500-1000mg extract twice daily

Ayurvedic herb traditionally used to support lactation and reproductive health

5 studies | 200 participants

1-2g seeds as tea 2-3x daily

Contains anethole which may have estrogenic effects supporting milk production

4 studies | 150 participants

Brewer's YeastC

1-2 tablespoons daily

Traditional remedy rich in B vitamins, iron, and chromium; anecdotally increases milk supply

2 studies | 80 participants

IodineA

150-290mcg daily total (diet + supplement)

Essential for thyroid function and infant brain development; breastfeeding mothers have increased needs

15 studies | 2,000 participants

Omega-3 Fatty Acids (DHA)A

200-400mg DHA daily

DHA is essential for infant brain development and is transferred through breast milk

20 studies | 3,000 participants

Vitamin DA

2000-6000 IU daily (higher doses if not giving infant vitamin D)

Breast milk is low in vitamin D; maternal supplementation increases milk vitamin D content

15 studies | 1,500 participants

How It Works

Breast milk is the optimal nutrition for infants, providing perfect nutrition, immune protection, and bonding benefits. However, many mothers experience concerns about milk supply. While most women can produce adequate milk with proper support, certain herbal supplements (galactagogues) may help increase production. Additionally, the nutritional quality of breast milk depends on maternal nutrition, making certain supplements important for both mother and baby.

IMPORTANT: Most perceived low milk supply is actually adequate supply with normal variations. Before using galactagogues, ensure proper latch, frequent feeding, and adequate hydration/calories. Consult a lactation consultant for breastfeeding concerns. Some supplements may not be suitable for all mothers.

•Fenugreek is the most commonly used and studied herbal galactagogue. It has a long history of traditional use for increasing milk supply. Most mothers notice an increase within 24-72 hours, and a telltale sign it's working is a maple syrup-like smell in sweat and urine. It's generally considered safe but should be avoided by those with legume allergies or those taking blood thinners.

•Moringa is a nutrient-dense plant used in the Philippines and other cultures to support lactation. Studies show it may significantly increase breast milk production. It's also rich in vitamins and minerals that benefit both mother and baby.

•Blessed Thistle is traditionally used alongside fenugreek for a synergistic effect. While less studied on its own, it's a common component of lactation tea blends.

•Shatavari is an Ayurvedic herb whose name means 'she who possesses a hundred husbands,' reflecting its traditional use for female reproductive health. It's used to support milk production and postpartum recovery.

•Fennel contains anethole, a compound with mild estrogenic properties that may support milk production. It's traditionally used as a tea.

•Brewer's Yeast is rich in B vitamins, iron, and chromium. While scientific evidence is limited, many mothers report it helps with milk supply and energy levels.

•Iodine is essential during breastfeeding because the infant relies on breast milk for thyroid hormone development and brain development. Breastfeeding mothers need significantly more iodine than non-lactating women.

•Omega-3 Fatty Acids (DHA) pass through breast milk and are critical for infant brain and eye development. Maternal DHA supplementation increases the DHA content of breast milk.

•Vitamin D in breast milk is typically insufficient for infant needs unless the mother takes higher doses. Either the mother should supplement with higher-dose vitamin D or the infant should receive vitamin D drops.

Expected timeline: Fenugreek and other galactagogues: often 24-72 hours to see increased supply. Nutrients (DHA, iodine, vitamin D): provide ongoing nutritional support throughout breastfeeding.

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.
