'I'm a doctor and there are 3 anti-ageing supplements that actually work for longevity'

Dr Mark Hyman explained which three supplements are best for longevity.

These are NAD (Nicotinamide Adenine Dinucleotide), HTB Rejuvenate (Himalayan Tartary Buckwheat) and a Phyto Polyphenol blend.

He said: "One [supplement] that is really important is called NAD.

"It's an important compound that is part of your cellular metabolism. It helps to produce energy.

"When NAD levels are good, it turns on the sirtuins which then creates a whole series of events, it creates longevity. It sends out a massive DNA repair team."

The expert added it stops inflammation, which is a big factor in ageing.

NAD has anti-ageing benefits, according to studies published in the National Library of Medicine.

It states: "In numerous studies, supplementation with NMN has increased NAD+ biosynthesis, suppressed age-related adipose tissue inflammation, enhanced insulin secretion and insulin action, improved mitochondrial function, improved neuronal function in the brain, and more."

He also recommended HTB which has anti-inflammatory benefits.

Dr Hyman said: "As we age, some of our cells get older. They don't really die... but they're creating a whole inflammatory cascade and then they're causing other cells to become senescent zombie cells. [HTB] can help to kill that."

He explained the ageing of cells is a big part of the ageing process, so stopping this from happening as quickly can help with longevity.

The doctor added a Phyto Polyphenol blend is also worth taking.

In this blend, he said he would include catechins, resverarol, quercetin and curcumin.

Commenting on resverarol, the National Library of Medicine said: "Many studies reported that resveratrol possessed various bioactivities, such as antioxidant, anti-inflammatory, cardiovascular protection, anticancer, antidiabetes mellitus, antiobesity, neuroprotection, and antiaging effects.

"Resveratrol could be an effective and safe compound for the prevention and treatment of ageing and age-related diseases."
