How to Choose an Effective Nutritional Supplement

How to Choose an Effective Nutritional Supplement

The supplement industry has become an incredibly large business where numerous competing brands find their place on the health food stores’ shelves.

Hundreds of online stores offer wide ranges of nutritional supplements as well. When one is faced with the simple question of “which vitamin C or multivitamin to choose?” – the answer may not be as straightforward as initially thought. The simple guidelines below are meant to help a lay person navigate the world of nutritional supplements to eventually choose an effective supplement that helps with symptom-relief.


Unfortunately, there is no regulating body for nutritional supplements such that many false claims can be made on the packaging of any supplement and poor quality formulation find their way alongside better quality products. Consumers need to be very discerning to buy a supplement that will deliver results while fitting into a reasonable budget. To counter this problem, several websites have made it their mission to provide independent reviews of various supplements, making the choice easier for consumers.

Good brands of supplements will typically not include excessive amounts of fillers and their products are typically free of gluten, dairy, soy or egg and nut residues. Products that contain these potential allergens are oftentimes the low-quality ones. In addition, we do not like to see artificial flavouring, food colouring or sweetening agents such as high-fructose corn syrup, glucose syrup, or sucrose in any supplement. The only exception to this would be for products devised for children – in which case glycerin or stevia are acceptable sweeteners.

Look at Fillers

When one buys a multivitamin, it is good to know that vitamins and minerals come in different forms where each compound has a different absorption rate by the body. Evidently, one ideally wants to purchase a product that contains active nutrients in their most absorbable form. We know for instance that calcium carbonate and magnesium oxide – found in most readily available calcium and magnesium supplements – are poorly absorbed by the body. Better form of those minerals would be calcium and magnesium citrates, glycinates or amino acid chelates. Vitamin B12’s cheapest form is cyanocobalamin but methylcobalamin is much more readily absorbed into the body. Pyridoxine, or vitamin B6, is superior when found in its activated form – pyridoxal-5-phosphate and folic acid should now come as methyfolate. Be sure to pick a product that combines these nutrients in their best forms.

Compare Active Ingredients

Several nutritional supplements do not contain enough of the active nutrient to make any difference. This is unfortunately a very common problem. The dosages below are the minimal amount to really make any difference in terms of symptom relief:

  • Vitamin C: 1000 mg
  • Magnesium: 200 mg
  • Calcium: 400 mg
  • Zinc: 15 mg
  • Methylcobalamin (vitamin B12): 1000 micrograms
  • Vitamin E: 400 IU
4)Make Sure the Dosage is Sufficient

Probiotics – which are encapsulated beneficial intestinal bacteria – have become a very popular supplement. The large intestine naturally hosts about 150 trillion bacteria and a research shows that the intestinal flora of healthy individuals differs significantly from that of people with health issues. As such, probiotics in supplemental form can be a useful adjunct to any treatment plan since the nature of our microbiome seems to contribute to the development or prevention of a vast range of health concerns – from obesity, to cardiovascular illness and digestive concerns. A high-quality general probiotic should contain at least 5 different strains. Research has shown that a healthy microbiome is one that hosts a variety of different types of bacteria. As such, products that only feature one strain can be useful if one is looking at a very targeted intervention – for instance, the lactoGG strain in the treatment of antibiotic-induced diarrhea – but if the probiotic is meant for general health promotion, then several strains are more useful. The product should contain at least 25 billion colony-forming units per serving, if not more. Indeed, because our colon hosts 150 trillion bacteria, the probiotic supplement will only make a difference if it contains bacteria in sufficient amount. One must recall that many of the bacteria from the capsule will die on their way to the colon, particularly in the stomach where the low pH is meant to kill ingested bacteria and other pathogens. Some formulations ally bacteria and their food – a special type of fiber called prebiotics – while others do not. Products with prebiotics are generally not a bad idea, except for individual who tend to symptoms typical of irritable bowel syndrome (flatulence and irregular bowel movements).

Choosing a Probiotic Supplement

With these simple 5 rules, it becomes easy to choose the right nutritional supplement. For products that are less common than simple vitamin, mineral and probiotic supplements, it is a good idea to consult with a health care practitioner trained in nutrition. The world of nutritional supplements is indeed vast and it takes a great deal of knowledge to stay updated on the available choices!

  1. In recent years in Europe and in the United States, the use of so-called “probiotic” food products has spread widely, They come in the form of dietary supplements, yoghurt drinks or “diet” snacks, and are sold in supermarkets and pharmacies without a prescription. In Europe and the United States these products are regulated with precise criteria – in other countries there are basic guidelines for their trade and consumption spread by the Ministry of Health – but since they are considered normal foods they are advertised in a rather creative way. In Italian advertisements, for example, they are associated with slogans such as “favors the balance of intestinal flora” or “helps strengthen your immune system” and other rather demanding phrases. The question I have in mind is: do they really do something, these probiotics?

    1. Probiotics currently on the market are very different from one another, it is therefore possible to choose to buy one based on the current research conducted on its main substance. Some probiotics contain strains that survive the passage through the intestinal tract and therefore can have beneficial effects.

  2. The top advice I can give, as one’s who as tried them all, not to rely on the low price, but to choose a supplement appropriate to their needs instead of the cheaper product.
