Nutrition
What the research says about eating in perimenopause. Higher protein, key micronutrients, evidence-backed supplements.
Macronutrients
Protein Needs for Women Over 40
Women over 40 need 1.2-1.6 grams of protein per kilogram of body weight per day — roughly double the official RDA. Hit 30-40 g per meal to trigger the muscle protein synthesis response, which becomes less sensitive (anabolic resistance) with age.
Fiber for Women in Perimenopause
Women in perimenopause need 25-35 g of fiber per day. Beyond digestion, fiber feeds gut bacteria that influence estrogen recycling and inflammation. Most women get 12-15 g — half the target.
Micronutrients
Calcium and Vitamin D for Women Over 40
Women over 40 need 1,200 mg calcium and 800-1,000 IU vitamin D per day. Food first when possible; supplement if intake or sun exposure is low. Both are necessary but not sufficient — bone health requires mechanical loading (strength training) too.
Omega-3 for Women Over 40
Aim for 1-2 g of combined EPA + DHA daily, ideally from fatty fish 2-3 times per week. Supplementation is reasonable if fish intake is low. Benefits include reduced joint inflammation, better mood, and cardiovascular protection.
Supplements
Creatine for Women Over 40
Yes — creatine monohydrate (5 g/day) is one of the most evidence-backed supplements for women over 40. Benefits extend beyond muscle: improved cognitive function, better recovery, possible bone density support, and no meaningful side effects in healthy women.
Magnesium for Women Over 40
Most women over 40 are subclinically magnesium-deficient. 300-400 mg/day of magnesium glycinate or citrate supports sleep, mood, muscle recovery, and bone mineralization. It is one of the few supplements with broad evidence for perimenopausal symptom relief.
Collagen for Women Over 40
Collagen peptides (10-20 g/day) have moderate evidence for skin elasticity and joint comfort. The benefits are real but modest — not the transformation marketing suggests. As a supplement, it works; as a hero ingredient, it does not.
Eating patterns
Mediterranean Diet for Perimenopause
The Mediterranean diet — built around vegetables, olive oil, fish, legumes, nuts, and whole grains — is the most evidence-backed eating pattern for women in perimenopause. It supports hormone balance, reduces inflammation, and protects cardiovascular and cognitive health.
Sugar Cravings in Perimenopause
Sugar cravings spike in perimenopause due to fluctuating estrogen, declining serotonin, and worsening insulin sensitivity. The fix is not willpower — it is structural: stabilize blood sugar with protein-forward meals, manage sleep, and treat cravings as information.
