The information in that article is accurate except, Vit. D3 enhances absorption of Calcium into the bones.Without D3, the Calcium ends up in your arteries and causes hardening of the arteries and puts you in danger of a heart attack. Also, Boron is needed for Calcium absorption. Then there is the issue of what type of Calcium (the source) is needed to accomplish whatever it is you want to accomplish. Par Ex: MCHC (mycrocrystalline hydroxyappetite) from the shin bones of veal calves, is needed to prevent and reverse osteoporosis. There's no one size fits all situations. So, once again, a blood test is needed to determine what and how much, if anything, you need. Food based vitamins are better than synthetics. They are more expensive but cheaper than being ill.sateeb wrote: ↑Fri Aug 28, 2020 3:49 pm https://www.mdlinx.com/article/dangerou ... CZjX1sjB2K
Not sure about the veracity of the site but it claims to be scientific.
A decent read.

SUPPLEMENTS & VITAMINS
Dangerous duos: 5 supplement combos to avoid
Melissa Sammy|June 11, 2020
overall, most Americans are getting enough of some important nutrients—like folate, vitamin D, and iodine—according to the CDC. The bad news? Many of us aren’t getting enough of all the major vitamins and minerals our bodies need. For instance, according to the most recent US Dietary Guidelines, a number of Americans aren’t getting sufficient amounts of dietary fiber, potassium, choline, magnesium, calcium, iron, and vitamins, A, D, E, and C. So, what do we do when we have one or more nutritional deficiencies? We either tweak our food choices or take supplements to fill these gaps. In fact, 86% of Americans take vitamins or supplements, according to a poll conducted on behalf of the American Osteopathic Association. But, if you have more than one nutritional deficiency—or are already taking supplements to support another key area of health—can you save yourself some time by taking your meds all at once?
You can—but it’s probably not a good idea. For some supplements, optimal absorption can depend on the time of day taken. Not only that—taking certain vitamins, minerals, or other supplements together can also reduce absorption and may result in adverse interactions, which can be harmful to your health. Let’s take a look at five supplement combos you should avoid.
Multivitamins
But, before we get to that, we need to address the elephant in the room: multivitamins. If certain nutrients can adversely interact with one another, then how or why are multivitamins even on the market? The answer isn’t so cut and dried. Most multivitamins are formulated in such a way to counteract any potential negative nutrient-nutrient interactions. They contain the appropriate levels of both synergistic and antagonistic nutrients, meaning that some vitamins and minerals can enhance or inhibit others.
For example, researchers have shown that magnesium can improve vitamin D levels. On the other hand, vitamin A can decrease vitamin D uptake. That’s why you’ll almost always find that the percentage daily value (% DV) of vitamin D is higher than vitamin A on most multivitamin nutrition labels.
The downside to this is that you could be getting too much or too little of a certain vitamin or mineral. If you’re deficient in vitamin A, for instance, taking a multivitamin might not fill your nutritional gap. On the flip side, excess levels of fat-soluble vitamins A, D, E, and K—obtained from food and/or supplements—can build up in your body and become toxic, causing serious health problems.
Another drawback to multivitamins? Two important nutrients are generally either not included or included in very little amounts (≤ 250 mg): calcium and magnesium. They are considered macronutrients because we need to obtain them in large quantities. The daily requirements of calcium for men and women aged 51-70 years are 1,000 mg and 1,200 mg, respectively. For men and women of the same age group, the daily requirements for magnesium are 420 mg and 320 mg, respectively. (Compare these recommended intake values with those of the micronutrient selenium, which is 55 mcg for both men and women aged ≥ 51 years.)
So why are calcium and magnesium excluded or, at the very least, included in negligible amounts? Broadly speaking, large doses of some minerals (including calcium and magnesium) will compete with other minerals for absorption in the body.
For these reasons, single vitamin or mineral supplements tailored to support individual health goals or to address nutrient deficiencies may be preferred over multivitamins. But, for the same reasons mentioned above, here are five supplement combos you should steer clear of, making sure to take them individually at least a couple hours apart:
Calcium and magnesium
Calcium and magnesium work hand-in-hand to support bone health and other bodily functions. Magnesium is needed for calcium absorption. Because magnesium suppresses parathyroid hormone and stimulates calcitonin, it helps deposit calcium into our bones, preventing osteoporosis. Without magnesium, calcium would become toxic, depositing itself in soft tissue, which can lead to arthritis. So, you’d think that these two minerals should be taken together, right? As discussed earlier, however, taking large amounts of minerals with other minerals will reduce absorption. To maximize your calcium and magnesium supplement benefits, aim to take them at least 2 hours apart.
Copper and zinc
Both copper and zinc are imperative for optimal immune health, including internal and external healing. They work closely together to improve wound elasticity and resistance. But, zinc can interfere with copper absorption. Furthermore, high supplemental doses of zinc (≥ 50 mg/d) over the long term can cause copper deficiency. Although uncommon, copper deficiency can lead to anemia, hypopigmentation, hypercholesterolemia, connective tissue disorders, osteoporosis and other bone defects, abnormal lipid metabolism, ataxia, and higher risk of infection.
Fish oil and Ginkgo biloba
Omega-3 fish oil supplements don’t just offer heart-health benefits—they can also help with body weight and fat reduction, vision loss, and neurocognitive injury. Ginkgo biloba supplements, on the other hand, have been used for the treatment of cognitive impairment (though evidence on the efficacy of such has been mixed). What do these two supplements have in common? They both possess blood-thinning potential. Thus, taking them together can reduce or prevent blood clotting and potentially increase the risk of uncontrolled bleeding.
Iron and green tea
Iron is another key player when it comes to immune health. This element facilitates oxygen transport, hemoglobin formation, the breakdown of free radicals, and mitochondrial respiration among other processes. If you mix it with certain beverages, however, your body won’t absorb the mineral. While a glass of orange juice can help boost iron’s absorption, thanks to vitamin C, a glass of milk can have the opposite effect due to calcium’s interference.
Another antagonist? Green tea. Although the beverage may have many wonderful health benefits, enhancing iron’s bioavailability is not one of them. Researchers have shown that green tea can lead to iron deficiency anemia when consumed in large quantities. Likewise, iron has a negative impact on green tea’s efficacy. In a study led by Penn State researchers, drinking green tea after an iron-rich meal was shown to reduce green tea’s health benefits.
Melatonin and St. John’s Wort
Extracts from St. John’s Wort have been used for centuries as an analgesic agent, a sedative, and a treatment for menopausal symptoms, anxiety, and depression. St. John’s Wort has also been reported to enhance both the therapeutic and adverse effects of herbs or supplements with sedative properties when used concomitantly. Because melatonin is a well-known, potent natural sleep aid, it’s best to avoid taking it in combination with St. John’s Wort.
Plan A
Although supplements can, indeed, help address nutritional deficiencies, researchers have shown that food-sourced nutrients surpass their supplement-based counterparts when it comes to health benefits. Why? Simply put, the biologically active compounds found in these foods cannot be completely captured in a neat little pill. So, when addressing any nutritional gap, always aim to make your diet plan A.

Re: Vitamin supplements
Common sense really: a balanced diet beats a pill. But we can't always get a fully balanced diet so need to supplement now and then but some things may conflict.

Re: Vitamin supplements
Fully agree. Working away in some of the places I do, it's impossible to get a balanced diet - therefore I will always carry vitamins & supplements. Have not done me any harm, quite the opposite.
That said, with the amount of money in the industry, there'll always be the "con-merchants". Whilst expensive, I do trust Centrum and take "Silver Men 50+" (unlike Buks, I qualify
). I also take the Effervescent Tablets - vitamins and the likes of Milk Thistle.

Re: Vitamin supplements
Anti-freeze (propylene glycol), along with titanium dioxide (white paint) appears appears in many vitamins. It's listed in the ingredients on the label. You may now unroll your eyes.

Propylene Glycol is NOT "Anti-Freeze", it is an additive/ingredient in anti-freeze. Similar to above, it is also an approved ingredient in foodstuffs.

Re: Vitamin supplements
It appears that you are correct about propylene glycol and incorrect about titanium dioxide. The former has been proven to be safe for consumption in small amounts and the later is not safe for consumption. My original information came from studies pre-2005. Current studies confirm what I've said in the second sentence. I offer half an apology.pharvey wrote: ↑Sat Aug 29, 2020 3:33 pmYou like to paint things badly (pun intended) - Titanium Dioxide is used the world over in a multitude of products including foodstuffs for food safety and increasing shelf life.handdrummer wrote: ↑Sat Aug 29, 2020 2:44 pmAnti-freeze (propylene glycol), along with titanium dioxide (white paint) appears appears in many vitamins.

Re: Vitamin supplements
Just to confirm that my Order from iHerb for Chelated Magnesium which was despatched on 6th August arrived via Germany etc today, with delivery by Thai Post.The estimated arrival date was between 25th Aug and 4 Sept so all is well.
I see that others with orders routed via DHL and Germany went missing.
No duty for cost $52

Re: Vitamin supplements
Good to know, I think iHerb has some kind of 'deal' with Thai customs as there is a Thai version of the website and their boxes are clearly labelled.
