How to take Keeper Complete Longevity

Your guide to optimal introduction & long-term use

Week 1: Starter phase

Dose
  • ¼ scoop daily.
When to take
  • With breakfast or your first meal.
What to expect
  • Subtle increase in energy and focus.
  • Your body is beginning to produce more NAD⁺.
  • Minimal to no side effects at this dose.
  • As your body adjusts to Complete Longevity, some people experience mild digestive sensitivity in the early stages. This is completely normal and typically settles within the first few days of use. Taking with food and staying well hydrated significantly reduces the likelihood of any discomfort.
Tips
  • Mix one scoop into 250ml of water or your beverage of choice and take daily, preferably in the morning with your first meal.
  • For optimal absorption, take alongside a meal containing healthy fats and maintain good hydration throughout the day to support cellular function.

Week 2: Build phase

DOSE
  • ½ scoop daily.
When to take
  • With breakfast or first meal.
What to expect
  • More noticeable energy throughout the day. 
  • Improved mental focus and clarity. 
  • If you experienced any mild digestive sensitivity in Week 1, it should be settling by now. 
  • You are now getting 250mg NMN, a moderate therapeutic dose.
Tips
  • If you experienced no issues in Week 1 you can confidently move to this dose. 
  • Continue taking with food and plenty of water.

Week 3: Progressive phase

DOSE
  • ¾ scoop daily.
When to take
  • With breakfast or first meal.
What to expect
  • Increase in energy and mental focus. 
  • Better physical resilience and stamina. 
  • You are now getting 375mg NMN.
Tips
  • Consider splitting the dose if you prefer, half scoop at breakfast and quarter scoop at lunch. This can provide more sustained energy throughout the day. 
  • Continue your hydration practices.

Week 4+: Full therapeutic dose

DOSE
  • 1 full scoop daily.
When to take
  • Full scoop with breakfast (most popular), or split dose with half scoop at breakfast and half scoop at lunch for sustained energy throughout the day.
What to expect
  • Full longevity and cellular support benefits. 
  • Optimal NAD⁺ production (500mg NMN and 150mg NR). 
  • Peak mitochondrial function support. 
  • Maximum antioxidant protection. 
  • Enhanced cellular renewal and autophagy activation supporting healthy ageing at the cellular level.
Long-term benefits may include
  • Sustained cellular energy and vitality throughout the day. 
  • Improved cognitive function, mental clarity, and cognitive resilience. 
  • Support for healthy ageing at the cellular level.

When will I start feeling results?

When will I start feeling results?
  • Most users notice improvements in energy, vitality, and mental clarity within 2 to 4 weeks of consistent daily use. Deeper benefits including enhanced cognitive resilience, sustained cellular energy, and support for healthy ageing at the cellular level typically build over 8 to 12 weeks. Results vary by individual.

Why start gradually?

Complete Longevity is a high-potency, science-backed formula containing 18 active ingredients designed to support cellular energy, longevity, and healthy ageing. While these ingredients are safe and well researched, the formula contains therapeutic doses of NAD⁺ precursors (500mg NMN + 150mg NR) and other powerful compounds that some people need to introduce gradually.

Starting gradually will:

  • Minimise digestive discomfort during the adjustment period
  • Allow your body to adapt to NAD⁺ boosting compounds
  • Help you identify your optimal dosing schedule
  • Maximise the longevity benefits while minimising side effects

You may skip directly to full dose if you:

  • Already take NMN or NR regularly at similar doses
  • Have used Complete Longevity before without issues
  • Tolerate high-dose supplements well
  • Are experienced with longevity stacks
