HMR's 4-in-1 chewable combines lignan, melatonin, biotin and milk thistle in a beef flavored tablet aimed at dogs whose adrenal function, skin, coat or digestion could use extra support, and it holds a solid 4.4 star average, though the review count is still fairly small.
Dogs who could use extra adrenal and cortisol support alongside general skin, coat and digestive care, especially owners who want a single combination chew rather than separate single-ingredient supplements.
Skip if
You want a supplement targeting only one specific issue, such as skin alone or digestion alone, since this is formulated as a broad 4-in-1 blend, or your dog has a diagnosed adrenal condition, since any hormone-related supplement should be reviewed by a vet first.

Overview
["HMR's chewable tablet brings together four ingredients, lignan, melatonin, biotin and milk thistle, in one beef flavored tablet, positioned as a 4-in-1 formula rather than a single-purpose supplement.", "The label points to adrenal support and maintaining normal cortisol levels as a core benefit, alongside general skin, coat and digestive health, so it's built for dogs whose owners want broad wellness coverage in one chew rather than stacking multiple bottles.", "At $22.91 for 90 chewable tablets, it's priced in the middle of the pack for combination supplements, and its 4.4 star rating across a modest review base suggests early buyers are largely satisfied, though the track record is still building."]
Pros
Combines four supportive ingredients, lignan, melatonin, biotin and milk thistle, in one chew
Beef flavor designed for easy at-home dosing
Positioned for adrenal and cortisol support alongside skin, coat and digestion
Solid 4.4 star average rating
Cons
Review count is still small, so long-term feedback is limited
Milk thistle and melatonin combinations are best discussed with a vet if your dog is on other medications
Broad 4-in-1 formula means it isn't a targeted fix for a single issue
Performance notes
Milk thistle is commonly used to support liver function, melatonin is often used for calming behavior and cortisol regulation, biotin supports skin and coat, and lignans are plant compounds sometimes used for hormone balance support. Combined in a chewable tablet with beef flavor, the formula is built for daily use rather than an occasional treat.
What buyers say
With 54 reviews averaging 4.4 stars and about 200 bought in the past month, this is a smaller volume product with a positive early track record, though it hasn't yet built the review base of longer established antioxidant supplements in this category.
Melatonin is commonly used to support calm behavior and is believed to play a role in regulating cortisol, which is why it's paired with adrenal support ingredients here. It is not a sedative and shouldn't be used to treat anxiety without a vet's guidance.
Can this be given alongside other supplements or medications?
Because milk thistle and melatonin can interact with certain medications, check with your vet before adding this chew if your dog is already on prescription medication or another supplement routine.
Is this formulated for a specific health condition?
This is a general wellness chew aimed at adrenal, skin, coat and digestive support rather than a treatment for a diagnosed condition, so dogs with a specific medical issue should be evaluated by a vet first.
