Ageing is a biological process, but the rate at which it affects how you look and feel is not entirely fixed. The science of longevity has identified specific cellular mechanisms that drive many of the changes associated with getting older, and a growing body of research points to natural compounds that can support those mechanisms. Our anti aging supplements are built around that science, using 100% natural, vegan-friendly ingredients to support the way your body ages from the inside out
At the cellular level, ageing is closely tied to the decline of NAD+ (nicotinamide adenine dinucleotide), a molecule essential for energy production, DNA repair, and hundreds of metabolic reactions. NAD+ levels fall by roughly half between the ages of 40 and 60. Replenishing them through precursors like NMN and NR is one of the most researched approaches in modern longevity science.
Alongside NAD+ support, our range includes compounds targeting oxidative stress, cellular senescence, and autophagy (the body's natural process of clearing damaged cells). Together, these pathways represent the most evidence-supported routes to healthy, graceful ageing.
NMN Capsules with Astaxanthin (99% Pure) and NR Capsules with Astaxanthin are the core of our NAD+ pathway support. Both NMN and NR are direct precursors to NAD+, meaning your body converts them into active NAD+ after absorption. We pair both with astaxanthin, one of the most potent natural antioxidants known, to provide cellular protection alongside the NAD+ boost.
Spermidine Capsules with Astaxanthin support autophagy, the cellular recycling process that declines with age. Spermidine has attracted significant research interest for its role in promoting longevity pathways at the cellular level.
Altai Shilajit Resin and Himalayan Shilajit Capsules deliver fulvic acid and a broad spectrum of trace minerals in their most bioavailable form. Shilajit has been used in traditional medicine for centuries and is now supported by modern research for its role in mitochondrial function and cellular energy.
Berberine with Resveratrol combines two compounds with well-documented effects on metabolic health and sirtuin activation. Resveratrol in particular has been widely studied for its relationship with the longevity genes known as sirtuins.
Liposomal Chlorophyll Liquid Drops and Vitamin C Natural Extracts round out the range with powerful antioxidant and detoxification support.
Every supplement in the Feel Supreme range is 100% natural, vegan friendly, and lab tested for purity and potency. We have been manufacturing natural supplements for over 10 years and are trusted by more than 400 independent retailers across the UK. No artificial additives, no fillers, no compromises on ingredient quality. Just clean, effective formulations made in the UK.
The research on compounds like NMN, NR, resveratrol, and spermidine is genuinely promising. Studies suggest they can support NAD+ levels, reduce oxidative stress, and activate longevity-associated pathways. That said, supplements work alongside a healthy lifestyle, not instead of one. At Feel Supreme, every product is built around compounds with meaningful research support, not marketing trends.
Most people notice changes in energy and general vitality within 4 to 6 weeks of consistent use. Skin, hair, and physical resilience tend to show more visible improvements after 8 to 12 weeks. Consistency is key, so give it at least two months and pay attention to how you feel across energy, recovery, skin, and mood.
It depends on what you are trying to support. For NAD+ replenishment, one of the most researched areas in longevity science, NMN and NR capsules are the strongest starting point. For broader cellular support, combining an NAD+ precursor with spermidine (which supports autophagy) or resveratrol (which activates sirtuin pathways) covers multiple ageing mechanisms. If you are new to this area, starting with NMN or NR and building from there is a practical approach.
Yes, the natural compounds used in quality anti-aging supplements are generally considered safe for daily long-term use. Ingredients like NMN, NR, spermidine, and resveratrol have been used in human studies at consistent daily doses without significant adverse effects. Daily consistency also matters because these compounds support processes your body is constantly drawing on. All Feel Supreme products are 100% natural, vegan friendly, free from fillers, and lab tested for purity. If you take medication or have a health condition, check with your GP before starting any new supplement.
