What to Look For When Buying Nutritional Supplements

What to Look For When Buying Nutritional Supplements

pillsThere are quite literally hundreds of different brands of nutritional supplements (also called dietary supplements) on the market today, and it’s difficult for the average consumer to tell the difference between one and another. Each manufacturer claims that its products are supportive of your health, but how can you really determine if a nutritional supplement is safe and effective? Then there’s the price tag. Brands vary considerably in cost—one multivitamin may cost 20 cents per day, whereas another can cost a whopping $7.50! How can you decide whether it’s worth it? Our goal is to provide you with some practical advice—basic facts combined with a few do’s and don’ts—that you can use to be a more educated consumer if you decide to buy nutritional supplements.

Just because a nutritional supplement is “natural” does NOT necessarily mean it is safe. There are plenty of products that can be dangerous if you suffer from certain health conditions, use them along with certain other foods, medicines or supplements, or take them incorrectly. Even if you avoid interactions and take a supplement correctly, it is still possible for your body to have a negative reaction to a supplement. If this happens, stop taking the supplement immediately and see your doctor.

The FDA regulates dietary supplements very lightly. A supplement manufacturer does not need FDA approval to put its products on the market, but the FDA is responsible for monitoring the products’ safety, removing them only if they have caused problems. However, the FDA does require that manufacturers follow “good manufacturing practices” for processing and that they meet quality standards. This includes ensuring that the supplement contains the stated amount of ingredients and that it is free from contamination from things such as pesticides and heavy metals.

One thing to look for in a nutritional supplement is the “USP Verified” seal of approval. This is given to products that meet the stringent requirements for quality, purity and potency as established by the non-profit group U.S. Pharmacopeia.

The form in which you take your dietary supplements may also make a difference. Tablets tend to contain more fillers and binders than capsules because the powder they are made from must stick together in a regular mass. They may also be coated to keep it from falling apart and to make swallowing easier. They may also have added coloring and flavoring to make them more palatable. All else equal, it usually makes sense to avoid these. Capsules or gel caps are more likely to be free from excess fillers and binders. But if you are vegetarian or vegan, be sure to read the label to ensure the capsules are not derived from animal sources (cellulose is the most common vegan-friendly form of capsule).

Always read the product’s label thoroughly to see exactly what each supplement contains. While buying the most expensive supplement obviously won’t guarantee its quality or effectiveness, it is often true that you get what you pay for. Cheap supplements are frequently made from inferior ingredients or those that cost less to manufacture, and are often less readily absorbed by the body. Who wants to pay for supplements only to have them flushed down the toilet? A high-quality supplement will be more bioavailable, which is what you’re taking it for in the first place!

As with most other products, it usually pays to do a little homework before choosing a manufacturer and buying a supplement. Above all, you’ll want a manufacturer who has a good reputation and stands behind its products. Good companies will stress their excellent quality control and will be happy to provide you with independent evaluations of their products. Many chiropractors have specialized training and experience related to nutrition, and can help you decide which dietary supplements might be right for you.

Benefits of Copper

Benefits of Copper

Grinding for Pennies - Wood mortar, pestle & pennies.Like some of the other essential dietary minerals, copper is needed only in trace amounts for your body to function properly. Nevertheless, copper is vital to many of the body’s functions, so it is important to ensure that you are not copper deficient (which is actually quite rare). Since the human body cannot synthesize copper on its own, it must be absorbed by the body from the food we eat.

Copper combines with protein to produce enzymes that spur a wide range of bodily functions. It plays a key role in energy production, supports the brain and central nervous system, and helps in the creation and metabolism of neurotransmitters. It also is important in the formation of connective tissue (including that of the heart and blood vessels) and plays a part in bone formation. It is necessary for proper iron metabolism and the healthy formation of red blood cells. It is also responsible for the production of melanin, the pigment that gives color to the skin, eyes and hair. Copper acts as an antioxidant and is important for a healthy immune system.

As mentioned earlier, copper deficiency is relatively uncommon. However, some people are more prone to a deficiency than others. This includes those who have cystic fibrosis, severely restricted diets, or problems with absorption through the gut (such as individuals with celiac disease). Infants and the elderly are also more prone to copper deficiency. Infants may be more at risk they have been fed only cow’s milk formula (cow’s milk is very low in copper).

The recommended daily intake of copper is as follows:

Infants, birth to 6 months: 200 mcg/day

Infants, 7 – 12 months: 220 mcg/day

Children, 1 – 3 years: 340 mcg/day

Children, 4 – 8 years: 440 mcg/day

Children, 9 – 13 years: 700 mcg/day

Adolescents, 14 – 18 years: 890 mcg/day

Adults, 19 years and older: 900 mcg/day

Pregnant women: 1,000 mcg/day

Breastfeeding women: 1,300 mcg/day

Being deficient in copper can contribute to anemia and osteoporosis as well as a variety of other health problems. However, having too much copper in your system can actually be toxic. Signs of copper toxicity include nausea, vomiting, diarrhea and abdominal pain that can eventually lead to kidney and liver failure, coma and death. Taking high amounts of zinc can lower copper levels that have become too high.

Children should get the copper they need from their diet rather than from supplements. Adults who are considering taking a copper supplement should consult with their doctor before doing so, since it is important not to get too much copper, and it must have a proper balance with zinc. Foods rich in copper include liver, nuts (particularly cashews, almonds and Brazil nuts), seeds, legumes, clams and oysters.

 

When It Comes to Nutritional Supplements, Quality Counts!

When It Comes to Nutritional Supplements, Quality Counts!

Nutritional supplements are one way that many of us try to improve our health and to support our efforts to lose weight, stop smoking, and more. Although using good quality supplements can be beneficial to your health, it can be difficult to determine which ones really fit the bill. Supplement makers are lightly regulated relative to the pharmaceutical industry, and there have been specific ingredients and some products pulled from the store shelves only after they have proved harmful to a number of people. When the New York Attorney General recently revealed the results of a probe into supplement sales at four top national retailers and found that many products didn’t actually contain the correct ingredients, it came as no surprise to some experts who have worried about poor quality control and manufacturer fraud for years.

A Matter of Omission

While many of us might be more concerned about what’s in a supplement that shouldn’t be, it can also be a big problem if the product doesn’t actually contain the key ingredients listed on the label. If an individual is depending on a particular supplement to remain healthy, the lack of key ingredients could have serious consequences that the user may not be aware of. In a number of cases, key ingredients had apparently been replaced with cheap fillers or other alternatives that not only failed to meet the specific nutritional need but that also had the potential to cause harm to some consumers.

Herbal Ingredients: What You May Not Know

Many supplements use herbs in their products as their main ingredients. Because these herbs are “all natural”, many people mistakenly believe that they cannot harm you or have side effects similar to those of prescription drugs. In reality, herbs can and do interact with each other, with other foods and with medications to produce unexpected results. And this is true even when nutritional supplements are properly labelled. When supplements are manufactured poorly and/or deliberately misrepresented through their labeling, this can make matters even worse.

Need an example? Consider the consumer who believes that she is purchasing an herbal supplement that is wheat-free when. Now suppose that the supplement contains NONE of the herb listed as the primary ingredient but that it DOES contain wheat. If the consumer has a wheat allergy or is on a gluten-free diet, taking these supplements could cause health problems that would be both serious and completely unexpected. In the New York Attorney General’s investigation, some of the products that were found to be improperly labeled were:

  • Ginkgo Biloba
  • John’s Wart
  • Valerian Root
  • Probiotics
  • Ginseng
  • Garlic
  • Saw Palmetto
  • Echinacea

Protecting Yourself from Low Quality Supplements

By now it should be clear that choosing a nutritional supplement isn’t only a matter of selecting the right type to get the health benefits you’re looking for. It’s also a matter of purchasing a high-quality product that contains ONLY what it should. However, the current regulatory approach—essentially self-regulation–doesn’t inspire confidence and leaves consumers more vulnerable to shortcuts in manufacturing and quality control as well as deliberate misrepresentation or fraud.

What can be done? Several very well-regarded companies manufacture high-quality nutritional supplements to the same standard as heavily regulated pharmaceutical firms. Many of these companies distribute their products exclusively through the offices of healthcare professionals, including chiropractic physicians and nutritionists.
