On slowing time: multivitamins, acupuncture, and the art of ageing well

A major randomised, double-blind, placebo-controlled trial, recently published, has demonstrated that daily multivitamin supplementation may decelerate biological ageing, as assessed by epigenetic markers. Conducted by researchers at Columbia University and Brigham and Women’s Hospital, the study followed over 2,200 participants aged sixty and above for a period of two years, evaluating the long-term effects of daily micronutrient intake.

Epigenetic age — distinct from chronological age — was estimated via DNA methylation, a biomarker increasingly recognised for its accuracy in gauging biological ageing. The results revealed a marked slowing of this process among those receiving the multivitamin: on average, participants exhibited approximately two years less biological ageing when compared with their counterparts in the placebo group.

These findings lend weight to the hypothesis that subtle yet chronic micronutrient deficiencies may hasten the ageing process, even in the absence of overt deficiency diseases. Repletion through multivitamin use appears to mitigate this acceleration, particularly among individuals with marginal dietary intake. Encouragingly, no significant adverse effects were observed, suggesting the safety of prolonged supplementation.

The authors duly caution that replication in further trials is necessary. Multivitamins — like all supplements — are no substitute for a varied, balanced diet and a healthy lifestyle. Even so, the evidence is compelling, and may prompt clinical guideline committees to consider the role of randomised trials and mechanistic insights when deliberating whether to endorse multivitamin use as an adjunct to conventional preventative strategies in age-related disease.

What relevance might this have to acupuncture? Strikingly, the findings echo core tenets of Traditional Chinese Medicine, wherein premature ageing is understood as the consequence of Jing depletion — the vital essence stored in the Kidneys. Acupuncture, by stimulating specific points to nourish the Kidneys, strengthen the Spleen, and regulate the Liver, plays a direct role in preserving this essence, thereby fostering healthier, more gradual ageing.

Furthermore, acupuncture is known to modulate neuroendocrine function, improve sleep quality, attenuate oxidative stress, and promote metabolic equilibrium — mechanisms that align closely with the epigenetic shifts observed in the study. In this light, multivitamins and acupuncture may be regarded not as alternatives, but as complementary approaches: the former offering cellular nourishment, the latter mobilising the body’s innate capacity to sustain vitality over time.

What Winter Asks

By
Lately, I’ve found myself anticipating winter — not because it is here, but because its presence has begun to register. A shift in tone. A quiet deviation from the familiar. We are still within autumn, yes, but the pattern is clear: a cooling, a thinning of light, a withdrawal. Winter does not arrive with grandeur. It infiltrates. It operates in intervals — a guest that does not overstay, yet rearranges the room all the same. It brings with it not only the chill, but a quiet audit of our habits. Our homes, designed for air and openness, falter in the face of this visitor. We adjust. Coats reappear. Blankets are retrieved from high places. Improvisation becomes method: Havaianas with woollen socks. Soup, made not only to nourish but to ground. This is where hygge emerges — not as aesthetic, but as principle. The deliberate act of creating warmth within transience. A structured comfort, built from attentiveness. Outside, clouds obscure the light. Inside, a countermeasure: sof...

The Navel and the Whole

By
In the course of daily life, concepts such as knowledge, self-knowledge, and the practice of goodness ought never to be forgotten. Yet not only are they neglected — they are actively abandoned, especially when they stand at odds with the ambitions of humankind. And therein lies the blind spot of human pride: the self — the ever-contemplated navel. I see it manifest in the most absurd of circumstances, where there is no sincere interest in understanding the other. The affluent denigrate the poor; the poor resent the affluent. But where, I ask, is our shared humanity? Where is the recognition that the destiny of one is bound to the destiny of all? That recognition remains — dimmed, tucked away in some forgotten recess — awaiting the rekindling of light. When I welcome a homosexual patient, I see someone in search of that very light, navigating life in a conservative, restrictive city that offers little room to breathe. When I receive someone ensnared in substance use, I encou...
