Vitamin D Supplements: Is What You See What You Get?

By Denise Mann

HealthDay Reporter

MONDAY, Feb. 11 (HealthDay News) -- Many vitamin D supplements may not contain what their label says they do, a new study warns.

Some pills may pack a lot more vitamin D than the label states, and others may provide markedly less, according to the findings, published in a research letter Feb. 11 in JAMA Internal Medicine.

The researchers are more concerned by pills delivering too little of the vitamin than pills providing too much.

"It can be hard to overdose on vitamin D," said study author Dr. Erin LeBlanc, an endocrinologist and researcher with the Kaiser Permanente Center for Health Research in Portland, Ore. However, the findings "may be a concern for those who have been told by their doctor to take vitamin D if their chosen supplement does not have the amount listed."

Vitamin D is known as the sunshine vitamin because it is produced in response to exposure to natural sunlight. This nutrient is also added to milk and other foods, and is available in small amounts in fatty fish, beef liver, cheese, and egg yolks. Still, it can be challenging to get as much D as needed through diet, so supplements are often recommended. Some researchers have linked vitamin D deficiency to the bone disease osteoporosis, heart disease and some types of cancer.

Exactly how much vitamin D people need has been somewhat controversial in recent years. The independent, not-for-profit Institute of Medicine recommends 600 international units (IU) a day for teens and adults, or 800 IU for those older than 70. Some groups feel that this bar was set too low.

In the new study, researchers analyzed 55 over-the-counter bottles of vitamin D supplements from 12 manufacturers. They also tested vitamin D pills made at a compounding pharmacy, which creates individualized drugs. The manufacturers were unidentified.

Overall, the amount of vitamin D found in the supplements ranged from 9 percent to 146 percent of what was listed on the label.

When LeBlanc and colleagues tested five pills from the same bottle, the supplements had anywhere from 52 percent to 135 percent of the stated amounts. When five pills were averaged, however, two-thirds were within the stated range.

Although the vitamin supplement industry remains largely unregulated, some manufacturers volunteer to have the quality of their supplements tested by the independent, not-for-profit U.S. Pharmacopeial Convention (USP), which sets standards for supplements.

One of the study samples had USP verification. "Generally, the pills that were from this manufacturer were more accurate," LeBlanc said.

Supplements from compounding pharmacies were the least accurate, LeBlanc said.

Duffy MacKay, vice president of scientific and regulatory affairs at the Council for Responsible Nutrition in Washington D.C., a trade group representing supplement manufacturers and ingredient suppliers, said that there is no excuse for supplements to deviate from their labels. Still, he said, "I am comforted that there are no safety concerns."

C-Section, Formula May Disrupt 'Good' Gut Bacteria in Babies

By Amanda Gardner

HealthDay Reporter

MONDAY, Feb. 11 (HealthDay News) -- Being born by cesarean section has been tied to higher risks for various health problems in children, and now a new study finds these babies also have fewer "good" bacteria in their digestive tract.

Similarly, babies who were exclusively or even partially formula-fed rather than breast-fed also had markedly different gut flora than babies who were breast-fed, according to the study appearing in the Feb. 11 issue of the CMAJ (Canadian Medical Association Journal).

"Since other [researchers] have found associations between cesarean section delivery or formula-feeding and infant gut changes and conditions like allergy [and] asthma, we speculate that our observations may lead to poor health in later life," said study senior author Anita Kozyrskyj.

The findings support current clinical practice guidelines which favor vaginal delivery whenever possible, added Kozyrskyj, who is research chair and an associate professor of pediatrics at the University of Alberta, in Edmonton.

About a third of all U.S. births occur by C-section, a number considered by many to be far too high and potentially harmful to both the child and the mother.

Vaginal delivery, among other advantages, fosters the growth of trillions of good bacteria that reside peacefully in the human body (collectively know as a person's microbiome), many of them in the intestine.

Meanwhile, C-sections interfere with the newborn's exposure to bacteria in the vaginal tract, bacteria that essentially trains the immune system to react appropriately to future events, according to study background information.

Mothers who have C-sections also tend to start breast-feeding later and require antibiotics, both of which could also affect the baby's microbiome.

In the new study, researchers analyzed DNA from fecal samples taken from 24 healthy infants in four Canadian provinces at 4 months of age.

Compared with children who had been born vaginally, children who had been delivered by C-section had less diverse flora, lower levels of Shigella bacteria and none of the bacteria known as Bacteroides at all.

"Shigella and Bacteroides are organisms picked up from mom and considered first colonizers," Kozyrskyj explained. "They lay the foundation for further microbes that become part of our normal microbiome."

Meanwhile, infants who were fed formula as opposed to breast milk also had less diverse flora and, in addition, had more of the bacteria Clostridium difficile, which had been associated with the development of allergies.

The study was a small one, but the researchers have collected fecal samples on 200 children and will be analyzing those in the future. They hope to eventually enroll 2,500 children in the study.

It's too soon to say definitively that the changes in the gut microbiome of children born by C-section will develop health problems. And it's possible that changes in the bacterial composition of the intestine as people age will compensate for diminished levels of bacteria in newborns, Kozyrskyj added.

A pediatric expert praised the new study.

"This is an important first step to make an association between intestinal bacteria and mode of delivery and type of feeding," said Dr. Michael Morowitz, a pediatric surgeon with Children's Hospital of Pittsburgh, at the University of Pittsburgh Medical Center.

Although follow-up studies will be needed, Morowitz added, "This is the latest piece of pretty convincing evidence that determinants very, very early in life can have an impact that lasts for months or years."
