Sarcopenia is the medical term for age-related muscle loss. After 50, your body breaks down muscle faster than it can rebuild it - leading to reduced strength, increased fall risk, and loss of independence over time. Kept is specifically formulated to target this process.

At 3g per day, creatine has a very strong safety record across decades of clinical research. It has been studied in adults over 55 with no adverse effects on kidney function in any published trial. The EFSA reviewed the evidence and authorised a specific health claim at this exact dose. If you have a pre-existing kidney condition, speak to your GP before starting any new supplement.

The NHS doesn't prescribe supplements. Not ours. Not anyone's. That's a policy position about how supplements are classified, not a judgement on whether they work. Absence of prescription is not absence of evidence.

Protein helps build muscle. It doesn't slow the breakdown that accelerates with age. HMB does. They're two separate processes. Protein supports muscle building. HMB directly targets the breakdown. Kept contains HMB at the clinical dose shown to significantly reduce that breakdown, alongside nutrients that strengthen muscles and bones.

Kept contains 3,000 IU of vitamin D. The recommended upper safety limit is 4,000 IU per day - so if taking both keeps you under that, there's no need to change anything.

That said, Vitamin D on its own is only doing half the job. Without K2 to direct it and magnesium to activate it, much of what you take goes unused. Kept isn't a collection of random vitamins - it's a complete system where every ingredient makes the others more effective.

If you take regular medication, we'd always recommend mentioning any new supplement to your GP or pharmacist before starting.

Pay attention to the small things - they're easy to miss. Coming down the stairs in the morning without that first-thing hobble. Getting up off the floor in one go. DOMs that fade quicker. The afternoon dip not biting as hard. Most people start to notice these within the first few months. But part of what Kept does is invisible by design - muscle preservation is the absence of loss, not a feeling. That's why the clinical trials measured outcomes at 3 and 12 months using strength tests and body composition scans, not how anyone felt.

Kept stirs into juice, porridge, yoghurt, hot chocolate, Horlicks, or any hot drink. The formula was designed to be no faff - it disappears into whatever you already have each morning.

While Kept is unflavoured, the tannins in some teas can occasionally interfere with how the powder dissolves - if that's the case, herbal teas tend to work better.
