Boost Hair Growth with Calcium

Calcium plays a vital role in regulating hormones and enzymes, including those involved in healthy hair growth. It contributes to the structural integrity of hair follicles, promoting strong and healthy hair strands. Calcium also supports healthy cell division and differentiation, processes that are essential for hair development.

Calcium to Phosphorus Ratio

Are you a meat lover? While a protein-rich diet has many benefits, the naturally high phosphorus and low calcium content in meat can disrupt your body's delicate mineral balance. This imbalance triggers increased production of parathyroid hormone (PTH) to compensate lack of calcium in the diet.

Without enough calcium increased PTH can lead to bone loss as your body compensates by pulling calcium from your bones to balance the high phosphorus levels from meat consumption (and grains and legumes too).

Additionally, too much phosphorus is inflammatory and can disrupt thyroid function, potentially causing fatigue, weight changes, and other health concerns.

The Solution:

Protect your bones and thyroid by incorporating eggshell calcium powder into your diet. This natural supplement provides a readily available source of calcium, restoring the crucial calcium-to-phosphorus ratio and helping to counteract the negative effects of excess phosphorus from meat, grains and legumes.

While we always advocate prioritizing calcium-rich foods, such as dairy, our eggshell calcium powder offers a natural and convenient way to supplement your intake. It complements dairy beautifully, ensuring you maintain optimal calcium levels for strong metabolic health.

Essential for Thyroid Hormone Production

Calcium plays a role in influencing the production of thyroid hormones. It acts as a signaling molecule within the thyroid gland's cells, helping to regulate the synthesis and release of thyroid hormones. Maintaining adequate calcium levels is important for ensuring optimal thyroid function.

Great product!

So far I’m loving this product! Super easy to incorporate into my morning coffee or smoothies.

Another hit

I've backed out of the instagram/influencer health world for a while now. My health seemed to be getting worse instead of better, no matter how many hundreds of thousands of dollars I was spending on every next new thing. Parasites, mold, endless name it, there's something to buy for it. Once I stopped taking everything, I was able to intuitively begin picking out supplements that my body was saying yes to. This is one of them. I'm taking this with the pearl/oyster capsules, as well as the B vitamin drops. I can tell my body is needing these, and that's not something I've ever noticed with other products. Slowly, along with a few other changes, my energy and life force is coming back. I can't say enough good things about this brand, and I'm so happy I've rediscovered it.

Goes well in everything

I’ve been adding this to lattes and hot chocolates for extra calcium for myself and my girls! Super happy with it!
