Customers generally view NOW Magnesium Glycinate with BioPerine capsules very positively, with 93% of its approximately 15176 ratings across various stores being 4 or 5 stars. Buyers frequently praise its effectiveness for several health benefits and its gentle nature. **What it did for them** Many customers report significant improvements in sleep and relaxation. Reviewers describe it as an "Excellent sleep aids!!" that helps them "sleep like a baby" and "stay sleeping over night." Some find it helps keep the mind from racing and "Helps with anxiety." Beyond sleep, many users experience relief from muscle issues, with one noting it is "Really helping with my leg cramps." Others use it for muscle recovery after training or for joint muscle recovery after hard sessions. Some buyers report an overall improvement in health, with one stating their "overall health is 100% better." It's also credited with supporting a calmer nervous system, increasing energy and focus, and contributing to overall wellness. A few users mention it helps manage symptoms linked to conditions such as PCOS. The addition of BioPerine black pepper extract is often noted as making a noticeable difference compared to plain magnesium glycinate, with some buyers saying it enhances absorption. Users also appreciate waking up refreshed and without feeling groggy. **Complaints** While feedback is overwhelmingly positive, some critical points emerge. The primary concerns revolve around inactive ingredients; one reviewer objects to microcrystalline cellulose, which they say caused bloating, and silicon dioxide, expressing worry about its long-term effect on intestinal lining and gut bacteria. This reviewer wished they had checked the ingredients before buying. Another significant caution is that BioPerine, which is piperine, can interfere with the metabolism of certain medications processed by the liver enzyme CYP3A4, prompting advice for people on medication to consult a doctor first. A few customers express disappointment about the lack of a Certificate of Analysis (COA) for specific product lots, stating, "Disappointed there is no COA available." A very small number of users found the product ineffective for sleep, with one stating it "Does not put me to sleep." **Taste, smell, pill size, form** The capsules are consistently described as small and easy to swallow. Many reviewers highlight the product's gentleness on the stomach, reporting no burping, heartburn, bloating, or weird aftertaste, especially when taken with a light snack. Unlike some other forms of magnesium, customers note there is no laxative effect. The product is confirmed to be magnesium bisglycinate from Albion Minerals, which is praised as a top-tier, chelated ingredient form that is well-absorbed and gentle. **Value for money** Customers frequently praise the product's affordability, with comments like "Best price i could find" and "Outstanding product and price." Many consider NOW a "Reliable Brand" that offers "quality ingredients" and the amounts listed. The brand's trustworthiness for quality ingredients at a good price is a recurring theme. Packaging is described as reliable, the bottle size as generous, and shipping as fast. Many buyers express their intent to repurchase the product. **Who it seems to suit and who it did not** This magnesium glycinate product appears well-suited for individuals seeking support for sleep, relaxation, and muscle recovery, including relief from leg cramps and post-training soreness. It is also favored by those looking for a magnesium supplement that is gentle on the stomach and does not cause digestive upset. However, it may not be suitable for those with sensitivities to inactive ingredients like microcrystalline cellulose or silicon dioxide. Individuals taking medications, particularly those processed by the liver enzyme CYP3A4, should exercise caution and consult a healthcare professional due to the BioPerine content. A very small minority of users did not find it effective for sleep.
