Too much(i.e.toxic) D3 would be over 10,000 units per day, everyday for a few months. This is pretty average. It's much more likely that people are deficient rather than in excess of vit D, especially for the average person spending most of their time indoors.
It's just a bad deal, as you can buy D3 and K2 separately much cheaper than this.

I'm a physician and what people are saying all have their truth:
- If you don't have blood test showing that you're deficient, then I'd say taking ~1k IU would be appropriate
- If you're vitamin D is low or low normal, then taking 2-5k IU could be appropriate based on doctor's recommendations
- Sports Research is a very high quality brand, and
worth the premium to know you're getting what you're paying for

You should really have a blood test done to know if you even need D supplementation in the first place. From what I have read, you really don't wanna be getting too much D.

Anyone else thinking these are extremely 'spensive on per serving basis? I understand it's 5000 IU, but wow...

For me, it's worth it. I've tried different kinds of D3+K2 and this seems to be the most effective.
The difference was night and day when I figured out I was D deficient. Days are way happier and life outlook better. Get a blood test or a DNA test. Though a lot humans are deficient.

It's definitely not a bad deal. Sports Research is top-notch when it comes to supplements and they back it up with their 3rd party testing.

Harvard Health:
If you're taking a vitamin D supplement, you probably don't need more than 600 to 800 IU per day, which is adequate for most people. Some people may need a higher dose, however, including those with a bone health disorder and those with a condition that interferes with the absorption of vitamin D or calcium, says Dr. Manson. Unless your doctor recommends it, avoid taking more than 4,000 IU per day, which is considered the safe upper limit.

Bulk Supplements [amazon.com] has a similar product on Amazon. It's currently $5 off, so $14.77 w/ 5 S&S for me and 365 servings. I don't know if it's as good as this SR brand here or from the Costco deal frequently brought up, but it's definitely cheaper.

I would not get the 5,000 IU one and would get the 2,500 IU one as this is within the safe limit and is still on sale.

I take 8k of D3 a day. I work nights and am over 50. What's the symptoms for taking too much? I immediately felt my joints get better after a few days but now I'm concerned if I'm taking too much.
