Could a tooth supplement increase your workout stamina? The results are shocking
· New York PostThousands of Amazon shoppers bought a popular supplement for their oral health. They didn’t expect to notice benefits at the gym.
But that’s what happened when some shoppers started taking Strong Jaw Tooth Restore, a trending formula that combines vitamin D3, calcium, hydroxyapatite and essential minerals to help support oral health.
The supplement is currently 26% off ahead of Amazon Prime Day, which kicks off Oct. 6, though many deals are already live. But the discounted price isn’t the only thing catching shoppers’ attention. After starting the supplement, some users say they noticed unexpected benefits beyond stronger teeth, such as reduced brain fog, improved mood and most notably — “increased energy.”
“I have only been taking this for 8 days, so I can’t speak as to what it will do for my teeth, but I feel amazing,” one impressed reviewer shared. “Increased energy, less anxiety, clarity of mind, more endurance at the gym. Just overall well-being.”
A few months later, they came back with an update: “My teeth are no longer sensitive; I can even chew ice. I no longer need to allow my fruit to warm up before eating it. I am so impressed with these results.”
The teeth and gum benefits make sense. The formula’s key ingredient — calcium is an essential mineral that is stored primarily in the bones and teeth, where it helps provide strength and support.

But there’s also science suggesting the formula’s ingredients may offer energy-related benefits.
Alongside calcium, the formula contains vitamin D3, which helps the body absorb and use calcium. In addition to supporting immune function and bone health, vitamin D3 also plays a role in regulating muscles and nerves, and it can support healthy energy levels, too.
A study found that vitamin D treatment significantly improved fatigue in otherwise healthy people with vitamin D deficiency.
According to the Cleveland Clinic, approximately 35% of adults in the United States have vitamin D deficiency — which may help explain why this popular tooth supplement could also support healthy energy levels.
As with any new supplement, be sure to consult your physician prior to use.
