REJUVE BIO-X® NAD+ Collagen Formula: Your User Guide

Thank you for choosing REJUVE BIO-X® NAD+ Collagen Formula. This guide explains what is in each capsule, how to take it, and how to build it into a routine you can keep. If anything is unclear, please visit our contact page.

What is REJUVE BIO-X®?

REJUVE BIO-X® is a daily food supplement made exclusively for SellHealth UK®. It brings together an NAD+ precursor, marine collagen and two fat-soluble vitamins in one formula, so you can take a single product rather than several.

Each pack contains 60 capsules, which is a 30-day supply at 2 capsules a day.

What is in each daily serving (2 capsules)

  • Nicotinamide riboside (NR): 300 mg. A recognised NAD+ precursor — NR is a form of vitamin B3 and among the most studied compounds in longevity science.
  • Hydrolysed marine collagen type I: 1,000 mg. Collagen peptides broken down into smaller pieces. Type I is the form most often used in skin research.
  • Vitamin D3: 2,500 IU (62.5 µg). Vitamin D contributes to the normal function of the immune system, the maintenance of normal bones and the maintenance of normal muscle function.
  • Vitamin K2 (MK-7): 120 µg. Vitamin K contributes to the maintenance of normal bones and to normal blood clotting.
  • Piperine (95% black pepper extract): 10 mg. Commonly included in supplement formulas alongside other ingredients.

The capsule shells are plant-based (HPMC, no gelatine). Because the formula contains marine collagen from fish, REJUVE BIO-X® is not suitable for vegans or for anyone with a fish allergy.

How to take it

  • Serving: 2 capsules a day with water.
  • When: many customers find it easiest with breakfast or another meal, which also suits the fat-soluble vitamins D3 and K2.
  • Storage: keep the lid closed and store in a cool, dry place away from direct sunlight.
  • Do not exceed the recommended daily amount.

Getting the most from your routine

  • Be consistent. Take it at the same time each day so it becomes a habit.
  • Give it time. Collagen studies usually run for 8 to 12 weeks, so judge any supplement over a sensible period rather than a few days.
  • Check your other supplements. If you already take vitamin D, vitamin K, another NAD+ precursor or a collagen product, add up the totals and check them with your pharmacist.
  • Look after the basics. Sleep, a varied diet with enough protein, sun protection and regular activity matter far more than any single supplement.

Who should speak to a doctor first

Please speak to your GP or pharmacist before taking REJUVE BIO-X® if you:

  • take blood-thinning medication such as warfarin (vitamin K can affect how these medicines work)
  • take any other prescribed medication or have a medical condition
  • are pregnant or breastfeeding
  • are under 18

Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of young children.

Quality and testing

  • Independently tested by SGS
  • Manufactured under GMP standards
  • No added fillers, sugars, artificial colours or preservatives
  • Every ingredient amount is listed on the label

Can I take it with REJUVE® NMN?
Many customers take both. If you are combining products, check the total amounts of each ingredient and speak to your pharmacist if you are unsure.

Is it suitable for vegetarians?
No. The capsule shells are plant-based, but the collagen comes from fish.

How long does one pack last?
60 capsules at 2 a day is 30 days.
