Vitamin D, fish oil dietary supplements and weight coaching have lengthy been touted for his or her well being advantages, however for wholesome seniors, none of them — both together or alone — boosts bodily or psychological efficiency or prevents damaged bones, Swiss researchers report.

For 3 years, they tracked greater than 2,100 males and ladies (common age: 74) who had been randomly assigned to a program involving a number of of the three well being interventions.

The upshot: “The results suggest that additional vitamin D and omega-3 [fish oil] intake in active 70-plus adults without previous illnesses, carries no benefit for the risk of non-vertebral fractures, or for muscle and memory function,” mentioned research chief Dr. Heike Bischoff-Ferrari, head of geriatrics and growing older analysis at College Hospital Zurich.

However the takeaway was not solely discouraging.

Ongoing evaluation suggests taking a gram a day of fish oil lowered seniors’ total an infection threat by 11%. And a few particular an infection dangers dropped much more — together with a dramatic 62% discount in urinary tract infections, a standard ailment in older of us.

Even when their threat of damaged bones was unimproved, contributors who took 2000 IUs of vitamin D each day noticed a “significant” drop of their systolic (higher) blood stress readings, Bischoff-Ferrari mentioned. Vitamin D supplementation was additionally linked to a 16% drop in total an infection threat amongst 70- to 74-year-olds.

“In view of the safety and affordability of the supplements, as well as the high mortality rate from infections in older adults, these results are relevant for public health,” she mentioned.

Researchers additionally examined the impression of two train regimens: a strength-training program and an “attention control exercise program” for joint flexibility. Every concerned three 30-minute periods per week. Some contributors both exercised or took dietary supplements; others did a mixture of each.

For contributors with out main preexisting well being issues, researchers discovered no statistically vital well being profit from the regimens. They mentioned most contributors began the research in wonderful form, which can have restricted the prospect to point out greater advantages.

“Over 80% were moderately to highly physically active, and about half were healthy agers without comorbidities,” Bischoff-Ferrari mentioned. “In fact, all participants over the three years improved their blood pressure, their cognitive function and their lower extremity function.”

One other complicating issue could be the quantity of every day supplementation that was examined, mentioned Lona Sandon, director of scientific vitamin at College of Texas Southwestern Medical Middle in Dallas, who reviewed the findings.

“One of my first thoughts on this study is: Was the dose of intervention enough to cause a difference?” Sandon mentioned. “The vitamin D dose was only 2000 IUs … [which is] considered the current upper limit for vitamin D. However, there is much scientific controversy about just how much vitamin D really is the upper limit and needed to alter blood levels. We make much more vitamin D from sunlight than this.”

The fish oil dose was additionally comparatively low, Sandon famous. Research exhibiting profit for issues like reducing irritation use a lot increased doses, and power coaching was additionally under present suggestions of two hours per week, she added.

“Only about two-thirds of the participants self-reported meeting the 30-minutes, three days/week [requirement],” Sandon identified. “So do the results surprise me? Not at all with those doses.”

Her backside line: “Getting adequate vitamin D in food and from sunshine is good for us and essential,” Sandon mentioned. “Omega-3s are essential nutrients for the body and proper functioning, too. Exercise does help keep us physically and mentally functioning better. People should not give up on eating healthy and keeping moving. I do not see a downside to any of these things.”

The findings had been revealed Nov. 10 in Journal of the American Medical Affiliation.
