aSquared Nutrition Berberine with Ceylon Cinnamon Review

This product gives berberine at 1200 mg a day, twice the 600 mg that worked in studies. It also gives Ceylon cinnamon at 200 mg a day, above the 120 mg that helped in one trial. Berberine has strong human evidence for lowering blood sugar. Across 37 trials in 3,048 people with type 2 diabetes, it lowered fasting and long-term blood sugar without raising the risk of low blood sugar ^[1]. Another pooled analysis of 46 trials also found better insulin resistance and lower blood fats ^[2]. In 409 newly diagnosed adults, 12 weeks of berberine lowered long-term blood sugar more than placebo, but it caused more stomach upset ^[3]. Effects seemed weaker beyond 90 days or above 2 grams a day ^[4]. For cinnamon, a pooled analysis of 28 trials found lower fasting, after-meal and long-term blood sugar ^[5]. A trial of Ceylon cinnamon extract in 210 adults agreed ^[6]. Low doses of 120 to 360 mg of extract helped in 66 adults who were also taking meds ^[7]. Some cinnamon studies found no effect, so its evidence is less consistent than the evidence for berberine. The added fat-based absorption matrix has no study results given here. Animal and cell studies are never counted.

Berberine is the main ingredient, and most of the panel recommends or uses it, mainly for blood sugar, with some also citing cholesterol, sleep, cravings and heart health. Doses come up as 500 mg with meals, taken up to three times a day, and two panelists mention dihydroberberine or a better absorbed form. Taking it with food is the key advice, since one panelist warns that an empty stomach brought headaches, dizziness and low blood sugar, while two others stopped using it and another is skeptical of the evidence for supplements in general. Another cautions about combining it with other glucose lowering products and talking to a doctor first. Cinnamon, also a main ingredient here, is used by about half the panel in coffee, oats, smoothies, puddings and desserts to support blood sugar, with one panelist using Ceylon cinnamon and one warning that it is high in oxalate.

The review summary draws on other aSquared berberine products and on comparable berberine and cinnamon products, not readable reviews of this exact product, so it is set aside; no reviews were counted and the tier stands. Its reviews are set aside, so it is graded on its studies alone. Human studies support Berberine (52 of 63 human studies showed an improvement), but there are not yet enough reviews to confirm it (0).

Combine with: For blood sugar support, berberine pairs well with chromium picolinate, alpha-lipoic acid, and magnesium, which support insulin signaling and glucose uptake. Inositol (myo- and D-chiro) is a good addition for women with insulin resistance or PCOS. Soluble fiber such as psyllium or glucomannan can blunt post-meal glucose spikes and promote satiety if weight is also a goal. Omega-3 fish oil and vitamin D support metabolic and cardiovascular health. Take berberine with meals to limit GI upset. Consult a healthcare provider first if you take meds, because of additive glucose lowering and drug interactions, and avoid it during pregnancy or breastfeeding.
