One thing that I find is how consumers get confused about which supplements are the best to buy and what’s the difference between them all? I don’t blame them, the amount of supplements on the market is quite daunting and when having to choose one for yourself it can be overwhelming. Normally the best advertising campaign wins. But that doesn’t necessarily mean it’s the best for you.
Let’s look at calcium supplements. An essential mineral, in particular for adults over 50 years.
Two of the most popular brands on the market contain calcium carbonate. This form of calcium has a low absorption and is dependant on stomach acid for breakdown and must be eaten with meals otherwise it is pretty much useless. One 1000mg tablet of calcium carbonate has 400mg of elemental calcium. The bioavailability of the 400mg, is less than this as the body only absorbs a small amount. Another form of calcium, calcium citrate has been found to have an absorption rate of approximately 25% greater than calcium carbonate.
Of course dietary calcium is far superior to a supplement but there are certainly some life stages where a supplement is required.
Also on side note, some of the retail supplements out there contain titanium dioxide to make it nice and white. Titanium dioxide dust, when inhaled, has been classified by the International Agency for Research on Cancer (IARC) as an IARC Group 2B carcinogen, meaning it is possibly carcinogenic to humans. I know we are not inhaling these tablets but they are being ingested into the bodies…..best to steer clear.
