The note at the bottom of this Guardian article ‘the science behind dietary supplements’ states that the website mentioned in the article is “an independent encyclopedia on supplementation and nutrition. It does not accept advertising.” However, nowhere in the article does it mention any other website that the author is involved with. Well, I found one that looked pretty interesting.
Spencer Nadolsky is listed on LinkedIn as owner / physician at Leaner Living – https://www.linkedin.com/pub/spencer-nadolsky-do/9/b01/784 (Karl Nadolsky is down as being a co-founder of Leaner Living on his LinkedIn profile, and his name and face are at the top of pages on the site). Leaner Living has a supplement store. You can buy vitamin K & vitamin D pills from the site. Is this relevant to the Guardian article authored by Spencer Nadolsky? Well…
Instead of taking one pill that can’t possibly fit every person’s daily requirements, we recommend supplementing specific deficiencies or needs. If you’re worried about a particular health problem, search for the common vitamin weakness, and look at your diet. Common deficiencies include vitamins D, K, and minerals such as magnesium. For instance, if you don’t eat many vegetables, there’s a high likelihood you could use some more vitamin K.
For those with genuine deficiency, vitamin D supplementation has truly beneficial effects. If your vitamin D levels are in check, you won’t notice much difference. A blood test will show your vitamin D levels, and from there you can make an informed decision. If you are not due for a checkup any time soon, take 2,000 IU per day. This has been shown to be both a safe and effective dose.
So, yes, I think it might be relevant.
Instead of recommending that people who don’t eat many vegetables try eating more, the author says “you could use some more vitamin K”. And vitamin D at 2000iu (the same dosage as in the pills sold at the link above) is recommended before having a blood test to see if levels are low. Pills now, test to see if you need them later…
Oh dear. I think I might drop the Guardian an email.
