Telomere length has been associated with aging, age-related diseases, adverse conditions, and mortality. Moreover, studies in humans suggest a causal role of short telomeres or accelerated telomere shortening in disease and mortality risk. A previous cross-sectional study has shown that Shaklee supplement usage significantly improved various health parameters and nutritional status. [1] The objective of the current cross-sectional study was to explore the effect of dietary supplementation on telomere length.

The normal range of telomere lengths was determined from saliva samples in a population of healthy, non-smoking subjects aged 33-80 from the San Francisco Bay Area (control group; n=324; 147 males and 177 females) who took no more than 3 supplements daily. The telomere lengths of heavy supplement users (supplement group; n=80; 21 males and 59 females), the majority of whom took more than 12 Shaklee supplements at least 4 days per week, were compared to the age-matched control group. Disease and smoking status were not exclusion criteria for the supplement group. Telomere length was measured by quantitative PCR to determine the telomere-to-single copy gene (T/S) ratio. Change in T/S ratio over time was fitted to a linear regression. Blood biomarkers were also assessed.

Overall, women had longer telomeres than men in the control group, but this trend was reversed in the supplement group. (Refer to Figures 3 & 4 below) T/S ratio of the supplement group was 11.2% greater than that of the control group (p<0.0001). Supplementation resulted in a greater treatment effect in men vs. women (p<0.005). By linear regression, the rate of change in T/S ratio was reduced by 40% in the supplement group vs control. Blood biomarkers in both groups were comparable and were within the normal physiological ranges.

New study suggests Vitamin D recommendations miscalculated

By |March 24, 2015|Vitamin D|

Source CTV News

We need far more vitamin D than previously thought, according to two teams of researchers from Canada and the US.

The Recommended Dietary Allowance (RDA) for vitamin D is ten times lower than what we actually need, say two teams of researchers who have challenged the US’s National Academy of Sciences (NAS) and the Institute of Medicine (IOM), both responsible for the RDA.

“The error has broad implications for public health regarding disease prevention and achieving the stated goal of ensuring that the whole population has enough vitamin D to maintain bone health,” says Dr. Cederic Garland, an adjunct professor at University of California, San Diego.

Currently the RDA for vitamin D established by the IOM is 600 international units per day until we reach 70 years of age, and 800 IU per day thereafter.

A Canadian research team reviewed each of the 10 studies the IOM used to arrive at their RDA and their calculations revealed that 600 IU of vitamin D per day puts only half of the amount that they had assumed in the blood.

In scientific terms, that means that 97.5 per cent of individuals will have serum 25 values of vitamin D above 26.8 nmol/L rather than above 50 nmol/L as the IOM had thought.

To get a serum 25 value of vitamin D of at least 50 nmol/L, you could need up to 8895 IU per day, according to the study.

Dr. Garland’s team of US researchers wrote a letter confirming the Canadian team’s findings, in which they suggest a slightly more conservative RDA.

“We call for the NAS-IOM and all public health authorities concerned with transmitting accurate nutritional information to the public to designate, as the RDA, a value of approximately 7,000 IU/day from all sources,” wrote Dr. Garland and his colleagues.

Dr. Garland added that the number is well below the 10,000 IU currently considered safe by the IOM for teenagers and adults.

Two versions exist: Vitamin D2, known as ergocalciferol, and vitamin D3, also known as cholecalciferol, which is thought to be the more potent and favorable version of the two.

Fatty fish, such as salmon, tuna, sardines and cod liver oil contain hearty amounts of vitamin D3, yet most vitamin D3 is synthesized in the skin upon sun exposure, according to the World Health Organization.

Cereals, cheese and milk could be an important source of both types of vitamin D depending upon where you live yet because they are often fortified with synthetic versions and the amounts may vary.

Vitamin D is important for skin, bone and heart health and deficiencies can result in rickets and abnormal skin pigmentation, yet side effects of excess intake are rare and minimal, according to WebMD.

Both the study and the letter were published in the journal Nutrients.

In a single-subject experiment undertaken on 14 consecutive patients, the effects of acupuncture, cervical manipulation, no therapy, and NSAID-percutan application on kinesthetic sensibility, dizziness/vertigo and pain were studied in patients with dizziness/vertigo of suspected cervical origin. The ability to perceive position of the head with respect to the trunk was studied. The effects of different forms of therapy-and none-on dizziness and neck pain were compared, using a 100 mm visual analogue scale (VAS). Active head relocation by subjects with dizziness was significantly less precise than in the control group. Manipulation was the only treatment to diminish the duration of dizziness/vertigo complaints during the past 7 days and increased the cervical range of motion.

OBJECTIVE:   The purpose of this study was to evaluate the efficacy of manipulative and manual therapy treatments with regard to pain perception and neck mobility in patients with tension-type headache.

METHODS:   A randomized clinical trial was conducted on 84 adults diagnosed with tension-type headache. Eighty-four subjects were enrolled in this study: 68 women and 16 men. Mean age was 39.76 years, ranging from 18 to 65 years. A total of 57.1% were diagnosed with chronic tension-type headache and 42.9% with tension-type headache. Participants were divided into 3 treatment groups (manual therapy, manipulative therapy, a combination of manual and manipulative therapy) and a control group. Four treatment sessions were administered during 4 weeks, with posttreatment assessment and follow-up at 1 month. Cervical ranges of motion pain perception, and frequency and intensity of headaches were assessed.

RESULTS:   All 3 treatment groups showed significant improvements in the different dimensions of pain perception. Manual therapy and manipulative treatment improved some cervical ranges of motion. Headache frequency was reduced with manipulative treatment (P < .008). Combined treatment reported improvement after the treatment (P < .000) and at follow-up (P < .002). Pain intensity improved after the treatment and at follow-up with manipulative therapy (P < .01) and combined treatment (P < .01).

BACKGROUND:   Research involving chiropractors is evolving and expanding in Europe while resources are limited. Therefore, we considered it timely to initiate a research agenda for the chiropractic profession in Europe. The aim was to identify and suggest priorities for future research in order to best channel the available resources and facilitate advancement of the profession.

METHODS:   In total, 60 academics and clinicians working in a chiropractic setting, and who had attended any of the annual European Chiropractors’ Union/European Academy of Chiropractic (ECU/EAC) Researchers’ Day meetings since their inception in 2008, were invited to participate. Data collection consisted of the following phases: phase 1 identification of themes; phase 2 consensus, which employed a Delphi process and allowed us to distill the list of research priorities; and phase 3 presentation of the results during both the Researchers’ Day and a plenary session of the annual ECU Convention in May 2013. In addition, results were distributed to all ECU member countries.

RESULTS:   The response rate was 42% from phase 1 and 68% from phase 2. In general, participants were middle-aged, male and had been awarded a Doctor of Philosophy (PhD) as well as chiropractic degree. Approximately equal numbers of participants had obtained their chiropractic degree from the UK/Europe and North America. The majority of participants worked primarily in an academic/research environment and approximately half worked in an independent institution. In total, 58% of the participants were from the UK and Denmark, collectively representing 44% of the chiropractors working in Europe. In total, 70 research priorities were identified, of which 19 reached consensus as priorities for future research. The following three items were thought to be most important:

1) cost-effectiveness/economic evaluations,

2) identification of subgroups likely to respond to treatment, and

3) initiation and promotion of collaborative research activities.

Inappropriate Use of the Title Chiropractor and Term Chiropractic Manipulation in the Peer-reviewed Biomedical Literature

OBJECTIVE:  This study was conducted to determine how the words chiropractic and chiropractor have been used in publications in relation to the reporting of complications from cervical spinal manipulation therapy (SMT).

STUDY DESIGN:  The study method was to collect recent publications relating to spinal manipulation iatrogenesis which mentioned the words chiropractic and/or chiropractor and then determine the actual professional training of the practitioner involved.

METHOD:  The training of the practitioner in each report was determined by one of three means: surveying previous publications, surveying subsequent publications and/or by writing to the author(s) of ten recent publications which had used the words chiropractic and/or chiropractor.

RESULTS:  This study reveals that the words chiropractic and chiropractor commonly appear in the literature to describe SMT, or practitioner of SMT, in association with iatrogenic complications, regardless of the presence or absence of professional training of the practitioner involved.

CONCLUSION:  The words chiropractic and chiropractor have been incorrectly used in numerous publications dealing with SMT injury by medical authors, respected medical journals and medical organizations. In many cases, this is not accidental; the authors had access to original reports that identified the practitioner involved as a non–chiropractor. The true incidence of such reporting cannot be determined. Such reporting adversely affects the reader’s opinion of chiropractic and chiropractors.

From the Full-Text Article:


Among the health professions, chiropractic has an impressive safety record for its 99-yr existence [1, 2]. Chiropractors in Australia are aware that complications can occur after spinal manipulation therapy (SMT), and, as responsible professionals, they have investigated and instituted procedures to minimize their occurrence [2-19]. In fact “the incidence and mechanisms are better reported in the chiropractic literature than elsewhere” [20].
