    Consumption of one egg per day increases serum lutein and zeaxanthin concentrations in older adults without altering serum lipid and lipoprotein cholesterol concentrations. Goodrow EF, Wilson TA, Houde SC, Vishwanathan R, Scollin PA, Handelman G, Nicolosi RJ. J Nutr. 2006 Oct;136(10):2519-24. PMID: 16988120 These findings indicate that in older adults, 5 wk of consuming 1 egg/d significantly increases serum lutein and zeaxanthin concentrations without elevating serum lipids and lipoprotein cholesterol concentrations.

    A preliminary study of the safety, feasibility and cognitive efficacy of soy isoflavone supplements in older men and women. Gleason CE, Carlsson CM, Barnet JH, Meade SA, Setchell KD, Atwood CS, Johnson SC, Ries ML, Asthana S. Age Ageing. 2009 Jan;38(1):86-93. Epub 2008 Dec 2. PMID: 19054783 doi:10.1093/ageing/afn227 Conclusions: these data suggest that administration of 100 mg/day of isoflavones was well tolerated. Plasma genistein and daidzein levels, but not equol, increased with isoflavone administration. Finally, data support the potential cognitive effects of soy isoflavones in older adults.

    Consumption of 2 and 4 egg yolks/d for 5 wk increases macular pigment concentrations in older adults with low macular pigment taking cholesterol-lowering statins. Vishwanathan R, Goodrow-Kotyla EF, Wooten BR, Wilson TA, Nicolosi RJ. Am J Clin Nutr. 2009 Nov;90(5):1272-9. Epub 2009 Sep 16. PMID: 19759170 Conclusions: Consumption of 4 egg yolks/d, and possibly of 2 egg yolks/d, for 5 wk benefited macular health in older adults with low MPOD. Serum HDL cholesterol increased without an increase in LDL cholesterol in this study population, most of whom were taking cholesterol-lowering statins.

    Fall prevention with supplemental and active forms of vitamin D: a meta-analysis of randomised controlled trials. Bischoff-Ferrari HA, Dawson-Hughes B, Staehelin HB, Orav JE, Stuck AE, Theiler R, Wong JB, Egli A, Kiel DP, Henschkowski J. BMJ. 2009 Oct 1;339:b3692. doi: 10.1136/bmj.b3692. PMID: 19797342 doi: 10.1136/bmj.b3692 Conclusions Supplemental vitamin D in a dose of 700-1000 IU a day reduced the risk of falling among older individuals by 19% and to a similar degree as active forms of vitamin D. Doses of supplemental vitamin D of less than 700 IU or serum 25-hydroxyvitamin D concentrations of less than 60 nmol/l may not reduce the risk of falling among older individuals.

    Vitamin D supplementation improves neuromuscular function in older people who fall. Dhesi JK, Jackson SH, Bearne LM, Moniz C, Hurley MV, Swift CG, Allain TJ. Age Ageing. 2004 Nov;33(6):589-95. PMID: 15501836 doi:10.1093/ageing/afh20 9 CONCLUSIONS: vitamin D supplementation, in fallers with vitamin D insufficiency, has a significant beneficial effect on functional performance, reaction time and balance, but not muscle strength. This suggests that vitamin D supplementation improves neuromuscular or neuroprotective function, which may in part explain the mechanism whereby vitamin D reduces falls and fractures.

PMID: 19307517 Conclusion Nonvertebral fracture prevention with vitamin D is dose dependent, and a higher dose should reduce fractures by at least 20% for individuals aged 65 years or older.

    Estimation of the dietary requirement for vitamin D in free-living adults >=64 y of age. Cashman KD, Wallace JM, Horigan G, Hill TR, Barnes MS, Lucey AJ, Bonham MP, Taylor N, Duffy EM, Seamans K, Muldowney S, Fitzgerald AP, Flynn A, Strain JJ, Kiely M. Am J Clin Nutr. 2009 May;89(5):1366-74. Epub 2009 Mar 18. PMID: 19297462 doi:10.3945/ajcn.2008.27334 Conclusion: To ensure that the vitamin D requirement is met by the vast majority (>97.5%) of adults aged ≥64 y during winter, between 7.9 and 42.8 µg vitamin D/d is required, depending on summer sun exposure and the threshold of adequacy of 25(OH)D. .

    How much vitamin D3 do the elderly need? Viljakainen HT, Palssa A, Kärkkäinen M, Jakobsen J, Lamberg-Allardt C. J Am Coll Nutr. 2006 Oct;25(5):429-35. PMID: 17031013 Conclusions: A clear dose response was noted in S-25-OHD to different doses of vitamin D3. The recommended dietary intake of 15 µg is adequate to maintain the S-25-OHD concentration around 40-55 nmol/L during winter, but if the optimal S-25-OHD is higher than that even higher vitamin D intakes are needed. Interestingly, subjects with lower vitamin D status at baseline responded more efficiently to supplementation than those with more adequate status

    Effects of vitamin D and calcium supplementation on falls: a randomized controlled trial. Bischoff HA, Stähelin HB, Dick W, Akos R, Knecht M, Salis C, Nebiker M, Theiler R, Pfeifer M, Begerow B, Lew RA, Conzelmann M. J Bone Miner Res. 2003 Feb;18(2):343-51. PMID: 12568412 A single intervention with vitamin D plus calcium over a 3-month period reduced the risk of falling by 49% compared with calcium alone. Over this short-term intervention, recurrent fallers seem to benefit most by the treatment. The impact of vitamin D on falls might be explained by the observed improvement in musculoskeletal function.

JAMA. 2005 May 11;293(18):2257-64. Review. PMID: 15886381 Conclusions Oral vitamin D supplementation between 700 to 800 IU/d appears to reduce the risk of hip and any nonvertebral fractures in ambulatory or institutionalized elderly persons. An oral vitamin D dose of 400 IU/d is not sufficient for fracture prevention.

While this therapy appears to be safe, the potential for developing hypercalciuria needs to be examined in a large randomised controlled trial.
