The short answer
Aloe gel has not been shown to cause added hypoglycemia with insulin aspart protamine in NovoLog Mix70/30. Oral gel studies with other diabetes drugs do not establish that combination risk.
What this answer covers
Oral Aloe vera gel; latex, whole leaf and topical gel differ. Medication evidence concerns the fixed70/30 premix.
- Supplement or preparation
- Aloe vera
- Medication ingredient
- insulin aspart protamine, human
The clinical trial used oral drugs
A small trial added aloe gel to glyburide and metformin, improving glucose measures and reporting no adverse effects in its abstract. It did not test this insulin premix.
Better glucose control is a different endpoint
Improved average glucose does not itself establish dangerously low glucose. The trial cannot quantify an added risk with insulin aspart protamine or separate that component from soluble aspart.
The aloe preparation matters
Gel is different from laxative latex or whole-leaf products. A topical product also differs from an oral supplement. The specific gel trial cannot establish safety across these exposures.
Keep the premix plan intact
Discuss the exact supplement and amount with the diabetes team and follow your glucose-monitoring and low-glucose treatment plan. Do not change the premix dose yourself. The product contains fixed proportions of intermediate-acting and rapid-acting insulin, so its components cannot be adjusted independently.
Evidence and practical considerations
Side effects & toxicity
Indirect aloe-gel efficacy evidence does not establish clinical hypoglycemia with the exact protamine-aspart component or fixed premix.
- Exact scope
- Oral Aloe vera gel; latex, whole leaf and topical gel differ. Medication evidence concerns the fixed70/30 premix. with Insulin aspart protamine human RxCUI352385 IN as part of NovoLog Mix70/30, SC only.
- Medication form and route
- subcutaneous insulin premix; oral supplement
What remains uncertain
- Combination label cannot isolate protamine component; no exact herb-event rate or universal adjustment.
Factors that may matter: Fixed component ratio; Meals; Preparation; Dose; Other glucose-active treatment.

Population: Adults prescribed the fixed insulin-aspart premix
Hypoglycemia can be severe; niacin can reduce glucose lowering. Fixed ratio does not permit independent basal/prandial adjustment. Dose within15minutes before meal start; type2 patients may also dose after meal start as labeled.
How this applies: Exact RxCUI352385 IN insulin aspart protamine, human, addressed as component of this labeled fixed combination.
Combination-product evidence cannot isolate the protamine component or represent pure soluble aspart, NPH or other premixes. No herb-specific event rate.

Aloe gel improved glucose measures with oral diabetes medicines; no adverse effects reported in the abstract.
How this applies: Indirect for insulin aspart protamine as part of NovoLog Mix70/30; original preparation, drug and endpoint retained.
Not insulin aspart protamine in this premix. Small trial and absence of reported adverse effects do not establish a hypoglycemia risk rate or cover latex/whole-leaf products.

Guidance distinguishes oral preparations and describes limited glucose-lowering research; latex can cause abdominal pain, cramps and diarrhea.
How this applies: Indirect for insulin aspart protamine as part of NovoLog Mix70/30; original preparation, drug and endpoint retained.
General guidance does not establish an exact insulin-premix interaction or equivalence of different aloe products.
