Night Time Metabolism Complex (90 Capsules)

Nutrivolv Night Time Metabolism Complex is a pre-sleep supplement delivering six active ingredients per three-capsule serving: Glycine 1000mg, L-Theanine 200mg, Lemon Balm Extract equivalent to 1000mg, Magnesium Bisglycinate 200mg, Saffron Extract 15mg, and BioPerine 5mg. The formula is designed to support relaxation and sleep quality while also supporting overnight fat metabolism and appetite regulation. It is stimulant-free, which makes it suitable for evening use without disrupting sleep.

This product is well suited to adults who want to support their metabolic health and body composition goals around the clock, including during overnight hours when the body undertakes repair and recovery processes. It is also a practical option for people who struggle with sleep quality, evening appetite or cravings, or restlessness at night. The stimulant-free, relaxation-focused formula makes it particularly relevant for those who find caffeinated metabolism supplements unsuitable in the evening. It is not suitable for children, pregnant women, or breastfeeding women.

Each three-capsule serving contains six active ingredients. Glycine at 1000mg is an amino acid that supports sleep quality, particularly the restorative slow-wave sleep phase, and plays a role in glucose regulation and muscle maintenance overnight. L-Theanine at 200mg promotes calm focus and relaxation without sedation, supporting the transition into restful sleep. Lemon Balm Extract at a 1000mg equivalent is a traditional herb associated with reducing anxiety and promoting relaxation and sleep quality. Magnesium Bisglycinate at 200mg (40% of the NRV) is a highly bioavailable form of magnesium that supports muscle relaxation, nervous system function, and sleep. Saffron Extract at 15mg (5% Safranal) is associated with mood support and appetite regulation, which is relevant for managing evening cravings. BioPerine at 5mg (piperine from black pepper extract) enhances the absorption of the other ingredients.

Take three capsules 30 to 60 minutes before bed and swallow with water. The label confirms this timing. Taking the capsules before bed allows the relaxation and sleep-supporting ingredients, particularly glycine, L-Theanine, lemon balm, and magnesium, to reach peak effect as you prepare for sleep. Because the formula is completely stimulant-free, there is no risk of the capsules disrupting your sleep when taken at the recommended time.

The overnight metabolic support in this formula works through several pathways rather than through stimulant-driven thermogenesis. Glycine supports glucose regulation and muscle protein synthesis during sleep, both of which contribute to body composition over time. Magnesium bisglycinate supports insulin sensitivity and energy metabolism. Saffron extract is associated with appetite and craving regulation, which may reduce late-night eating. Improved sleep quality itself is a significant factor in metabolic health, as poor sleep is linked to increased appetite hormones, reduced insulin sensitivity, and greater fat storage. This product supports overnight metabolism indirectly through sleep quality and appetite regulation rather than directly burning fat.

Magnesium bisglycinate is a chelated form of magnesium bound to the amino acid glycine, which gives it significantly better absorption than magnesium oxide and is much gentler on the digestive system. Magnesium oxide, the most commonly used form in lower-cost supplements, has a lower absorption rate and is more likely to cause loose stools or digestive discomfort, particularly when taken at night. Using bisglycinate in a night-time formula is a deliberate choice that prioritises both effectiveness and tolerability, as digestive discomfort before bed would counteract the sleep-support goals of the product.

The ingredients in this formula are generally well tolerated in healthy adults at the doses included. Glycine, L-Theanine, lemon balm, and magnesium bisglycinate all have strong safety profiles at these levels. Saffron at 15mg is a moderate dose and is within the range used safely in human studies. The label advises that pregnant and breastfeeding women seek medical advice before use, and that the product is unsuitable for children. If you take prescribed medication, particularly for sleep, anxiety, or blood pressure, speak to your GP before use as some ingredients, particularly lemon balm and magnesium, can have additive effects with certain medications.

For most healthy adults, this product can be taken alongside other supplements. If you already take a separate magnesium supplement, account for your total daily magnesium intake across all products. The BioPerine in this formula enhances absorption of co-administered compounds, so be aware that it may also affect the absorption of other supplements or medications taken at the same time. This product pairs well with a daytime metabolic support supplement such as MetaBurn GLP Complex, which targets carbohydrate processing and blood sugar balance during waking hours.

Yes, this product is completely stimulant-free. There is no caffeine or other stimulant in the formula. The relaxation and sleep-support ingredients, particularly L-Theanine, lemon balm, and glycine, support the natural wind-down process before sleep rather than inducing sedation. Most people find the formula promotes a calm, relaxed state that makes falling asleep easier, but it does not cause the heavy sedative effect associated with antihistamine-based sleep aids. It is not recommended to drive or operate machinery after taking this supplement until you know how it affects you.

Each pack contains 90 capsules. At the recommended dose of three capsules per night, that is a 30-day supply. At £11.95 per pack, that works out at approximately 40p per day. The product is UK-made, vegan-friendly, and free from dairy, fish, soy, gluten, and GMO.
