Are they something to worry about if they happen once around 1.5 weeks?

Unlike the name indicates, it is not a single compound. Instead its a blanket term for a group of active unsaturated molecules including: - Retinoids - Retinol - Retinaldehyde - Retinoic acid - Provitamin A Carotenoids - Beta-carotene - Alpha-carotene - Gamma-carotene - Beta-cryptoxanthin - Alpha-cryptoxanthin A provitamin is a substance that can be converted into a vitamin within the body. It is a precursor to the active form of a vitamin and usually requires a metabolic conversion before it can fulfil the functions of the vitamin. In this example, carotenoids are converted into active vitamin A (retinol) in the body. Beta-carotene is the most well-known and studied provitamin A carotenoid. The recommended daily intake for vitamin A for a normal sized male is about 900-3000 μg/day of retinal, retinol, or retinoic acid, or about 12-24 times that of carotenoids, since they have a significantly lower bioavailability in the human body and are also poorer sources of the active vitamin A. What does Ray Peat say about Vitamin A? "I found that I had an extremely high vitamin A requirement, increased by stress or bright light, and that it was related to thyroid function. Usually, thyroid and vitamin A are the supplements that stop acne. I avoid carotene, because it blocks thyroid and steroid production, and very large, excessive, amounts of vitamin A, retinol, can do the same. I use halibut liver oil-derived vitamin A, or retinyl palmitate. The toxic effects of extremely big doses, such as 500,000 to a million i.u., seem to be from either oxidative processes (rancidity) that are prevented by adequate vitamin E, or by antithyroid effects. I found that when my need for vitamin A began to decrease I tended to accumulate carotene in my calluses; that happens when the thyroid function is lower, reducing the need for vitamin A. Since you are eating foods with carotene, the calluses on your palms or soles should serve as an indicator of when your tissues are saturated with vitamin A. About 100 i.u. of vitamin E would help to keep the vitamin A from being wasted by oxidation, and possibly could reduce your requirement for it.”

Can someone make a post on vitamin a if you dont want to eat liver. I know aleks takes it topical, but what dosages and how often and what brand.

Could you please suggest some protein sources for a vegetarian apart from eggs.

“Because of contaminants in supplements, I seldom recommend the oral use of any of them. Supplements usually contain contaminants that can cause allergic reactions when they are used for a long time. Allergic reactions sometimes show up within a few minutes of contacting your mouth, other times it takes a couple of days to see a bad reaction. Most supplements contain enough impurities to eventually cause problems.” - Ray Peat 1. According to this clinical trial, 600 mg of Tongkat Ali extract (1.45% eurycomanone; 8.5mg total) increased young (average age 24 years) males’ total testosterone from 802 to 924 ng/dl in just 14 days (tongkat Ali is also an adaptogen). 2. In this animal study, the water extract of Fadogia increased testosterone 6 fold in albino rats after just 5 days. Studies have shown that doses over 18 mg/kg (the 50 and 100 mg/kg doses) had side effects as it caused liver, kidney and testicular damage. 3. Maca root didn’t affect LH, testosterone production or estradiol. 4. Fenugreek has been shown to increase testosterone, improve muscle strength and size, help with fat loss and protect the liver against toxins, such as alcohol. Conclusion: the above supplements display a positive effect on testosterone (except maca). Personally, through experience and other people’s feedback. And looking at other supplements like ashwagandha, also an adaptogen, which has been shown in studies to boost testosterone levels, but is accomplished by numbing your emotions. (Less stress = more testosterone… but at what cost?)
