For Women Over 40
Strong Bones. Lean Muscle. Clean Protein.
After 40, your body needs more protein — not more ingredients. Primal Core delivers 24g of grass-fed whey per sachet with zero sweeteners, zero gums, and zero bloating. Designed for women who want to protect muscle, strengthen bones, and fuel their body without compromise.
The Shift
After 40, the Rules Change. Your Protein Should Too.
As estrogen declines, your body becomes less efficient at building and maintaining muscle — a phenomenon called anabolic resistance. The same amount of protein that built muscle at 25 no longer works at 45. You need more protein, better protein quality, and strategic timing to maintain the lean, strong body you've worked for.
The Timeline
What Happens to Muscle & Bone After 40
Perimenopause Begins
Estrogen fluctuations start. Muscle protein synthesis slows. Protein needs increase from 0.8g/kg to 1.2g/kg minimum.
Menopause Transition
Bone density drops 2–3% per year around menopause. Lean mass decline accelerates. Resistance training + protein becomes critical.
Post-Menopause
Anabolic resistance means muscles need more protein per meal (30–40g) to maintain the same response. Protein quality matters more than ever.
Why Primal Core
Designed for Your Body After 40
Preserve Lean Muscle
After 40, women lose 3–8% of muscle mass per decade. 24g of complete protein per sachet provides the leucine threshold needed to overcome anabolic resistance and stimulate muscle repair.
Support Bone Density
Whey protein contains calcium-binding peptides and amino acids that stimulate osteoblast activity. Higher protein intake is associated with significantly better bone mineral density in postmenopausal women.
Hormone-Friendly
Zero phytoestrogens (no soy), zero artificial sweeteners that may affect insulin sensitivity, zero endocrine-disrupting seed oils. Just clean, grass-fed whey that works with your body.
Gut-Gentle Formula
No gums, no sweeteners, no soy lecithin — the additives that cause bloating. Grass-fed concentrate retains natural immunoglobulins and lactoferrin that actively support gut health.
Steady Energy
Protein stabilizes blood sugar and reduces the energy crashes that become more frequent during hormonal shifts. A morning protein cappuccino sets a stable metabolic foundation for the day.
Skin & Collagen Support
Whey provides glycine and proline — key amino acids for collagen synthesis. Combined with vitamin C, adequate protein intake helps maintain skin elasticity and joint health.

Questions
Protein & Women Over 40 FAQ
How much protein do women over 40 really need?+
Research recommends 1.2–1.6g of protein per kg of body weight for women over 40 — significantly higher than the outdated 0.8g/kg RDA. For a 65kg woman, that's 78–104g daily. This elevated intake is essential because muscle protein synthesis becomes less efficient with age (a phenomenon called "anabolic resistance"), meaning you need more protein to achieve the same muscle-building response you had at 25.
Does estrogen decline affect protein needs?+
Yes, dramatically. Estrogen is protective of both muscle and bone tissue. As estrogen declines during perimenopause and menopause, women lose muscle mass at an accelerated rate — up to 3–5% per decade after 30, increasing to 8% per decade post-menopause. Simultaneously, bone density drops 2–3% annually in the years around menopause. Higher protein intake combined with resistance training is the most effective strategy to counteract both.
Can whey protein help with bone density?+
Yes. Whey protein is rich in calcium-binding peptides and contains the amino acids needed to stimulate osteoblast activity (bone-building cells). A 2019 meta-analysis in Osteoporosis International found that higher protein intake was associated with significantly higher bone mineral density and lower fracture risk, particularly when combined with adequate calcium and vitamin D.
Will whey protein make me bulky?+
No. Women have 15–20x less testosterone than men, making it physiologically impossible to "bulk up" from protein supplementation alone. What protein does is preserve and build lean, toned muscle tissue — which is exactly what counteracts the soft, undefined look that comes with age-related muscle loss. More protein = firmer, stronger, leaner body composition.
Why does my stomach bloat with most protein powders?+
Most protein powders contain 15–25 additives: artificial sweeteners (sucralose, acesulfame-K), thickening gums (xanthan, guar), soy lecithin, and seed oils. These are the true bloating culprits — not the whey itself. Primal Core contains exactly one ingredient: grass-fed whey protein concentrate. Zero additives means zero digestive compromise.
What is the best time for women to take protein?+
Distribute protein evenly across 3–4 meals, with 25–35g per meal. Research shows that the "muscle full" effect — where muscle stops absorbing protein — resets every 3–4 hours. A morning protein cappuccino (24g from Primal Core) sets the foundation. Add Greek yogurt at lunch, a protein snack mid-afternoon, and lean protein at dinner to hit your daily target.
