01 - Nutrient deficiencies

You're running low on key nutrients

Most guys in the UK are running low on key nutrients like vitamin d, selenium, magnesium and zinc. 

Declining soil quality paired with the modern diet makes it difficult to get the amounts you need to function at your best. 

Newbeing covers all of these common nutrient gaps in one daily drink.

02 - Declining testosterone

Testosterone has fallen 54% in the past 50 years

Your testosterone naturally falls by around 1% a year from your 30s. What's more concerning is men's average testosterone levels have declined significantly since 1972. 

It shows up as less energy, less drive to train, a slower recovery and a sense that you're not quite as sharp as you were.

Newbeing contains 12mg of zinc, which contributes to the maintenance of normal testosterone levels, alongside vitamin D3 and magnesium, which contribute to normal muscle function.

03 - NAD+

Your body's cellular energy NAD+ levels decline

Your NAD+ levels decline 30% between the ages of 45 and 60. You can think of NAD+ like the battery in your cells, charging them with energy. 

The research is early, but it is thought that if you can increase your NAD+ levels, it will support the reduction of tiredness and fatigue. Newbeing contains the NAD+ precursor, Nicotinamide Riboside to help elevate your NAD+ blood levels.

04 - Sleep

Getting good sleep quality

You already know this. Having regular, good quality sleep is one of the core pillars of feeling energised and at your best. 

Newbeing contains 300mg of mangesium bisglycinate which is proven to reduce tiredeness and fatigue, and some believe it is can improve your sleep quality, though we are still waiting for robust evidence.

05 - The habit

The fix only works if you take it every day.

The problem with trying to solve this with individual supplements is you end up with a cupboard of tubs: vitamin D, magnesium, a multivitamin, maybe creatine. Within a few weeks, half of them are forgotten.

Newbeing is one scoop in water, once a day: a refreshing citrus drink with 5g of creatine plus 15 other active ingredients to support men's physical and mental performance.
