Estrogen and collagen

[Bernadette_Abraham]

Hi @ivona_n – great questions.

1. Yes, triclosan is an estrogen mimicking antibacterial chemical found in soaps, toothpaste and other personal care products, but the good news is that it’s been banned in antibacterial soaps in many countries, including the US and EU due to safety concerns. But it’s still important to read product labels because it might still be included in toothpaste, mouthwash, deodorants, cosmetics and hand sanitizers.

Dr. Bronner’s doesn’t have triclosan listed in the active ingredient so you’re good.

Anytime a product says “antibacterial or germ-fighting” though, read the ingredients to avoid triclosan or the chemical ingredient name: 5-chloro-2-(2,4-dichlorophenoxy)phenol.

And since you’re on the low-tox journey, also know that Bisphenols (ex. BPA, BPS, etc) from plastics, Glyphosate and other pesticides, and phthalates (anything with “fragrance” or long-wear like waterproof mascara) are all estrogen mimickers too. So do your best to avoid these too as much as possible.

2. Regarding arginine. Collagen powder is naturally high in arginine, and yes, can be a trigger for some people prone to cold sores. If you’d still like to take collagen, one option is to balance it with a lysine supplement (around 500–1,000 mg per day), especially during times of stress or when you’re actively using collagen. You can also look for collagen products that list their amino acid profile and choose one with lower arginine content if available.

You can also increase lysine-rich foods and decrease arginine-rich foods to help bring a better balance.

Highest in lysine (increase these foods):

• Eggs

• Beef, lamb, chicken, turkey

• Fish (especially cod, sardines, tuna, and salmon)

• Cheese (particularly Parmesan and cheddar)

• Yogurt and kefir

Highest in arginine (reduce these foods):

• Nuts (especially peanuts, almonds, walnuts)

• Seeds (especially sunflower and sesame)

• Chocolate

• Coconut

• And of course, gelatin/collagen (due to its natural amino acid profile)

Hope this helps!
