The Claim
In vitro, the combination of Garcinia kola and Newbouldia laevis extracts inhibits α-amylase activity more strongly than either extract alone, with an IC50 of 0.094 mg/mL for the combination, 0.730 mg/mL for Newbouldia laevis, and 0.250 mg/mL for Garcinia kola after four weeks of exposure.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When tested in a laboratory setting, a mixture of Garcinia kola and Newbouldia laevis extracts blocks the enzyme α-amylase more effectively than either extract by itself, requiring a lower concentration to achieve half-maximal inhibition after four weeks.
See the scientific wording
In vitro, the combination of Garcinia kola and Newbouldia laevis extracts exhibits enhanced inhibition of α-amylase activity compared to either extract alone, with an IC50 of 0.094 mg/mL for the combination versus 0.730 mg/mL for Newbouldia laevis and 0.250 mg/mL for Garcinia kola after four weeks.
Chemicals from two plants bind together to the starch-digesting enzyme in a way that blocks its active site and changes its shape, making it much harder for the enzyme to break down starch.
What the research says
1 studyWhen scientists mixed extracts from two plants — Garcinia kola and Newbouldia laevis — in a lab dish, they found that together they blocked a starch-digesting enzyme much better than either plant alone. This suggests the two plants might work better as a team.
