Very informative. Thanks for sharing. Report
Good article. Report
I am on Warfarin blood thinner for 3 clots in one lung, I eat a average of 3 times the amount of vitamin K needed. If I ate less I would not be healthy. My I.N.R. is 2.2. I want to get it to 2.5-3.5 the healthy number for people on blood thinners. I get tested 2 times per. week. I track vitamin K on self It lists vitamin K and Potassium separately, vitamin K 1 is Potassium, vitamin k is also referred to vitamin k 2. They are not the same and Spark tracks them together, that is why it is not correct for people that need to know the amount. You can look up a list of foods with any vitamin you want, it has a complete list of all 20 proteins, all 9 omegas and you can look up foods by the % of carbs, fat and protein you want combined, to get the exact amount at every meal. I will be on a precise diet for the rest of my life, also intolerant to gluten, eggs, most dairy and high acid foods and have minor kidney disease. My diet is complicated now. Report
I know I'm not getting half the vitamins I need by nutrition so I do an oral vitamin. Report
Funny how people differ. My mom has too much vitamin K. I have to bring her to Quest every couple of weeks to have her blood checked out. Her blood is thick with the stuff so we have to keep tabs on it. Report
I was looking for vitamin K- not in the article, but it comes up at the second "resource" on Spark search for vitamin K. I haven't found anything yet on spark about vitamin K. Report
Just as one example of a recent well-documented medical report on vitamin D, check out
11. This report established no negative side effects for 40,000 IU daily (an amount much higher than I would take). The article argues for new recommendations for vitamin D recommendations. Many doctors are arguing for 8000 IU daily as the recommended dose but this article gives good evidence that 14,000 IU may be better to reach the appropriate serum 25 D levels for 97.5% of the US population. It remains to be seen how long it will take for this kind of information to become more commonly known among the general M.D. population who don't have nearly enough time to read and keep up on research.

This article was a bit of disappointment to me because it uses old and outdated information on dosages. For instance, there has NEVER been a documented case of vitamin D overdose. Women taking 60,000 IU daily intravenously for breast cancer treatments have experienced some nausea. (Vitamin D causes apoptosis -- the death of cancer cells.) Moreover, the article makes no mention of the fact that Vitamin D is not a vitamin but actually is a hormone. Medical doctors at have documented no side effects at 10,000 IU / day. They currently recommend at least 8,000 IU / day for adults.

With regard to vitamin C, many doctors recommend a dose of 3000 mg / day during flu season as an effective prophylactic. 1000 mg / day is a common dose with little danger of side effects. Because vitamin C is water soluble, your body excretes what it does not use. Those who take vitamin C regularly need to be aware that their body can "adjust" to the dosage. This can result in temporary adverse effects when they quit taking it (such as bleeding gums, easier bruising, etc.). (Vitamin C improves capillary integrity.) The best vitamin C comes with 10% of the dosage in citrus bioflavonoids. One word of caution to pregnant women: citrus bioflavonoids toughen the structure of the amniotic sack which can make it more difficult for your water to break during labor.

The article is right to warn of the danger of Vitamin A megadoses and the cautions about vitamin B for pregnant and nursing women. I do, however, wish it would break down the B vitamins a bit more. For instance, folic acid (no more than 800 mcg / day) helps to reduce inflammation in the body.

Many of the potential dangers of water-solube vitamins are mitigated by simply drinking plenty of water. Fat-soluble vitamins (such as A) need more caution regarding their use.

I understand that articles like this are written to old published standards mainly out of a sense of legal caution. But it behooves all of us to study current medical (e.g. coming from a group of people with M.D. degrees and not the latest Internet self-proclaimed guru) literature to get up-to-date information on nutrition. Sadly, however, the medical industry as a whole is more focused on allopathy -- giving medications to offset your current symptoms -- than it is on treating the root cause of many diseases which are often associated with nutritional deficiencies.

It took me several attempts to find a medical doctor as my personal physician that actually kept up with research on vitamins and nutrition. There are few of these professionals, but they are out there. Report
Helpful article. Would like a more comprehensive article that includes more vitamins, but I guess SP needs to keep them at a certain length, or people might not read the whole thing. Report
