Latest Update on Metformin


No wonder my IBS got better when I was on Metformin. I may try to start "Metformin Synergy" from Empower Pharmacy with Leucine and low dose sildenafil (yes, Viagra) to see if I do not lose muscle pump or get tired like I did with Metformin monotherapy 500 mg twice per day. I could use losing a few of my quarantine pounds also. These are not human studies but...

Hi Nelson,

I have tried this combination and found that I gained muscle and I believe your suspicions are correct, you will not lose your muscle pump or mass, as I did not. The muscle sensitizing effect on muscle seems to be profound in my case, subjectively speaking.

My pre-existing concerns of it's negative effects on attenuating the beneficial effects of exercise is still of concern.

Have you tried the combination of these three agents?

.... "at $4 a month," it's hard to argue with the economics, she noted.

Newer drugs that have shown benefit in cardiovascular outcomes trials include the SGLT-2 inhibitors empagliflozin (Jardiance, Boehringer Ingelheim) in EMPA-REG OUTCOME and canagliflozin (Invokana, Johnson & Johnson) in CANVAS, and the GLP-1 agonists liraglutide (Victoza, Novo Nordisk) in LEADER and semaglutide (Ozempic, Novo Nordisk) in SUSTAIN-6.

But these studies were mainly conducted in patients with high-risk type 2 diabetes who had a long duration of disease and already had cardiovascular disease (CVD) or a number of risk factors for it.

"So these data do not directly translate to 87% of our population," requiring first-line therapy for type 2 diabetes, Aroda argued.

She also pointed to safety, acknowledging, "We all know the potential for gastrointestinal disturbances with metformin and B12 deficiency," but this pales in comparison to the numerous safety warnings issued for newer drugs over the past few years, she said."

..."metformin does not address many of the core pathophysiologies of type 2 diabetes, she argued, and secondly, "you do not improve metabolic parameters as well as other [drugs] can." Although metformin lowers HbA1c, it is fairly neutral when it comes to any benefits on weight, blood pressure, and lipids, for example."


I'm a big fan of the evidence for semaglutide and have recently started taking it for personal researching. I may consider combining with canagliflozin once I get a feel for long-acting GLP-1. I will report back.
