Blood sugar management has become a growing concern not only for people living with diabetes but also for those looking to prevent insulin resistance, metabolic disorders, and energy crashes. In a recent Instagram video, UK-based physician Dr Kunal Sood discussed several supplements that may help support healthier blood sugar levels. He emphasised an important caveat, stating: “Blood sugar often improves when glucose enters the bloodstream more gradually, and insulin signalling becomes more efficient. These are supportive tools, not replacements for evidence-based diabetes management. Discuss with your doctor before starting any supplement.”

Among the supplements highlighted was berberine, which Dr Sood said may help improve insulin sensitivity. According to him, “Berberine may improve insulin sensitivity through AMPK-related pathways involved in glucose uptake, fat metabolism, and liver glucose production. Studies suggest improvements in fasting glucose, HbA1c, and insulin resistance markers.”
He also discussed psyllium husk, noting that “Psyllium forms a gel in the gut that slows gastric emptying and carbohydrate absorption. This can reduce post-meal glucose spikes and improve glycemic control, particularly in type 2 diabetes.” Magnesium was another supplement on his list, with Dr Sood explaining, “Magnesium is involved in insulin signaling and glucose metabolism. Low magnesium is linked to insulin resistance, and supplementation may improve fasting glucose and HOMA-IR when deficiency or low intake is present.”
Apple cider vinegar and cinnamon were also mentioned for their potential role in blood sugar regulation. Dr Sood stated, “Acetic acid may slow starch digestion and gastric emptying, helping reduce post-meal glucose excursions. Benefits appear most noticeable when paired with higher-carbohydrate meals.” Speaking about cinnamon, he noted, “Cinnamon contains compounds that may influence insulin signalling and glucose transport. Some studies show modest improvements in fasting glucose, HbA1c, and insulin resistance markers, although results remain mixed.”

What science says about popular blood sugar supplements
Ashlesha Joshi, Fitness Dietician and Nutritionist at Tone 30 Pilates, tells indianexpress.com, “Berberine and psyllium husk currently have some of the strongest evidence among commonly discussed supplements for blood sugar management. Berberine has been shown in multiple studies to improve insulin sensitivity and lower fasting blood glucose levels, while psyllium husk can help reduce post-meal glucose spikes by slowing carbohydrate absorption.”

She continues, “Magnesium may be beneficial, particularly in deficient individuals, as magnesium plays a key role in glucose metabolism and insulin function. Cinnamon and apple cider vinegar have shown promising but more variable results, with benefits appearing modest and often dependent on dosage, formulation, and individual metabolic health. It is important to note that supplements can support blood sugar control, but they are not a substitute for evidence-based medical care or dietary management.”
