At the same time, research suggests that getting as much of your calcium from your diet, rather than supplements is a good idea. For instance, there is some evidence that the calcium intake from food is better for bone mineral density than the same calcium intake from supplements[17]. Foods that are high in calcium include dairy, leafy green vegetables, fish with edible bones, tofu made with calcium sulfate, and calcium-fortified foods and beverages.
Ketostix are very unreliable. There are many factors which can alter results such as hydration level, if you’ve worked out recently and the amount of unused ketones in your body to name just a few. Never rely of Ketostix to determine whether you are in ketosis or not. The Precision Xtra blood ketone monitor is the gold standard for testing for ketones in your body. After following a ketogenic diet for a while, you should be able to tell if you are in ketosis or not by the way you feel.

Participants consumed 13.2−1 of βHB (6.6−1 or 1,161 mg/kg of KE) over 9 h, either as 3 drinks of 4.4−1 of βHB at 3 h intervals (n = 12), or as an initial bolus of 4.4−1 of βHB given through a nasogastric tube, followed by an infusion of 1.1−1, beginning 60 min after the initial bolus, for 8 h (n = 4). Two participants completed both conditions (total n = 14). In both conditions, the KE was diluted to 1.5 L using the same citrus water as used in Study 2.

As stated above, there appears to be a difference between supplemental and dietary calcium intake, which can be important to keep in mind.  One study found aggregate calcium intakes above 1400 mg per day (from dietary and supplemental intake combined) to be associated with higher death rates, cardiovascular disease, and ischemic heart disease in women[15]. A 2014 meta-analysis found an association between dietary calcium intake and cardiovascular mortality[16]. The meta-analysis actually found a u-shaped relationship, where dietary calcium intakes that were both lower and greater than 800 mg/day were gradually associated with increased risk of cardiovascular mortality.
However, it's important to NEVER overlook the power of exercise and of course sticking to a proper routine to get the most optimized results. The most common mistake people make is by treating any keto supplement like a "wonder drug" that will help them shed weight in their sleep. Seriously... how is that even scientifically possible. So if you are thinking about trying out a particular keto supplement, I would suggest two things:
Hi. Thanks for the informative article! I have fallen down the exogenous ketone rabbit hole for the last 2 days trying to figure everything out. I am currently on a nutritional ketonic diet but after 8 months, I am finding it difficult to stay on it 100%. I would like to remain on a low-carb diet, but also have a little more flexibility in my food choices. If you take the expense out of the equation, which product would you recommend for someone who wants to use ketosis as a method of weight loss? Thank you so much.
Personally, I do this on Friday night to Saturday night, so if something happens and my hunger hasn't crashed by Sunday morning, I have another day that I can go zero carb to keep the momentum going. While the body will trigger ketosis as soon as you run out of glycogen, hunger is attached to your triglyceride and insulin levels, which might take an extra day to normalize.
Caveat emptor: the following post doesn’t come close to answering most of these questions. I only document my experience with BHB salts (and a non-commercial version at that), but say little to nothing about my experience with BHB esters or AcAc esters. But it will provide you will some context and understanding about what exogenous ketones are, and what they might do for athletic performance. We’ll likely podcast about the questions and topics above and cover other aspects of exogenous ketones in more detail.
