What is
metformin XR?
Metformin is one of the most widely used prescription medicines for type 2 diabetes. The XR (extended-release) tablet releases the medicine slowly through the day, so most people take it once a day with the evening meal. Telean Rx offers it in its longevity program. Using metformin for healthy aging is off-label.
01
How does
metformin work?
Metformin lowers the amount of sugar the liver releases into the blood and helps the body respond better to insulin. That keeps blood sugar steadier. Researchers are studying it for aging because steadier blood sugar and insulin levels are linked to lower risk of several age-related diseases.
02
What does the research say
about metformin and aging?
Most of what is known comes from people with diabetes and from animal studies. Some studies of people with diabetes on metformin found lower rates of certain age-related diseases.
Why the extended-release
(XR) form?
The XR tablet releases metformin slowly, so you take it once a day instead of two or three times. Many people find it easier on the stomach than the immediate-release form. Swallow it whole with your evening meal. Do not crush, cut or chew it.
What are the side effects
of metformin?
The most common side effects are diarrhea, nausea and stomach upset. The XR form and taking it with food often make these milder. Over years, metformin can lower vitamin B12 levels.
In rare cases, metformin can cause lactic acidosis, a serious build-up of acid in the blood. The risk is higher with kidney problems, heavy drinking or severe illness. Get medical help right away for unusual muscle pain, trouble breathing, extreme tiredness or stomach pain with vomiting. Your provider may check your kidney function before you start.
Metformin vs sirolimus
for longevity
They work on different pathways. Metformin acts on blood sugar and insulin. Sirolimus acts on mTOR, a pathway tied to cell growth. Metformin has a much longer safety record because millions of people take it for diabetes. Your provider can help you decide whether either fits your goals.

Frequently asked questions
Do I need diabetes to take metformin?
No. Some providers prescribe it off-label for people without diabetes as part of a longevity plan. Your provider will decide if it fits your health.
Will metformin help me lose weight?
Some people lose a small amount of weight on metformin, but it is not a weight-loss drug. If weight loss is your main goal, ask about GLP-1 options.
When should I take metformin XR?
Most people take it once a day with the evening meal. Swallow it whole. Do not crush or chew it.
Can I drink alcohol on metformin?
Heavy drinking raises the risk of lactic acidosis. Keep alcohol light and ask your provider what is safe.
Does metformin affect vitamin B12?
Over years, metformin can lower vitamin B12 levels. Your provider may check your B12 and suggest a supplement if it runs low.
Can I take metformin with other longevity medicines?
Tell your provider about everything you take. Some longevity plans pair metformin with other medicines, and your provider will review them together.
Do I need a prescription, and how much does it cost?
Yes. A licensed Telean Rx provider can write one after a free online consultation if metformin is safe for you. Telean Rx is direct-pay with free shipping, so insurance is not required.
