      Sleep supplements at Feel Supreme

      Feel Supreme brings together our sleep supplements in one place - the products people like to keep in their evening wind-down routine. You will find ashwagandha, 5-HTP and reishi alongside our CBD oils and CBG spray. If you are shopping for sleep supplements in the UK, use the range and the honest guide below to choose what suits you.

      Sleep supplements: what to know

      It is worth being straight about this category. Food supplements cannot legally be sold with claims that they improve your sleep, increase deep sleep or treat insomnia, so it is wise to be cautious of any product that promises those things. In the UK, melatonin - the ingredient with the clearest role in sleep - is a prescription-only medicine, not a food supplement, so you will not find it here or in other supplement ranges.

      What actually moves the needle most for sleep is your routine: a consistent bed and wake time, a cool, dark room, and winding down away from screens, caffeine and alcohol in the evening. Supplements are something people add around that routine, not a replacement for it. If you regularly struggle to sleep, it is worth speaking to your GP, as poor sleep can have underlying causes worth checking.

      Why choose Feel Supreme

      • Evening-routine favourites. Ashwagandha, 5-HTP and reishi - three of the botanicals people most often add to a wind-down routine.
      • CBD and CBG options. Full-spectrum CBD oils and a THC-free CBG nano spray, for those who prefer cannabinoid wellness products.
      • A choice of formats. Capsules, liquid extracts, oils and a spray - pick what fits your evening.
      • Vegan-friendly options, made in the UK. Ordering, support and delivery handled here.

      Best sleep supplements UK: how to choose

      When people look for the best sleep supplements in the UK, the right choice comes down to preference:

      • Botanicals. Ashwagandha and reishi are traditional botanicals many people take in the evening; 5-HTP is derived from Griffonia simplicifolia.
      • CBD or CBG. If you already use cannabinoid products, the CBD oils and CBG spray are here too - see the CBD range for full details.
      • Format and timing. Choose a format you will use consistently, and take it as part of an evening wind-down rather than expecting an instant effect.
      • Your routine first. Supplements work best alongside good sleep habits, a balanced diet and a regular schedule.

      Supplements and deep sleep

      Searches for supplements to increase deep sleep are common, so to be clear: no food supplement can be sold with a claim that it increases deep sleep. Deep (slow-wave) sleep is largely driven by your sleep pressure and routine - a consistent schedule, daylight in the morning, exercise, and limiting late caffeine and alcohol tend to matter far more than any supplement. If deep or restful sleep is a persistent problem, a GP is the right place to start.

      Sleep supplements FAQ

      What are sleep supplements?

      "Sleep supplements" is the popular name for products people add to an evening wind-down routine. At Feel Supreme the range includes ashwagandha, 5-HTP, reishi, CBD oils and CBG spray. They are food supplements, not medicines.

      Do sleep supplements work?

      Be cautious of any supplement that claims to improve your sleep - food supplements cannot legally make that claim. The single biggest factors for sleep are your habits: a consistent schedule, a cool dark room, and limiting screens, caffeine and alcohol in the evening. Supplements are something people add around a good routine, not a fix on their own.

      Can supplements increase deep sleep?

      No food supplement can be sold with a claim that it increases deep sleep. Deep sleep is mostly driven by your sleep routine and pressure - a regular schedule, morning daylight, exercise and limiting late caffeine and alcohol. If restful sleep is a persistent issue, speak to your GP.

      What is in the sleep range?

      Ashwagandha (a traditional botanical), 5-HTP (from Griffonia simplicifolia), reishi (a functional mushroom), full-spectrum CBD oils and a THC-free CBG nano spray. They are food supplements - see each product page for the ingredients and how to take them.

      Is CBD a sleep supplement?

      CBD is a food supplement, not a medicine, and it cannot be sold with sleep or health claims. Our CBD oils are full-spectrum (trace THC below the 0.2% legal limit) and the CBG spray is THC-free. If you already use cannabinoid products in the evening, they are part of this range - see the CBD collection for full detail.

      When and how do I take them?

      Each product has its own daily dosing on the label. Many people take evening-routine supplements in the hour or two before bed, but always follow the instructions on the individual product.

      Are they safe?

      Food supplements are generally well tolerated when taken as directed, but they are not a substitute for a varied diet or for good sleep habits. Do not exceed the recommended daily intake. If you are pregnant, breastfeeding, taking medication or have a medical condition - or if poor sleep persists - speak to your GP or pharmacist.

      Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily intake. CBD and CBG products are food supplements and are not medicines. If you are pregnant, breastfeeding, taking medication or have a medical condition, consult your doctor before use. Keep out of reach of children.
