Supplements by Age

Know what your body needs, when to take it, and how your cycle plays a role. No more guessing.

Women have unique nutritional needs that shift throughout our lives. These are general guidelines to help you start conversations with your healthcare provider — not a replacement for personalized advice.

Ages 18-29

Focus: Building foundations, cycle health, energy

Iron

Best time: Morning, with food
Cycle note: Needs increase during your period. If you have heavy flows, consider tracking intake around days 1-5.

Supports oxygen transport and energy. Many women in this age range are low due to menstruation.

Vitamin D

Best time: Morning
Cycle note: Can support mood stability throughout the cycle.

Essential for bone health, immune function, and mood. Especially important if you're indoors a lot or live in northern climates.

B-Complex

Best time: Morning
Cycle note: B6 can help with premenstrual symptoms.

Supports energy, brain function, and stress management. Great for active lifestyles and high-stress periods.

Magnesium

Best time: Evening
Cycle note: May help with cramps and sleep around your period.

Supports muscle function, sleep, and stress. Many women are deficient. Glycinate and citrate forms are well absorbed.

Omega-3

Best time: With a meal containing fat
Cycle note: DHA supports brain health and may ease mood changes.

Anti-inflammatory, supports heart and brain health. If you don't eat fatty fish regularly, consider a fish oil or algae supplement.

Folate (Methylfolate)

Best time: Morning
Cycle note: Essential if trying to conceive. The active form (methylfolate) is better absorbed than folic acid.

Critical for cell division and energy. The methylated form is particularly helpful if you have MTHFR gene variations.

Ages 30-39

Focus: Sustaining energy, fertility support, stress resilience

CoQ10

Best time: Morning with fatty food
Cycle note: Supports egg quality and ovarian function. Consider if trying to conceive.

Antioxidant that supports cellular energy, heart health, and fertility. Ubiquinol is the absorbable form.

Iron

Best time: Morning, with food
Cycle note: Needs peak during menstruation. Track your energy patterns around your cycle.

Continued emphasis on iron as periods can remain heavy. Supports energy and cognitive function.

Vitamin D + K2

Best time: Morning
Cycle note: K2 helps direct calcium properly. Important as estrogen begins to shift.

K2 works with D3 to direct calcium to bones instead of arteries. Essential for long-term bone and heart health.

Ashwagandha

Best time: Evening or split doses
Cycle note: May help regulate cortisol throughout the cycle, especially in the luteal phase.

Adaptogen that helps manage stress and support adrenal health. Supports sleep and reduces anxiety.

Collagen

Best time: Any time, on empty stomach
Cycle note: Supports skin elasticity and joint health as you move through your 30s.

Supports skin, hair, nails, gut lining, and joints. Peptide forms are best absorbed.

Probiotic

Best time: Morning, before breakfast
Cycle note: Look for strains like Lactobacillus and Bifidobacterium for vaginal and gut health.

Supports gut microbiome, immune function, and nutrient absorption. A quality daily probiotic matters.

Ages 40-49

Focus: Perimenopause prep, hormonal shift, bone health

Magnesium

Best time: Evening
Cycle note: Can be especially helpful for sleep disruptions and mood swings during perimenopause.

Critical for this transition. Supports sleep, mood stability, and eases hormonal headaches and hot flashes.

Calcium

Best time: Evening, with food
Cycle note: Estrogen decline accelerates bone loss. This is the decade to prioritize bone health.

Women lose bone density faster as estrogen declines. 1200mg daily total from food + supplements is the target.

Vitamin D + K2

Best time: Morning
Cycle note: Pair with calcium for maximum bone support.

Non-negotiable for bone health and cardiovascular protection as you move toward menopause.

Black Cohosh

Best time: Morning and evening
Cycle note: Traditionally used for hot flashes and night sweats. Evidence is mixed but many find it helpful.

Herbal support for menopausal symptoms. Start low and check in with your practitioner.

Omega-3

Best time: With a meal containing fat
Cycle note: EPA supports mood stability during hormonal shifts.

Anti-inflammatory support becomes even more important. Supports heart, brain, and mood through the transition.

SAMe

Best time: Morning, on empty stomach
Cycle note: May support mood and joint health during perimenopause.

Supports mood, liver function, and joint health. May help with low-grade depression and energy.

Ages 50+

Focus: Menopause management, heart health, longevity

Collagen + Hyaluronic Acid

Best time: Morning, on empty stomach
Cycle note: Skin dryness increases post-menopause. Hyaluronic acid helps retain moisture.

Supports skin elasticity, joint comfort, and connective tissue. A popular combination for this life stage.

Magnesium

Best time: Evening
Cycle note: Sleep and mood support remain critical. May help with ongoing hot flash management.

Continues to be one of the most important supplements for women post-menopause.

Cardiovascular protection is key post-menopause. Anti-inflammatory effects support overall longevity.

Vitamin D + K2

Cycle note: Bone density monitoring is important. Work with your doctor on appropriate D3 dosing.

Remains essential for bone retention and cardiovascular health.

Probiotic

Best time: Morning, before breakfast
Cycle note: Gut health affects everything from immunity to mood to nutrient absorption.

Diversity of gut bacteria becomes increasingly important for overall health and longevity.

Turmeric / Curcumin

Best time: With fatty food
Cycle note: Anti-inflammatory benefits support joint comfort and heart health.

Powerful anti-inflammatory. Look for formulations with piperine (black pepper) for better absorption.

How Your Cycle Affects Nutrient Needs

Your hormones fluctuate throughout the month, and so can your nutritional needs. Here's a general guide:

Menstruation (Days 1-5)

Iron needs are highest. Consider extra magnesium if experiencing cramps. Focus on anti-inflammatory foods.

Follicular (Days 6-14)

Energy tends to rise. Good time to focus on B vitamins and nutrients that support detoxification (like folate and magnesium).

Ovulation (Day 14-16)

Testosterone and estrogen peak. Some women feel most energetic. Continue core supplements.

Luteal (Days 17-28)

Progesterone rises. Many women experience PMS, mood shifts, and fatigue. Magnesium and B6 can be especially helpful. Reduce salt and caffeine if experiencing bloating.

General Guidelines

  • Consult your doctor before starting new supplements, especially if you take medications or have health conditions.
  • Quality matters — look for third-party tested brands (NSF, USP, ConsumerLab).
  • Food first — supplements supplement a healthy diet, they don't replace one.
  • Track how you feel — everyone's body is different. Notice patterns around your cycle, sleep, and energy.
  • Blood work — get your levels checked periodically. You might be low in something without obvious symptoms.
