Fish Oil for Aging Muscles: What 14 Studies Actually Show
Fish oil is being pitched as armor for aging muscles, but what does the evidence actually say? A 2026 umbrella review pooled seven RCTs and seven meta-analyses in adults 55 and older. It found modest but measurable strength gains, with the clearest signal for lower-body strength and function. Grip strength, walking speed, and upper-body strength were far less certain, and heavy overlap among the studies means the evidence is shakier than it looks. Here is what it means, who it may help, and who should check with a doctor first.
Tongkat Ali: 400 mg for 5 Weeks Lifted Testosterone and Grip Strength
Tongkat Ali is one of the most-searched testosterone boosters on the internet, and a small pilot study gives it some real human data. Twenty-five active adults aged 57-72 took 400 mg of extract daily for 5 weeks, and both total and free testosterone rose, along with handgrip strength. Women's free testosterone climbed too, apparently because SHBG dropped. But there was no placebo group, so this is promising rather than proof. Here is what the study found, what it can't tell you, and how to approach it sensibly.
