As with anything else, usually quality varies widely. With supplements it is essential to know the details for each. There are many versions of some nutrients. Some versions cannot be absorbed well by the body and a few may actually have detrimental effects to certain individuals or populations.
In general, with all supplements, be sure to choose products that are free of maltodextrin as a binding agent or filler. This is common in many powder supplement capsules and there just isn’t a good reason to choose these. Also, look out for gelatin capsules. In speaking with glyphosate (aka RoundUp®) experts/researchers that are investigating the herbicide’s effect on animals/human health, 100 out of 100 gelatin capsules, from a wide variety of supplement manufacturers, tested positive for the chemical.
Lastly, just because a supplement is popular doesn’t necessarily mean that it is a good fit for you. Fish oil for example is an incredibly common choice for people seeking its reported anti-inflammatory effects. However, research in Canada led by Sanjoy Ghosh, PhD at UBC has shown that it can cause problems when it reaches the GI. Most importantly fish oil disrupts the microbiome and can cause inflammation that originates in the gut.
Here are the top supplements purchased last year and what you should consider with each:
Multivitamins with the folic acid version of folate are to be avoided, as are those multivitamins that contain the cyanocobalamine variety of vitamin B12. Also, choose only vitamin D3 or cholecalciferol NOT vitamin D2 or ergocalciferol.
Be sure to avoid multivitamins with large amounts of calcium. This mineral is important but when part of a multivitamin it generally disrupts our ability to absorb the smaller amounts of trace minerals present.
