Ca-AKG + Calcium
Can you take Ca-AKG and Calcium together?
Yes, but count the calcium in Ca-AKG (about 200 mg per gram) toward your daily total.
What to do. Keep total calcium from food and supplements under the adult upper limit of 2,000–2,500 mg/day (depending on age). Many people on Ca-AKG can lower their separate calcium dose.
Mechanism
Ca-AKG adds to your calcium total
Ca-AKG is a calcium salt, so it delivers calcium on top of any calcium supplement and your diet. Too much calcium from supplements is linked to kidney stones.
Evidence: Strong evidence — Randomized trials, meta-analyses or clinical guidance that directly support this specific claim.
