But physiologically speaking, it might be generally better to have sex in the morning because many people’s bodies have higher levels of testosterone and estrogen, two hormones that influence sexual desire1, at the start of the day. That means you may be more in the mood and potentially able to have more satisfying sex in the morning. RELATED STORY: Sex And The Mind: How To Hack Your Brain For Better Sex For men and people with penises, testosterone levels replenish overnight and thus tend to be at their highest in the morning and at their lowest at night....

That, folks, is where supplements come into play: Trusted nutrition and medical experts recommend 5,000 I.U. of vitamin D3 (the body’s preferred form) per day to help you get to—and stay!—above that 50 ng/mL threshold. But here’s the thing: That’s old-school science. While vitamin D toxicity is possible, it’s much more challenging to reach than you might think—so there’s really no excuse for brands not to up the ante. The risk of toxicity is not even relevant at useful, science-backed supplement doses, Ferira says....

I mean, can you imagine summer without them? I can’t. To see how the oh-so-iconic lemon oil fares when put to the test, we sought out scientific research to back up its presumed effects....

This style of dating sounds devastatingly romantic, but when it’s this sugarcoated, it’s often not actually an accurate representation of love. If you’ve recently met someone and it mirrors this experience, it can seem like a dream come true instead of what it really is: limerence. At first glance, limerence doesn’t sound all that different from falling in love. In fact, it doesn’t sound negative at all to be that wowed by someone and adore them wholeheartedly....

Needless to say, regardless of your current eye prescription (or lack thereof), the need for proactive eye care is very real. This involves habits like taking regular screen breaks, getting enough sleep (yes, really!), and fortifying your diet and supplementation routine with targeted eye health nutrients—such as lutein and zeaxanthin, two of the star carotenoids in mbg’s eye health+. Carotenoids are sorted into two categories: xanthophylls and carotenes. The main difference lies within their molecular structure; xanthophylls contain oxygen, while carotenes do not....

So what’s the verdict on this integrative treatment, and does it warrant the fanfare? We investigated. It is not the only way to support NAD+ levels in the body, of course. It is also possible to increase NAD+ levels through oral supplementation of one of its precursors, such as niacin (vitamin B3), nicotinamide, and nicotinamide riboside (NR), the last option being a direct precursor2, and has been shown to be the most effective at supporting your natural levels of NAD+....
