can make a bottle last much longer if you half the dosage to 7 or 8 drops - you'll be getting a 6500% of your RDA.
The liquid form makes it easy to add Vitamin D to smoothies, yogurt, or any other food or drink. No more struggling to swallow large pills!Each serving provides the recommended daily amount of vitamin D, ensuring optimal health benefits.This high-quality supplement is surprisingly affordable, making it a great value for the whole family.Getting enough vitamin D can be a challenge, especially during the winter months. Vitamin D Liquid has been a lifesaver for our family. This convenient and effective supplement makes it easy to ensure everyone is getting the vitamin D they need.
Great quality vitamin D, natural and not synthetic as is sold in a regular drugstore. Effective for immune system support in flue season. Contains only natural ingredients. Good size, enough for a long time, even for a few years because you don't need to take it on a daily basis, only when feeling unwell. The dosage is indicated on a bottle. The bottle itself is glass, not plastic. You may take it on a daily basis (2 drops) or once a week 2x7. Good when you live in a country with sun deficiency. Has no taste, so easy to give to children. The package is really enough for a very long time. Take it together with vit C + Zinc for better effect when you caught cold.
Have been taking these drops for over four months and more than anything I have noticed a remarkable difference in my energy levels which have been directly impacting my mentality/self-esteem. I have been feeling a lot more replenished, less likely to procrastinate or make excuses, and far more likely to engage in a sociable and proactive lifestyle. I find myself putting in far more effort with work and enjoying doing so. It has become much easier to enter flow state. I see now why some people say depressive symptoms may be linked to vitamin D deficiency. I have since then bought multiple bottles for my entire family.Bottle also lasts a long time and is so worth the price point. Love this stuff, please never change the formula or quality of your products!
You know all those articles that state scientific, double blind studies have not proven the efficacy of vitamin supplements? Well, I'm only a study of one but WOW, this thing actually works. It's only been three weeks but for the first time since hitting menopause, my nails are growing again and no longer feel brittle. They are starting to feel strong like they used to. If this is the visible impact of this vitamin, I can only imagine how much stronger my bones are getting inside my body.A little about me - I get NO vitamin D whatsoever from my diet (no dairy, eat little meat, no fortified food), hate the sun and as mentioned hit menopause 1 to 2 years back and I can't believe how much my health has been impacted. I knew I needed some source of Vitamin D so ... MoreYou know all those articles that state scientific, double blind studies have not proven the efficacy of vitamin supplements?

I knew I needed some source of Vitamin D so ordered this one.I researched (probably too much) info about Vitamin D supplements and this one came highly recommended.Adequate dose of Vitamin D, had the all imp't K2 to provide that synergistic effect and was at a very reasonable price point (why are boutique vitamins and high end lotions getting so expensive nowadays?). Thorne's vitamin may be downright inexpensive as I think there may be 1000 drops in this one little bottle.As for the dispenser, I LOVE it for its accuracy and want to thank the other reviewers for letting me know how to use (so I'll share the same). There is no reason to shake the bottle to dispense the liquid - simply turn the bottle complete upside down, a very precise drop of the vitamin will slowly make its way down the opening followed by another drop. It's also at a slow enough pace that you have lots of control and can easily turn it over without any contents spilling over the edge. This is imp't as a daily dose is just 2 little flavorless drops.Another tip from another reviewer, because a day's supply is the aforementioned 2 little drops, I dispense the two drops onto something - an orange, a blueberry, really it could be anything (your chicken mcnuggets).Really, really pleased w/the effect of this vitamin - which at least for my nails - 100% works and wow, works FAST. Also impressed w/IHerb as well - product was well priced, they had a nice little promotion and it was shipped relatively quickly. I may need to sign up for auto ship for myself and my family for this product. I promise, I am in no way affiliated w/this company- just a person delighted with a product that actually works (love the liquid vitamins - I do not like large pills and these flavorless liquids makes it painless).
