Home // 5 Dangerous Ingredients in your Vitamins and Dietary Supplements
Have you ever seen research questioning the value of vitamin and mineral supplements and wondered what the whole story was? Yes, ideally, we’d get all our holistic nutrition from food. But since most soils are deficient in nutrients, (especially minerals) due to industrial food production practices, getting all our nutrition from food is not realistic. So most of us pop vitamins and other dietary supplements to ensure we’re getting optimal levels of necessary micronutrients. Some of us pop more than others. And we’re getting handed them, just like this packet of samples my doctor recently gave me. [See photos below.]
But what if dangerous ingredients are lurking in your vitamin and mineral supplement? “No”, you exclaim. “Surely not! Those knights in shining armor at the FDA would spring into action to protect us…”
Sigh. Yet again, the political powers that should be protecting us are letting us down. And the industrial powers that be are tossing lots of lovely toxic fillers into your vitamin pills.
Here are the 5 worst (or most dangerous) things to look for in your dietary supplements. If you find them, don’t buy those supplements. Seriously. It’s best to avoid a side of carcinogen with your micronutrients. Maybe it’s all the junk in vitamins and minerals that lead to the studies questioning whether they actually help us. B vitamins with a side of Red #40 probably aren’t going to lead to an optimal health outcome.

Why, oh why are there artificial colors in your vitamins?
The FDA states that these artificial colors in your vitamins are added to: “Offset color loss due to exposure to light, air, temperature extremes, moisture and storage conditions; correct natural variations in color; enhance colors that occur naturally; provide color to colorless and ‘fun’ foods.”
Do we really care if our vitamin pill has a lovely shade of red? Especially considering the FDA itself has “probed” into the connection between artificial food dyes and children’s behavior! Red #40 has been linked to hyperactivity and the Center for Science in the Public Interest, among others, wants the FDA to ban artificial food colors. After all, artificial colors in your vitamins serve no function other than making food look more “fun”, or even worse, cover up the fact that the active ingredients in the vitamin have been degraded by exposure to light, air, moisture, heat, or poor storage conditions.
Additionally, European lawmakers now require a warning label on foods that contain artificial dyes. The label must state: “May have an adverse effect on activity and attention in children.”
Here you thought you were avoiding hydrogenated fats by passing on the margarine. Did you know that your dietary supplement may also have these little toxic nasties? And, to make matters worse, its often partially hydrogenated soybean oil—one of the major fillers in the majority of vitamins today. Unless soy is organic, you can pretty much guarantee it’s genetically modified. So you’re getting a dose of franken-soy with your vitamins.
The FDA knows that hydrogenated fats are bad for us. The 2010 Dietary Guidelines for Americans specifically states: “Keep trans fatty acid consumption as low as possible by limiting foods that contain synthetic sources of trans fats, such as partially hydrogenated oils, and by limiting other solid fats.”
The CDC chimed in, posting in January 2014 that:
Consuming trans fat increases low-density lipoprotein (LDL, or ‘bad’) cholesterol. This risk factor contributes to the leading cause of death in the U.S. – coronary heart disease (CHD). Trans fat may also have other adverse health effects like decreasing high-density lipoprotein (HDL, or ‘good’) cholesterol. Further reducing trans fat consumption by avoiding artificial trans fat could prevent 10,000-20,000 heart attacks and 3,000-7,000 coronary heart disease deaths each year in the U.S.
So why does the FDA allow these dangerous ingredients in your supplements? They’re cheap fillers. People still have this idea that bigger is better. Until we realize that smaller can be just as good, manufacturers will use cheap nasty fillers to give us bigger horse sized pills.
It’s up to you to avoid them, folks.
Essential fatty acids (EFAs) are on everyone’s mind lately. They’ve been shown to be particularly important for pregnant women, babies, and toddlers,  as well as for brain and heart health.  But not all brands are created equal. Since fish high on the food chain can accumulate mercury, lead, and other contaminants, those metals can make their way into your fish oil supplements. Yuck! Maybe these contaminants are the reason some research showed that fish oil supplements increased prostate cancer risk? 
The high levels of PCBs in fish oils led to a lawsuit in California in 2010 claiming that supplement manufacturers should have placed warning labels stating the cancer risk on their fish oil supplements.  Testing by Consumer Reports in 2011 showed 1/3 of the fish oils tested had high PCB levels. 
What? You don’t want a toxic heavy metal or some PCBs with your EFAs today? Then you’d better be careful of what brand of Omega-3 or EFAs you buy. This is not the time to choose the cheap option—make sure that you choose a variety that has been meticulously tested for lead or mercury contaminants. Your best choices should state that they are “Molecularly distilled and 3rd party tested to ensure PCBs, dioxins, mercury, lead and other contaminants are below acceptable limits set by the Council for Responsible Nutrition and other advisory agencies,” or something similar.
Here’s an even better option: choose wild fish, pasture-raised eggs, or greens for a good dose of Omega-3s!
Talc is not currently considered food grade by the FDA. Although they were considering setting upper limits for asbestos fibers and adding it to the GRAS list way back in 1979, I couldn’t find whether any upper limits have yet been set. (Mind you, the FDA website is pretty impossible to navigate!) But talc is still found in supplements. Yuck!
Titanium dioxide is yet another one of the nasty and dangerous ingredients in your vitamins or supplements; it is used as a colorant (it’s also used in many cosmetics). Titanium dioxide has a raft of health implications.
Titanium dioxide has been shown to cause lung inflammation and damage, so it’s yet another substance that has an impact on workers at the production level. It has also been implicated in immune system function, with some studies showing DNA damage by Titanium dioxide nanoparticles, albeit marginal damage. Just a wee bit of DNA damage with your vitamins.
Taken internally, it has been shown to cause kidney damage in mice and to induce small intestine inflammation. This is scary considering how many people suffering from Crohn’s and gluten sensitivity are probably taking supplements containing Titanium dioxide.
Yet again, our health is risked so our vitamins can be a pretty color. Very disturbing. Avoid it.
The big picture solution is to have an FDA that actually prevents toxic materials getting into our food supply (and dietary supplements are a part of that food supply). But since that seems unlikely anytime soon, we have to take matters into our own hands:
If we all kick up a bit of a ruckus, manufacturers will take these dangerous ingredients out.
