insulin
6 interactions related to insulin
insulin + chromium
Chromium has been studied as an insulin sensitizer, and the NIH Office of Dietary Supplements cautions that taking it alongside insulin could increase the risk of low blood sugar. In practice the effect seen in clinical trials is modest and inconsistent, but because insulin is already a potent glucose-lowering drug, it is sensible to anticipate that adding chromium could nudge your blood sugar lower than your dose was set for.
leucine + carbohydrates
Leucine activates mTOR-driven muscle protein synthesis and stimulates insulin release. Taken with carbohydrate, the insulin response is larger than with carbohydrate alone, which helps suppress muscle protein breakdown and increase amino acid uptake. The combination supports the post-exercise anabolic response, though leucine works best as part of a complete protein source rather than on its own.
smoking + insulin
Smoking worsens insulin resistance through nicotine-driven catecholamine release, oxidative stress, and inflammation, and slows subcutaneous insulin absorption through vasoconstriction, so people with diabetes who smoke typically need more insulin to reach the same glucose control. Quitting improves insulin sensitivity within days to weeks, so insulin doses often need to come down to avoid hypoglycemia.
creatine + carbohydrates
Taking creatine together with carbohydrate raises insulin, which increases how much creatine skeletal muscle retains by stimulating the sodium-dependent creatine transporter. The effect mainly speeds up the loading phase; long-term muscle saturation is reached either way with daily consistency.
bcaa + carbohydrates
Taking branched-chain amino acids with carbohydrate around training produces a modest, additive boost to post-exercise muscle protein synthesis through the insulin response and leucine-driven mTOR signaling. The effect is real but small, and BCAAs lack the other essential amino acids needed to fully build muscle, so a complete protein source with carbohydrate is the better default.
alcohol + insulin
Alcohol suppresses the liver's production of new glucose (gluconeogenesis), removing a key safety net against low blood sugar, while insulin lowers glucose directly. Combined, they can cause severe, prolonged, and delayed hypoglycemia, especially when drinking on an empty stomach or in the evening.
