| Substance | Interaction | What happens |
|---|---|---|
| CLA | Conflict | CLA (specifically the t10,c12 isomer in standard 50:50 supplements) has documented potential to reduce insulin sensitivity, while chromium is taken... |
| Berberine | Caution | Both lower blood glucose through different mechanisms. Combined use may cause excessive blood sugar reduction, especially in non-diabetics. details → |
| Berberine HCl | Caution | Both lower blood glucose through different mechanisms. Combined use may cause excessive blood sugar reduction, especially in non-diabetics. details → |
| Canagliflozin | Caution | Canagliflozin lowers blood glucose through SGLT2 inhibition and chromium improves insulin sensitivity. The combination is usually well tolerated... |
| Dapagliflozin | Caution | Dapagliflozin reduces blood glucose by promoting urinary glucose excretion, and chromium improves insulin sensitivity. On dapagliflozin alone the... |
| Dulaglutide | Caution | Chromium supplements are used for glucose metabolism, but clinical effects are inconsistent. Adding high-dose glucose-targeted chromium to... |
| Empagliflozin | Caution | Empagliflozin lowers blood glucose by causing urinary glucose excretion. Chromium independently improves insulin sensitivity. Used together the... |
| Fenugreek | Caution | Fenugreek and chromium are both commonly stacked for blood sugar and metabolic support, and each independently lowers fasting and postprandial... details → |
| Glimepiride | Caution | Chromium improves insulin sensitivity, while glimepiride forces pancreatic insulin release. Combined, the additive effect on blood glucose can... details → |
| Glipizide | Caution | Chromium supplementation can lower fasting glucose and HbA1c in type 2 diabetes by improving insulin signaling. Stacked on top of a sulfonylurea... details → |
| Glyburide | Caution | Chromium and glyburide both lower blood glucose by different mechanisms. Glyburide is the longest-acting sulfonylurea on the US market and already... details → |
| Insulin Aspart | Caution | Chromium may modestly improve insulin sensitivity in some people with diabetes or insulin resistance. Because insulin aspart is rapid-acting... |
| Insulin Glargine | Caution | Chromium may modestly improve insulin sensitivity in some people with diabetes or insulin resistance. Because insulin glargine provides basal... |
| Insulin Lispro | Caution | Chromium may modestly improve insulin sensitivity in some people with diabetes or insulin resistance. Because insulin lispro is rapid-acting... |
| Linagliptin | Caution | Linagliptin is a DPP-4 inhibitor that lowers blood glucose by prolonging endogenous GLP-1 activity. Chromium improves insulin sensitivity. On... |
| Liraglutide | Caution | Chromium supplements are used for glucose metabolism, but clinical effects are inconsistent. Adding high-dose glucose-targeted chromium to... |
| Metformin | Caution | Chromium supplementation enhances insulin sensitivity and may improve glucose metabolism. When combined with metformin, the additive... details → |
| Pramlintide | Caution | Chromium may modestly improve insulin sensitivity in some people with diabetes or insulin resistance. Pramlintide is used with mealtime insulin and... |
| Semaglutide | Caution | Chromium supplements are used for glucose metabolism, but clinical effects are inconsistent. Adding high-dose glucose-targeted chromium to... |
| Sitagliptin | Caution | Sitagliptin is a DPP-4 inhibitor that lowers blood glucose by prolonging endogenous GLP-1 activity. Chromium improves insulin sensitivity. The... |
| Tirzepatide | Caution | Chromium may enhance insulin signaling and glucose metabolism, adding to tirzepatide's glucose-lowering effect. |
| Vanadium | Caution | Vanadium and chromium both have insulin-sensitizing, glucose-lowering activity, so combining them can produce additive reductions in blood glucose... |
| Levothyroxine | Timing Sensitive | Chromium supplements, particularly chromium picolinate, have been shown in a small human absorption study to reduce levothyroxine exposure. This can... details → |
| Alpha-Lipoic Acid | Synergy | Combining chromium with alpha-lipoic acid may improve insulin sensitivity and cellular glucose uptake more than either taken alone. |
| Inositol | Synergy | Myo-inositol and chromium each support insulin sensitivity through different routes, so combining them may give additive benefit on fasting insulin... |
| Magnesium Glycinate | Synergy | Chromium and magnesium each support insulin signaling, so adequate status of both is associated with better insulin sensitivity than low status of... |
| Vitamin B3 | Synergy | Combining niacin with chromium has been studied as a way to improve glucose handling. Controlled work in older adults found that niacin-bound or... |
| Vitamin B7 | Synergy | Chromium picolinate combined with biotin (vitamin B7) has improved fasting glucose and glycemic markers more than chromium alone in studies of... details → |
| Vitamin C | Synergy | Vitamin C enhances chromium absorption by reducing Cr3+ in the gut, making it more bioavailable. details → |
| Vitamin C Liposomal | Synergy | Vitamin C Liposomal enhances chromium absorption by reducing Cr3+ in the gut, making it more bioavailable. |

Common chromium questions.
Quick answers drawn from the table above.
What interacts with Chromium?
In the NutriStack database, Chromium has 30 documented interactions with other supplements and medications. The most notable include CLA, Berberine, Berberine HCl, Canagliflozin, and Dapagliflozin.
What should you not take with Chromium?
Chromium is flagged against 1 substance in the database, including CLA. Review these with a clinician before combining, especially alongside prescription medications.
What works well with Chromium?
Chromium pairs synergistically with Alpha-Lipoic Acid, Inositol, Magnesium Glycinate, Vitamin B3, and Vitamin B7 in the NutriStack database. Synergy still depends on dose and timing; open any pair for the detail.
Can you take Chromium with CLA?
NutriStack classifies the Chromium and CLA pairing as conflict: CLA (specifically the t10,c12 isomer in standard 50:50 supplements) has documented potential to reduce insulin sensitivity, while chromium is taken to improve it.... If you are using chromium to support glucose control, be cautious stacking it with high-dose mixed CLA (3 to 6 g/day). They can be taken in the same...
