Thorne Collagen Fit is a collagen peptide supplement formulated with the addition of nicotinamide riboside (NR), a precursor to NAD+, which is studied for its role in cellular energy metabolism and tissue repair. The collagen peptides themselves provide amino acids - particularly glycine, proline, and hydroxyproline - that are the structural building blocks of connective tissue, cartilage, and skin.
Mix one scoop into water or a cold beverage daily. Follow the packaging for timing guidance - some collagen peptide products are taken around exercise, while others are used at any consistent time of day. Take with a meal if you find it easier to maintain the habit that way.
This combination makes it a considered choice for people in regular physical training who want to support joint integrity alongside recovery. It may also suit those noticing early signs of joint discomfort tied to activity, or anyone looking to maintain skin structure as part of a broader nutrition strategy. It is not a protein supplement in the conventional sense - the amino acid profile is specific to connective tissue, not muscle protein synthesis - so it sits alongside, rather than replacing, a broader dietary protein intake.
Thorne is a brand with a strong clinical reputation and long-standing presence in practitioner-recommended supplement lines. Their manufacturing standards are consistently positioned at the higher end of the supplement industry. Collagen Fit reflects their approach of pairing a well-understood structural ingredient with a more targeted metabolic co-factor, rather than loading a formula with underdosed additions.

Sign inMost collagen supplements contain peptides alone. Collagen Fit also includes nicotinamide riboside, a precursor to NAD+ that is studied for its role in cellular energy metabolism. This makes it more relevant for people focused on recovery and physical performance, not just skin or joint structure.
Yes. Collagen peptides have a specific amino acid profile suited to connective tissue rather than muscle protein synthesis, so they do not duplicate a whey or plant protein supplement. Using both is common among athletes with high training loads.
Collagen-based supplements are generally studied over periods of several weeks to months. Joint and skin changes are gradual by nature — a consistent daily habit over at least eight to twelve weeks is typically the minimum meaningful timeframe.
Collagen peptides are animal-derived, so this product is not suitable for vegans or vegetarians. Check the packaging for the specific source if that detail matters to you.
Nicotinamide riboside is generally well tolerated, but if you are taking medications that affect NAD+ pathways or have a specific medical condition, it is worth checking with your GP or prescribing clinician before starting. Collagen peptides are not associated with common drug interactions.
Overall

Stir it into my coffee before the school run. Barely notice it's there taste-wise, which is exactly what I want from a supplement. Joints have been noticeably less stiff on my morning runs over the past couple of months.

Picked this up on a whim after my physio mentioned collagen timing around training. Wasn't expecting much straight away but after about two weeks I noticed my knees feeling less grindy after long runs. Still early days but the first impression is good. Mixes cleanly, no weird aftertaste. Will keep going.

I take this alongside a protein shake rather than instead of one — it's not a protein replacement, which I appreciated the product being honest about. My knee niggles during cycling sessions have eased up since starting this.

Works well and mixes cleanly into water. My main gripe is the container size — feels like you run out quite fast for the price. Would consider a larger format if they offered one.

Recommended by my physio after a shoulder injury. Been on it six weeks and recovery between sessions feels quicker. No taste, no clumping — does what it says.

Started this before half marathon training. Hip flexors and ankles were my weak points previously. Things feel more resilient now, though obviously hard to isolate one supplement. Good quality product either way.
